At TalentCross, I developed and maintained Java 8 transaction features for Red Link’s multivendor ATM application. I implemented insurance and banking-product flows that connected ATM screens and transaction states with central systems.
I also developed integrations using XFS middleware and NDC messaging to exchange states, presets, and responses with banking systems. I traced incidents across ATMs, Device Handler, authorization systems, and Base24 on HPE NonStop, then validated deliveries with JUnit, Mockito, simulators, and a lab.
At Assert Solutions, I developed e-commerce integrations and microservices for Newsan using Apache Camel and Red Hat JBoss Fuse. I participated in modernizing connectors from SOAP/XML to REST/JSON APIs with Java 21 and Spring Boot.
I automated reconciliation and CSV file generation for exchanges with Magento, and implemented extended-warranty and insurance integrations for Magento, Motorola, and LG. I also developed a SurveyMonkey NPS connector and resolved production incidents using integration routes, logs, and database data.
