Gabriela Jachs Stepien Atwell
Senior Business Analyst
I bring clarity to complexity — transforming messy processes and confusing data into clean systems and insights that every team can understand, trust, and act on.
ABOUT
From Porto Alegre, RS, Brazil → San Diego, CA — a focused journey in tech & operations
I'm a Senior Business Analyst with 10+ years of experience improving operational performance through requirements gathering, process mapping, and translating business needs into clear delivery outputs. My background started in Biomedical Informatics (UFCSPA), where I learned how to work with complex datasets, validate quality, and turn analysis into real outcomes.
After moving to San Diego, California, I shifted into business analysis and operations—where I found my strongest impact: building structure, reducing cycle time, and strengthening decision-making through dashboards, automation, and standardized workflows.
In roles across operations, finance, sales, and technical teams, I've supported delivery end-to-end: discovery, documentation, cross-functional alignment, UAT / regression testing, rollout, and adoption. I care about outcomes that are measurable and repeatable—less rework, fewer defects, cleaner data, and faster execution.
Most recently, as Senior Business Analyst at Time Wise Luxury, I've led requirements elicitation, business process reengineering, and workflow automation initiatives that accelerated pipeline growth, eliminated billing discrepancies, and delivered measurable cost savings across the organization.
I'm currently continuing my education in Business Administration & Information Technology while building scalable systems that help teams operate with clarity, speed, and confidence.
What I do
- Gather and document requirements, map processes, and translate needs into delivery-ready outputs.
- Build dashboards and KPI reporting to surface bottlenecks, trends, and operational performance.
- Design validation and reconciliation workflows that reduce defects, rework, and data errors.
How I work
- Discovery → clarity: align stakeholders, document scope, and define success metrics.
- Measure outcomes: track adoption, cycle time, defect reduction, and accuracy improvements.
- Ship safely: iterate in phases with UAT, regression testing, and rollout support.
