Description

Senior Data Engineer with 10+ years of experience building and evolving large-scale data platforms across marketplaces, banking, and marketing technology.

I specialise in data platform modernisation, decentralised data architectures (Data Mesh), and production-grade data pipelines, working end-to-end from ingestion and governance to reliability and compliance.

Recently at Adevinta (MarTech), I worked on Project Delorean, helping de-globalise legacy eBay analytics into Business Unit–owned data products, collaborating across Subito, Benelux, and Kleinanzeigen. My focus combined Databricks & Airflow platforms, cross-cloud ingestion, and privacy-critical workflows.

Previously, I contributed to real-time streaming platforms at Santander UK (Kafka, low-latency systems), and spent several years at OLX / letgo, where I helped design and migrate cloud-native data platforms, search & discovery pipelines, and GDPR-compliant data lakes.

Core strengths

- Data Platforms & Data Mesh architectures

- Databricks, Spark, Airflow, Kafka (batch & streaming)

- Cloud data engineering (AWS, cross-cloud ingestion)

I enjoy working at the intersection of data engineering, platform design, and governance, especially in environments where scale, reliability, and autonomy really matter.

Worked on Project Delorean, supporting the de-globalisation of legacy eBay/Shanghai analytical pipelines into Business Unit–owned data products, aligned with Adevinta’s decentralised data strategy.

Contributed across three Business Units, with a primary focus on Subito (Automobile.it) (~70%), and additional work for Benelux (BNL) and Kleinanzeigen (KA) (~30%).

Highlights:
- Led the migration of global ETLs into domain-owned, production-grade data products under a Data Mesh model.
- Rebuilt core Subito pipelines on Databricks, AWS S3/Athena, Airflow, Argo, Delta/Parquet, with strong governance, lineage, and SLA guarantees.
- Supported BNL with GCP → Databricks Unity Catalog ingestion patterns (BigQuery, GA4, PySpark, Airflow backfills).
- Contributed to privacy compliance initiatives in KA, building vendor-facing integrations for Data Deletion Requests (DDR) using Kotlin microservices and DynamoDB.
- Improved internal CDC/SCD engines, Airflow frameworks, and anonymisation tooling used across teams.

Contributed significantly to the GravityPlus Migration Project (Cloudera Exit), transitioning from Cloudera to Confluent to deliver real-time streaming services with sub-200ms latency for retail and corporate clients. The migration involved implementing a high-availability system across two data centers operating in parallel, with dual-region replication in the PaaS environment to ensure fault tolerance and reliability.

- Kafka Connect Jobs: Designed and implemented Kafka Connect jobs for data ingestion, preparation, and synchronization with Oracle, addressing challenges with complex data transformations.

- Enrichment Applications: Migrated 14 stateful streaming applications from Java 8 to Java 17 and Scala 2.13, ensuring seamless functionality and compliance with updated quality and security standards. Also migrated one legacy Apache Flume application to Kafka Streams streaming app.

- Historical Data Migration: Migrated 7 years of historical data from Cloudera Kafka topics and HBase, ensuring zero data loss and uninterrupted service during the transition.

- Documentation & Performance Analysis: Created comprehensive documentation, optimized system performance in production, and defined thresholds with alerting mechanisms for Kafka topic lag to enhance monitoring and operational efficiency.
