Freelancer profile translated to English.
Back to original languageAbout Jules
I design and develop tailor-made web applications (SaaS, business CRM, automation tools, analytics tools...) from architecture to production deployment.
My approach: understand the business need before writing a single line of code. Each project begins with an analysis phase to identify the real problems to solve, the processes to automate, and the necessary integrations. No templates, no generic solutions, I design tools tailored to the client's context, that integrate into their existing workflow and evolve with their business.
I work autonomously on the entire cycle: scoping the need, technical architecture, front-end and back-end development, database, third-party integrations, deployment, and maintenance. A single point of contact from start to finish, direct communication, and transparent follow-up.
Several projects delivered and in production, used daily by my clients. Two-time winner of national hackathons: 1st / 1000+ at Coding Battle 2025 (algorithmic geometry, C++) and 1st / 850 at Winter Is Coding (combinatorial optimization).
