2. Designed and developed some Core APIs and flows using ejb etc. for Corporate Workflow Manager Framework (COMS). Also improved the
performance and monitoring for COMS.
3. Prepared OLTP server for PIN change, Efund, MasterCard certifications, very expensive simulators and proxies for internal network handling like for
jordan and i2c related banks.
4. Developed for a billing system with distributed Infinispan cache topology and Dynamic Rule Engine for validation, information extraction, etc.
Frontend Services:
1. Designed, and developed some administrative apps to support some backend services that are extensible to adapt new requirements as single source
for all concerns e.g. BPMN framework activiti administrative console.
