Engineers who actually ship.

BrainCode is a London development studio founded in 2018 and based in Sidcup, Bexley. We're a tight team of senior developers who live and breathe JavaScript. From pixel-perfect front-ends to rock-solid back-ends, we write clean, tested, production code — and we ship it fast. No juniors learning on your budget, no hand-offs that drop the ball. Just experienced engineers who sweat the details and care about your results.

We build with React, Next.js and TypeScript on the modern JavaScript stack, and we obsess over the things that actually move the needle: sub-second load times, green Core Web Vitals, technical SEO and accessibility. Whether it's a marketing site, an online shop or a full web app, you get a product that's fast, secure and ready to grow — backed by a team that answers the phone and ships on time.
