Building Systems,
Not Just Websites.

I specialise in tackling technical challenges that don't have off-the-shelf answers. Whether it's fixing critical bugs, building custom applications for niche industries, or integrating systems that weren't designed to work together — I figure it out.

A decade of investment banking technology taught me to be methodical: understand the constraint, identify what's actually broken, fix it properly. No shortcuts.
