Technical Lead/Architect

Responsibilities:

• Architected a suite of Spring Boot / Batch applications to periodically fetch reposession data from a third party vendor site, and pass it to our monolithic application in a resilient way using RabbitMQ and Enterprise Integration Patterns.

The project became a model for the company.
