Technical Lead

Tools: and Tech: Apache CXF, Core Java, Spring, Oracle, Apache HTTPD, nginx, JSON, XML, Unix, Maven, Jenkins, Adobe AEM, SABA

Responsibilities:

• Requirement gathering, analysis, design and development of these services.
• Architecture of services that need to be exposed, the one that need to be invoked and the required data transformations to successfully achieve provisioning of different type of users.
• Expose a variety of services for the learning application.
• Design and build heavy processing asynchronous services like video and image rendition creation, break them into subparts and upload them to third party asset services.
• Design and develop these web services with security, proper exception handling and logging to trace the requests end to end.
• It also involved placing proper monitoring not just on services that were exposed but also the ones that were invoked that help identify the issues in the application immediately. Also right set of configurations helped in maximizing uptime despite possible latency in the services that were invoked.
• Improve logging, use splunk to create dashboards that help track the system as well as the functional KPIs and find out the reasons for issues like site slowness and DOS attacks.
• Provide support to the system in Production environment.
