What I'm looking for

I'm looking to continue building secure, high-performing digital and contact center applications using Agile Java development, APIs, and collaborative delivery practices.

At Black Box Limited, I built and deployed backend digital and contact center applications for Xiaomi, TCS, Banglalink, and Walaa Insurance.

I integrated secure RESTful APIs and SOAP web services, replaced direct database dependencies with centralized APIs, and developed complex application logic to improve performance, connectivity, and maintainability. I also led System Integration Testing and User Acceptance Testing and provided post-go-live monitoring and debugging support for stable deployments.

I've grown from Graduate Engineering Trainee to Senior Engineer, working with Java, Spring Boot, microservices, Avaya Interactive Response systems, and Agile development.
