Back-end Developer in London, United Kingdom

Stack Overflow is a Q&A site for programmers. It is the number one destination for any programmer who is stuck and needs answers and is in the top 40 most used sites in the world.

I spent five years working in the core team at Stack Overflow - working on the Q&A engine and performance and features on the site.

For ASOS, I wrote an automated image resizing application based on their proprietary image editor workflow. This included live previews and curated sets of pre-selected editing options.

This work was estimated to save £90,000 per year in increased image editor productivity.

I developed all video and audio processing routines for the Halifax Save the Children Christmas choir campaign.

This web app allowed customers of the bank to record themselves singing Christmas carols, then select other friends and customers that have also recorded themselves.

The application then composited these videos and audio streams to produce a single video where the selected people were singing together.

I designed and wrote a code generator that produced JavaScript, TypeScript, and Solidity code based on a JSON description file.

This was needed to ensure the product front end and the Ethereum blockchain were packing and unpacking transferred data in the same way.

The code generator was a cornerstone in getting third-party game creators onto the FunFair platform.
