Software Engineer & Agentic AI · React · Next.js · TypeScript
Open to opportunities
I am a software engineer who practices agentic engineering: AI agents carry the implementation, and the judgment stays mine. I work from the command line, delegating scaffolding, migrations, API integration, tests and documentation to sub-agents that run in parallel, while I own the architecture, review every diff, and keep authentication, permissions, payments and destructive operations behind human approval. That practice has delivered maritime SaaS, an HR and payroll platform, and marketplace products. It also runs SnapInvois, a WhatsApp-native invoicing platform I founded and operate as sole engineer, live with more than a dozen businesses and shipping to production several times a week.
Agents fail in three predictable ways. They write before they understand the codebase, they report success they never verified, and they repeat a mistake next session because nothing recorded it. Shipline is a set of commands that puts a written plan, pasted evidence and a persistent lessons file in the way of each one. Plain markdown in the repo, no external service.
Speed is only worth having if it is safe. Every repository carries a standing context file of past mistakes so no session can reintroduce them, every change is verified with type-checking, tests and a production build, and I read every diff before it merges.
What that discipline catches, including a payroll parity bug and an agent fix I reverted the same day, is written up with real diffs on the AI work page.
2026 · Founder · SaaS · Founder and Software Engineer
Solo-founded, production SaaS for Malaysian micro-businesses: invoicing and record keeping both run from WhatsApp, with PDF + DuitNow QR. Live with 30+ registered businesses and its first paying subscriber.
2026 · Public Safety · Designer and Software Engineer
A free scam and phishing checker anyone can use, in English, Bahasa Melayu, Chinese and Tamil. Paste a message, get a plain answer, and a guided handoff to the right authority. Built on TypeSafe AI's Jev, a System One model that returns typed, calibrated judgments instead of prose.
2026 · SaaS Product · Software Engineer
A monorepo marketplace for AI-generated music: a Laravel 11 + Filament v3 backend paired with a Next.js 14 App Router storefront and Meilisearch-powered discovery.
2026 · Maritime SaaS · Software Engineer
A live vessel tracking dashboard for the Singapore and Malacca Straits, tracking around 270 ships at a time from raw AIS radio. Its organising idea: never show a measurement and a crew's claim as though they were the same thing.
2026 · Open Source · Software Engineer
An open-source Model Context Protocol server that gives any MCP client live AIS vessel traffic. Ask which tankers are anchored near Port Klang, or how long a laden passage usually takes, and get a real answer.

I handed over systems I had run alone. The dangerous first week is not the one with no documentation, it is the one where someone acts confidently on a stale mental model. Here is the prompt I left, with the specifics stripped out so you can use it.
