## What I'm looking for

```text
I'm seeking remote Solidity, Web3 backend, or full-stack roles, on a contract or full-time basis. I'm available immediately.
```

## About

```text
At PrediX, I built an end-to-end EVM prediction-market stack across contracts, backend services, oracle operations, an indexer, and a Next.js UI. I shipped a UMA-style bond ERC20 with 35 Foundry tests and a Sepolia-verified deployment.

I also delivered a wallet-connected trading UI and implemented a C++20 matching core with Java 21 orchestration, supported by 54+ tests. Previously at LTP, I owned the engine-to-exchange order pipeline for a crypto trading OMS and implemented maker-fee routing and operations APIs.
```
