The project consisted in creating a credit application for individuals in foreign markets. Responsibilities: * Development and implementation of new functional modules that provide integration with external services, such as BPM and mobile operators. * Refactoring and updating existing code and service architecture, including reworking of obsolete service architecture. * Solution and prompt response to accidents, including monitoring, analysis of incidents, development of action plans to prevent them in the future. Achievements: * Developed a functionality to cache OTP messages using Redis, which resulted in a 30% increase in system performance. * Implemented custom exceptions for the payment service. This has improved the accuracy of third-party error handling, significantly improving service quality and increasing efficiency during issue resolution. * Implemented logging in 5 services of the project. This step significantly facilitated troubleshooting, increased system productivity, and prepared the project for future integration with ELK. * Covered around 20% of the team's code with automated testing using Pytest, leading to a reduction in crashes in production. Stack: Python 3, FastAPI, Swagger, Rest API, Postgresql, MongoDB, Redis, Asyncio, aiohttp, Linux, Docker, GitLab, Jira, Confluence, Zabbix, Grafana, unit testing, Pytest, Django.

The project consisted in creating an automated system to generate work programs for various disciplines, which uses available data to optimize efficiency. Responsibilities: * Development and design of server architecture for web applications in Python. * Deployment of the project on a private server to provide secure access to stakeholders and users. * Improve server systems by adding new functions to support project requirements. Achievements: * Created an optimized database schema, ensuring fast and reliable storage and retrieval of critical data. Improved database performance by 20%, leading to a reduction in response time to user requests. * Developed and implemented new functions, expanding the capabilities of the server system to support the project requirements. * Secure server configuration guaranteed using advanced data protection methods. * Developed and optimized SQL queries, ensuring high performance and scalability of the database. * Agile development methodologies applied for effective teamwork. * Covered around 60% of the team's code with automated testing through unit testing, which led to a reduction in crashes in production.
