I will build your app using claude code and openai api
Usama R. Yousaf
About this gig
I use Claude Code and OpenAI to build, automate, and ship real software fast. Not a chatbot demo, a working product.
Senior full-stack + AI engineer (6+ yrs). Claude Code lets me write, test, and deploy multi-step features end-to-end instead of hand-coding line by line, so you get production apps in days, not weeks.
What I build:
- Full-stack apps built/shipped with Claude Code (frontend + backend + DB)
- OpenAI API integration into your product
- Custom AI agents & automations (Claude Code, MCP servers)
- Workflow automation (n8n + Claude/OpenAI)
- Bug fixes & feature adds to existing codebases
What sets me apart:
I'm a real engineer directing an agentic coding tool, not "prompting and hoping." Every delivery includes clean architecture, tests, docs, and deployment no half-finished, duct-taped features.
Stack: Python, Node.js, React, Next.js, FastAPI, Claude Code, OpenAI API, MCP, Postgres/MongoDB, AWS/Vercel.
Why work with me:
Senior engineer, not a reseller
Production-ready code, not prototypes
Full source code + ownership
Fast, clear communication
Message me your idea or codebase before ordering I'll recommend the right package.

FAQ
Do you use real Claude Code, not just ChatGPT prompts?
Yes. I run Anthropic's Claude Code directly from the terminal to write, test, and deploy multi-step features end-to-end, not copy-pasted chat responses. This gets you production-ready architecture, not disconnected snippets.
Can you integrate OpenAI's GPT-4o into my existing app?
Yes, I add OpenAI API integration to your existing frontend/backend (React, Next.js, Node, Python), including auth-aware calls, streaming, and cost/rate-limit handling.
What is an MCP server and do I need one?
MCP (Model Context Protocol) lets AI models like Claude connect to your tools/data securely. Most projects don't need one; I'll tell you honestly if yours does after reviewing your requirements.
Do I get the full source code?
Yes. Standard and Premium include full source code with complete ownership. Basic includes the working feature; full source is an available extra.
Can you fix an app that AI already built badly for me?
Yes, this is common. I review the existing codebase, fix broken database/auth/deploy issues, and clean up duct-taped AI-generated code into something maintainable.
