Tools I use

A fairly minimal setup. Everything here earns its place: if it's listed, I actually use it.

Workstation

  • Linux Ubuntu

    My daily driver OS. Fast, stable, and stays out of the way. Everything I need for development works well on it and I have full control over the environment.

Development

  • Cursor

    My main editor. The AI-native workflow, using GPT, Claude, and the Composer, has changed how I write and review code. It handles the repetitive parts so I can focus on the harder problems.

  • Bruno

    API testing client. Lightweight, offline-first, and stores collections as plain files alongside the codebase. A clean alternative to Postman.

  • k6

    Load testing. Scripted in JavaScript, easy to integrate into CI, and gives me confidence that systems will hold up under real traffic before they go to production.

Productivity

  • Google Tasks & Calendar

    I keep task management and scheduling in one ecosystem. Tasks for day-to-day to-dos, Calendar for blocking time and making commitments visible. Simple, fast, and available everywhere.

  • Text editor (plain text notes)

    For notes I just use a plain text editor. No syncing friction, no formatting overhead: just write it down and find it later.
