Principal Software Engineer · Founder · New York
I build the parts no one owns yet.
I’m an engineer and founder with 8+ years building distributed systems, developer infrastructure, and production AI — across AWS, Microsoft, and two startups I co-founded. I gravitate toward ambiguous, high-ownership problems and carry them from an empty repo to something running in production.
Right now that’s DeFi protocols and multi-agent AI for financial research — smart contracts, backend services, and agent pipelines included.
Tech lead for ECR Cross-Region Replication — 20+ regions, 10,000+ customers, 200M+ image pushes a month.
Web3 wealth management — private client portfolios averaging 15–20% yield. I own product design, infra, portfolio rebalancing, risk management, DeFi protocol analysis, and trading strategy optimization (arbitrage).
Built an LLM research platform for buy-side analysts from empty repo to product — infra included.
Tech-led a 4-engineer team on correctness-critical commission systems.
Optimized the HDX remote-display path and its performance telemetry. Promoted to Senior.
Shipped backend features and internal APIs (C# / .NET) on Azure at cloud scale.

SmileSyncSystemAI voice agents plus CRM automation for clinics. A low-latency streaming stack (ASR→LLM→TTS) answers calls, qualifies patients, and books appointments — with multi-channel follow-up and no manual data entry.
A self-hosted Solana node fleet ingesting the full Geyser firehose. A new-pool sniper, same-block copy-trader, and atomic cross-DEX arbitrage — sub-400ms detect-to-land via Jito bundles.
Mock interviews and prep for senior software roles — backed by 10 years of hands-on engineering at Big Tech and startups.
I’ve built e-commerce brands and run the ads myself, and multiple sites of my own rank on Google’s first page — technical SEO, content, and AI search.
I’ve shipped many AI products — roadmap, product–market fit, and positioning advice grounded in real builds.
Open to conversations — hiring, investing, or comparing notes.
