Software developer, startup founder, and creative builder.

I'm Jack, a software developer and engineering leader based in Preston, UK. I specialize in building robust, scalable systems and have years of experience delivering production-grade software across startups and established platforms. I'm currently working full-time as a technology lead, but I'm also available for select freelance projects where I can bring technical depth and practical execution to the table.
