AI Full-Stack Developer Needed – Build a Global AI SaaS Platform for Businesses I am looking for an experienced AI Full-Stack Developer (or a small development team) to build an innovative AI-powered SaaS platform designed for businesses and professionals. This is not a one-time project. My goal is to build a scalable global AI platform offering multiple AI-powered business services. The first module will focus on financial reporting and annual financial statement preparation for companies and accountants. Project Overview The first version of the platform should be able to: * Import accounting data from Excel, CSV, PDF files, and accounting software. * Analyze financial and accounting data using Artificial Intelligence. * Automatically generate annual financial statements. * Generate Notes to the Financial Statements and Management Reports using AI. * Detect inconsistencies, anomalies, and potential accounting issues. * Calculate financial ratios and business performance indicators. * Produce professional reports in PDF and Word formats. * Export the complete financial statements in PDF format. * Export financial statements in XBRL format, compliant with applicable regulatory and filing standards. * Integrate with Large Language Models (OpenAI, Claude, Gemini, or similar). * Be designed as a modular platform that can easily support additional AI services in the future. Required Skills The ideal candidate should have experience with: * AI application development * Large Language Models (LLMs) * Python * FastAPI or Django * React / [login to view URL] / Vue.js * PostgreSQL * REST APIs * Authentication and user management * Docker * AWS, Azure, or Google Cloud Experience developing accounting, ERP, financial, business management software, or XBRL reporting solutions is a strong advantage. What I’m Looking For I am not simply looking for a freelancer. I am looking for a long-term technical partner to help build an ambitious international AI company. The financial statement module is only the first product. The long-term vision is to develop a complete AI ecosystem offering intelligent services for businesses, accountants, lawyers, consultants, and other professionals. Please Include in Your Proposal * A brief introduction about yourself or your team. * Your experience with AI projects. * Examples of similar SaaS or AI applications you have developed. * The technologies you recommend. * Estimated development timeline. * Cost estimate for the MVP. * Suggestions to improve the project. * Your availability for a long-term collaboration. If you have experience building AI SaaS products, accounting software, ERP systems, or XBRL reporting solutions, I would be very interested in reviewing your portfolio.

Hi — Elias here from Miami. Building a global AI SaaS platform presents an exciting opportunity to enhance business operations. The core goal is to create a reliable, scalable solution that efficiently automates tasks for users. What usually matters most here is ensuring that the architecture supports future growth and can seamlessly handle increased workloads. A common issue in systems like this is managing complex integrations while maintaining a smooth user experience. The tricky part is usually ensuring the AI components work seamlessly with existing business workflows. My approach would involve establishing a modular architecture, allowing for easy updates and feature additions. This focuses on stability and maintainability, ensuring the platform can adapt to evolving user needs. Having worked on similar AI-driven platforms, I understand the importance of robust backend systems and user-friendly interfaces. A few questions to better understand the scope: Q1 – What specific user roles and permissions do you envision for the platform? Q2 – Are there particular integrations you anticipate needing with existing systems? Q3 – What are your scaling expectations as the platform grows? Happy to go through the details and suggest the best technical approach. Looking forward to hearing from you.

Hello!, I am a US-based senior software engineer(frontend, backend, ecommerce, etc) and I read your project description carefully. You’re building a global AI SaaS platform for businesses, and that needs to be more than just “AI added on top” it has to be reliable, useful, and scalable from the start. I’ve got about 15 years of experience with PHP, Python, FastAPI, full stack development, AI integrations, and SaaS platforms. My focus is always practical: clean architecture, smooth UX, stable APIs, and a build that can grow without becoming hard to maintain. My approach would be: 1. Clarify the core business tasks and user flow 2. Define the AI logic and backend structure 3. Build the frontend and API in parallel 4. Test, refine, and prepare for launch Could you please clarify the following questions to help me better understand the project? 1. What are the first 2 or 3 tasks you want the AI to handle? 2. Do you already have branding/UI direction, or should I help shape that too? 3. Is this web app only for now, or do you want room for future admin/API expansion? I’ve built AI dashboard tools, workflow automation platforms, a Python/FastAPI assistant, and SaaS reporting systems for small business teams. If you want someone who actually reads the details and can turn the idea into a solid product, I’d be glad to chat. James Zappi

Hello, This project needs a strong foundation because financial reporting demands accuracy before AI. I would keep the platform modular with FastAPI, React, PostgreSQL, Docker, and LLM integrations so future business modules can be added without rebuilding the core. One important question: which accounting standards should the first release support—IFRS, GAAP, or country-specific rules? That decision affects the data model, report generation, and XBRL mapping. I would also include validation before AI-generated reports to reduce errors and improve trust. Let's build an AI platform where accountants review insights, not spreadsheets... and Excel finally gets a well-earned vacation. Best regards, Dev S.

Your XBRL export requirement will fail regulatory audits if the taxonomy mapping isn't validated against jurisdiction-specific schemas before file generation. Most developers hardcode XBRL without understanding IFRS vs GAAP dimensional hierarchies, which creates compliance liability. Quick questions - are you targeting EU ESEF filings or SEC EDGAR submissions, since the validation rules differ completely? And what's your data volume expectation - 100 companies processing monthly closes or 10,000 SMBs running annual statements? Here is the architectural approach: - PYTHON + FASTAPI: Build async document processing pipeline using LangChain for multi-format ingestion (Excel/CSV/PDF) with OCR fallback, then structure extraction via GPT-4 with validation layers before financial calculation engine. - XBRL COMPLIANCE: Implement Arelle-based taxonomy validator integrated with jurisdiction-specific schema libraries, auto-mapping GL accounts to XBRL concepts using semantic similarity models, then pre-submission validation against official test suites. - POSTGRESQL + VECTOR DB: Design normalized schema for GL data with temporal versioning, add pgvector extension for semantic search across historical financials, partition tables by fiscal year for query performance at scale. I've built two fintech platforms processing $40M+ in transactions monthly, including SEC-compliant reporting systems. Let's schedule a 20-minute technical call to map your regulatory requirements before architecture decisions lock you into the wrong compliance framework.

Hey, the XBRL export for financial statements immediately caught my eye – that's a critical detail for regulatory compliance. I'd approach that by mapping your data to the appropriate taxonomies, likely using a dedicated Python library for XBRL generation. The real challenge will be standardizing the diverse input data from Excel, PDF, and various accounting software before the AI can reliably process it. What specific accounting software integrations are you prioritizing first?

XBRL export is where most financial AI platforms quietly fail. Tagging financial statements correctly for regulatory filing isn't just formatting — taxonomy mapping, context definitions, and jurisdiction-specific rules mean a small error makes the entire filing invalid. That part needs careful design from the start, not bolted on at the end. The AI layer for anomaly detection and notes generation is more tractable than it sounds if the data pipeline is clean. Most of the real work is structured extraction from Excel, CSV, and especially PDF accounting exports, since those vary wildly between software vendors. Which jurisdiction's XBRL taxonomy are you targeting first — ESMA for Italian companies, or are you building for multiple regulatory frameworks from the outset?
