Project details

You'll get a real AI feature built into your app — not a chatbot bolted on the side. I integrate Claude or OpenAI server-side (your key never touches the browser), return structured, validated outputs so your UI renders consistently every time, and handle the unglamorous parts: retries, rate limits, and errors. Every feature ships with an automated eval harness that tests the AI's output against a contract — so you get something dependable, not just a demo. I've shipped multiple live AI SaaS products, including one I built and sold, so I know how to take an AI feature from idea to production. Clear communication, clean handoff, and documentation included.

Existing App Rescue | Next.js, Python, AI Systems & Production Fixes
Atlanta, United States - 9:30 am local time
I take over existing applications that are unstable, half-finished, difficult to deploy, or hard for their owners to maintain. I find the real failure, fix it without rewriting everything, and leave the product in a state another developer can understand.

My core stack is TypeScript, React, Next.js, Node.js, Python, FastAPI, Supabase, and PostgreSQL. I work across the full path from data and APIs through backend logic, typed UI, testing, deployment, and handoff.

What I can help with:

• App rescue and stabilization - production bugs, failed deployments, broken data flows, authentication problems, API integrations, performance issues, and incomplete features.

• Existing-codebase takeover - map what is there, separate symptoms from root causes, preserve working behavior, and produce a prioritized repair plan before expanding scope.

• AI-generated code hardening - review and repair Next.js or Python products created with AI tools so they build reliably, handle errors, protect secrets, and remain maintainable.

• AI and LLM features - Claude and OpenAI integrations, RAG, multi-agent workflows, evaluations, metering, step limits, audit trails, and human approval gates.

• Clear delivery - focused changes, visible acceptance checks, plain-language status updates, and short documentation explaining what changed and how to maintain it.

Recent work includes designing and building a multi-tenant AI-agent platform with enforced tenant isolation, metered model calls, bounded execution, sandboxed generated code, and human approval before consequential actions. I have also shipped multiple live Next.js applications and taken over a client-owned Bubble product, including a compatibility-scoring rebuild delivered to production in approximately 48 hours. That engagement grew into ongoing feature and maintenance work.

I bring more than software experience to production debugging. Before moving fully into development, I spent over a decade in instrumentation and controls work, including the U.S. Air Force and Blue Origin. The medium changed; the habits did not: trace the system, verify the signal, control risk, document the fix.

Send me the current stack, the observed failure, and what "working" must look like. I will tell you plainly whether I am the right fit and what I would inspect first.

Steps for completing your project

After purchasing the project, send requirements so Frank can start the project.

Delivery time starts when Frank receives requirements from you.

Frank works on your project following the steps below.

Revisions may occur after the delivery date.

Scope confirmation

Lock down the feature's inputs, outputs, and model from your requirements.

Build the secure server-side AI endpoint

Create the API route that calls Claude or OpenAI on the server, keeping your key private. Design and test the prompt for reliable results.

Review the work, release payment, and leave feedback to Frank.
