Building fast, clean and maintainable web interfaces
Available for CDI / CDD / Remote, Freelance
React, Next.js, Node.js and TypeScript developer focused on building modern, performant and maintainable web interfaces. I mainly contribute on front-end topics, with strong attention to execution quality, journey clarity and product consistency. My work is grounded in real projects designed to solve concrete needs and create visible impact for both users and the business. Outside of development, I stay curious through sports, music and creative environments.

A selection of recent work
Different contexts, one intention: make a product easier to understand, more enjoyable to use and more solid on the front.
- SaaS
- concept
- art direction
Human Work Force
AIs hire humans.
Satirical SaaS concept where AIs recruit humans for creative tasks, with a deliberately playful tone but a product-grade execution.
The next projects are taking shape.
Experiences designed to extend games
A selection of game mods and experiments: new mechanics, interfaces, and content built with the same attention to how people use them.
Plasma Cutter Durability
Keep the Multicutter operational for longer.
A Palworld mod that increases or freezes the Plasma Multicutter durability, with a configurable maximum resistance.
A focused quality-of-life improvement that reduces tool downtime while keeping the game's behavior under control.
- Configurable durability
- Infinite durability option
- Focused Multicutter tweak
More open creative work, between interfaces and game worlds
A more experimental part of my work, where I build Source maps, in-game GUIs, and a video game project with the same attention to pacing, readability, and atmosphere.
Source Maps
Maps shaped around pacing, readability, and atmosphere.
I build maps for the Source engine with a strong focus on flow, visual landmarks, and the feeling of exploration.
Each environment is built as a playable, readable space where circulation, contrast, composition, and atmosphere support both gameplay and staging.
- Blockout, composition, and circulation
- Visual atmosphere and landmarks
- Clear readability of volumes and areas
Smaller building blocks, designed to stay useful
More focused mini projects, built like self-contained modules: clear intent, clean execution, and a structure that stays easy to evolve.
Convert Img
Fast image conversion without friction.
A focused utility built for one simple job: converting images cleanly with a clear interface and a direct flow.
This module was designed as a self-contained building block: low visual noise, immediate actions, and a structure that stays easy to extend when new formats or options are added.
- Fast conversion
- Minimal flow
- Extensible base
A fast, structured and product-minded contribution
I contribute best in environments where an interface needs to be designed, structured and pushed forward with high standards, while keeping business needs and product priorities clearly in view.
Interfaces & flows
Designing clear, well-structured screens that make journeys easier to understand and smoother to use across desktop and mobile.
UI systems & components
Setting up reusable components, a consistent UI foundation and simple conventions to speed up delivery without lowering quality.
Front-end / API integration
Connecting interfaces to APIs and real use cases, with a clear and pragmatic Node.js layer when the project needs it.
Execution quality
Finishing the details that strengthen product perception: responsive behavior, accessibility, performance, reading comfort and visual consistency.
A clear, reliable and delivery-focused approach
Frame the need
Clarify the problem to solve, the users involved and the functional priorities so the work starts on the right foundation.
Clarify the experience
Shape information hierarchy, reading rhythm and interactions so the product feels more intuitive and efficient to use.
Build a solid foundation
Create a clean front-end structure, useful components and readable technical integration that support long-term product evolution.
Deliver with care
Validate the details that matter in production: responsive behavior, keyboard support, performance, visual consistency and robust integration.
