Ricardo Zavala

Staff Software Engineer in Henderson, Nevada. I build dependable full-stack products where backend correctness, product decisions, and production reliability meet.

I have 10 years of experience across distributed systems, fintech, federal platforms, healthcare technology, commerce, and AI-assisted workflows.

What I work on

  • Event-driven and distributed systems that stay correct under retries, concurrency, and messy data
  • TypeScript, React, Node.js, Python, Go, PostgreSQL, AWS, REST, GraphQL, and observability
  • AI-assisted product workflows with explicit boundaries, validation, human review, and evaluation
  • Product-facing software where the service design and the user experience need to work together

Selected work

Project What it demonstrates
Enroll Concurrent enrollment flows using PostgreSQL locking, waitlist jobs, and an audit trail.
Blaqjaq A 3D blackjack game with a pure TypeScript engine, 159 automated tests, and production load-test evidence. Play it.
Nomadhood A full-stack location discovery product using Next.js, tRPC, Prisma, PostgreSQL, and MapLibre. View live.
Emergency Lifeline Auditor A county-level disaster-readiness explorer built from five public federal datasets.

Available for the right problem

I am open to senior backend, full-stack, and staff-level opportunities—especially where there is a real system to improve, a product decision to clarify, and a team that values software it can stand behind.
