PROFILE

Alex Kolosov

Worked on the nekromant322/OverMoney repository to deliver a Payment Service core, focusing on Kafka-based transaction processing, Prometheus monitoring, and containerization using Docker and Helm. Implemented end-to-end deployment automation with Kubernetes and CI/CD pipelines, ensuring environment-specific configuration and integration with Argo CD for reliable rollouts. Developed a cross-service Subscription Status feature, introducing a REST endpoint, asynchronous messaging via Kafka, and Telegram bot integration, with built-in fallback for Kafka outages. Enhanced operational resilience by refining vault-based secrets management and expanding test coverage with Kafka mocks and deployment tests, resulting in improved stability, observability, and repeatable deployments across environments.

May 2025 highlights for nekromant322/OverMoney focused on delivering a robust Payment Service and expanding cross-service subscription capabilities, with strong emphasis on deployment automation, observability, and security. Key work included shipping the Payment Service core (scaffold, Kafka-based transaction processing, Prometheus metrics, containerization), end-to-end deployment via Helm/Kubernetes and CI/CD, and environment-specific config. Delivered Subscription Status across services with a new REST endpoint, Kafka-based messaging, and Telegram bot integration, plus a built-in fallback when Kafka is unavailable. Updated orchestrator admin access to include Megokolos. These efforts stabilized payments, improved operational resilience, and accelerated feature delivery across environments. In addition, test scaffolding evolved with Kafka tests, mocks, and deployment/test adjustments, and deployment/configuration refinements (vault values, Argo CD integration, and env-specific deployments) contribute to reliability and repeatability.
