Worked on the SoftwareAG/c8y-docs repository to enhance the reliability and observability of the Apama-ctrl microservice. Addressed a bug where negative values for client.numClients could disrupt microservice communication by implementing defensive input handling in Markdown-based documentation. The solution defaulted negative inputs to 1 and logged a warning, reducing the risk of downstream failures and improving maintainability. Documented the change in the project changelog to support future audits and transparency. Demonstrated strong skills in documentation and input validation, focusing on system resilience with minimal code changes. The work emphasized careful attention to defensive programming and robust error handling practices.
