Back to original languageAbout Baedaar
About me:
Final year engineering student at ESIEA (Software Engineering), I have 3 years of experience in a work-study program on complex back-end architectures—first at Iperia-HAVAS (ekino), then at SNCF Connect where I am currently working on a European-scale transport data management system.
My background is unusual: before computer engineering, I obtained a degree in Human Biology and Health Technologies, which gives me a real sensitivity for medtech, digital health, and data fields—and an ability to understand complex business contexts beyond the code.
What I do:
Back-end development in Kotlin & Java (Spring Boot, REST APIs, Feature Toggles, Gherkin/BDD)
Data processing and normalization via complex mappers and multi-service integration
Cloud & DevOps: AWS, GCP, Docker, GitLab CI/CD pipelines
Legacy Java → Kotlin migration, SQL optimization, ElasticSearch integration
Why me:
Accustomed to demanding environments (large accounts, monorepo, multidisciplinary teams), I am comfortable in English (C1 — academic experience at the University of Michigan, Dearborn) and quickly operational on ambitious projects.
Available for short freelance assignments remotely or in Paris.
