About me
Bandung, West Java
I build web apps end to end and ship them alone: interface, API, schema, deployment. Client work since 2024 taught me to start from whoever has to use the thing. MangMicro and MangQuiz came first, from one observation: lecture material is long, and the time to absorb it is short. The past year went into products built on language models that people pay for: MangRAG puts an answer bot on a business's own documents on monthly plans, while NusaGate meters and bills model traffic per request.
I work both ends of the stack and don't treat one as the interesting half: React and Next.js on the client, Laravel, PostgreSQL, pgvector, and retrieval pipelines on the server. Performance, readability, and keyboard accessibility are things I won't trade away, and on the server that same instinct shows up as answers that cite their source instead of guessing.
The work I want more of is LLM engineering rather than AI as a feature: retrieval that holds up against real questions, evaluation before shipping, and a cost per request low enough to charge for. MangRAG and NusaGate are already that; what I'm after next is harder versions of the same problem.

- TypeScript
- Laravel & Inertia
- Postgres & pgvector
- Gemini API
Selected projects
Five shipped products, all publicly accessible. Two are about learning, one about writing, one for teams building chatbots for their clients, and one a commercial AI gateway. I did the entire process myself, from interface design to deployment.

Plate 04RAG SaaS · 2026
MangRAG
A SaaS that puts an answer bot on a business's own site, trained on its own documents: upload a catalogue or FAQ, paste one line of code, and every reply cites its source. Bots wear the client's own colours and greeting, run only on domains the owner allows, and start answering in the first second. Sold on monthly plans from IDR 75k to IDR 999k.

Plate 05AI Gateway · 2026
NusaGate
A commercial AI gateway priced in rupiah: one drop-in endpoint fronting ten models from DeepSeek, GLM, and Google at 55-77% below the vendors' own token rates. QRIS top-ups from Rp 10k settle on Midtrans webhooks, balance is deducted atomically per request, prepaid Coding Plans hand back more API credit than they cost, and a drained balance returns 402 instead of 500. Measured on 30 Sep 2026: 81 accounts, 30 active, 36,500+ requests, Rp 536k collected, and a 1-billion-token subsidised pool claimed 6,900 times and exhausted within a day.

The numbers below are read directly from GitHub and only cover public repositories. Most client work and running products live in private repositories, so what you see here is a working rhythm, not the full output.
