Available for projects — late 2026

Full-stack developer crafting reliable software.

I design and build full-stack products end to end — ERPs, marketplaces, fintech apps and AI tooling — from the first schema to the last deployment.

I also spend time giving back — I have contributed to open-source software across 5 organizations with 35 merged pull requests.

What I use

Tools of the trade.

Hardware

Mac Studio

The machine that does the heavy lifting — builds, containers and long-running dev servers.

01 / 17

Lenovo Ideapad

My Linux laptop. Light enough to carry everywhere, fast enough to ship from anywhere.

02 / 17
Hardware

Linux

The OS I actually work on. Scriptable, stable and mine.

03 / 17
Hardware

Keychron

Mechanical and hot-swappable. Typing all day without fatigue.

Software

Software

Linear

Issue tracking that doesn't make you hate issue tracking.

For writing prose. Nothing else comes close.

09 / 17
Design

For the 5% of animations that need orchestration.

13 / 17
Life

Kindle Paperwhite

Reading on a phone is not reading.

14 / 17

Aeropress

The only coffee gadget that has never disappointed me.
