At my current role in a financial institution, I: • Designed and deployed end-to-end monitoring pipelines, automating 8 critical banking reports (daily & monthly) used by 4 operational areas — significantly reducing manual work and improving delivery times. • Orchestrated scheduled workflows in Apache NiFi processing hundreds of thousands of customer records per batch, generating segmented output files across 4 channels (ATM, Engage, Easy Call, Omnichannel) for banking campaign execution. • Managed and monitored 9+ production pipelines, ensuring availability, integrity, and traceability of sensitive financial data. • Built re-ingestion and urgent reprocessing flows to recover from external failures in batch processes, ensuring operational continuity with direct impact on end users. • Performed root cause analysis and end-to-end incident resolution in production, including query optimization and refactoring in Hive/Impala. • Developed ingestion pipelines from Kafka into refined, consumption, and Datamart layers, covering both batch and near real-time architectures. • Managed data lineage, metadata, and governance using Apache Atlas in compliance with financial industry standards. I'm comfortable handling sensitive data under strict governance frameworks and working on critical systems where reliability is non-negotiable. Additionally, I have a Full Stack development background (Next.js, React, Node.js, PostgreSQL), which lets me bridge the gap between data infrastructure and product when needed. less -
