Experience
Analytics Self-service Transformation
In the second phase, I collaborated with business leaders to align on a single source of truth for key KPIs. I designed and optimized underlying data models to resolve ambiguity and establish foundational trust in the data.
I then architected custom, intuitive Looker Explores tailored to stakeholder needs. I automated the most time-consuming manual reports into dynamic dashboards, creating a unified, governed platform for cross-team collaboration.
In the next stage, I developed a tailored curriculum and led hands-on training sessions, empowering end users to navigate standardized models and confidently self-serve their own data queries.
As a result, we achieved a 75% reduction in ad-hoc reporting requests. We successfully shifted a siloed data culture to a collaborative one, freeing up analytics bandwidth for high-impact, strategic initiatives.
Trimodal Revenue Forecasting Engine
I then standardized real-time opportunity data from internal sales platforms, engineering custom velocity metrics to capture conversion rates, sales cycle lengths, and stage-to-stage deal momentum. I also executed Monte Carlo simulations to model potential revenue outcomes based on historical volatility and synthesized probabilistic simulations with pipeline data streams into a single predictive engine.
I back-tested the three-point model against historical actuals to refine the algorithm, applying rigorous statistical thresholds to ensure model stability and reliability under varying market conditions. Finally, I deployed the model to executives, establishing a new organizational standard for predictability. I delivered revenue projections with 80% accuracy at a 90% confidence interval to drive strategic planning.
