About Guillaume

Having worked for nearly 10 years in refrigeration, I decided to venture into creating applications dedicated to this sector. Attracted by the countless possibilities offered by this discipline, I finally chose to pursue a career in development.

I am a specialized Ruby on Rails / ReactJS developer. Thanks to my professional background as a commissioning engineer and salesperson, I have developed a strong aptitude for problem-solving and possess a keen understanding of client needs.

I am willing to work on existing projects or create a website or mobile application from scratch. I am motivated by complex challenges and always strive to deliver superior quality content, carefully prepared and tailored to the client's specific needs.

I also have experience and skills in creating databases from web scraping.

Please note, however, that regarding web scraping, it is essential to first ensure that the technical and legal requirements of the mission are feasible. Do not hesitate to contact me if you have any questions or wish to discuss your project in detail!

Experience

  • Kwot'z
    Developer
    SOFTWARE PUBLISHING
    December 2022 - Today (3 years and 6 months)
    Creation and development of an application to connect refrigeration and air conditioning professionals with their suppliers.

    The idea for this application was born from the discovery of a recurring problem: the lack of time for professionals to handle their price or sizing requests, and the lack of information provided to their suppliers.

    The back-end of this application was developed using Ruby on Rails and the front-end in REACT js.
    It was necessary to use Mailjet for email sending and AWS for storing supplier quotes.
