About

Clear thinking, careful building.

I'm a detail-oriented developer completing a BS in Information Technology at Agusan del Sur State University.

I've built systems for a farming cooperative, a government training institute and a local disability affairs office: work where people depend on it being right. That is where I learned to care about honest states, readable type and interfaces that explain themselves.

CuriosityI ask why before I ask how.
Problem-solvingRequirements first, pixels second.
Continuous learningAlways one tool deeper than last month.

Experience and process

How the work gets done.

  1. 01

    Understand the problem

    Talk to the people who will use it and write down what must be true.

  2. 02

    Plan the experience

    Map the flows and states before any screen exists.

  3. 03

    Design and build

    Build in small working pieces, interface and logic together.

  4. 04

    Test and refine

    Put it in front of real users, then fix what they trip on.

  5. 05

    Deliver and improve

    Ship it, watch how it's used and keep tightening.
