- Participated in the entire software development life cycle, from gathering requirements and closely collaborating with domain experts to deployment by implementing DevOps practices such as containerization using Docker and Docker Compose and CI/CD with Jenkins and GitHub Actions.- Developed and maintained high-performance server applications using Python and technologies such as Django and FastAPI.- Worked on database normalization and denormalization, designed schemas, optimized queries, and ensured data security.- Conducted testing and debugging of code, including unit testing and test automation using pytest and unittest.- Refactored legacy code, significantly improving application performance.- Participated in task planning and estimation in Jira. Conducted code reviews.Significant Achievements:- After denormalizing tables and improving queries (both through ORMs such as Django ORM and SQLAlchemy, and in SQL) in PostgreSQL and MySQL, I reduced the system response time by 90%.- Created a personnel management system for my company, automating numerous processes such as employee attendance tracking, a module for surveys and feedback, payroll management, and other functions. As a result, I increased personnel management efficiency by 40% and reduced processing time by more than 60%, which contributed to significant optimization of business processes.

- Developed and enhanced server applications using Python with Django, DRF, and FastAPI according to project requirements.- Participated in database analysis and design, as well as executing queries and modifying data structures.- Conducted testing and debugging of code, including unit testing and test automation using pytest and unittest.- Refactored legacy code and participated in task planning and estimation in Jira.Significant Achievements:- Covered over 80% of the code in the project with tests before updating libraries and their dependencies (Django, DRF, gunicorn, celery, etc.), which simplified and accelerated this process.- Implemented caching using Redis, significantly speeding up the server application's response time.
