What I'm looking for

I’m looking to lead data engineering and analytics that turn evidence into measurable impact—building reliable pipelines, dashboards, and clear reporting for non-technical stakeholders in mission-driven teams.

I’m a Senior Data Analyst and Data Engineer with 3+ years of experience transforming complex datasets into actionable insights across EdTech, analytics consulting, and financial services. I’m currently the custodian of Click Learning’s learner database, supporting 230,000+ learners across 307 schools in 5 provinces.

My core focus is impact measurement and evidence communication: I design analytical frameworks to measure learner outcomes, build and maintain dashboards in Sisense, and produce reports, briefing notes, and presentations for funders, government partners, and school leadership. I’m hands-on with data quality assurance—identifying gaps, duplicates, timing mismatches, and anomalies—and I collaborate with technical teams to resolve upstream issues.

Alongside analytics, I engineer reliable pipelines and database architecture to collect, transform, and maintain learner, school, and assessment data at scale. I also bring a strong quantitative foundation from Electrical Engineering and experience delivering machine-learning-driven solutions, including model development for fraud detection and recommender-system work.
