Selected as 1 of 100 fellows for Meta's 12-week production-engineering curriculum with Major League Hacking, where I learned directly from Meta engineers and applied those lessons to real services. I kept a Flask/MySQL service stable on a memory-constrained VPS, shipped a second Go/SQLite service on its own host, and automated the release and monitoring path around both.
A selective 12-week fellowship, one of 100 seats nationwide, meant getting hands-on with the machinery beneath reliable services instead of reading about it. I provisioned and ran real Linux hosts on CentOS, not a sandboxed tutorial environment, and kept them stable under real memory pressure.
I put NGINX in front of the service for TLS termination, routing, and rate limiting, then replaced manual releases with GitHub Actions gated on tests, security scans, and health checks.
I set up monitoring with Prometheus, cAdvisor, and Grafana over host, container, and network metrics, cutting the time it took to detect a problem by 80%.
Alongside the fellowship's Flask/MySQL service, I built and shipped a Go/SQLite terminal app that anyone can reach over SSH, running as a self-healing Docker Compose service on its own AWS EC2 host.
