Senior .Net Developer

Role & responsibilities

ur platforms exchange data with airlines, customs, ground handlers, forwarders and banks through many point-to-point interfaces built over the years. Some are slow, hard to monitor and fail silently, and users feel it as delays, rework and manual follow-ups. In this role you will move those interfaces to an event-driven integration layer on Apache Camel and Kafka, find and fix the bottlenecks that slow users down, and add practical AI features to existing applications. You will work directly with users and customers, so the measure of success is faster, simpler processes for them, not just new technology.
