Hi!

I'm a full stack software developer with 10+ years of hands-on experience with Ruby on Rails and Javascript. I’ve worked across the spectrum: early startups, high-growth scale ups, and most recently, a large corporate product with a huge Rails monolith and even bigger DB. On the FE side I've worked with a range of libs and frameworks, starting with raw JS a long time ago all the way to Svelte.js more recently.

Have a look at my LI and if you think you're building something where I could help, let me know!

Full stack engineer focused on rapid prototyping and MVP delivery. I lead architecture and delivery for AI powered web platforms, integrate modern LLM APIs into React and Node, and ship production systems on serverless and edge infra. Recent work includes replatforming a FTSE 100 with a Next.js 15 stack and headless CMS, plus turning an AI video product from MVP into production with CI and testing. I improve developer experience with monorepos, automated quality gates, and strong observability. Happy to own greenfield builds or unblock gnarly legacy systems.

Past work includes agentic workflows, eval pipelines, prompt frameworks, GPT-powered tools, and full-stack AI products.

I prefer working directly with stakeholders. Big fan of startups.

About Me:

I'm a full-stack developer with a focus on building entire products, not just features. Since 2018, I've been helping startups and founders turn ideas into reality. I'm comfortable owning the whole stack, from provisioning AWS resources to polishing the front-end.

One of my recent projects involved building a USMCA compliance tool from scratch. I took a manual, spreadsheet-heavy process and turned it into a web app that provides a go/no-go qualification in under a minute. The stack was Python on AWS Lambda, DynamoDB, and React.

I also enjoy working with a lighter-weight stack and recently built my own SaaS product (a time-tracker for freelancers) using Django, HTMX, and AlpineJS.

I'm looking for clients who need a reliable, senior-level engineer to build robust solutions to complex business problems.

Send me an email with your needs and I'll reply to schedule a quick 15 min call.
