In May 2025, Megokolos developed and deployed core payment and subscription features for the nekromant322/OverMoney repository, focusing on robust backend architecture and operational reliability. They built a Kafka-driven Payment Service with Prometheus monitoring, containerized via Docker, and automated deployments using Helm and Kubernetes. The work included a new REST endpoint for cross-service subscription status, asynchronous messaging, and Telegram bot integration, with fallback logic for Kafka outages. Megokolos enhanced test coverage with Kafka mocks and refined environment-specific configurations using Argo CD and Vault, resulting in improved deployment repeatability and system resilience across multiple environments without introducing new bugs.

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.
