Portofolio sistem yang saya bangun — aplikasi bisnis, API terukur, dan integrasi yang tetap stabil di produksi. Sembilan tahun mengubah requirement kusut menjadi perangkat lunak yang benar-benar dipakai.
Nine years of shipping systems, in four figures.

Four disciplines that overlap on every project.
[Jenis sistem backend yang paling kamu kuasai.]
[Jenis pengalaman frontend yang biasa kamu bangun.]
[Cara kamu membawa kode hingga stabil di produksi.]
Background jobs, dead-letter handling, and observability that tells you what broke before a user has to.
Measuring first, then fixing the actual bottleneck — N+1 queries, slow indexes, and the code that hides them.
CI/CD, containerized environments, and migrations that ship without downtime or a maintenance window.
Four steps, no agency layers in between.
01
A short call and a written brief. We agree on what "done" means and what it costs before any code moves.
02
A working spike of the riskiest part first — usually the data model or the integration — so we learn early, not late.
03
Weekly builds you can click. Feedback lands in the next build, not in a document nobody reads.
04
Handoff with docs, or I stay on for the first release week to catch what staging never does.
The tools I reach for, ordered by how often they earn their place.
Application code and HTTP APIs, built for teams that will maintain them after handover.
Relational modelling, caching, and the queue infrastructure that sits between them.
Talking to payment gateways and partner systems with retries, idempotency, and audit trails.
Reproducible environments and pipelines sized to small teams, not enterprise theatre.
Tests and type checks that catch the regression before a user does.
Server-driven and SPA front-ends that consume the APIs above without over-engineering the runtime.
