Senior Software Engineer, Release & Reliability at Nethermind, based in Buenos Aires.
I run releases for the Nethermind execution client. Nothing reaches node operators until it has passed our soak fleets on mainnet, Gnosis, Sepolia, Hoodi and OP networks. Most days that means:
- Release engineering: release branches, backports, smoke-test triage, and separating real client bugs from CI noise.
- Test infrastructure: Terraform-managed node fleets on GCP, self-hosted CI runners, and Prometheus/Loki dashboards with alerts for stalls and memory.
- Fork days: live monitoring of every node's health and chain agreement during network upgrades.
- Client fixes: sync, pruning, txpool, networking and JSON-RPC hardening.
- AI tooling for the team: LLM pull-request review in CI, and routing CI failures to the engineer responsible.
Before that I was one of the first engineers on Juno, Nethermind's Starknet full node in Go, and I've worked on Sedge, a one-command node and validator setup tool.
Public numbers: 118 merged PRs in nethermind, 104 in sedge and 32 in juno, plus 250+ PR reviews in nethermind.
On my own time: Payverge, an open-source restaurant operating system in Go and Next.js, and small developer tools such as grok-in-codex.
