I'm Farhan

Senior Software Engineer with 10+ years shipping production systems at scale to millions of users, at Gojek / GoTo Group since 2018. I started as a Mobile Engineer, moved into backend in 2023, and now work as a Fullstack Engineer with technical lead experience, owning end-to-end food delievery and financial merchant domain, identity, and access infrastructure for GoFood and GoPay on Merchant Platform, and expanding into more than that.\n\nMy core strength is bridging mobile, web, and backend. I design, build, and operate systems end to end, from Kotlin Android UIs to Go, Ruby on Rails, Typescript, and Elixir microservices. I write RFCs and ADRs, drive zero-downtime migrations, handle incident response for L4-L5 severity issues, and mentored engineers across multiple teams.\n\nWhat I bring to the team, in recent work:\n• Led Project Gober end-to-end, solo, frontend through backend through incident recovery. Contributes roughly IDR 20B/year in revenue.\n• Designed an ABAC (attribute-based access control) framework that cut new access-control policy rollout time by ~40%.\n• Built the full backend for Change User Information: BFF, workflow engine, auth, FRS, and API gateway layers, 10+ MRs across 4 repos in 6 weeks.\n• Self-initiated a test coverage and automated MR review rollout across 11 repositories that had zero prior quality baseline.\n• Led two Rails major-version upgrades and a Skynet/Tencent cloud migration, zero rollback.\n\nStack: Kotlin, Android (Jetpack), Flutter, Kotlin Multiplatform, Go, Ruby, Elixir, TypeScript, Python, PHP, Node.js, Next.js.\n\nI thrive in remote, on-site, and hybrid work environments that able to adjust myself collaborating worldwide. This global perspective allows me to broaden my horizon to tackle complex problems that demand creative thinking. My curiosity drives me to explore new possibilities and stay up to date with the latest advancements in the field. Moreover, outside my day job, I mentor through Bangkit Academy, Praktisi Mengajar, and GIGIH. I contribute to open source and write about what I learn. Currently exploring Rust, blockchain on the side, and anything at the intersection of performance and developer experience, I am passionate about contributing to open-source projects.\n\nI am open to conversations about engineering challenges, software systems, mentoring, or new opportunities.
