Aliexpress is a global marketplace. Team are responsible for localizing stores that were previously overseen by China and recently we launched a new tool called "promo pages," which are curated pages featuring a specific selection of products.- Contributed to the platform library in Kotlin, enhancing monitoring by adding logging for grpc and http calls with configurable options and implementing easy filtering using labels in Loki (Grafana). Also addressed bugs.- Launched the "Stores" service in Kotlin and Spring Boot, transitioning it from a closed-source project managed by a team in China. This move ensured data accuracy, including product prices, and reduced dependency on China. Introduced Redis caching for faster responses.- Developed a Golang proxy service between our microservices and Chinese services for store subscriptions. Created Kotlin API endpoints for data transmission to the frontend, involving 20 calls to various services through GRPC and HTTP.- Expanded functionality of an existing Golang and PostgreSQL microservice, enabling data segmentation among users based on different criteria. Added a preview feature for operators to test changes in the production environment before release and introduced a payment feature for sellers based on tracked data through Kafka.- Improved the application migration process by separating it into a dedicated CI/CD job for a Golang microservice. Replaced string concatenation with the Squirrel framework for forming SQL queries.- Took the initiative to enable local deployment of all microservices, significantly improving debugging and development processes. Implemented a more appropriate Fibonacci-based task estimation scale for improved sprint execution and reduced task transfers.- Established a mandatory practice of writing tests for code, resulting in a test coverage increase from 0% to 90%.- Created multiple Grafana dashboards and set up Prometheus alerts.

- Successfully launched a Golang microservice with PostgreSQL and an admin panel for operators. Features included scheduling, sorting stories, and tracking paid stories. Utilized Liquibase and golang-migrate for SQL migrations. Introduced new tools for user notifications about sales and promotions.- Enhanced product variety and categorization in the recommendation feed using Kotlin. Developed a product carousel and a universal configuration for content display, optimizing performance with Redis to reduce search operations.- Reduced backend engineer onboarding time from two weeks to two days. Authored helpful articles and guides for access, testing, and troubleshooting. Simplified time-off and birthdays tracking for team members with a calendar in Confluence.
