What I'm looking for

I seek senior technical leadership roles where I can build resilient, scalable cloud and AI platforms, drive institutional readiness, and mentor teams while enabling capital-efficient growth.

I am a senior engineering leader with 18+ years building infrastructure for hyper-scalers and high-growth ventures, blending hands-on systems architecture with strategic technical leadership.

At AWS I led large-scale systems for S3 Index and S3 Console, optimizing performance and migrations; at startups I’ve created defensible technology moats that supported significant funding events.

I found and lead engineering teams and studios, designing serverless, event-driven microservices and AI-powered products using TypeScript, Node.js, LangChain, Qdrant, and Postgres, while deploying observability and governance with LangFuse, SigNoz and PostHog.

I prioritize institutional readiness—security, compliance, and capital-efficient roadmaps—to help companies scale globally, withstand due diligence, and deliver reliable, mission-critical services.
