Message

At HERE Technologies, I contributed to the design and development of the HERE Reference System framework for stabilising identifiers across multiple data providers.

At Shell Recharge Solution, I led a team of five building and maintaining microservices and AWS Lambdas for the SRS Data Integration Hub. I improved service testability, observability, and availability, and led the platform's decommissioning and transition.

Earlier, I contributed to scalable betting and customer engagement platforms at Grand Parade part of William Hill and SoInteractive S.A. My work has focused on Scala, functional programming, distributed systems, and reliable data-processing services.
