Staff Data Engineer @ Zego

London, UK

Own the Data Engineering platform end-to-end — Iceberg lakehouse infrastructure and Snowflake/dbt analytics — leading the introduction of Apache Flink and Protobuf-based PII/GDPR governance across the platform.

Fully scoped and led the introduction of Apache Flink to Zego's data platform, driving the migration of streaming ingestion from a legacy Kinesis/Scala/Protobuf pipeline to a Flink-based forwarder.
Leading GDPR/PII governance by extending the company's Protobuf schema contract with field-level PII annotations, driving automatic PII derivation and masking across the data lake and Snowflake's B2B/B2C domains.
Own Iceberg lakehouse infrastructure (Terraform + AWS S3/IAM, Polaris catalog) and its Snowflake integration across staging and production environments.
Evaluated OLake (Debezium-based database-to-Iceberg replication) and a Kubernetes CRD for Polaris catalog management as ingestion PoCs, contributing upstream fixes to the open-source olake-helm Helm chart.

Staff Data Engineer @ Just Eat Takeaway.com

London, UK

Lead the Streaming Ingestion team, building self-service tooling that enables product teams to stream and manage real-time data across a multi-cloud estate. Drive the "left-shift" initiative: a declarative DSL on top of Apache Flink that lets domain teams design, deploy, and own their own data products.

Architected a self-service streaming platform abstracting Flink, Kafka, and multi-cloud connectivity behind a unified DSL — cut onboarding time for new data products from weeks to days.
Lead schema management and data connectivity strategy across GCP and AWS, standardising contracts between producers and consumers.
Selected as speaker at Flink Forward 2025 to share the team's approach to productionising self-service streaming.
