Owning the frontend of a QR payments network

Rehired to lead frontend direction for a QR payments network. I moved core products to Qwik, built the analytics layer and paired payment metrics with field insight.

The problem

Core products had grown slow as they evolved. The bottleneck was performance in the code itself, not users’ devices, and it was getting harder to maintain and scale.

What I did

What I learned

Being the only frontend engineer pushed me from building screens to owning outcomes: what to measure, what to solve first, and who is on the other side of the payment.
