Hamed Yousefi

Platform engineer at Polymarket, based in Dubai. I write Go, mostly distributed systems, blockchain infrastructure and LLM inference infrastructure.

Most of my day-to-day work is in private repositories, so my contribution graph shows more than the public activity below.

Now

  • gograph: v0.8.2 shipped on October 2. Next is v0.9.0, due October 19: Dependency graph toolkit. Contributions are welcome, and CONTRIBUTING.md explains where to start.

Projects

  • gograph: generic graph library for Go. Dependency graphs with cycle checks and topological order, traversal, shortest paths, connectivity and partitioning, with no dependencies.
  • gowl: worker pool for Go that also monitors the status of each process.
  • channelize: WebSocket framework for outbound streams, with several public and private channels on one connection.
  • staking: Ethereum staking backend on Lido, with Temporal workflows for staking, unstaking, rewards accounting and reconciliation.
  • athenz-agent: sidecar that wraps Athenz ZPE and ZPU, so services can use Athenz without extra code.
  • vault-eth-signer (contributor): HashiCorp Vault plugin that signs with secp256k1 keys, so Vault works as a software HSM for Ethereum.
