Hello there If you are interested in this proposal, I’d be happy to discuss the next steps and project process with you. I am interested in your project and can present my previous work as references. I can take over the existing Convex/React/TypeScript SaaS without rebuilding completed functionality. I’ll first audit the current codebase, Convex backend, database, authentication, permissions, integrations, and remaining issues, then complete and stabilize the platform based on the existing architecture. I can also handle the migration from Hercules, preserve application data and assets, configure your company-owned GitHub repository, staging and production environments, CI/CD with GitHub Actions, and independent cloud hosting with full ownership remaining on your side. The key priorities will be preserving existing functionality, resolving backend/frontend issues, ensuring reliable Convex synchronization, and creating a deployment workflow your team can maintain independently. I’ll provide clear progress updates, document important technical decisions, and test the complete system before production launch. Portfolio: https://www.freelancer.com/u/Hammadhassan21 Could you provide access to the current codebase and Convex project so I can audit what is already complete and identify the remaining work before proposing milestones? Best regards, Hammad Hassan

The safest way to complete this platform is to first take control of the existing code, data and deployment path before changing working functionality. I would begin by auditing the Hercules project, React/TypeScript codebase, Convex schema/functions, authentication, integrations and current production environment. I’ll separate what is complete from what is partially implemented or platform-dependent, then move the code into your company-owned GitHub workflow without unnecessarily rebuilding working modules. For Convex, I would keep the initial migration low-risk: company-owned Convex deployments for development/staging/production plus independent frontend hosting and GitHub CI/CD. If complete backend infrastructure ownership is required later, Convex can also be self-hosted. The first phase includes architecture/code audit, Hercules dependency review, data/export verification, GitHub setup, Convex review, deployment plan, priority bug list and a documented completion roadmap. I can then continue directly into the implementation phase based on the verified remaining scope, with regular progress updates and no architectural rebuilds without approval.

hello, The first thing to settle is what Hercules actually lets you export, since AI app builders often wire in their own auth, hosting, or managed Convex project, and the migration plan depends on whether you get clean source plus direct access to the Convex deployment. So I'd audit that before anything else, then move the code into your GitHub, stand up your own Convex project, and migrate the data with auth reconnected, so no user loses their account or history in the switch. Once it's independent, I'd set up main and development branches with CI/CD, Vercel or similar for the React front end and Convex's own deploy for the backend, with separate staging and production. Then I'd work through the unfinished CRM features and bugs on staging, preserving the existing UI, since dispatch software has to stay live and reliable while it evolves. Can you export the full source from Hercules today, and do you have admin access to the Convex dashboard? And is the mobile app part of this codebase, or separate? have a nice day.

Hey there! I see you’re looking for a Senior Convex/React Developer to wrap up your SaaS platform and handle the migration from Hercules. That’s a crucial step to ensure your CRM application is not just functional but also scalable and efficient. With over 10 years in full-stack and mobile app development, I’ve tackled similar projects, ensuring a smooth transition and optimizing performance. My experience with React.js and React Native aligns perfectly with your needs, and I’m well-versed in managing both frontend and backend challenges. Plus, I’m comfortable working within your budget and can adapt to your team’s workflow. I’d love to chat more about your specific requirements and any challenges you foresee during the migration. Looking forward to hearing from you! Clarification Questions: 1. What specific features or functionalities do you need prioritized in the CRM application? 2. Are there any existing data or user workflows from Hercules that we need to consider during the migration? 3. What’s your current tech stack, and are there any integrations or APIs that need to be maintained or modified?

@rajat07me

The key here is not rebuilding your SaaS, but taking over an already-developed Convex/React codebase safely, finishing what is incomplete, and removing the Hercules dependency without breaking working parts. Projects like this usually fail when a developer starts “improving” architecture before fully mapping data flow, auth, deployments, and environment dependencies, so I’d begin with a structured audit and then complete the remaining work in controlled phases. I’ve worked on existing web apps where the real job was understanding inherited logic, fixing weak backend/frontend links, stabilizing deployment, and making the system independently maintainable afterward. Your need for company-owned GitHub workflow, staging/production separation, infrastructure ownership, and documented handoff is exactly the right approach for a SaaS product that needs to keep evolving. A few points I’d want to confirm first: - Is the mobile app a separate React Native codebase, or part of the same web stack/responsive app flow? - Do you already have access to the full Hercules source export and Convex project, or would that extraction be part of the assignment? - Which hosting direction are you leaning toward right now: Vercel + Convex, AWS, or Docker-based deployment on your own server?

Hey there, You need someone to take an already developed Convex and React SaaS platform, understand what is complete versus unfinished, resolve the remaining issues, and migrate it away from Hercules without unnecessarily rebuilding working components. I would begin with a structured codebase and infrastructure audit, then address Convex functionality, authentication, permissions, integrations and outstanding bugs. I would move the project into your company owned GitHub repository, establish staging and production environments with CI/CD, and configure independent hosting while keeping all source code, infrastructure and credentials under your ownership. Can you provide temporary access to the current Hercules project and repository so I can assess the migration dependencies and give you a realistic completion estimate? Looking forward to working together. My portfolio and client reviews, https://www.freelancer.com/u/zainalitariq245 Best regards, Zain Tariq.

Hi, I’ve reviewed your project and can assist in completing your SaaS platform while migrating it away from Hercules.app. Depending on the complexity of the remaining features and issues, I estimate around 4-6 weeks to finalize everything. Could you clarify which hosting provider you’re considering, or if you’d like recommendations? Also, are there specific integrations or functionalities that are a priority for immediate completion? To tackle your needs, I’d first audit the existing codebase to identify the outstanding issues and incomplete features. Then, I’d focus on the migration process, ensuring a seamless transition while maintaining current functionality, followed by setting up the GitHub repository and deployment pipeline to streamline future updates. With experience in Convex, React, and database migrations, I'm well-prepared to bring this project to completion. Happy to discuss the current setup and take it from there. Best regards, Mohammad

@installerpoint

Hello, I’m interested in helping you complete and independently deploy your existing SaaS platform. I understand that the application is already substantially developed, so my approach would be to audit, understand, stabilize, and complete the existing architecture rather than unnecessarily rebuilding working components. I’ll also provide technical documentation covering the architecture, deployment process, environment configuration, and ongoing development workflow. I’m comfortable working with React, TypeScript, full-stack applications, APIs, databases, Git/GitHub workflows, mobile applications, and cloud deployment. I understand the importance of company ownership here: the source code, GitHub repository, database, hosting, infrastructure, and credentials should remain under your company's control. I’d be happy to start by auditing the existing application and producing a clear list of what is complete, what needs fixing, and what remains before production launch. Thank you. Best regards ADEEL

Having built robust cloud-based management tools, I ensure clean, scalable code, seamless GitHub workflows, and high-performance mobile-ready architecture. When are you looking to kick off the final deployment phase? Best regards, Giáp Văn Hưng

@inventivedesigne

Hi! This is exactly the kind of technical completion and migration project I handle well, stepping into an existing codebase, understanding what's already built, and bringing it across the finish line without unnecessary rebuilding. I'll audit your current Convex and React architecture, complete the outstanding CRM and backend functionality, resolve existing issues, migrate everything cleanly away from Hercules to your chosen independent infrastructure, configure your company-owned GitHub repository with proper CI/CD pipelines, and hand over full ownership of source code, database, and deployment credentials with clear documentation. Quick question: do you currently have access to export the full source code from Hercules, or is part of the migration challenge extracting the codebase from their platform first? I've worked with Convex, React, TypeScript, and GitHub-based CI/CD deployments on SaaS platforms, and I understand the discipline required when completing existing systems, communicate before changing architecture, preserve what works, and fix what does not. Ready to review your existing codebase and give you a clear completion plan! Hafiz S.

@longngoc2307

Perfect Match "EXISTING CONVEX SAAS COMPLETION" — you need the current CRM finished, stabilized, and moved away from Hercules without rebuilding working parts. I’d audit the existing React/TypeScript and Convex architecture first, map the remaining gaps, then fix them in place. I’d also move the source and infrastructure into your company-owned GitHub, with separate staging/production environments and CI/CD so future releases are fully under your control. Can you provide the current Hercules export/repository and Convex project access so I can assess what is already complete before changing the architecture? Looking forward to work with you

@KasjanovaEste

Hi im Fernando Garcia from Mexico I read the brief and understand you are not looking for a rebuild. The main goal is to take the existing Convex and React SaaS, preserve what already works, remove Hercules dependencies, and leave your company with full GitHub and hosting control I would first review the existing React, TypeScript and Convex architecture, then map incomplete features and Hercules dependencies before changing anything. From there I can handle the migration, GitHub workflow, staging and production setup, and final testing without replacing working parts Step 1: Audit the codebase and infrastructure in 2 to 3 days Step 2: Fix remaining CRM, Convex and integration issues based on the audit Step 3: Migrate, configure CI/CD and complete production testing I have build SaaS platforms and focus on completing existing systems carefully instead of rebuilding working components Which part of the current platform is causing the most business impact today, so I can prioritize it during the audit? For the migration, would you prefer AWS, DigitalOcean or Vercel as the primary application host, and what makes that option fit your operation? Should the first milestone end with an audit and migration plan, or should it include the first production fixes as well? Happy to plan the best way with you thanks

@manh2906

Hi There - Manh here "CONVEX REACT SAAS COMPLETION & MIGRATION" — you need the existing dispatch platform finished and moved away from Hercules without rebuilding working components. I would audit the current React/TypeScript and Convex architecture first, map incomplete features and dependencies, then fix the remaining issues against the existing UI and business logic. For the migration, I’d move source, data, configuration and assets into company-owned infrastructure, then establish GitHub-based staging, production and CI/CD so future deployments remain independent. I’d verify authentication, permissions, database sync, integrations and mobile workflows before production launch. Can you provide the current GitHub/source export and confirm which hosting provider you want to use after leaving Hercules? Looking forward to working with you.
