Software engineer with 3 years of experience building payment infrastructure in fintech. I've worked across the full stack, from API integrations processing billions in payments to containerised services on Kubernetes. Experienced with AWS, .NET, and designing scalable systems that actually have to work.


What keeps me in this field is the stakes. In payments, the code you ship either works or it doesn't, there's no grey area when real money is moving. I'm drawn to problems where the engineering decisions have genuine consequences, and I take pride in building things that hold up under that pressure.
