About Frédéric

Developer for over 25 years, I offer my services in the design anddevelopment of applications, tools, or components**. Experienced in **Javaand **Typescript**, I am a "full stack" developer, ready to work on the frontend, backend, as well as tools or component libraries.

I can also act as a **consultant**, at all stages of a project, from initial needs analysis to diagnosis during the maintenance phase. While this type of service often concerns technical aspects, I also enjoy getting involved in more functional analyses.

A good **document writer**, I don't shy away from expressing my abilities in producing study reports, specifications, architectural documents, technical documentation, training materials, or articles (in French and/or English)...

Despite my past as a manager (CTO and project manager roles), I no longer offer my services in team leadership or activity monitoring.

I work in any business domain, unless the mission requires specific expertise in that area: I have already worked in industry, retail, healthcare, finance, insurance, administration, software publishing, human resources, and education. I am familiar with large corporations as well as SMEs and startups.

Today, my "ideal technical stack" would revolve aroundJava**, **Quarkus**, **AWS Lambda**, **MongoDB Atlasfor the backend andTypescriptandAngularfor the frontend. However, due to my experience, I can work on various technical environments and I adapt easily to new technologies.

I invite you to visit my personal website at fredtech.pro to learn more about my profile, my background, and my services.
