Andrew C.

Senior backend & cloud engineer with 25 years shipping production systems in Java, Go, and AWS. I've built and operated the kind of services that can't go down: high-traffic streaming at Warner Bros. Discovery (1k–5k req/sec, 24/7/365 uptime), card management and rewards platforms at Capital One, and core banking services for Bank of America via Infosys.
What I do best:
🔹 Backend services — Java (1.4 through 25), Spring Boot, Go. Clean APIs, sensible architecture, no over-engineering.
🔹 Cloud & DevOps — AWS, Azure, GCP. Terraform IaC, GitHub Actions, CI/CD pipelines that actually work on the first try.
🔹 Databases — Postgres, Oracle, MySQL, DB2, MongoDB. Schema design, query tuning, migrations. I've fixed slow queries that other people gave up on.
🔹 Microservices & event-driven systems — Kafka, REST, message brokers, service mesh. I've broken monoliths into microservices and lived to tell about it.
🔹 Mobile + cloud — currently wrapping up an iOS/Android/AWS MVP with full telemetry pipeline.
How I work:
I own the work end to end. You tell me the outcome you need; I figure out the path. I write the code, run the deploys, debug production, and document what I built so the next person isn't lost. I've worked solo and on teams up to a dozen. Comfortable in regulated environments (finance, healthcare) and lean startups alike.
I lean heavily on modern AI tooling (Copilot, Claude, Kiro, Gemini, Grok) — I move faster than I did two years ago without cutting corners on quality.

Looking for: long-term contracts where I can own a system, not just a ticket. Available immediately. Background check / drug test ready. Eligible for U.S. secret clearance.
