Summary
🤩
Rockstar🎓
Top SchoolIgnacio Tolstoy is a Lead Software Engineer based in Barcelona with 12 years of experience building high-throughput, distributed systems and mentoring engineering teams. Currently tech lead on New Relic’s ingest path, he helps operate ~30 services processing over 4 billion messages per minute using Kotlin, Java and Kafka while safeguarding SLOs and platform health. He’s equally comfortable shaping architecture and developer experience—having driven large migrations from monoliths to microservices, built deployment frameworks with Ansible/Jenkins, and improved entity-definition validation and tooling in open-source projects. A pragmatic polyglot who favors the best tool for the job, Ignacio prioritizes readable, context-rich code, direct empathetic feedback, and team ownership of success and failure. He’s been programming since age 11 (once shipping a batch-file Snake game) and prefers fully remote roles where teams are empowered to make decisions.
