Emre Küçükuzun — Software Developer

Building software that holds up in production.

I design and ship web and mobile applications end to end — architecture, database, security, interface, deployment, and everything after. Currently shipping Atlas and Perilla Portal.

About

I'm a software developer focused on building dependable products rather than impressive demos. I take projects from a blank page to production alone: architecture, database schema and query optimization, security hardening, interface, deployment, and maintenance.

Most of what I build runs in production today. Every project on this page — Atlas, Perilla Portal, and its mobile app — is a solo build from the first line of code to the app store release, with the database, security, and operations included.
