AI agents that ship. Growth systems that prove revenue. Documents that read themselves.

Currently: AI-powered growth systems at QuantumBytes

I like problems where the code has to answer to a number: leads sourced, documents parsed, users who came back.

01 About

Engineering with product accountability.

I am a software engineer in Jakarta. Right now that means building AI-powered growth systems at QuantumBytes — the ad funnel, the analytics underneath it, and the agents that do the boring parts.

Before this I migrated enterprise systems onto ASP.NET, built an adaptive assessment platform that 90% of its MSME users actually adopted, and taught a transformer to read Indonesian payment receipts.

The through-line: I ship the whole thing, then measure whether it worked.

02 Selected Work

How I think, not just what I shipped.

Narrative work from the resume — including projects with no public repo to point at.

1000+ad-sourced leads

Quantumbyte Growth & Analytics Infrastructure2025 - Present

The instrumentation and workflow layer behind every growth experiment we run.

TypeScriptPostHogMeta AdsGoogle AdsWorkflow Design

Campaign attribution across Meta and Google Ads, a PostHog taxonomy the whole team shares, and a compliance-audit funnel that scores and routes leads before a human ever touches them.

OCR-Free Payment Receipt Intelligence2025

Teaching a transformer to read Indonesian payment documents without an OCR stage.

PythonFastAPIPyTorchTransformersMobile Integration

Receipts here are messy — thermal prints, bank transfers, e-wallet screenshots. A Donut-style vision transformer parses them straight to structured fields, served over FastAPI into a mobile app.

Personal AI Agent2026

A Telegram agent with persistent memory, skill routing, and more than one personality.

LLM OrchestrationHermes9RouterTelegramAutomation

It remembers context across weeks, routes requests to the right skill, and switches persona depending on who is asking and why. Built to be lived with, not demoed.

24the only number that matters

2ne4 — 24 Game Solver & Trainer2024

An interactive solver and tutor for the classic 24 card game.

A brute-force engine checks every arithmetic path through four cards, and a tutor mode walks you to the answer instead of just handing it over.

03 Experience

Recent roles across product engineering, backend systems, and delivery.

Nov 2025 - PresentJakarta

Mid-Level Software Engineer

PT Quantum Teknologi Nusantara

I built our compliance-audit lead funnel end to end — landing flow, scoring, CRM handoff — and it now turns cold ad traffic into over a thousand qualified leads.
I designed the PostHog event taxonomy the whole team reads from, so growth experiments compare against one shared vocabulary instead of ad-hoc event names.
I keep our services honest on Kubernetes: deploys, rollbacks, and the occasional late-night incident that teaches you where the real bottleneck lives.

Full Stack Web Developer

PT Fata Organa Solusi - CAC

I migrated a legacy enterprise system onto ASP.NET with a CQRS architecture, splitting reads from writes so heavy reporting stopped dragging down daily operations.
I owned features across the stack — from SQL Server schema changes to the screens that used them — which meant no hand-offs and no finger-pointing.

Oct 2024 - Nov 2024Hybrid, Bandung

Full Stack Developer

ASTRO-ITB

I built ASTRO, a Django platform whose assessment adapts its questions to each business — 90% of the MSMEs we onboarded finished it and kept using it.
Five weeks from first commit to launch, shipping alongside an ITB research team and real business owners testing every release.
