Full-stack engineer at DULTRA building a live AI sales copilot; previously grew fossil.gg to 160,000+ players.
LithuaniaWhat I'm looking for
At DULTRA, I own engineering end to end and built a listen-only live call copilot that surfaces battlecards during sales calls, alongside a voice role-play simulator. I also built its document ingestion and vector search knowledge layer.
From 2021 to 2026, I built and ran fossil.gg as its sole engineer, growing it from a Discord economy bot into a platform serving 160,000+ players and recording 70M+ operations. I re-architected it as a multi-tenant web SaaS and merged 58,000 player accounts from a client's legacy system without downtime.
I also built ccautopsy, an open-source CLI that explains why Claude Code rebuilds its prompt cache, and contributed remix-authjs, an Auth.js adapter for Remix and React Router. I’m now looking for a full-time role; fossil.gg is stable and doesn’t need me day to day.
