Martten Mitri / Full-stack developer

I build

Odoo modules that make complex workflows clearer and easier to use.

I am Martten, a 27-year-old full-stack developer with a Bachelor's degree in IT and master's-level studies in Business Information Technology at TalTech. I like building clean tools, fixing weird workflow pain, and making systems behave nicely, from client-facing websites and Odoo customizations to home infrastructure that runs quietly in the background.

Experience

Work that moved from websites into business systems.

Personal systems

The kind of engineering I keep running at home.

NAS

Local Subscription Replacement

Designed and built a local NAS system to replace subscription services with self-hosted media, photo management, backups, containers, and dashboards. Automated maintenance and service workflows keep everything reliable day to day while keeping personal data and infrastructure under my control.

How I work

Minimal interfaces, sturdy logic, fast feedback.

I care about the details that make software feel considered: responsive layouts, readable data, low-friction flows, and code that stays understandable after the first version ships. Outside work, I like to travel, follow finance, and over-engineer my apartment just enough.
