About me

Passionate about building software that matters

At 23 with solid experience in backend and full stack development, I specialise in building robust, scalable solutions using .NET as my primary technology.

I'm enthusiastic about challenging projects that require performance optimisation, clean architecture and attention to detail. Currently focused on business automation with N8N and web application security.

A continuous learner who keeps up with technology trends and always seeks to improve their skills and deliver real value.
