Lead software engineer with 9+ years building production-grade web and desktop apps using React, TypeScript, Electron, and Node.
ColombiaWhat I'm looking for
I’m a lead software engineer with 9+ years of technical experience (5+ at Perficient), delivering production-grade web and desktop applications for multinational enterprise clients across logistics, finance, and insurance. I own solutions end-to-end—from architecture through deployment and post-release stability—while keeping a strong testing discipline (contract, E2E, and white-box).
My core stack is React, TypeScript, Electron, Node.js, and PostgreSQL, and I’ve also shipped mission-critical products with large distributed teams. I bring a rare hardware-software integration background via serial-port device integration (React + Electron), and I also maintain a dual applied AI/robotics profile (ROS 2, reinforcement learning, NLP, and computer vision), including leading a team that won 1st place at RoboRAVE World Championship.
