Kamel C.

Intervention as a Senior Java Developer within a team of 10 people (6 Business Analysts and 4 Project Managers) on the Alerting system.

A central system for sending multi-channel notifications (SMS, App Push, Email) to SG bank clients (individuals, businesses, and professionals), with high availability.

Projects:

SecuriProd: To make production more reliable and avoid service interruptions, I developed a persistence layer in Oracle database in case of connection loss to the queue manager. As well as a replay application following specific rules for each type of alert.

And to get rid of the MQ Series queue manager, I migrated several listeners and all web services (rest/soap) to Kafka.

MSP: I developed an email routing system to the federator with Throttling and a circuit breaker (MongoDB, Kakfa, Spring boot, Resilence4j).

Yoga or new brand: a large-scale project that consisted of merging the IT system of SG with that of Crédit du Nord and other regional banks.

I performed load tests to evaluate the system's capacity to handle additional clients from Crédit du Nord (Gatling).

SPP: I developed a smoothing software component to distribute notifications planned during communication campaigns over time without causing delivery delays across the entire system (Kafka, Spring boot).

Vision 360: These are REST web services that list all alerts sent to clients. And which are intensively used in advisor dashboards.

I migrated these web services from mongodb to oracle exadata.

API-sation: To comply with the Architects' requirements, I declared, versioned, and secured a part of the web services on the Sparky platform, where all SG web services are cataloged.
