About Dov

Always attracted by innovation and technological challenges, I am a backend developer with over 6 years of experience. After graduating from École 42, I worked on innovative projects in various sectors, from online advertising to mobile application publishing.

My career has allowed me to develop very strong expertise in Go, my preferred language. I have also had the opportunity to use other languages such as Scala, Node.js, C, and C++ for different projects. I am also proficient in Docker, and AWS and GCP cloud services.

I offer custom backend development services, covering a wide range of needs from the design and implementation of microservices to the integration of various technical solutions, as well as optimization in high-traffic environments and the setup of robust CI/CD pipelines. All my deliverables are accompanied by tests and complete documentation, integrated with the tools you already use. When I work on new features, I make sure to adapt to the existing codebase to maintain uniformity and ensure good code maintainability.

I enjoy challenges and whatever task is assigned to me, I always succeed in completing it. Furthermore, I am an excellent communicator, which allows me to work effectively in a team and facilitate collaboration on projects.

Curious and oriented towards solving complex problems, I enjoy working in agile and collaborative environments. Whether you need to refactor an existing application or develop a new solution from scratch, I am ready to bring my technical expertise and passion for innovation to your project.

Contact me to discuss your needs and discover how I can contribute to the success of your projects.
