Core development contributor to CAPI Gateway, a cloud-based solution for sending advertising events via server-to-server communication. This product, targeted at thousands of advertisers, is designed to handle millions of events per second, providing a scalable and efficient way to process large volumes of advertising data.

Features:

• High-Performance Architecture: Built using Vert.x, enabling low-latency, high-throughput event processing.

As part of the core development team, I was responsible for:

• Developing critical backend functionalities using Kotlin and Vert.x to optimize event processing.
• Collaborating on system architecture to ensure reliability and scalability for millions of events per second.
• Took ownership of the observability workstream for the first year of product development.
