Rai T.

I help founders and business owners turn AI ideas into working products, fast and reliably. AI agents, RAG chatbots and voice AI (TTS, STT) are what I build most.
1,800+ hours on Upwork, 100% Job Success, Top Rated Plus.

What I build:

• AI agents that connect to your tools and take real actions (LangGraph, MCP)
• RAG chatbots that answer from your own documents, with sources
• Voice AI: speech-to-text, text-to-speech and voice agents
• AI features inside your existing product
• Web and mobile apps around them

What I've shipped:

• Finviro: AI personal finance app, live on the App Store and Google Play with 300+ users
• VOX: on-device text-to-speech iPhone app, live on the App Store
• Box Box Builders: agentic construction management platform
• Incucount: AI bacterial colony counter, published on the Microsoft Store
• Axi: AI nurse for UK health clinics
  Other than that, I've also made patient-facing medical chatbot, self-hosted Whisper transcription, and lead engineer on an LLM and MCP platform for a leading AI company.

Work with me if:

• You want to build an AI product or app
• You have a business problem to solve with AI (LLMs, voice AI, computer vision)
• You're a startup that needs to ship without hiring a full team. I cover design, backend, AI, web and mobile, end to end.

How I work:
Short scoping call, written plan with milestones, working prototype on your real data, feedback, revisions, testing, release. You get a written update at the end of every working day. I overlap with US Eastern mornings and full European hours.

How we can engage:

• Fixed-scope project
• Hourly
• Monthly support retainer.

Most clients start with an MVP, move to hourly, then to a monthly retainer.

Stack: Python, FastAPI, Next.js, React Native, PostgreSQL, AWS, LangGraph, PyTorch.
