Hi, I'm Jona.

My Story

A short version

I started writing code because I wanted to make things that didn't exist yet. That feeling - staring at a blank file and watching something come alive - still hasn't gotten old.

Today I help businesses ship software that's fast, reliable, and a pleasure to use. I care about the boring parts (database indices, type safety, error boundaries) because they're what makes the exciting parts possible.

When I'm not at my desk, you'll probably find me at the gym, playing my guitar, or crafting the perfect cocktail.

Beyond Code

Things I love

The hobbies and habits that shape how I think - and how I build.

Tipsy Bartender

Crafting cocktails and exploring the world of mixology. A good Old Fashioned is my go-to.

Sport

Keeping active and staying fit. Whether it is the gym or a long run, movement is essential.

Guitar

Playing strings and finding melodies. A creative outlet that keeps my mind sharp.

Reading

Non-fiction, philosophy, and the occasional sci-fi novel before bed.

Music

Lo-fi while coding, vinyl on Sundays. Curating playlists is a sport.

Travel

New cities, new perspectives. Lisbon and Tokyo top the list so far.

Journey

A few milestones

2020

First lines of code

Discovered the joy of building something from nothing. Never looked back.

What I Value

Three words I live by

01

Curiosity

Every problem is an invitation to learn something new.

02

Craft

Quality is non-negotiable - even in the parts no one sees.

03

Clarity

Simple solutions outlast clever ones, every single time.
