My Work: How I Can Help
Data systems & governance
I design and create data infrastructure that businesses can trust and scale; from models, pipelines and governance frameworks. I work in complex environments where data has never been properly structured and the foundation needs building from scratch.
I turn messy, unstructured, inconsistent data into clear trustworthy insight. Dashboards, reports, and analytics that leadership or management can actually use to make decisions. I use tools like dbt, Snowflake, BigQuery, Tableau, Looker Studio, GitHub, Power BI, SQL.

About Tess Ogamba
I'm a quantitative data and analytics leader who walks into companies where data is an absolute mess and builds the entire engine from scratch or refines existing architecture.
With a BSc in Biostatistics and over eight years of experience, I step into environments with zero infrastructure or precedent, take over the chaos, and design data systems that senior leadership can actually trust.
I don't sit in a silo. I can write raw SQL queries to untangle a broken database schema, run complex analysis, and present the growth strategy to leadership in the same week. My work bridges data engineering, product strategy, and data culture.
I identify hidden flaws in data pipelines, challenge performance frameworks built on unverified assumptions, and upskill non-technical teams into high-performing analytics professionals. I engineer the structural foundations that move commercial metrics and shift company direction.
