I design and ship agentic workflows, RAG systems, and real-time interfaces where model behavior, product UX, and backend reliability have to agree.

A mix of open-source projects and private product systems:
-
📬 Rails Mailer Sandbox · Public
A Mailtrap-inspired local email inbox for Rails, packaged as a Ruby gem with persistent MIME storage, safe previews, search, and attachments. -
🎨 Jamboard · Public
A collaborative AI-powered whiteboard built with React, TypeScript, Canvas, and Yjs for real-time multi-user editing. -
🎙️ Codexia Live · Private repository
A real-time technical interview coach combining voice, live code analysis, stress signals, progressive hints, and inspectable AI interventions. -
🛏️ The Beddo AI-CRM · Private repository
An agentic CRM inbox that extracts lead information while exposing tool calls and activity telemetry for human oversight. -
🎬 AIClipper.video · Private repository
A serverless pipeline that turns long-form videos into vertical clips using transcription, AI-assisted segment selection, and automated media processing.
📡 Signal → 📚 Context → 🧭 Policy → 🔧 Tool call → 💬 Feedback → 📈 Outcome
- 📚 Context — RAG, memory, retrieval, and traceable sources
- 🧭 Policy — route, reason, ask, answer, call a tool, or wait
- 🔎 Observation — traces, evaluations, review states, latency, and cost controls
The useful part is not an impressive internal chain of thought. It is a reliable result that people can understand, inspect, and act on.
