What I Do

I write great software and I inspire others to do so as well.

I've worked in corporate teams and start-ups, yet they're all linked by the desire to have software that they can invest in for the long-term. With a decade of experience, my software is written with future maintainability in mind. I weed out technical debt and build in strength through solid principles rather than what is just the current buzzword.


Great software doesn't just happen. It needs to be carefully considered. What are you trying to achieve? What resources do you have available? Who is going to consume it? I've got plenty of experience in knowing how best to start long-term software project.


Do you need an extra pair of skilled hands? I've a decade of experience in building high performance software and leaving it in a position where others can continue where I have left.


Sometimes the only help you need is skilling-up your existing developers. I've run many workshops over the years, for both newbies and experienced developers who want to switch over to the NodeJS world.

What People Say

Danielle Evans
Simon was great to work with - he brought a wide range of skills to each project and was quite capable of looking outside those skills and learning new ones if the situation called for it. An enthusiastic, flexible and professional developer.

Simon was a great help to the digital team during his 7 months at Torpedo. He learnt our systems and processes quickly, hit the ground running on his projects, was happy to work overtime on rush projects and set us up with Linux cloud hosting. I would happily work with him again in the future.

    Developer on both the front and back-end to build an automated pension advice system for LV=. The API generated the ~150 question schema and calculated the advice based on the answers. The front-end was an AngularJS app that managed the user experience, generating the forms and there were plenty of graphical representations of the data once the advice was generated.
