Daffa — Full Stack Engineer

Open to Work

Freelance · Full-time · Contract

Deliberate by design. Precise by habit.

Full Stack Engineer based in Jakarta, building distributed systems, high-performance APIs, and the interfaces that sit on top of them. Four years of shipping production software across fintech, edtech, and infrastructure.

I build with architecture first — stripping complexity until only the essential logic remains. Aerospace is my mental model for software: every component intentional, every dependency justified.

Core Principles

Architecture over shortcuts
Performance by default
Clean code as a craft
Honest collaboration

Where I've been, what I've built.

  • Led full-stack revamp of internal collections platform (Viper) to Golang and Next.js, overhauling UI/UX and RBAC mechanisms while maintaining 90%+ code coverage across FE and BE
  • Architected multi-region BigQuery dashboards across 4 countries (Indonesia, Thailand, Philippines, Vietnam), enabling each regional unit to independently track and improve collections performance at 100% business operability
  • Took full end-to-end ownership across multiple projects — driving system design, ERD, API contracts, backend logic, and dashboard UI — ensuring on-time delivery and 100% quality compliance
  • Accelerated delivery by 70%+ through pragmatic tooling, adopting Google Apps Script, Cloud Run, BigQuery Scheduled Queries, and AppSheet to ship stakeholder requests on time
  • Owned delivery of Agent Onboarding Journey Tracking platform integrating 7 stakeholder teams (HR, L&D, Trainer, TL, QC, Area & Regional Manager) into a single cross-platform system
