A technologist with a builder's heart.

Hello — I'm a technologist from Bali, Indonesia. I've spent the last two-plus decades building digital platforms across marketplaces, retail, logistics, fintech, and now banking — the kind of systems that need to keep running while the business reinvents itself around them.

My work sits at the intersection of strategy, architecture, and people. I've led multi-year roadmaps, migrated legacy stacks in months, bridging the gap between startup agility and enterprise stability.

I am a lifelong technologist at heart who finds joy in the craft and the conundrum of complexity in it.

Software Engineer

CMS · OnlineShop · Web 2.0

Where it all started. Building sites for clients across Belgium, the Netherlands, and Luxembourg in the early Web 2.0 era — bespoke CMS, custom e-commerce, a lot of Flash, and an embarrassing amount of enthusiasm for CSS3.

  • Combined dynamic animation and CSS3 craft into engaging, characterful interfaces.
03 — Principles
Hard-won, opinionated

How I build.

P / 01

Strategy is just architecture, drawn larger.

Three-year blueprints, quarterly bets, weekly trade-offs. Same skill, different zoom.

P / 02

Velocity and quality aren't a trade-off.

5× faster delivery and 60% fewer defects, in the same year. The lever is craft, not heroics.

P / 03

Teams scale on culture, not headcount.

2 → 50, 5 → 100, 400 → 700. The shape changes; the principles don't.

P / 04

Bet on platforms, not features.

The features get rewritten; the platforms outlive the org chart.

P / 05

Migrate while the train is running.

Stack swaps, M & A integrations, regulator deadlines — done in months, not years, without dropping a packet.

P / 06

Be a useful nerd.

Geeky enough to read the code, strategic enough to read the room.

The Stack Is Rarely the First-Order Problem
