ABOUT ME

Senior Software Engineer | Rubyist | AWS Expert

With over 8 years of experience, I specialize in solving the most complex backend challenges for SaaS platforms. If you're struggling with slow APIs, database bottlenecks, or an unreliable cloud setup, I can help you diagnose the root cause and implement scalable solutions.

My core focus is on performance and reliability. I've reduced 4+ hour bulk operations to 45 minutes, built search systems for over 50 million records, and cut observability costs by 70% while improving system insight. My expertise covers deep performance tuning in Ruby on Rails, database optimization (PostgreSQL/Redis), and building automated, production-grade infrastructure on AWS with Terraform and GitHub Actions.

Whether you need a quick debugging session, an architectural review, or long-term mentorship, I'm here to help you build fast, stable, and maintainable software.
