Led the data-platform team supporting analytics, data science, and marketplace business units for a major MENA mobility platform. Architected an in-house ETL framework orchestrating hundreds of production pipelines daily. Framework-level optimizations produced approximately $60K in annual infrastructure savings on one pipeline and reduced operational overhead across the platform. Acted as consulting architect for data science, analytics, and backend engineering leaders, shaping cross-functional architecture decisions and long-term technical direction. Established integration standards between the central data platform and marketplace product teams. Founded an internal Data Academy to scale data-engineering practices across product, analytics, and engineering teams.
Senior Software Engineer / Big Data at Agoda 2015 - 2016

Engineered multi-region replication of an ALS recommendation model across five data centers, providing consistency, fault tolerance, and low-latency serving. Designed a reactive DAG framework using Akka actors and futures to compose asynchronous data and inference flows. Partnered with data-science teams on ETL pipelines for offline ML training and high-quality feature data.
