05 / Retrospectives

A year-by-year record of work, learning, and growth.

2026

Building for failure, not only success

In progress

My work shifted from delivering features to examining what happens after a request succeeds: whether events remain recoverable, deployments stay repeatable, and production failures leave enough evidence to diagnose.

2025

Learning production constraints

Working on a cash-management platform and an event-booking product made performance, session recovery, shared front-end standards, and deployment discipline concrete rather than theoretical.

2024

Connecting product decisions to implementation

I worked across public-sector software, logistics, and product teams while helping shape Countlorie, Calme, and Eco.in. The year made role boundaries clearer: product direction, interface quality, and engineering execution depend on one another, but they are not the same responsibility.

07 / Testimonials

Specific words from people I have built with.

Arya rebuilt our audit pipeline so failures no longer meant lost records. The design was documented well enough that the rest of the team could extend it without him.
Dewi PrakosoEngineering Lead, Nusantara Systems
He asks the questions that expose the real constraint before writing any code. Our booking flow shipped smaller, clearer, and far more reliable because of it.
Miguel SantosProduct Manager, Freelance Client
The clearest technical writer I have worked with. His notes turned a fragile deployment process into something the whole team could reason about.

08 / Outside the work

Most weekends I am on a bicycle somewhere between Surabaya and the coast. Distance is where I do my clearest thinking about hard problems.
