Mahira Zabin

Undergraduate Teaching Assistant at University of Calgary

Replaced Excel workflows with Power Apps UI and SQL/Dataverse (validation, RBAC, audit trails), saving 40 hours/month and reducing data-entry errors. Migrated 1 million+ records from Excel to Dataverse and relational databases; built incremental ETL pipelines with staged bulk loads, normalized schemas, and integrity checks, enabling ~45% faster queries and daily-refresh dashboards. Replaced 150+ data routines with set-based operations, enhanced CI tests and runtime alerts, achieving ~20% faster pipelines and 99%+ on-time SLAs.

Led end-to-end React/TypeScript well-compliance platform for 9,000+ wells, reducing manual review by 42+ hours per month (~$50K/year productivity). Built telemetry microservices (control logic, pipelines, API/UI) to auto-tune setpoints, boosting energy efficiency and delivering ~$11M value annually. Implemented Cosmos DB data pipelines and Node microservices to automate well checks, enabling accurate well testing and ~$30M production impact. Shipped secure REST APIs and containerized services on Azure for reliable releases and higher uptime. Collaborated with ML team to build Bit Brain, a conversational NVIDIA NIM-based AI engineering assistant, improving operator safety check times from 2 hours to 5 minutes.

Data Engineer Intern at STEP Energy

Led data engineering work across well-compliance platform and telemetry pipelines, delivering end-to-end features with React/TypeScript frontend integration, Azure-based microservices, and Cosmos DB pipelines. Automated well checks via Node microservices and secure REST APIs; containerized services for reliable releases; collaborated with ML team to build Bit Brain AI assistant; contributed Jest tests across microservices and UI, improving quality.

Replaced Excel workflows with Power Apps UI and SQL/Dataverse (validation, RBAC, audit trails), saving 40 hours per month and cutting data-entry errors by 25%. Migrated 1 million+ records from Excel to Dataverse and a relational database using staged bulk loads; added indexes and partitions, enforced integrity checks, and built incremental Extract-Load-Transform pipelines → ~45% faster queries and daily-refresh dashboards. Refactored 150+ data routines (stored procedures and ETL jobs) to set-based operations, used SQL window functions, and tuned execution plans; added CI tests and runtime alerts → ~20% faster pipelines and 99%+ on-time SLAs.

Contributed to data engineering tasks including building and optimizing ETL pipelines, data validation, and data modeling across multiple locations (Calgary, Vancouver).

Developed data pipelines across Vancouver teams; leveraged SQL/Dataverse to improve data quality and delivery timelines.
