Designed, developed, and maintained end-to-end ETL pipelines to ingest data from multiple sources, apply business rules, and load curated datasets for BI reporting and analytics. Built complex Talend jobs using core components such as tMap, tJoin, tDBInput/tDBOutput, tFileInputDelimited, tFileOutputDelimited, tRunJob, and context variables for reusable, parameter-driven workflows. Implemented robust data cleansing and validation (null/duplicate checks, referential integrity, standardization, reconciliation) to ensure trusted, audit-ready outputs. Developed Python utilities for automation, logging, exception handling, and pre/post-load data quality checks, improving pipeline reliability and reducing manual effort. Created scalable transformations in Azure Databricks using PySpark (DataFrames) and Spark SQL to process large datasets and deliver analytics-ready tables. Implemented Delta Lake patterns to support incremental loads and consistent refresh cycles. Optimized Spark workloads by applying partition pruning, broadcast joins, caching/persisting, shuffle tuning, and handling data skew to improve runtime performance and cost efficiency. Scheduled, monitored, and supported production runs using Talend Administration Center (TAC) and enterprise schedulers (e.g., Autosys), including retries, alerts, and SLA adherence. Built and maintained Power BI semantic models and dashboards using Power Query and DAX measures, delivering KPI-focused insights for business stakeholders. Improved report responsiveness by optimizing data models (star schema), relationships, DAX, and refresh strategies (including incremental refresh where applicable). Authored and tuned SQL/PL/SQL for efficient extraction, transformations, and reconciliation, ensuring performance data movement and accurate reporting outputs. Collaborated with stakeholders to gather requirements, prepare source-to-target mappings, define transformation logic, and deliver solutions aligned with business goals and reporting needs. Performed root-cause analysis for ETL/data issues by analyzing logs, rerun strategies, and data discrepancies; implemented permanent fixes and preventive controls. Produced clear documentation for ETL jobs, mappings, and lineage; ensured maintainability, knowledge transfer, and compliance readiness.
