What I deliver: ▸ AI & LLM systems — RAG pipelines with source citations, autonomous agents with tool use and human-escalation logic, document Q&A over your knowledge base. Built with LangChain/LangGraph, OpenAI & Claude APIs, and vector databases (Chroma, pgvector). My open-source work includes a production-ready customer support RAG platform and a real-estate AI agent that qualifies live leads over WhatsApp. ▸ Full-stack web apps — React, Next.js, and TypeScript frontends on Python (FastAPI/Django) or Node.js backends, with PostgreSQL/Supabase, authentication, role-based access, and REST APIs. Shipped with tests, Docker, and documentation — not notebook code. ▸ Mobile apps — I built the two Flutter apps (rider + driver) behind Links 592, a ride-hailing platform in Guyana: realtime geo-matching, live trip tracking, payments, and a Next.js operations portal, all on a shared Supabase/PostgreSQL backend. ▸ Computer vision — YOLOv8 detection systems on live camera feeds with automated SMS/email alerting. How I work: I ship in small, reviewable increments so you see working software early. I work from written specs without hand-holding, communicate proactively in writing, and I'm honest about scope — if something will cost more or take longer than you expect, you'll hear it from me before we start, not midway. Based in Guyana (GMT-4) — same clock as US Eastern, strong overlap with UK/EU afternoons. Available 38 hrs/week for both project work and long-term engagements.
