About Me

The Story So Far

It started at Amazon, where I joined as an ML Data Associate. Beyond the core role, I built internal tools using Flask and SQLite for my team, and got the opportunity to work with the Kindle Team on an Ion Viewer. That taste of building real software sparked something - I wanted more.

So I joined Roanuz, where a small team was building something ambitious. Over six years, I grew from writing production Python code to leading a team of five engineers, architecting systems that would eventually handle 4 billion API requests. I also worked extensively on AWS - building and managing the infrastructure that powered our APIs. Those years taught me everything - from debugging 3 AM production issues to designing billing systems that process real money.

Today, I'm a Senior Consultant at Thoughtworks, and I keep seeking new frontiers. After years of API development, I've dived into the world of LLMs, building AI agents with LangGraph and CrewAI. I'm also deeply interested in understanding the complete lifecycle of a project - from code to infrastructure, including the DevOps challenges that come with running systems at scale. What drives me hasn't changed - a deep curiosity and admiration for people who find innovative ways to solve problems. Whether it's a database query, a CI/CD pipeline, or an AI agent, I find joy in building elegant solutions to complex challenges.

Curious Mind

Always exploring new technologies and approaches to solve problems more elegantly.

Craft-Focused

I believe in writing clean, maintainable code that stands the test of time.

Impact-Driven

Focused on building solutions that create real value and scale to millions.
