My personal website, rebuilt from the ground up as an immersive, scroll-scrubbed journey through my work. As the visitor scrolls, a pre-rendered camera flies through a connected set of isometric scenes, each introducing a facet of what I do: AI-augmented full-stack engineering, the SaaS products and games I design and ship solo, and the writing and conference talks I have shared since 2011.

I handled everything end-to-end: art direction and AI-generated scene imagery, the scroll engine, responsive, mobile-first layouts, dark mode, and SEO, with server-rendered fallback content and structured data for crawlers and no-JS visitors.

EVPick compares 1,700 EVs from 65 brands on real specs, and finds the right one for you.

Retrieval is hybrid: pgvector similarity fused with Postgres full-text search via reciprocal rank fusion, so paraphrase and exact terminology both resolve, across languages. An agent runs tool-calling against the corpus and renders live comparison tables in the UI rather than answering from model memory.

THUMB & PYLON is a tower defense game for iOS and Android, built as one React Native and TypeScript codebase. The board is drawn rather than illustrated: every tower, enemy, road, and effect is rendered as geometry at runtime with Skia, so the app ships only three image assets in total and looks identical on both platforms. I built it end-to-end. The rules live in a deterministic simulation shared by the client and the server, which is what makes the leaderboards trustworthy - every submitted run is replayed inside a Supabase Edge Function before it is allowed to rank. Hence, a score has to be reachable under the same rules everyone else played under. Campaign levels are generated from a difficulty ramp rather than placed by hand, with tests asserting the rules hold: each wave heavier than the last, a boss on every lane, and every level clearable by the build it teaches. Release is automated with Fastlane, so one command produces a signed Android bundle for Play internal testing and another a signed iOS build for TestFlight.

A full-stack web app that generates customizable revenue and MRR chart images. I designed and built the entire product solo: a Next.js 16 (App Router, TypeScript, Tailwind CSS) front end; a Firebase back end (Auth, Firestore, Storage); serverless Cloud Functions using Puppeteer for server-side image generation; and Stripe-powered credit packs for monetization.
