A brief look at my path in programming, security and technical support.
I started programming as a teenager and in the past few years I’ve been working professionally with PHP, C# and web development. Along the way I’ve built e-commerce and business websites, different Telegram bots, Windows utility applications and also handled WordPress site management.
I actively work in web security, penetration testing & securing websites as well as setting up and maintaining VPS/hosting environments, always trying to keep projects not only functional but also robust and secure.
I’m highly interested in continuous learning and always looking for new technologies, best practices and ways to improve code quality and infrastructure.
