Software & Systems Engineer — I take vague requirements and ship production-ready products.
I work across the full lifecycle: scoping, architecture, backend, infrastructure, deployment, monitoring, and long-term operations. My background spans backend systems, fintech and telecom integrations, mobile (Android), embedded IoT, and full-stack delivery — with a focus on reliability and getting things into production.
Four years as the sole engineer on a 4G mobile proxy SaaS platform: Android app, Windows/Linux client software, server-side relay infrastructure, customer dashboard, and payment processing — designed, built, and operated end-to-end.
