Senior Java Developer

Endava
The client, a digital marketing agency, sought to make advertising campaign planning
more user-friendly and give clear forecasts of ad impressions across various platforms.

Improved user satisfaction and campaign performance by 10% by
implementing new features that allowed users to estimate impressions for their
advertising campaigns, streamlining the planning process and enabling clients to
compare actual results with initial estimations.

Skills: Java 11, Spring boot, Hibernate, PostgreSQL, gRPC, ActiveMQ, Kafka, Swagger,
Elasticsearch, Docker containers

Java Backend Developer

Endava
The client, a multinational financial technology company, needed to add strong
customer authentication for the processed transactions to comply with the new EU
regulation and also implement a mechanism for recurring subscription payments.

Guaranteed that transaction processing aligns with the new EU regulations,
enabling merchants in EU countries to maintain access to a user-friendly payment
service with a distinctive interface, rather than being required to navigate various
APIs based on the customer's bank affiliation.

Increased the company's annual revenue by $80 million by implementing the
previously mentioned strong customer authentication and a mechanism enabling
merchants to process recurring subscription payments from their customers using
the payment service.
