Cover image for Built 130+ engineering calculators spanning
Built 130+ engineering calculators spanning 13 disciplines — process, pipeline, mechanical, civil, electrical, instrumentation, safety, operations, rotating equipment, tanks, utility, piping, and general. Originally deployed as an internal tool with a hosted dashboard for a midstream oil and gas operator. Now rebuilt as interactive web calculators in Catalyst OS, running client-side with React and TypeScript. Each calculator features validated inputs with unit handling, real-time computation, results export, and responsive design. Includes financial tools (debt payoff, FIRE number), health tools (TDEE, sleep debt, burnout risk), and engineering tools (pipe flow, heat transfer). Tech: React 19, TypeScript, Tailwind CSS. No backend calls — all math runs locally in the browser.

Cover image for Built an AI coaching system
Built an AI coaching system called The Mirror — a context-aware assistant that learns about each user and delivers personalized insights across 5 life dimensions. Features 5 chat modes (Chat, Guided, Deep, Research, Insight), each with specialized prompts and behavior. Guided Intake builds a user profile through conversation, tracking understanding across key life areas. All responses grounded in a RAG knowledge base via pgvector semantic search. The research pipeline generates 6 evidence-based documents daily via Claude and ingests peer-reviewed papers from PubMed weekly — automatically chunked, embedded, and stored for retrieval. Tech: Next.js 15, Claude API, Supabase (pgvector + RLS), OpenAI embeddings, n8n. Shipped as a core feature of Catalyst OS with Supabase Auth and Stripe-gated Pro access.
