Looking for: Contract / freelance work 7+ years as a backend/infra engineer, mostly in Go.
Currently senior at a fintech company working on large-scale payment infrastructure. Things I've done recently: partitioned a 5TB+ PostgreSQL transaction table (~500 RPS) with near-zero downtime, cutting query times by 20% and halving DB costs. Redesigned a reconciliation engine from Excel to XML-based processing, speeding it up 25%. Led cross-region DR drills on Aurora achieving 0 RPO / 10-min RTO. Day to day I own system design, lead a small team, tune Postgres performance at scale (vacuum strategies, indexing, query plans), build out observability with Prometheus, and keep CI/CD pipelines clean with Terraform + Git-based workflows. Previous stints include building backend services at a payments company and containerizing ML pipelines on AWS. Available for contract/freelance engagements — backend, infrastructure, platform, database performance work. Especially strong at Go services + PostgreSQL at scale.
Remote, flexible on timezones. Happy to chat — reach out via email.
Experience: I specialize in high-stakes backend infrastructure. Most recently at fintech, I led a PostgreSQL partitioning project that cut DB costs by 50% and improved query speeds while maintaining 400+ RPS. I’ve built DR strategies with 0 RPO/10-min RTO and scaled Go-based APIs that handle heavy fintech workloads.
Experienced backend engineer with 6 years in building scalable systems in fintech and sports analytics. Proficient in designing high-throughput APIs (300+ RPS), optimizing large-scale databases (5TB+), and setting up CI/CD pipelines and observability stacks. Looking for remote opportunities focused on backend/system engineering, infrastructure, or platform development.
Remote: Yes
Willing to relocate: No
Technologies: Go, PostgreSQL, AWS, Docker, Terraform, Redis, RabbitMQ, Prometheus/Grafana, CI/CD
Résumé/CV: Available on request
