Azhar Maulana[ JAR ]

I build systems end-to-end — write the code, test it to failure, ship it, and run the company that uses it. QA, mobile, web, AI agents.

About

WHO YOU'RE TALKING TO

Not one lane. The whole stack — and the business behind it.

BuilderQA EngineerIndie Founder

I never picked one lane. I learned QA to understand exactly how systems break, mobile and web to build them, and AI automation to make them run themselves — because I run a business that needs all of it.

I care about systems end-to-end: from a JMeter graph hunting a rate limit, to a Flutter build shipping to Windows, to a customer's WhatsApp message answered at 11pm by an agent I wrote. I'd rather ship something boring that works than something clever that pages me at 3am.

Engineer and founder in one. The tools I build serve a company I'm accountable for — so they have to actually hold up.

Selected Work

THINGS I'VE SHIPPED

◆ ANCHOR

OpenClaw

WhatsApp AI Customer-Service Agent

Built from scratch — an LLM agent living on WhatsApp for PT. Alfa Omega Indolab. It handles customer inquiries automatically, routes them to the product catalog, and notifies admins of every lead. Guardrail logic keeps it from ever making a decision on its own.

IMPACT

Real front-line CS for a real distribution business, with cost controls: message debouncing, rule-based intent routing, and model tiering.

Lab Equipment Distributor — Founder

I own and run a lab-equipment distribution company carrying Hanna, Brookfield, IKA, VELP, and Thermo Scientific. I build the internal tooling myself — the AI CS agent, the stock-management app, and more.

IMPACT

Not just an engineer — a founder. The products I build serve a business I'm accountable for.
