About Tancrède

Industrial engineering graduate, then software and network engineering, I have acquired 20 years of solid experience in very diverse companies (start-ups, SMEs, and multinationals). My business knowledge in public service, industry, banking/finance, tourism, and e-commerce will allow us to understand each other effortlessly.

You can choose a turnkey software solution. Depending on the needs, projects are handled in their entirety or only on certain phases such as training, consulting, needs analysis, design, development, infrastructure, support, and maintenance.

We start by defining your objectives in terms of cost, quality, deadline, and features. Then, projects are managed agilely, with short cycles. Each significant iteration is presented to you to best meet your needs.

For a complete application need, I offer my Fullstack skills (user interface + backend). This simplifies project management and allows you to reduce overall costs.

For more specific needs, I offer my technical expertise in open-source architectures and languages/frameworks: Java, C, PHP, Bash (UNIX / Linux), Angular, Spring, Docker, IoT, etc...

Looking forward to meeting you!
