Back to original languageAbout Calixte
I design and develop web products from scratch: SaaS, MVPs, business tools, and AI-based features.
I can take an idea, a prototype, or a business need, design the architecture, and deliver a complete product to production.
Since 2023, I have been developing the Muzisecur platform: a SaaS for music professionals on which I have designed over twenty business services, from automatic contract generation to electronic signature, including music distribution and automation of administrative tasks.
I have notably transformed manual processes that took several hours into workflows achievable in a few minutes.
Main Stack: TypeScript, React, Next.js, Node.js, PostgreSQL, Redis, and Docker.

I had the pleasure of collaborating with Calixte on an important project for me: automating the calculation of comments for a contest I organize on YouTube and my blog. Calixte was exceptional from start to finish: professional, responsive, attentive to my needs, and proactive.
Not only did he perfectly understand the stakes of my challenge, but he also provided elegant and effective technical solutions, while respecting my sometimes ambitious deadlines. His work saved me precious time and allowed me to focus entirely on my artistic and educational activities.
Beyond his impressive technical skills, Calixte is a reliable, positive, and very pleasant person to collaborate with. I highly recommend his services to anyone looking for a serious, creative, and committed professional.
