What I'm looking for

I’m seeking a Lead Data Architect role where I can apply my business intelligence and dashboard strengths to manage global analytics deployments, drive data governance, and deliver executive-ready decision support through scalable frameworks.

I’m a Senior Data Analyst with over seven years of expertise turning complex, multisource datasets into strategic business intelligence for C-level leaders. I’ve directly partnered with CEOs and COOs to build single-source-of-truth dashboards, define and track KPIs, and deliver conclusive ad-hoc insights that support real decisions.

At Optimetriks, I spearheaded analytics across 30+ countries and 15+ Fortune 500 clients (including Nestlé and Vodacom), cutting manual processing by 85% through Python-driven ETL automation and SQL optimization. I design scalable analytical frameworks—instrumenting alerts for proactive actions, improving data quality and reliability, and collaborating across engineering and stakeholders to strengthen global analytics deployments and governance.
