About
I am a seasoned software engineer with over 8 years of experience building scalable, production-grade systems using JavaScript, Node.js, and Python. I’ve specialized in designing REST APIs, creating real-time financial platforms, and integrating with modern DevOps pipelines. I’ve had the opportunity to lead cross-functional teams and build highly available backend systems, particularly in fintech, crypto, and AI domains.
Previously, I served as the CTO of a YC-backed startup and worked at Meta as an engineer. I enjoy driving impactful projects, such as asynchronous trading platforms and AI-powered recruitment tools. Collaboration and continuous learning are key philosophies I bring to every team I join.
