  • Cloud Infrastructure: Building and managing cloud-native applications on AWS with focus on cost optimization
  • Team Leadership: Mentoring junior engineers and driving cross-functional initiatives

My Approach

I believe in writing clean, maintainable code and building systems that can evolve with changing business needs. I'm passionate about:

  • Performance Optimization: Always looking for ways to make systems faster and more efficient
