What I'm looking for

I’m looking to build backend systems and APIs—reliable payments, scalable services, and clean documentation—where I can improve onboarding, streamline processes, and partner across engineering to deliver measurable customer impact.

I’m a Senior Software Engineer working across backend & systems, delivering production services and improving how teams ship. I deployed an upgraded recurring payment solution across cloud infrastructure, serving 9 enterprise customers, and I led documentation and on-boarding improvements that reduced ramp time for new engineers.

Across 2020–2024, I delivered 47 custom systems spanning telephony, SMS, web, and custom Agile / Scrum applications. I also championed process streamlining initiatives adopted across the full development team, supported rapid customer launches by self-teaching new architecture before launch, and expanded cross-team coordination to improve delivery visibility and reduce friction.

Earlier, in Customer Support Engineering (2019–2020), I resolved 215 support tickets and 29 critical system-down incidents, earning recognition for clear communication and fast, reliable follow-through. I strengthened my engineering foundation through a QA internship where I extended an automated C# testing framework and built 12+ new test cases, and I keep building outside work—like a Go + SQLite marketplace web app and hands-on homelab infrastructure with Docker, Jellyfin, and Matrix (Dendrite).
