What I'm looking for

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.

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.
