Writing & Case Studies
Editorial content that explains what I build and why it works.
This portfolio brings together my projects and writing in one place. I use it to document the apps I build, why I chose a particular stack, and what I learned shipping real products. Each case study covers the motivation, features, implementation details, and stack tradeoffs behind a specific project — from native Android modules to real-time sync engines.
What you will find here
- Turning product ideas into shipped apps with React Native, Next.js, and TypeScript — from concept to Google Play listing.
- Detailed project breakdowns from Vehiclo, Media Tracker, Galazio, and other mobile builds, including the real architectural decisions behind each one.
- Writing practical notes on app architecture, native module development, API design, performance optimisation, and UI patterns I use across projects.
- Documenting stack tradeoffs and lessons learned — what worked, what I would change, and why certain technologies fit better than others.
The goal is to make the site useful as both a portfolio and a record of the work behind it.
