Backend Development

Logic and systems that carry the weight behind the scenes.

Server-side application logic, databases, and APIs — cleanly structured and built to be maintainable. A secondary service alongside my security focus, with the advantage that security is considered from the start.

Services

What I build.

APIs & Interfaces

REST APIs that are cleanly documented and easy to integrate.

Databases

Structured, performant data storage — including real-time sync where it makes sense.

Authentication

Secure user login with sessions and OAuth — implemented cleanly from the ground up.

Real-Time Systems

Live data updates, without users needing to manually refresh.

Security from the start

As a penetration tester, I consider permissions, input validation, and attack surfaces from the very first line of code — instead of patching them in later. More on the cybersecurity page.

How I Work

Three principles.

01

Direct & honest scoping

Better an honest word about scope upfront than an unpleasant surprise on the price later.

02

Transparent communication

Regular updates instead of silence until the deadline.

03

Documented code

Ready to hand over — even if another team takes over later.
