I ship AI into productspeople actually reach for.

Product engineer shipping mobile and full-stack systems at 200K+ customer scale. I treat AI as production craft: LLM integration, prompt design, and AI product UX.

I don't just write code. I build things that earn their place.

Here is how I think about the work, whether I'm leading a team or shipping a product solo.

“A fast learner with strong project management skills and excellent communication. He consistently delivers quality work and meets requirements within the given timeframe.”

Noel Marcelino, Academic Mentor

I solve for the user, not the spec

Before writing code, I dig into who hurts and why it matters. The best features anticipate what people need, not what the document prescribes.

I ship fast, then sharpen with evidence

A working product in real hands teaches more than months of planning. I reach production quickly, then let actual usage shape the next decision.

I make the people around me faster

At UnionDigital I built shared infrastructure so two teams could ship independently. Good architecture compounds long after launch day.

I care about the details users feel

Response time, empty states, the weight of a tap. The gap between a product people tolerate and one they reach for lives in the small decisions.

The short version of why teams keep bringing me back.

04

Solo product launch

The fastest way to understand a product is to build one. So I keep building, learning, and breaking things on purpose.

Nara, a trading journal for disciplined traders

Learning right now

AI product patterns and on-device inference

Daily driver

Flutter, Next.js, and a very full coffee cup

Off the clock
