Portrait of Maisam Haider

I’m Maisam — a software engineer and founder of Zilloris. I build focused apps around one idea: solve the problem without demanding more of your life.

2026
The rule

One app, one problem.

Every app I build does one thing. If a feature would give you a second reason to open the app, it becomes its own app.

01 — About

Every app on your phone wants more of your time. I build the ones that want less.

I’ve been building production Android apps since 2019. One Page went live on Google Play in October 2026. Manuscript and Sabr are in testing, and more are on the way. Alongside the studio I’m doing a Master of Computer Science at CESI (2025–2027).
