Rockstar🎓
Top SchoolMarcos Dione is a seasoned Systems Developer and Administrator with 18 years of experience building reliable, distributed infrastructure and automations from Marseille. He blends deep systems-level expertise—databases, caching, in-memory storage and VoIP—with SRE and SiteOps practice, most recently at Tripadvisor after roles at Cloudian and Amadeus. Marcos is a pragmatic problem-solver who improves observability and resilience through monitoring, Salt, Zabbix/Grafana and careful memory/cache management. An early coder who started at 13, he contributes to notable open-source projects like requests and osm2pgsql, focusing on robustness and performance rather than flashy features. Colleagues rely on him to tame legacy systems, migrate complex clusters and quietly harden production infra.
