What I'm looking for

I seek hands-on engineering roles building scalable web or mobile products, working in collaborative, growth-oriented teams that value cloud-native architecture and measurable impact.

I am a Senior Full Stack Engineer with 6+ years building and launching web and mobile products, from MVPs to scalable banking systems. I co-founded a foodtech platform that served 2,100+ customers, processed $44K+ in transactions, and led end-to-end stacks using .NET Core, Node.js, TypeScript, React, Vue.js and AWS.

I excel in backend architecture, frontend development, cloud migrations, and performance optimization—migrating legacy services to .NET Core and Azure to support 25,000+ enterprise users and reducing processing time by 26%. I bring a pragmatic, results-driven approach, bilingual communication, and hands-on experience across fintech, startups, and enterprise projects.
