Experienced software engineering, on demand. Greenfield builds or existing codebases, minus the overhead.
that's me!
I've spent over a decade building software that actually works - for enterprises like Asda, Sky, and Virgin, for businesses across the UK, and embedded inside existing teams delivering for their clients. I've seen what works at every scale.
That's why KD Digital exists. Whether you're a business that needs a senior developer without the overhead of a full-time hire, or a team that needs reliable extra capacity on a client project - I slot in and deliver. I'm not here to just pump out code. I get the architecture right first, so what we build is scalable, secure, and performant from day one - not a rewrite waiting to happen.
Whether you want to build an MVP for your next big idea, need custom software to streamline operations, want to explore how AI can transform your workflows, or need a trusted partner to augment your existing team - I'm here to lay the foundations and get it done right.

Core Tech Stack
- Toby Moore Parallax"There's always the question of 'would you want them in your team?' and I would 100% want Karl in my team again."
- Peter Yeo Asda"Karl's technical expertise and collaborative approach were invaluable assets to our team. He bridged the gap between onshore and offshore engineering teams [...]"
- Kyle Thomas Doza Consulting"Karl is a great engineer and all round great guy. He worked with us for almost a year and received glowing reviews from our client. Highly recommended."
Technical design, architecture, and delivery end-to-end. I keep you in the loop without the jargon. Senior developer, not faceless agency.
I embed into your delivery team, pick up your processes, and ship under your brand - fully white-labelled. Minimal ramp-up, maximum output.
Ongoing senior capacity - standups, technical direction, mentoring juniors. I become part of your extended team. Months, not days.
Got a project mapped out, or just a rough idea to kick around? Drop me a line. No sales pitch, no jargon - worst case, you get a free second opinion.
