Custom web, mobile and desktop application development
I am a qualified Software Developer and Tester, building web systems, mobile applications, desktop programs and data-driven solutions through my own projects.
My goal is to create understandable and useful digital solutions for smaller organizations, institutions and individuals.

Service areas
How I can help
Planning, developing and testing smaller, clearly scoped digital solutions.
Mobile applications
Android-based apps, advisory tools, data collection and information applications.
Desktop applications
C# / WPF programs and smaller administrative or educational desktop tools.
Backend and database
ASP.NET Core APIs, MySQL databases, JWT authentication and CRUD systems.
Cybersecurity mindset
Security-minded development, access control, data handling and permission considerations.
Technical background
Hardware-adjacent and cybersecurity experience
Alongside web and software development, I have also worked with hardware-adjacent technologies. This helps me understand software not only from the user interface side, but also from a system, network and device-level perspective.
Focus
Software + hardware + security
Raspberry Pi and Linux systems
I have worked with Linux-based systems, network configuration, services and cybersecurity-oriented tool environments.
Arduino and microcontrollers
I have basic experience with Arduino-based control, LCD displays and simple electronics circuits.
Electronics basics and soldering
Through my electronics studies, I gained basic experience with board assembly, soldering and controller-chip based solutions.
Networks, NFC and radio frequency
For learning and prototyping, I have explored network protection, NFC, radio-frequency technologies and security-aware testing.
Experimental hardware and cybersecurity project
I built an experimental solution where a soldered controller board and LCD display were connected to an application workflow. The goal was not industrial hardware development, but practicing how software, hardware and a cybersecurity mindset can work together.
