01 About

Systems that stay up, ship fast, and scale quietly.

I am a Backend Software Engineer from Malta with over four years of professional experience building reliable, efficient, and scalable software systems, specialising in C#, .NET, distributed systems, and cloud-based technologies such as AWS, with hands-on experience developing and maintaining high-throughput applications within the gaming industry.

Whether I am developing new product features, optimising existing code, or improving system architecture, I am committed to delivering maintainable, performant, and scalable solutions that can evolve alongside growing business and technical requirements.

Beyond day-to-day development, I have a strong interest in software security and emerging technologies, continuously expanding my knowledge of the OWASP Top 10, cryptography, post-quantum security, and the impact of quantum computing on modern encryption, while also exploring how AI can be used to improve development, problem-solving, productivity, and creativity.
