Becoming
A habit-building app for iOS and Android, designed and built in-house. Instead of just logging streaks, Becoming notices when you're about to give up, asks what went wrong, and adapts your plan, while a unique bonsai tree grows with your consistency.

Marouane Elaich
Founder & Principal Engineer
Marouane is a software engineer who has spent his career shipping products across the stack: mobile, web, backend, and blockchain. He founded Elaich OÜ in 2024 to run his contracting practice as a proper company: one engineer, full accountability, no hand-offs.
Every project at Elaich is built by him, end to end, which means the person you scope the work with is the same person writing the code.
