Two years in technical support taught me to diagnose under pressure. Right now I'm rebuilding that instinct for infrastructure — real projects, real incidents, real cost anomalies — not just certificates.
Built and deployed a real production booking system for an actual small business — not a demo. When the original host's trial expired with about a day's notice, migrated the entire backend and database (Render + Neon) live, without downtime, while simultaneously running a full security audit.
Found and fixed a stored XSS vulnerability where unescaped customer input could execute in the owner's authenticated session. Scrubbed a leaked credential from full git history with git-filter-repo. Found and fixed a double-booking bug that let "completed" appointments silently free up their own time slot.
Honest note: live and stable, but still early in real customer adoption — the engineering is production-grade even though usage is still small.
Deployed a static site on EC2 + Nginx as a deliberate learning exercise — full manual server setup, SSH, reverse proxy config. Then AWS's own Cost Anomaly Detection flagged a real problem.
The lesson that stuck: know which AWS free-tier benefits are time-limited (EC2, RDS) versus permanently free (Lambda, CloudFront, ACM). Built the replacement on the permanent tier. Zero cost since.
Open to junior-to-mid DevOps, cloud infrastructure, and SecDevOps roles. Not looking for on-call-heavy SRE or customer-facing calling positions.
