Experience across ambitious teams

Engineering leader with hands-on delivery across fintech, infra, and product organizations: I supported a banking app with 30K concurrent users, operated a central bare-metal datacenter and 1,000+ remote Cisco/server nodes for a national electronics retailer, launched a mobile banking product as Product Owner, built and led a full-stack gamification platform for enterprise support, and worked as a developer in 3 of the country’s top 4 banks. Alongside extensive freelance frontend work, over the last 7 years I have focused on TypeScript, library authoring, and solving performance and architecture bottlenecks while consistently leading engineers technically and supporting DevRel initiatives.
