Hafiz Putra Ludyanto

I’m a Senior Backend Engineer with 7+ years building Go/Golang backend systems, with a track record of shipping production services and improving reliability at scale. I’ve contributed to Go microservices platforms and owned end-to-end backend delivery across distributed, remote teams.

At FrankieOne, I owned compliance verification delivery across 5+ repositories, taking features from RFC to production with structured post-release monitoring. I reduced incident resolution time by improving audit trail visibility, structured logging, and targeted diagnostics, and I strengthened quality by building end-to-end and integration test suites that reduced regressions.

At Flip and Kitabisa, I handled high-throughput notification and verification workloads, supporting 11M users and multi-channel messaging. I reduced medical verification attempt rates by 23% and decreased multiple rejected medical verification requests by 31% through systematic backend optimization, validation logic improvements, and better error handling.

Most recently, I contributed to a Go microservices platform at Astro, using gRPC/Protobuf for type-safe inter-service communication and building services with Clean Architecture and Domain-Driven Design. I’m also an AI-assisted developer—using tools like Windsurf, Claude Code, and Codex to accelerate workflows—while keeping a strong focus on observability, maintainability, and clear system design.
