Grace Ann Mascarenas

I’m a Programmer Analyst and ETL Developer at Nityo Infotech, working closely with Business Analysts to design solutions, estimate requirements, and turn business needs into reliable data pipelines.

I design, develop, and implement ETL/ELT data pipelines for batch and real-time streaming integration toward a data platform, with a strong focus on performance tuning and optimization.

I’ve designed and maintained Datastage ETL jobs that integrate data from multiple sources into enterprise data warehouses, and I optimized ETL workflows to reduce processing time by 50%. I also automate repetitive data tasks using Shell scripting and SQL procedures.

Previously at Accenture, I delivered end-to-end support for incidents and client requests, translated insights into actionable analytics-based solutions, and programmed data workflow software based on defined requirements—bringing both engineering discipline and analytical thinking to every delivery.
