What I build for you

◈  AI Products & Automation ▤  Apps & Platforms ∿  Quantitative Systems 🔒
Multi-tenant SaaS, agentic pipelines, and scraping systems that run themselves — from LLM integration to human-in-the-loop approval. Offline-first Flutter apps and fullstack monorepos, from empty repo to store-ready. Clean architecture, real test coverage. The deep end: HFT infrastructure, Kalman & Ornstein–Uhlenbeck estimation, empirical-Kelly risk governors, sub-ms pipelines.
