Using data to solve high-impact problems in healthcare, finance, and business.

My work demonstrates how predictive analytics, machine learning, and business intelligence can help organizations identify risk earlier, forecast future outcomes, allocate resources more effectively, and make stronger financial and operational decisions.

The common thread across every project is simple: turn complex data into an action that creates measurable value.
Sara Seri, business analytics professional
Three professional pillars

One analytical approach applied to different industries.

Data science becomes valuable when it is connected to a decision, a stakeholder, and a measurable outcome.

01

Healthcare Analytics

Patient-risk identification, preventive cost reduction, demand forecasting, and hospital resource optimization.

02

Financial Analytics

Financial modeling, SEC filing text analysis, market-signal evaluation, forecasting, and evidence-based investment interpretation.

03

Machine Learning for Business

Classification, regression, forecasting, ranking, validation, explainability, and optimization across complex organizational problems.

What data can help organizations do

Predict, prioritize, optimize, and communicate.

PredictEstimate future risk, cost, demand, and performance.
PrioritizeFocus limited resources on the highest-value opportunities.
OptimizeRecommend actions under financial and operational constraints.
CommunicateTranslate technical results into executive decisions.
Selected evidence

Real results from healthcare and financial analytics projects.

Cross-industry applications

Machine learning can support almost any organization with data and decisions.

Healthcare

Risk prediction, cost prevention, demand forecasting, patient segmentation, and resource allocation.

Finance

Market signals, risk analysis, forecasting, fraud detection, credit scoring, and investment research.

Operations

Capacity planning, staffing, scheduling, inventory, maintenance, and process optimization.

Business Intelligence

Dashboards, KPI monitoring, trend analysis, executive reporting, and strategic planning.

Marketing

Customer segmentation, churn prediction, campaign measurement, and lifetime-value analysis.

Risk & Compliance

Anomaly detection, scenario analysis, model governance, and evidence-based oversight.

Public Sector

Resource targeting, program evaluation, demand forecasting, and community-level decision support.

Real Estate

Portfolio performance, occupancy, pricing, operating trends, and asset-management insights.

Healthcare and finance together

Two sectors where better predictions can change lives and protect value.

HEALTHCARE IMPACT

Use data to support earlier care and stronger operations.

  • Identify elevated risk before complications
  • Prioritize preventive intervention
  • Forecast capacity and staffing needs
  • Reduce avoidable pressure and spending
FINANCIAL IMPACT

Use data to understand risk, performance, and future opportunity.

  • Evaluate financial and market signals
  • Test whether text adds predictive value
  • Improve forecasting and scenario analysis
  • Support transparent, evidence-based decisions
