About

A short version.

Full-stack engineer with two years of applied experience pairing production React/TypeScript front-ends with Python AI services in real shipping products. I write code that other people maintain, document the workflows so non-engineers can run them, and use AI tooling daily as part of the work rather than as a side project.

Day-to-day I work in Next.js 15, React 19, TypeScript and Tailwind on the front; FastAPI, Node.js, Postgres + pgvector, Redis and BullMQ on the back; and OpenAI, Gemini, LangChain and MCP servers when the product needs intelligence. Auth with Supabase (Google OAuth, magic link, PKCE), shipping on Vercel and GCP Cloud Run. Recent builds include MedReviewAI for grounded medical literature review and ScholarAI for in-browser research-paper analysis.

I default to written specifications before code, runbooks alongside features, and reviews that move the codebase forward — easier to work in than I found it.

Experience

Where I've shipped.

  1. Apr 2026 – Present Remote, UK

    Full-Stack / AI Engineer Intern · Meta Solution Technologies

    • Building an AI-guided admissions platform on Next.js 15 + React 19 + TypeScript + Tailwind, talking to a Python LLM service over a typed REST API. Chat-style guidance flow runs on OpenAI with structured outputs and a Postgres + pgvector knowledge store.
    • Wrote auth end-to-end (Google OAuth, magic-link, PKCE) on Supabase, plus a BullMQ + Redis job queue that drives async generation, document checks and email triggers.
    • Shipped 10-language i18n and a dual-theme CSS layer so non-engineering teammates can roll out copy and translation updates without involving me. Use Claude Code daily for refactors and review.

    Software Engineer Intern · Recruit Pilot — Chris Hines (Recruitment-Tech)

    • Built React + TypeScript UI features against a REST API for a recruitment-tech product. Took part in code review and weekly sprint cadence alongside more senior engineers.

  3. May 2024 – Jan 2026 Remote

    AI Engineer (Freelance) · Self-Employed

    • Shipped 20+ AI-powered apps for paying clients across SaaS, e-commerce and consulting — most had a React or Next.js front end on top of a Python service running Claude or OpenAI APIs with structured outputs and a RAG retrieval layer.
    • Built five longer-running AI agents (lead-gen, customer support, data processing). Each project ended with a README, a short walkthrough video and a written hand-off doc so the client team could run the workflow without me.

    Front-End Developer Intern · Unified Mentor — EdTech / Mentoring Platform

    • Built React UI features on a learner-facing app serving thousands of users — components for lessons, progression and learner dashboards, integrated against a REST API. Code review, agile delivery, shared QA cycles.

MCP Marketplace — registry of 800+ Model Context Protocol servers
MCP · Registry

MCP Marketplace

A searchable registry of Model Context Protocol servers — the emerging plug-in standard for agent toolchains. Pulls from Glama and the official MCP repository on a daily schedule, normalises tool schemas, and renders one-line install snippets for Claude Desktop, Cursor and Claude Code. Built on Next.js 15 RSC with MIT-licensed source.

NEXUS Research Paper · DOI 10.5281/zenodo.20059414

Authored an open-access preprint on closing the residual ~50 ms latency gap between cloud gaming and local wired console play. The system combines on-controller transformer inference, a direct 6 GHz Wi-Fi link with OFDMA priority scheduling, and a cloud-side speculative renderer with bounded mispredict recovery. Indexed on Zenodo with a Crossref DOI and mirrored on ResearchGate.
