What I'm looking for

I'm open to senior smart contract or backend roles in Sofia or remotely.

At LimeChain, I worked on Coinbase tokenization projects, including building the NestJS backend for a tokenized-loan marketplace and delivering Coinbase Admin features from Go gRPC endpoints through to React. I also extended the event system for Coinbase's tokenized-stocks platform and led migrations across event publishers, PostgreSQL schemas and Kafka topics.

Before that, I built DeFi infrastructure at ChangeX and front-end features at Blubito. I build Web3 systems from smart contracts through deployment, and my proof-of-work chain project mirrors pre-Merge Ethereum and runs on AWS with Terraform and GitHub Actions. I'm open to senior smart contract or backend roles in Sofia or remotely.
