About
If you want someone who can take your product from idea to impact, I’ve done it at scale. I’ve built and maintained applications used by over 3 million users and supported financial systems in a bank that processed more than 3 billion dollars. I work across Java, Python, and C# with deep experience in Spring Boot and Django. I focus on clean architecture, reliability, and fast delivery. I treat every problem like it is my own and I care about building software that removes friction and moves the business forward. I join teams to make their load lighter and their product stronger. Ready to help you ship what actually works.
