Freelance Full Stack Developer: One Expert from Interface to Server

I build the interface, backend, database, mobile app and server infrastructure as one coherent architecture. Zero cross-team coordination overhead.

Quick answerA full stack developer is a software engineer who builds the frontend (user interface), backend (server side), database and server infrastructure together. Hakan Sevimoğlu has been building end-to-end products for 18 years with Laravel, CodeIgniter, PHP, React, Node.js, MySQL, Swift and Kotlin.

Why hire a full stack developer?

Working with separate frontend, backend and mobile teams adds meetings, API contracts and split responsibilities. With a single full stack developer, the data model, API and interface are designed to fit together from day one, so debugging and new feature development move faster.

Taking over an existing project is also possible: first the codebase, database structure and real API traffic are reviewed, then development continues without breaking what already works.

What I offer

  • Frontend

    Fast interfaces with React, vanilla JS SPAs, PWAs and service workers.

  • Backend

    PHP 8 / Laravel, CodeIgniter, Node.js and Python Flask services.

  • Database

    MySQL, PostgreSQL, SQLite; index and query optimization.

  • Mobile

    Native iOS apps in Swift/SwiftUI and Android apps in Kotlin.

  • Server & DevOps

    cPanel, Linux, SSL, backups, cron jobs and monitoring.

  • API & Integrations

    Payment, shipping, ERP and marketplace integrations.
