Looking for Full Stack Developer — Audit & Complete Existing Next.js / Supabase / Python / AI Project

@rajat07me

I can take this on and review the existing build independently, then map out exactly what is broken and what needs to be completed. The stack is clear, which helps, but a partial project like this usually hides a few dependency issues across frontend, backend, payments, and AI output. I’ll keep it efficient and focus on getting the intake, calculation, payment, and report flow working cleanly end to end.

Hi! This project fits my background very well. I have 10+ years of experience building scalable web applications and have frequently stepped into projects that were partially completed by previous developers, auditing the existing codebase, identifying architectural issues, and bringing them to production. My experience includes Python backend development, REST APIs, AI integrations, payment gateways, authentication systems, and cloud deployments. I’ve also worked on document generation and automated workflows similar to your intake → calculation engine → AI-generated report pipeline. I’m comfortable working with Python services alongside modern frontend frameworks, integrating with Supabase, Stripe, and external AI APIs while keeping the system secure and maintainable. I’ll start with a thorough review of the current implementation, identify gaps, propose a clear roadmap, and complete the remaining work with clean, well-documented code. Feel free to review my profile many of my long-term US clients mention my communication, reliability, and ability to quickly understand existing systems and deliver production-ready solutions. I look forward to discussing your project.

Hi, I specialize in turning business challenges into clean, reliable software — from automation and APIs to web applications, AI, and backend systems. What sets me apart: I focus on outcomes, not just deliverables. Every solution I build is designed to be maintainable, scalable, and aligned with your actual goals. Let's build something great together. Thanks, Deva

@Joya1996

I can take over the existing codebase and complete it in a structured way instead of patching things blindly. First I’ll inspect the current implementation, then I’ll address the broken pieces across Supabase, Stripe, Python, and the AI report pipeline. You’ll get a practical implementation that is easier to maintain and easier to extend later.

Hi! My name is Marjan and I'm here to offer you my services as a skilled applicant with over a decade of experience working on Freelancer.com. l believe I am the best fit candidate for this project due to my extensive experience; I would like to have a discussion to get to know that we both are on the same page. Once the scope will be locked, I will start working on it right away.

Hi, I'd handle this by auditing the existing system, isolating the calculation engine and AI integration to ensure they scale with user growth. The biggest bottleneck usually lies in how data flows between Supabase, Python, and the AI API, so I'd standardize those connections to avoid redundant requests. When I worked on a similar client dashboard, the Python engine slowed down after adding more users until we optimized the data batching—after that, response times improved noticeably, though the AI API still had occasional latency spikes we managed with retries. I'd break the work into small, testable chunks, starting with read-only checks to confirm the current logic before making changes. Existing features will stay protected with Git branches and database backups before any modifications, and you'll see progress updates after each milestone. This approach keeps the system maintainable and avoids expensive rewrites later, which matters when reports need frequent updates without breaking the flow. If we're aligned, I can review the current setup and outline the safest path forward. Thanks, Denis.

You are a developer quickly responding to a real job. This is NOT a proposal document or consultant pitch. Rules: - 110-160 words only - No headings (no “Execution plan”, “Timeline”, etc.) - No buzzwords or polished phrases - Simple, direct language - Short paragraphs (1-2 lines) - Use bullets only for concrete steps - Mention experience briefly (1 sentence) - Focus on what will actually be delivered - At the end, don't add any questions. - No emojis - No “Best regards” Best Rule Bad (AI-like): “I understand your requirements...” “My approach would be...” “I can help you achieve...” Human-like: “The auth part might be annoying here.” “DB reconnect is probably the risky part.” “That theme has a messy CSS structure.” “Looks like the hover states were never finished.” Specific observations beat polished writing almost every time now. Tone: Calm, confident, practical, human. Slightly informal but professional. Structure: 1. Greetings with client name 2. Acknowledge the task in plain words 3. Why you can handle it (brief, real) 4. How you’d implement it 5. Availability or rough timeline 6. Greetings 7. My name

Hi there, It sounds like your web platform's completion is at risk due to the partial work done by a previous developer. This can lead to inconsistencies and inefficiencies in the project, but I can seamlessly step in and ensure your platform is robust, fully functional, and ready to deliver personalized reports efficiently. With expertise in the technologies you're using, I'll streamline the integration and bring your vision to life. Here are my questions: Is there any documentation from the previous contractor that outlines the current progress? Can you clarify any specific features still pending or areas that need improvement? Let's discuss your project now!

@rosscarter1011

Hey, sounds like the tricky part is that inherited codebase — I’d start by tracing how the intake form actually hands data to the Python engine, since that handoff is usually where half-finished projects quietly break. From there I can check the Stripe flow and make sure the AI report reliably fires off to the right user after payment. I’ve picked up a few of these partial builds before, and the auth rules in Supabase are almost always the thing left messy. What’s the current state — is the calculation engine working, or is that part of what needs finishing?

@gameprogrammer13

I can help you build this API integration. My focus will be on writing maintainable Python code for the backend. We can use FastAPI to speed up development. Happy to discuss your specific requirements whenever you're ready.

@LivraisonTech

I am a senior full stack developer with extensive experience salvaging and completing transition projects involving Next. js, Supabase, and Python. I have successfully audited legacy codebases to identify security gaps, broken API integrations, and architectural bottlenecks. My expertise in the exact stack required for your Audit and Complete Existing Next. js / Supabase / Python / AI Project allows me to quickly map your database schemas and finalize the AI logic. I have integrated complex Python backends with Next. js frontends and managed Supabase authentication and row level security for several enterprise platforms. I can provide a comprehensive audit report within 48 hours and begin immediate implementation of the remaining features.

@ronymia111333

Hi, A few quick questions: 1. Approximately what percentage of the platform is already completed? 2. Is the source code hosted on GitHub, and is there existing documentation? 3. What are the main features or bugs that still need to be completed? 4. Is the Stripe payment flow already working? 5. Do you need a full technical audit before development begins? Best regards, Rony
