About Killian

Junior full-stack developer in training at the 42 Paris school, I offer my services for web development, automation, application maintenance, and technical support missions.

Thanks to my project-based training, I have developed solid foundations in C, C++, Linux, network programming, process management, Docker, and technical problem-solving. I have notably worked on projects such as Minishell, ft_irc, Cub3D, Push Swap, Philosophers, and Inception.

I am now focusing on full-stack development with Python, React, and Go, in order to be able to work on modern web applications, APIs, internal tools, and automation scripts.

I can help you with missions such as:
- creation or improvement of a web application;
- bug fixing;
- frontend integration;
- Python script development;
- automation of repetitive tasks;
- setting up or fixing Docker environments;
- maintenance and improvement of existing projects.

I am available for short or one-off missions, ideally remotely, in parallel with my training at 42.

Serious, autonomous, and accustomed to learning quickly, I easily adapt to the needs of the project and the technologies used.
