## What I'm looking for

```text
I'm looking to grow quickly while contributing to high-impact crypto infrastructure, helping developers onboard successfully, resolving complex integration issues, and turning customer feedback into product improvements.
```

## About

```text
I've supported enterprise blockchain infrastructure at Ankr, debugging SDKs, APIs, nodes, and staking integrations while helping clients overcome implementation blockers.

I built monitoring mechanisms with Grafana and webhooks to analyze client-testing errors, and partnered with Product and Engineering to prioritize fixes using client feedback, telemetry, and status updates.

At Consensys, I supported hundreds of MetaMask users daily, provided tailored technical guidance, and helped reduce bug-resolution time by 20% through close collaboration with product teams.

I've also built DeFi and Web3 products, including Solidity smart contracts for Jackrabbit Finance and an NFT marketplace. I bring hands-on frontend, API, developer-support, documentation, and customer-success experience to crypto infrastructure teams.
