Back to original languageAbout Steffy
Full stack developer and IT project manager, I support companies and entrepreneurs in the design and development of tailor-made, reliable, scalable digital solutions aligned with their business challenges.
With over 10 years of experience in web and software development, and a Master's degree in Mathematics and Computer Science with a specialization including artificial intelligence, I have a rigorous, structured, and results-oriented approach. I work on projects ranging from creation to optimization or redesign of existing applications.
I manage projects end-to-end: needs analysis, architecture definition, front-end and back-end development, API and AI tool integration (chatbots, automation, assistants), deployment, and maintenance. I pay particular attention to code quality, performance, and user experience.
My goal is to simplify the technical aspects, propose concrete and sustainable solutions, and establish clear, fluid, and professional collaboration with my clients.
