Jason De Jesuz
Software engineer focused on turning complex data into products people use. Shipped products used at national scale — from rebuilding Astron Energy's digital platform to building LoopedinLearning from the ground up. Early engineer at Zilch before their path to becoming a unicorn.
Currently building Dirt — making land development data accessible and actionable.
Background
I grew up in South Africa in a family of entrepreneurs. My father built an international packaging machine company, and my mother — one of the first female Chartered Accountants in South Africa — co-built the business alongside him. Building things from scratch is something I have always known.
I started working in tech at 18, and by my early twenties I was leading engineering teams delivering products for major brands across automotive, energy, and fintech. That work took me from South Africa to Singapore, and now to Dublin — each move driven by the next opportunity to build something meaningful.
At 27, I am focused on one thing: building Dirt.

A snapshot of my open source contributions and activity over time.
Reading
Functional Programming in Scala by Paul Chiusano and Rúnar Bjarnason — a rigorous walk through functional programming from first principles. I am working through it to sharpen how I think about composition, type-driven design, and handling effects in the systems I build.
Shoe Dog by Phil Knight — the founder of Nike's memoir on building the company from a car-boot sales operation into a global brand. I am reading it for the unvarnished look at what it actually takes to keep a company alive through the early, uncertain years.
Meditations by Marcus Aurelius — the private notes of a Roman emperor writing to himself about duty, mortality, and self-discipline. I return to it when I need to recalibrate and remember what is worth caring about.
Daily
The Daily Stoic by Ryan Holiday — a short passage each morning drawn from Stoic philosophers. A small ritual to start the day with intent.
