Tinkoff | Microservice application for tracking updates on StackOverflow and GitHub

• Telegram Bot on Java using Spring Boot interacts with users. Telegram Bot API supports commands, finite state machines using Spring State Machine, and notification modes
• Scrapper multithreaded scheduler on Spring Boot with custom HTTP clients on Spring WebClient for GitHub and StackOverflow APIs, and with Resilience4j retry policy (Retry, Circuit Breaker)
• Asynchronous interaction between Apache Kafka and HTTP services. Dead Letter Queues and caching are implemented in Redis using Spring Data Redis.
• Database access is configured using PostgreSQL and JPA/Hibernate, and Liquibase is used to manage migrations.
• Prometheus is configured to collect JVM metrics, RED metrics collection is configured in Prometheus, with visualization using Grafana and Micrometer.
• Services are in isolated Docker containers with Kubernetes orchestration and local launch with Docker Compose. Swagger is used for documentation.
• The code is covered by tests using Testcontainers for reliability.
