## What I'm looking for

```text
I'm looking to build and support backend services, especially for payments, enterprise integrations, financial applications, or blockchain products, working from initial design through production.
```

## About

```text
I've built and maintained payment-gateway services at BrainRocket, delivering PSP integrations for deposits, withdrawals, callbacks, and transaction status handling. I also debug production payment flows across gateway and provider APIs in a distributed international team.

Previously, I owned Node.js and TypeScript APIs and microservices for Sky.One Solutions' enterprise integration platform, from design through production support. Across CI&T, Gold Rush, and Eight Assets, I've built blockchain monitoring services, smart-contract integrations, and web and mobile products using AWS, Solidity, React, and React Native.
```
