Avinash Varpeti

Why over
what.

I'm a Senior Software Engineer at Travelex, building the financial infrastructure that moves money across borders. I don't just write features — I architect systems that survive edge cases, scale under pressure, and don't wake anyone up at 3am.

My work spans from pixel-perfect frontend components to event-driven backends handling high-volume FX transactions. I've led teams, shipped SaaS products from zero to thousands of users, and reduced production incidents by modelling business rules into the platform itself.

I believe understanding the why behind the what is what separates engineers who build fast from engineers who build right — and I aim to be both.
