Full Stack Engineer with 6+ years shipping mission-critical products — from real-time drone operations at Matternet to compliance SaaS at Themis and Messenger Kids at Meta. I thrive at the intersection of product thinking and deep technical execution, working across React, Node.js, Python, and Go to build systems that scale. Passionate about GIS, real-time data, LLMs, and pushing the boundaries of what software can do.
