Data Analyst · 2X Tableau Ambassador

Turning raw data into dashboards people actually use.

I'm Tobiloba Babajide - a data analyst with 3+ years spanning analytics engineering and applied economic research. I build the full path from raw source data to governed reporting: dbt models in Amazon Redshift, validated metric definitions, and Tableau dashboards that teams use without an analyst in the loop.

About

From raw source data to governed reporting.

I build analytics that 6 teams across marketing, revenue, and call-center operations rely on daily - from campaign-to-close funnel tracking to performance reporting on human- and AI-handled calls. Recent work cut dashboard load times from over 2 minutes to 15 seconds and removed roughly 400 hours of manual preparation a year from a weekly reporting cycle.

Before that, I produced 100+ recurring price and inflation analyses at Oaks Intelligence, including correlation work against Nigeria's Consumer Price Index - translating economic data into plain-language insight for non-technical readers.

Outside work I'm a 2X Tableau Ambassador and Community Leader, a Lagos Tableau User Group volunteer, and an educator who has trained 100+ students to entry-level job readiness.

Own the analytics layer end to end for 10 production dashboards - from dbt models in the Amazon Redshift data warehouse through to published Tableau Server output - used monthly by 10+ stakeholders across 6 business teams.
Build full-funnel reporting for Ads & Marketing and Revenue Operations: dbt marts that unify campaign, lead-source, and pipeline status-change data so conversion is tracked consistently from first campaign touch through closed revenue.
Model call-level data for Call Center Operations and Voice AI into one schema covering human- and AI-handled calls, joined to quality-review outcomes - powering real-time dashboards of call volumes, outcomes, and agent performance.
Define conversion, pipeline, and pricing metrics with the teams that use them, translating ambiguous requests into scoped written specifications before any build begins.
Rebuilt the ELT processes behind 8 of the 10 dashboards; load times on the heaviest views dropped from over 2 minutes to 15 seconds - an 8× improvement.
Consolidated 10 source systems, including Redshift and MySQL, into 1 governed environment of Git-versioned staging and mart dbt models, replacing conflicting per-team extracts.

Lagos, Nigeria

Automated the weekly price analysis ETL workflow, cutting 8 hours of manual preparation per week - roughly 400 analyst hours annually.
Produced 100+ recurring economic analyses across 21 months on 3 cadences using SQL Server, Python, Excel, and Tableau - covering household affordability, inflation, and commodity price movement.
Ran correlation analysis of retail and wholesale price data against Nigeria's Consumer Price Index, isolating which of 20+ commodity categories led or lagged the national index.
Owned 3 recurring analytical products end to end - the Nigerian Economic League dashboard, the Price Tracker report, and the published newsletter - through written interpretation for non-technical readers.
Investigated anomalies in pricing data collected by 105 geographically distributed field teams, treating unexpected values as errors to trace rather than results to publish.

Two deep dives - one from production analytics work, one from the Tableau Public community.

Analytics Engineering · LexHive

Rebuilding a reporting stack that couldn't keep up

Problem: 10 production dashboards fed by per-team extracts from 10 different source systems. Teams saw conflicting versions of the same metrics, transformation logic lived inside Tableau workbooks, and the heaviest views took over 2 minutes to load.
Approach: Moved transformation logic out of workbooks and into Git-versioned dbt staging and mart models in Amazon Redshift. Standardised statuses and timestamps across campaign, lead-source, and pipeline data, and wrote scoped metric specifications with each consuming team before rebuilding.

Result: load times dropped from 2+ minutes to 15 seconds (8×), and 6 teams now share one governed version of every metric.

Data Visualisation · Makeover Monday

UFO sightings, redesigned as flight paths

Problem: 60,000+ NUFORC sighting records across the contiguous US - a dataset usually shown as a plain dot map that hides shape categories and patterns in the noise.
Approach: Engineered custom sigmoid-interpolated flight paths in Tableau, densifying the data so each sighting shape category traces its own curved trajectory across the map - turning a static scatter into a narrative graphic, built entirely with native Tableau calculations.

Result: an advanced-technique viz demonstrating data densification, table calculations, and custom map design.
