Hi, I'm Vincen.
I build backend systems.
I care about code that's easy to follow, systems that hold up as they grow, and lately, agentic AI.
WHY BACKEND
I like the logic underneath.
I'll be honest: the frontend has never been where my heart is. What I love lives underneath. The flow of data, the way a whole system fits together when you finally get the architecture right.
Give me a hard problem and some room to think and I'm genuinely happy. The fun was never in making things look good. It's in making them think clearly.
SELECTED WORK
Work I'm proud of.
Most of my best work lives inside the products I build with a team, running in production, used by real people every day.
Gokomodo is an Indonesian agritech company changing how the country's agribusinesses buy and move their supplies: a B2B e-procurement platform, the GokoMart retail network, and a customer app. I've had my hands on all of it. These days I build the backend of the Customer App, covering core systems, performance, and security.
It's the work I'm proudest of. The architecture, a branching strategy that held up across a team, and cleaner code all came together here.
My first shipped AI thing. Feed it a document as a PDF and it reads it, pre-fills a review form with everything it found, and once a human approves, pushes it into the ERP on its own.
Calling it "an AI wrapper" wouldn't be wrong. But it turned a tedious typing job into a quick review-and-approve, and building it taught me more about working with LLMs than any tutorial did.
EXPERIENCE
3+ years building backends.
Backend engineer since September 2022, most of it spent at one company, shipping to production and learning how real systems hold up.

The place I've grown the most as an engineer: architecture, production traffic, and a lot of small lessons about building systems other teams depend on. I've touched every side of the platform. Right now I'm on the Customer App, owning backend systems, performance, and security.
- Cut a critical SQL query from >15s to ~400ms, a ~38× speedup.
- Shipped an LLM-powered vendor-bill scanner: PDF in, review form out, bill created in the ERP automatically.
- Built the loyalty-program backend behind retail revenue averaging IDR ~400M per shop per month.
- Strengthened transaction anomaly detection for e-procurement, catching fraud before it lands.
- Worked with ERP teams to keep data in sync across applications, ending manual reconciliation.
- Built audit-logging middleware and wired up Sentry, so issues get found (and fixed) faster.
- Optimized mobile-app image loading and shrank the cache footprint, which helps on slow connections.
- Owned backend features end-to-end, from schema design and APIs to production rollout and monitoring.
THE TOOLBOX
What I reach for.
I care less about collecting tools than about picking the right one and using it well.

New obsessions
RIGHT NOW
Bringing backend instincts to AI.
I'm deep in AI right now: LLMs and agentic systems. I'm working toward being an AI engineer, carrying over the same instincts I trust in systems, structure, and reliability. It's a field that's still figuring itself out.
My first LLM feature is live at work, a vendor-bill scanner that turns PDFs into ERP entries. It won't be the last.
It's the most fun I've had learning something in a long, long time.
