Project Title Zoho + Supabase Developer / Team for Data Migration & Ongoing Backend Support Project Description We are looking for an experienced Zoho developer, backend developer, or small development team to help migrate data from our existing Zoho environment into a new Supabase/PostgreSQL backend. This project may also develop into ongoing backend development and maintenance work through Freelancer.com after the initial migration is completed. Our organization currently uses Zoho Recruit, Zoho CRM, Zoho Books, and other Zoho applications to manage recruitment, candidates, employers, clients, and operational data. We are developing a new recruitment and job platform with Supabase/PostgreSQL as the primary backend. The platform already has an initial backend and application architecture in development. We are looking for someone who can first help with the Zoho → Supabase migration, understand the existing system, and potentially continue supporting the backend as the platform moves into production. Initial Scope The initial project will involve: Reviewing our existing Zoho Recruit / CRM environment Identifying relevant modules, fields, relationships, custom fields, workflows, and attachments Determining the appropriate way to extract data using Zoho APIs and supported Zoho development tools Mapping existing Zoho records into our Supabase/PostgreSQL schema Migrating candidate, employer/client, recruitment, job, and related operational data Preserving relationships between records Handling custom Zoho modules and fields Migrating or appropriately referencing documents and attachments Creating reusable migration scripts or tools rather than relying entirely on manual exports Validating migrated data for completeness and accuracy Documenting the migration process Where appropriate, establishing an incremental synchronization process between Zoho and Supabase during the transition Potential Ongoing Backend Work We are also interested in finding a developer or team that could potentially continue working with us after the initial migration. Future projects may include: Supabase/PostgreSQL maintenance Database schema development and migrations Backend API development Supabase Edge Functions Authentication and authorization Row-Level Security policies Storage and document management Zoho integrations Data synchronization Bug fixes and production support Database optimization Monitoring and deployment support Third-party integrations Development of additional backend features Technical documentation and system handover The immediate priority is the migration, but successful completion of this project may lead to additional projects and ongoing work on Freelancer.com. Preferred Experience We are looking primarily for demonstrated technical experience rather than certifications alone. Zoho certification or official Zoho Partner/Developer status is preferred, but not required. Candidates without formal certification are encouraged to apply if they have substantial experience developing with the Zoho ecosystem. Relevant experience includes: Zoho Recruit API Zoho CRM API Zoho Books API Zoho OAuth/API authentication Zoho custom modules and fields Zoho record relationships Zoho attachments/files Deluge Supabase PostgreSQL SQL REST APIs Backend development Database migrations ETL/data pipelines Authentication and authorization Production system maintenance Experience with ATS platforms, recruitment systems, HR software, or job portals would also be helpful. When Applying Please include: Your experience working with Zoho Recruit, Zoho CRM, or Zoho One Examples of projects where you worked directly with Zoho APIs or Deluge Any Zoho certifications or Partner credentials, if applicable Your experience with Supabase, PostgreSQL, or similar backend systems Any experience migrating Zoho data into external databases Whether you are an individual developer or part of a development team Whether you are available for potential ongoing backend development and maintenance through Freelancer.com A brief explanation of how you would approach a Zoho → Supabase migration Your availability and estimated timeline for the initial migration Please begin your proposal with “ZOHO + SUPABASE” so we know you have read the full project description. What We Are Looking For We already have an initial platform under development, so this is not a greenfield project. The ideal candidate(s) can: understand the existing backend → migrate the Zoho data → document the system → continue supporting and developing the backend if needed. We are open to either an experienced individual developer or a small technical team with strong Zoho and backend expertise.

Hello, I'm Denis, a full-stack developer specializing in data migrations, backend systems, and API integrations. I've completed several projects extracting data from legacy systems and building reliable ETL pipelines. ZOHO + SUPABASE I understand your project: migrating operational data from Zoho (Recruit, CRM, Books) into a clean Supabase PostgreSQL schema while preserving relationships and attachments. I have direct experience with Zoho APIs for data extraction, custom field mapping, and syncing related records across modules. I'm comfortable designing Supabase schemas, writing migrations, setting up Row-Level Security, and building scalable backend logic. My approach: 1. Audit your Zoho environment (modules, custom fields, relationships, attachments) 2. Build reusable extraction scripts using Zoho APIs 3. Create a mapping layer for field transformations and validation 4. Test scripts on a data subset before full migration 5. Document the process thoroughly Key considerations include managing Zoho's API rate limits and ensuring data consistency. I'd use batching and transaction management to prevent partial migrations and enable straightforward rollbacks. I'm available immediately and interested in supporting your backend through production. Let me know your timeline and I'll provide a detailed estimate. Thanks, Denis.

ZOHO + SUPABASE Your project requires migrating data from Zoho Recruit, CRM, and Books into Supabase/PostgreSQL while preserving record relationships, custom fields, and attachments. The key complexity is handling Zoho's custom modules and field mappings—each module has unique relationships that must be preserved. If successful, this could lead to ongoing backend work, so maintainable migration scripts are essential. I would start by mapping your Zoho schema to Supabase, then build reusable extraction scripts using Zoho APIs with pagination and rate limiting. I would handle attachments by migrating references or copying to storage, validate data completeness, and document the entire process. I have worked with Zoho APIs and Deluge, plus Supabase/PostgreSQL with ETL pipelines and production backend support. 1. Are attachments stored as file paths in Zoho or binary data, and do you need the actual files migrated to Supabase Storage or just references preserved? 2. Should the migration be a one-time cutover, or do you need incremental sync between Zoho and Supabase during the transition period? Reply with those answers and I can outline the migration timeline. Best regards, Opeyemi

ZOHO + SUPABASE This kind of project usually succeeds or fails on mapping and validation, not on the import command itself. You already have a backend in progress, so the first job is to understand how Zoho Recruit/CRM/Books data actually relates to your Supabase schema, then migrate it in a way that keeps records, custom fields, and attachments consistent instead of creating cleanup work later. My background is in API-based backend work, database migrations, PostgreSQL handling, and structured data transfers where custom modules and relationship preservation are critical. I’m also comfortable staying on after migration for backend maintenance, sync improvements, auth/RLS-related work, and production support if the first phase goes well. A few details would help narrow the first milestone: - Which Zoho apps are definitely included in the initial migration, and which are optional for later? - Do you need one-time migration only at first, or should incremental sync be included from the start? - Do you already have field mapping documentation, or should that be created from scratch during discovery?

ZOHO + SUPABASE Hello There! I'm Md Toriqul Islam, and I'm excited to partner with you & I can dive into your project immediately. I'm a Zoho and Supabase developer experienced in data migration and ongoing backend support for recruitment and CRM platforms. I understand you need Zoho Recruit, CRM, and Books data mapped and migrated into your Supabase/PostgreSQL backend, preserving relationships, custom fields, and attachments, with reusable migration scripts, data validation, documentation, and potential incremental sync during transition, plus availability for ongoing backend support afterward. I've handled similar Zoho to external database migration projects before. I am skilled in Zoho Recruit and CRM APIs, Deluge, Supabase, PostgreSQL, and ETL pipeline development. I have some questions: 1. Roughly how many records and custom modules are involved, and are attachments stored in Zoho's own file storage or an external system? 2. Do you need a one-time full migration only, or should the incremental sync process stay active during a transition period before full cutover? I'm ready to start right away and happy to discuss any details. Looking forward to hearing from you. Best regards, Md Toriqul Islam

ZOHO + SUPABASE I can map Zoho's complex relationships to Supabase's schema while preserving data integrity, rather than treating it as a flat export. I migrated a Zoho CRM to PostgreSQL with 10,000+ records, handling custom fields and attachments—took 3 weeks instead of 6. I'd approach this using Supabase's schema migrations because it allows incremental syncs while avoiding manual ETL scripts. The biggest improvement will come from setting up row-level security policies early to match Zoho's permission models. This will reduce future support requests by making the data structure self-documenting. I provide two weeks of bug fixes and improvements after the migration, even after the project is done. If we're aligned, I'd be happy to review your existing Supabase schema and suggest the safest approach before making any changes. Thanks, Lazar.

ZOHO + SUPABASE Hi, The main migration risk is losing Zoho relationships, custom fields, attachments, or operational data when moving into Supabase. I can map your Zoho Recruit CRM structure to the existing PostgreSQL schema and build a reliable, reusable migration process with proper validation. I’ll handle Zoho API OAuth extraction, data transformation, relationship mapping, attachments, staged migration, and reconciliation. The timeline will remain flexible and will be confirmed after reviewing your data volume and schema complexity. After migration, I can also provide ongoing Supabase, PostgreSQL, API, Zoho integration, and backend support. Can you share your current Zoho modules and Supabase schema so I can assess the migration scope? Best regards, Akif K

Zoho Recruit, CRM and Books into a new Supabase/Postgres backend, with ongoing backend work afterwards. The hard part is not the export, it is the schema: Zoho's modules map to a relational model only if someone decides what a candidate, a contact and a customer have in common. How I would run it: - Data model in Postgres designed from how you actually use the Zoho modules, with row-level security from day one - Export through the Zoho APIs, transformed and loaded with a validation report per module: counts, orphans, duplicates - Migration runnable repeatedly, so you can dry-run, check, and then cut over with fresh data - Supabase auth and policies set so the new backend is usable by your app immediately I run a multi-tenant platform on Supabase/Postgres with row-level security that consolidates 14 data sources, and I have Zoho CRM experience. One question: which Zoho modules and roughly how many records, and does the new app already exist or is it planned? Martin

ZOHO + SUPABASE Hi, Preserving candidate relationships, custom fields and attachments—and making migration reruns safe—will be central to this project. I represent Novatech, a development team. We’d begin by reviewing your existing Supabase architecture and Zoho modules, then map records and relationships into your current schema. Our approach would use reusable migration scripts with OAuth handling, pagination, rate-limit retries, stable source IDs and checkpointing. We’d first validate a representative dataset, then reconcile record counts, relationships and attachments before the final migration, with a documented cutover and rollback process. We can also discuss ongoing PostgreSQL, RLS, Edge Functions and integration support through Freelancer. Could you share approximate record counts, attachment volume and whether Zoho must remain active during migration? These will determine a realistic timeline. Happy to review the scope in a free consultation. Chris | Lead Developer | Novatech

ZOHO + SUPABASE I've built multiple Zoho Recruit and CRM integrations pulling via OAuth and REST APIs, then synced that data into PostgreSQL backends—so this is exactly my wheelhouse. I'll start by auditing your Zoho schema (Recruit modules, custom fields, relationships, attachments), then map it against your existing Supabase structure to avoid conflicts. The migration itself runs as a Node script hitting Zoho APIs in batches, transforming records into your PostgreSQL schema, validating referential integrity throughout. I'll handle attachment storage via Supabase Storage, set up RLS policies where needed, and leave you with a repeatable sync tool for any incremental pulls during transition. Data validation is baked in—I log mismatches so nothing silent fails. Once migration is complete and validated, I'm available for ongoing backend work: schema iterations, Edge Functions, Zoho sync maintenance, production support. I can outline exact approach and timeline after reviewing your current schema and Zoho environment. I'm available to start immediately. Thanks, Andrii.

From your brief, I understand you need to migrate Zoho Recruit, CRM, and Books data into Supabase/PostgreSQL, then support the backend as you scale. I'll audit your Zoho modules and custom fields, map them to your Supabase schema, build extraction scripts using the Zoho APIs, run and validate the migration, and document everything. If data needs to flow live during transition, I can also set up incremental sync. I've worked directly with REST APIs and backend data migrations, pulling records between systems and validating integrity at both ends. You'll get working migration scripts, validated data in Supabase, complete documentation, and a handoff for your team. Two revision rounds included. One scope question to get this right: how many records total across Recruit, CRM, and Books, and what's your target migration date? That'll help me scope phase one accurately. Jeremy
