What I'm looking for

I'm looking to lead end-to-end development of AI-powered SaaS and cloud-native products, building scalable distributed systems and high-performance user experiences while mentoring engineers.

At Scale AI, I lead AI-powered enterprise platforms and cloud-native services for large-scale LLM applications. I built RAG search and knowledge-discovery systems that reduced retrieval time by 70% and improved search relevance by 45%.

Previously at HubSpot, I developed SaaS applications and backend services for marketing, sales, and CRM products serving more than 180,000 business customers. I improved engagement by 30%, reduced page-load times by 55%, and helped deliver APIs handling over 20 million requests daily.

At Facebook (Meta), I built frontend and backend platforms supporting global-scale traffic and billions of monthly events. I enjoy building reliable distributed systems, improving performance, and mentoring engineers around scalable engineering practices.
