Hi! I'm Luke, a Frontend & Full-Stack Engineer with 3 years of experience building scalable, high-performing web applications. I'm based in Montpellier, France.
I specialise in data-heavy dashboards and reusable component libraries for financial risk management, working across the stack with React, Next.js and TypeScript on the front end and Golang, Python and Docker on the back end. I care deeply about performance, maintainability, and clean, intuitive UI.
I'm always eager to learn and explore new technologies to stay ahead of the curve and tackle complex challenges. Whether it's refining existing systems or building something from the ground up, I thrive on creating efficient, well-structured digital solutions.

Freelancer Marketplace Platform
For my final-year project in Advanced Web Development, I built a freelancer marketplace platform designed to connect clients seeking specialised services with freelancers who have the skills and expertise to deliver them. It streamlines the freelancing experience, giving freelancers a place to showcase their skills and clients a convenient way to find and collaborate with them.
Tutoring Academy Website
For my first freelancing project, I rebuilt the business website of my high-school tutor. I learnt how to manage a project and maintained clear communication with the client to ensure things went smoothly. The project was deployed using Vercel and I used OVH as the domain name registrar.
