In a previous role, I led the integration of a legacy CRM system with a new ERP platform. The primary challenge was the disparate data models and the need for real-time data synchronization. I implemented a middleware solution using Apache Kafka for message queuing and developed custom ETL scripts to map and transform data between systems. This approach ensured minimal downtime and seamless data flow, despite the complexity of the integration.

I follow a structured approach to testing and debugging. Initially, I conduct unit tests on individual components to ensure they function correctly in isolation. Next, I perform integration testing to verify that the components interact as expected. For debugging, I use logging frameworks to capture detailed error messages and trace data flow. Additionally, I employ monitoring tools to continuously track system performance and identify any anomalies post-deployment.

Ensuring data consistency involves implementing robust validation checks at both the source and destination systems. I use database transactions to maintain atomicity and consistency during data transfers. For data integrity, I apply checksum algorithms to verify data accuracy and employ error-handling mechanisms to manage and recover from data corruption. Regular audits and reconciliation processes are also part of my strategy to maintain high data integrity.

I stay updated by regularly attending industry conferences, webinars, and training sessions focused on integration technologies. I also follow leading tech blogs, forums, and publications to keep abreast of emerging trends. Additionally, I engage in continuous learning through online courses and certifications. Participating in professional networks and collaborating with peers helps me exchange knowledge and stay informed about best practices in integration development.

I have extensive experience in designing and managing APIs using tools like Swagger and Postman. I follow RESTful principles to ensure APIs are scalable and maintainable. My approach includes defining clear endpoints, using versioning to manage changes, and implementing security measures such as OAuth2 for authentication. I also use API gateways to manage traffic, enforce rate limits, and monitor API usage. This ensures that APIs are robust, secure, and easy to integrate with various systems.
