Summary
👤
Senior🎓
Top SchoolLeo Rossignac-milon is a pragmatic software engineer and co-founder with 12 years of experience building secure, scalable systems and shipping product-focused features from prototype to production. He earned recognition at Axon for leading end-to-end projects like Axon Citizen, driving architecture, security, and operational excellence, and for discovering cost-saving measures that saved the company over $500k annually. Comfortable across backend services, APIs, and operational design, he’s frequently the go-to engineer for urgent customer issues thanks to deep technical breadth and a strong sense of ownership. His career spans startups and big tech—Amazon and a brief stint at Google—where he built backend systems for Amazon Go and large-scale testing infrastructure. Now based in Knoxville, Tennessee, he applies that delivery rigor to Track My Visa, blending hands-on coding with product and engineering leadership. Colleagues rely on him not just for fixes but for questioning assumptions and architecting more robust solutions.
