Summary

I have spent more than a decade at Iconosquare, moving through senior engineering, backend leadership, and development management into a Principal Engineer role. I work across architecture, software design, technical direction, and mentoring for scalable backend and frontend systems.

That continuity gives me both the long view of an evolving product and the hands-on context needed to make pragmatic technical decisions.

Projects

Newest first. The experiments hub has covers, write-ups, and links for each.

• Deus Ex in the Browser (2026) — The original 2000 Deus Ex running in a browser tab from a local install: a JavaScript reader for the Unreal Engine 1 packages, a Rust interpreter compiled to WebAssembly, and three.js on WebGL2. The game’s own bytecode runs on a rebuilt engine, and every translated piece is checked against the original: its DLLs in a CPU emulator, and frames and tick traces from the running game. Built by directing AI agents under that evidence rule: 995 commits and about 31,000 lines of Rust in five weeks.
• jeromem.dev (2026) — This site: a Rust static-site generator with live gpui islands compiled to WebAssembly, art generated at build time, and a benchmarked performance pass that brought first paint about 40% sooner and opens pages in roughly half the time.
• Raym (2025) — Interactive terrain generation and sculpting with Marching Cubes, in C and Raylib, also compiled to WebAssembly.
• Earlier: Monkey interpreter in Rust (2017) · 3D Chip8 emulator in C++ (2017) · Game of Life in Haskell (2016) · Flappy Bird in Haskell (2015) · Fake Images Please (2012), a placeholder-image service.
