I build AI features that real users touch: voice AI agents, LLM-powered apps, and AI integrations inside your web app or SaaS. Full-stack, so I ship the whole thing, not just the model call. Recent work on Upwork: • Real-time AI voice chat: Django + React + LiveKit, with live speech in and out (5★) • AI speech & communication coaching platform, built over 4 months (5★) • Micro-frontend migration from Module Federation to single-spa for a finance app (5★) • Backend rental system for a national e-commerce brand's $50M platform What I can build for you: • AI agents & assistants: tool-calling agents, RAG over your docs, chat inside your product • Voice AI: phone/web voice agents, real-time conversation (LiveKit, OpenAI Realtime, Twilio) • AI integration: add OpenAI/Claude/Gemini features to an existing React, Next.js, Node or Python app • Full-stack SaaS: React/Next.js frontends, Node/Python (Django, FastAPI) backends, Postgres, AWS How I work: 1. You explain the business goal; I reply with a short plan, cost and timeline. 2. I share progress every few days with working demos, not just status updates. 3. You get clean, documented code you fully own. Send me your idea or job post and I'll tell you within a few hours how I'd build it.
