ways i can help

Services

AI feature integration

LLM features wired into your existing product: chat, summarisation, extraction, agents. I design and test the evals and guardrails each feature needs, and say plainly what is and is not covered.

Production integration · prompt + eval suite · docs & handover

Typically 1–3 weeks

MVP & internal tools

SaaS or internal tool from zero to deployed: auth, core workflow, admin, reporting. Scoped to what proves the business, nothing more.

Deployed app · source & CI · 2 weeks post-launch support

Typically 3–6 weeks

Automation & workflows

n8n and API pipelines that replace manual ops work: syncing systems, generating documents, routing data between tools.

Running automation · monitoring · runbook

Typically 1–2 weeks

about

From the Philippines, for the world

I started building things on the internet out of curiosity, pulling apart websites to see how they worked, then putting my own ideas together. That curiosity became a craft. Today I work as a full-stack developer, shipping production software for clients across industries.

I care about code that earns its place: readable, honest, and actually shipped. I integrate AI where it adds real value, not where it adds noise. Based in the Philippines, collaborating worldwide.

tools

Tools and technologies

Daily drivers: TypeScript, React, Next.js, Flutter, Tailwind, Node, Postgres, Vercel, Git, Claude Code, n8n, and a lot of black coffee.

The Belief

“I believe the best products are built with solid engineering, genuine AI integration, and an obsession with actually shipping.”
