About Me

I am an IT Leader, Systems and Software Engineer with nearly 30 years of deep technical experience (starting in 1998) spanning software engineering, cloud architecture, and IT infrastructure management. Over my career, I have held key leadership roles—including Head of IT Architecture and IT Manager—acting as a trusted technical advisor to audit core systems, lead enterprise cloud migrations, and design robust architectures.

My technical execution lies in writing clean, high-performance code and engineering software from the metal up. Whether writing cycle-accurate CPU emulators and custom OS bootloaders in C/Assembly, modernizing enterprise applications using .NET and Delphi, or developing multi-threaded, cross-platform apps with Dart/Flutter, I focus on building secure, decoupled, and highly performant systems.

Additionally, my technical expertise is backed by a diverse educational foundation, including diplomas in Software Development, IT Management, Web Development, and Counselling, alongside specialised training in Cisco networking, Linux and Microsoft server systems. This allows me to combine strict architectural precision with high-level stakeholder engagement, mentorship, and empathetic team leadership.
