I developed a Node.js microservice application that parses notifications from Telegram groups using a client. It includes a Telegram client management system, a PostgreSQL database with Prisma.io as the ORM, and deploys with PM2 for production. User authentication is done via OAuth with Google and GitHub. The application features a parsing service, a REST API with Swagger for keyword-based data retrieval, sorting, and filtering. Users can add custom groups, exclude specific ones, and manage their clients.

The project comprises a Node.js microservice for parsing Telegram notifications using a client and storing data in PostgreSQL via Prisma.io. PM2 is used for production deployment. OAuth integration with Google and GitHub handles user authentication. The application includes a parsing service, a REST API with Swagger, and a GraphQL-based administration panel for user interactions. Users can set keywords, retrieve messages, and manage their Telegram clients. Custom group addition and exclusion are supported.

Task: The project's objective is to enable users to retrieve relevant information by associating keywords with their profiles. Messages matching the keywords are retrieved from the database. Users can manage their clients, add custom groups for parsing, and exclude specific groups. The GraphQL-based administration panel serves as the REST API, facilitating user interactions and efficient management.

The project enhances productivity by providing personalized data retrieval, sorting, filtering, and customization options. The administration panel streamlines user interactions, making it easier to manage the application.

E-commerce Platform built using the Microservices Architecture Style. Each core business capability is implemented as an independent microservice, allowing the system to be scalable, resilient, and easy to maintain.

MAJO - Microservice Atomic JObqueue

Small Go microservice that prints animal sounds and emojis.

Saga choreography pattern for managing distributed transactions across microservices using asynchronous events. Each service participates in the saga by emitting and responding to domain events, eliminating a central orchestrator. The project includes multiple cooperating services, event definitions, and examples of compensation flows to handle failures in event sequences.

Saga pattern with an orchestrator for managing long‑running distributed transactions. A central coordinator (orchestrator) directs microservices through a series of steps and compensation actions when necessary. It’s a learning lab designed to contrast with event‑driven choreography, show transaction boundaries, and explore rollback strategies in distributed systems.
