Senior Full-Stack & AI Product Engineer — I take ambiguous problems from idea to shipped, production software. 14+ years across federal healthcare and regulated systems, now building production LLM applications end-to-end.
📍 Prosper, TX · ✉️ nkumarkallepalle@gmail.com · Open to Full-Time / C2C opportunities.
- AI / LLM products — multi-agent orchestration, RAG, deterministic structured outputs, and automated evaluation & quality gating on the Anthropic & OpenAI APIs.
- Full-stack systems — React 18 + TypeScript, .NET 8 / ASP.NET Core / C#, Python, SQL Server / PostgreSQL, REST & Minimal APIs, OAuth2 / OIDC.
- The whole thing — architecture → code → CI/CD → cloud (DigitalOcean / Azure, nginx / Linux) → 24/7 production support. I've shipped and operate live SaaS solo.
| Project | What it is |
|---|---|
| fivedaylaunch · case study | Live, multi-region AI website builder — a one-sentence-to-multi-page-site agent flow on the Claude API, with an 8-dimension quality scorer + CLI quality gate and a 1,935-site regression corpus. Full product: 24-page portal, mobile editor, Stripe / Razorpay billing, JWT + 2FA auth. |
| Clinical Dictation AI Pipeline | End-to-end medical speech-to-text: VAD → Whisper / faster-whisper ASR → clinical NLP (medspaCy), scored on Word Error Rate + clinical-concept accuracy, with a human-in-the-loop review editor (audio-synced transcript, drug/dose/negation flags, sign-off gate). |
| fdl-mcp-server | Model Context Protocol server that lets Claude / Cursor audit any website — practical AI tooling, no API key required. |
| Relvexa | Claude-powered agents automating medical-billing workflows, with Availity eligibility integration. |
| ai-learning | ML foundations from scratch in Python / NumPy — gradient descent, linear regression, and neural-network building blocks by hand. |
