About Nicolas

Hello, I'm Nicolas, a full-stack developer specializing in cloud, cybersecurity, and data.

At PocketResult, I improved a key application by adding a permission management system with SpiceDB, a task management module, an Excel/CSV file import, and a document management system. I also resolved a security counter-audit and fixed detected vulnerabilities, contributing to the validation of the client contract.

At Rushour, I designed, developed, and maintained a crawler deployed in 8 countries to collect data on UberEats, Deliveroo, JustEat, and Glovo. This system, equipped with integrated geolocation, supported the sales team. I also worked on the React Native mobile application, particularly on compatibility with specific printers, bug fixing, and optimizing existing integrations.

Previously, I have 2 years of experience in cybersecurity, where I automated deployments with Packer, Terraform, and Ansible, and developed Python microservices with 95% test coverage.

Self-taught, I develop applications or systems in Node.js and I am learning about blockchain, AI, and cybersecurity.

A graduate of 42 Born2Code, I have a solid foundation in C and systems development.

Key skills: Typescript, Nest.js, Cybersecurity, Python, AWS, Microservices, Graphql, React.

Experience

  • POCKETRESULT
    Freelance Developer
    August 2024 - June 2025 (10 months)
    I contributed to the creation of an application by adding key features such as a permission management system with SpiceDB, a task management module, and an Excel/CSV file import tool. I also participated in a security counter-audit by fixing identified vulnerabilities and integrated a document management system. Finally, I redesigned data processing to enable the display of clear and interactive charts. These developments allowed for the validation of the client contract, fully meeting their functional and technical expectations.

    I worked on the email management interface used in the machine learning pipeline, particularly to allow users to validate or correct AI-proposed results when they are erroneous. This interface covers data processing, model training, and evaluation stages. I also integrated the reading of attachments to broaden the range of information sources usable by the system.

Education

  • Alumni
    42
    2021
    Pendant ma formation à 42, j’ai mené plusieurs projets techniques, principalement en C, mais aussi en cybersécurité. Boot2Root était un challenge orienté sécurité, basé sur l’exploitation de failles OWASP, où l’objectif était d’obtenir les droits root sur une machine virtuelle. J’ai aussi développé ComputorV1, un résolveur d’équations du premier et second degré capable de parser des chaînes complexes. Avec 42sh, j’ai recréé un shell complet. J’ai également réimplémenté des outils système comme ls avec ft_ls et printf avec ft_printf. Le projet fdf m’a permis de générer une carte topographique en 3D, et libft m’a servi à construire une bibliothèque de fonctions essentielles utilisées dans l’ensemble de ces projets. J’ai aussi suivi la branche Reverse Engineering, composée de quatre projets avec une dizaine d’exercices. Le but était d’analyser des binaires avec un débogueur, repérer des failles comme des buffer overflows, puis comprendre et détourner le comportement du programme.
