Summary
Over a five-year period during university and external training, I collaborated with peers to study Java, Android, and Spring-based backend server development. I further consolidated my learning by teaching the material to my peers and documenting it comprehensively.
At Alti-Mobility, I excelled as a Backend Developer, enhancing system performance by implementing microservices and caching strategies, which notably improved scalability. My expertise in RESTful APIs and strong relationship-building skills facilitated successful cross-functional collaborations. Proficient in Java, Python, and cloud platforms, I significantly contributed to our team's productivity and code quality. Additionally, I documented my work in blogs and company documents, sharing new technologies and feedback from ongoing tasks with team members through presentations.
