About

I design and lead cloud-native and AI-powered systems for high-growth startups and enterprise teams, including organizations operating at S&P 500 scale, with a focus on scalability, cost efficiency, and real-world impact.

What I actually do:

  • Build and lead engineering teams that ship products on time (yes, it's possible)
  • Architect cloud solutions that scale without breaking the bank, I've saved companies 40-60% on AWS costs through strategic FinOps
  • Design AI systems using LLMs that solve real problems, not just demo well
  • Bridge the gap between "what the business wants" and "what engineering can deliver"
  • Implement DevOps practices that reduce deployment time from days to minutes
