I build with purpose - in code, stories, and life.

From deploying full‑stack apps to crafting stories that inspire, I love creating things that bring people closer to meaning.

Projects

Featured Work

Defense data platforms, a ministry site in Guatemala, booking systems for small businesses. Different clients, same question every time: who is this actually for, and what changes for them once it exists?

PlatformArchivedMar 2026 – Aug 2026

Four businesses launched on it. They outgrew it, so I took it apart.

Orbit Platform

A multi-tenant platform for small-business booking sites. Each client got an isolated AWS account, a custom domain, and a curated feature set, all managed through Terraform.

Travel

Adventures & Missions

Remote Work + Tiny Living

I code from wherever I am - from the tiny house to cafés in new cities. Freedom to focus. Simplicity to ship.

Guatemala Mission Trips

Serving in Guatemala each year has reshaped how I see the world and my purpose in it. Every year, I help work with girls in orphanages, build houses for families, and more for those in need.

Adventuring with Brezo

I married Brezo Martinez, who is the best part of every trip on that map and the reason the tiny house feels like home. Most of what is on this page happened because he kept telling me to go build it.

Australia Adventures

I spent 3 weeks in Australia visiting a friend, going snorkeling in the Great Barrier Reef, walking through the Daintree Rainforest, and exploring Sydney and Melbourne.

Why this matters

The Heart & Vision

None of this happens alone. I married Brezo Martinez this year, and he has been the steadiest yes behind every project on this site — the one who made room for the late builds, and told me to keep going when I wanted to shelve it all.

Book in progress

A dystopian novel about faith, legacy, and multiplying hope. ☀️

In a world where childbearing is controlled by decree, Sela is marked unworthy.

Hopeless until she finds a fragile scrap of paper with fading words: “Be fruitful and multiply.” That single line sparks defiance, courage, and the dream of a legacy no government can erase.

I'm sharing the creative process - from raw excerpts to breakthroughs as the story comes alive
