What I'm looking for

I'm seeking senior engineering roles building production-grade 3D/ML-enabled web and mobile products, focused on performance, scalable infrastructure, and collaborative teams where I can mentor engineers.

I am a senior software engineer focused on building high-performance web and mobile experiences, with deep expertise in 3D graphics and ML-enabled products.

At Luma AI I led development of interactive 3D viewers using React, Three.js, and WebGL, achieving smooth 60 FPS rendering and reducing mobile load times by 30%. I also architected microservices and asynchronous media pipelines in Python and Node.js that processed thousands of 3D captures daily while maintaining 99.9% content delivery uptime.

Previously at Linear I delivered an offline-capable Electron tracker, launched a 30-component design system, and implemented real-time sync with GraphQL subscriptions under 100ms; at Robinhood I built onboarding/KYC flows and real-time trading dashboards that supported millions of users.

I enjoy solving performance and scalability challenges, integrating ML models into production, and mentoring engineers. I emphasize testing, CI/CD, clean architecture, and measurable product outcomes that improve reliability and user experience.
