Configuration Management and Work-Order Platform

Manual network configuration changes across distributed devices introduce human error and prolong provisioning times. Changes need to be tracked, validated, and traceable from request to completion.

Modular Spring Boot microservices expose REST APIs for configuration and work-order workflows, validate configuration templates, orchestrate multi-step work orders, and audit every deployment state, backed by relational and wide-column storage and deployed on Kubernetes.

Backend development on microservices and their deployment. This was professional work for an employer.

• Java
• Spring Boot
• MySQL
• Cassandra
• Docker
• Kubernetes
• Maven

• Keep services small with clear API contracts, separating template rendering from device execution.
• Choose the data store per access pattern rather than using one for everything.
• Use a transactional outbox pattern to keep configuration services and audit logs reliably in sync.

• Recovering gracefully from transient transport failures mid-workflow.

  Idempotent configuration APIs and explicit, resumable state transitions.

• Idempotency in network configuration APIs is crucial for recovering gracefully from transient failures.
• Database constraints and application validation serve different purposes; use both.
