Senior Backend Developer at CodaBene (Paris)

CodaBene helps manufacturers and retailers reduce food waste and strengthen product traceability by digitizing the management of expiry dates and batch numbers.

As a Senior Backend Developer at CodaBene in Paris, I was responsible for designing, implementing, and maintaining the monitoring system, as well as building scalable features and optimizing queries using Django, Celery, RabbitMQ, Python, and Git. During my time at CodaBene, I successfully tackled several key challenges:

• I fixed a performance issue on a main query, saving the company valuable time and preserving its reputation during the testing phase.
• I created a new model to help the asynchronous part of the project treat requests synchronously, ensuring data accuracy and consistency.
• I proposed a new implementation based on date format that helped us introduce a new feature without changing the existing logic, saving months of testing and debugging.
• I helped onboard new team members more quickly by implementing a new architecture for the project that reduced the time it takes to create a first pull request to just two days.
• I played a key role in the company's recognition, including winning the 2021 Trophées LSA award and the ESSEC prize for our collaboration with Enseignes Casino.

In Year 1 of my role, I optimized queries, rebuilt existing features, and helped take the project from POC to production, maintaining the same quality of performance as we scaled from 40 clients to over 700 clients. I also designed and modeled the monitoring system, collected data from different sources (Csv, Excel, and external APIs), and implemented a reporting system (emails, dashboard) and an analytics system (data science).

In Year 2, I continued to expand my expertise by automating resource scaling, using ElasticSearch, implementing CI/CD, using Docker, achieving high performance on a database of approximately 300GB, and architecting the project into single responsibility files.

Overall, my experience at CodaBene demonstrates my expertise in backend architecture and design, as well as my ability to solve complex problems and deliver high-quality results in a fast-paced startup environment.
