The software architectural learning course "Code like a Programmer, Think like an Architect" has been produced.

- Designed a new audit logging system to improve tracking and compliance.- Developed the design and implementation plan for transitioning a monolith application to a microservices architecture, enhancing scalability and maintainability.

- Designed the architecture of applications and their interactions with each other.- Identified and resolved complex technical issues (distributed deadlocks, data-dependent bugs, etc.).- Improved code quality through mentoring team members and planning refactoring.- Enhanced system responsiveness and stability by implementing cutting-edge approaches.- Led the backend team, managing responsibilities such as hiring, onboarding, and mentoring.

- Developed applications using Django REST Framework and FastAPI.

- Led a major architectural project of big data analysis platform improvement, differentiating between "heavy" and "light" computations for optimal performance. Introduced asynchronous intercommunications, enhancing modularity and reusability. These changes resulted in a significant increase in processing efficiency and improved user experience.- Spearheaded the design of a comprehensive authorization system based on the Role Model. This system was tailored to handle complex user hierarchies and access control scenarios, ensuring robust security and streamlined user management.- Engaged in research and development for a pioneering graph-structured data handling, storing, and analysis system. - As a mentor to the backend development team, I focused on enhancing code quality and problem-solving skills. Under my guidance, team members developed more efficient code, reducing bug rates. I also facilitated knowledge-sharing sessions that led to improved team collaboration and individual skill enhancement.

- Conceptualized and built a database-less, multiprocessor ETL system that adheres to ACID principles from scratch. This innovative approach to ETL processing significantly increased data integrity and processing speed, handling large-scale data transformations with high efficiency.- Rebuilt big data analysis Platform's REST API using asynchronous approach.- Led the development of a highly modular API gateway using Go, designed for optimal performance and scalability. This gateway serves as a critical component in our system architecture, efficiently managing traffic and providing enhanced security features.

- Developed the server component of a data collection system utilizing handheld terminals for warehousing data collection. The server component is designed for efficient, asynchronous retrieval of data from numerous terminals.- Designed and developed a production cost-calculating system.- Refactored, enhanced, and further developed the office equipment accounting system.
