Back to original languageAbout Yassin
Software Engineer specializing in TypeScript, I work on end-to-end web and mobile projects — from NestJS APIs to React Native applications, including infrastructure and CI/CD pipelines.
For over 3 years at DiamPark (HealthTech), I have been designing and maintaining a medical mobile application for Parkinson's disease patients, using a React Native, NestJS stack and a clean, domain-oriented architecture. This experience has given me a rigor in code quality, reliability, and health data security.
I also provide technical training in schools and training centers (software architecture, DevOps, Agile), which gives me the ability to simplify and document without sacrificing precision.
I am looking for assignments where technology has a real impact — products in production, demanding teams, high-stakes domains.
