Fullstack, Architecture and DevOps
Fullstack Developer
Systems & DevOps
I build complete applications, from frontend to infrastructure, designed to simplify, automate and last.
Curious by nature, I enjoy exploring the full spectrum: architecture, security, observability, DevOps. What drives me is understanding how things work under the hood and building them with care.
Building systems, not just features.
I build modern web interfaces, but I also care about what happens behind the scenes: architecture, security, deployment and observability.
My goal is to understand and own the full technical stack.
What sets me apart
Systems thinking
I don't just build interfaces. I think about the whole system: frontend, backend, infrastructure, monitoring and SEO. I also optimize performance and user experience so every site is fast, accessible and well-indexed.
Security & robustness
Security is a priority for me: authentication, token management and system hardening.
Automation
I look for ways to simplify and automate processes to reduce friction and save time.

Under the hood

A learning platform dedicated to Vue and Nuxt. The site also includes a course explaining how LetsLearn itself was built.
Optimisation

My philosophy
When I build something, I always think about how to simplify usage, automate repetitive tasks and make tools more accessible. I aim to design systems that are robust, readable and built to last.
