✔ Developed a new microservice in Golang for working with ERID, enabling the company to comply with the legal requirement for mandatory advertisement labeling. ✔ Developed a new microservice for sales limiting to prevent a single buyer from purchasing all units of a product. ✔ Implemented partitioning, optimized Postgres database operations, and added caches in the microservices, resulting in a 15% improvement in microservice response time. ✔ Maintained a Symfony monolith by removing unnecessary functionality and adding new features, which improved response times by 100-200 ms, with acceleration reaching 1-2 seconds in some regions of the Russian Federation. ✔ Maintained the internal admin panel (used by all company managers) built on Laravel. All microservices had endpoints for data operations, with a user interface in the admin panel to interact with these endpoints. After making changes or adding new microservices, the admin panel was updated accordingly. As a result, managers always had up-to-date data on all microservices from the team and could manage the data effectively.
