Senior Fullstack Engineer. I build data-intensive, AI-powered products — backends that move millions of records and serve thousands of requests a second, plus the LLM workflows that sit on top of them.

I care about systems that hold up under load: tested code, real observability, and migrations that don't wake anyone at 3am.

• ⚡ Scaled a migration pipeline from 10K → 3M records/hour
• 🚀 Built microservices sustaining 5,000+ req/sec
• 🧠 Developed AI-driven research & analysis workflows for a ~$39B AUM private equity environment
• 🏥 Across healthcare, e-commerce, mobility, and investment research
