"Gutta cavat lapidem, non vi, sed saepe cadendo."
The drop carves the stone not by force, but by falling often.

🧭 About

Software engineer, systems architect, and CTO. After a decade in quantitative finance, I now lead engineering at the intersection of high-performance systems, AI, and Web3. Obsessed with correctness, latency, and shipping things that hold up under real load, from trading engines to distributed AI infrastructure.

⚑ What I Do

  • Systems & Architecture β€” high-performance distributed systems, real-time processing, and resilient infrastructure.
  • Quantitative Trading β€” 10+ years in electronic markets: HFT, market making, and automated options & equities strategies.
  • AI & Data Science β€” embeddings, vector search, semantic retrieval, and real-time streaming pipelines.
  • Cloud & DevOps β€” Kubernetes, GPU optimization, and scalable audio/video processing.
  • Web3 β€” building on Solana, Ethereum, and Bitcoin.
  • Security β€” pentesting and secure-by-design engineering.
