/ about

I work where analytics, business thinking, and interface design overlap.

My best work usually looks like this:

  • take a noisy dataset or business problem
  • model it into something decision-ready
  • ship it inside a dashboard or UI that feels polished and easy to trust

So whether the job is SQL + Power BI, Python analysis, or a React/Tailwind dashboard, the goal stays the same: make complexity feel simple.


/ current focus

Data analyst side

  • SQL analysis and KPI reporting
  • Power BI dashboards and DAX thinking
  • Python workflows for EDA, cleaning, and forecasting
  • Turning business questions into usable metrics

Frontend side

  • React interfaces for data-heavy products
  • Tailwind layouts with clean visual hierarchy
  • Dashboard UI systems and reusable components
  • Presenting metrics in a way people actually understand

/ toolkit

Skill icons

Core stack        → SQL, Python, Power BI, Excel, Tableau
Frontend layer    → React, JavaScript, HTML, CSS, Tailwind CSS
Sweet spot        → Dashboards, BI products, analytics apps, decision-support UI

/ featured work

SQL + Power BI + Power Query

A healthcare operations project focused on waitlists, specialty demand, and bottleneck visibility.

Why it matters

  • translates raw operational data into clearer planning signals
  • highlights service pressure and wait-time patterns
  • built in a format decision-makers can actually use

Python + machine learning + retention analysis

A churn project built around identifying risk signals and retention opportunities from customer behavior.

Why it matters

  • combines predictive thinking with business context
  • moves beyond reporting into action-oriented insight
  • strong fit for analytics + product decision workflows

Exploratory analytics + pricing insight

An analysis project focused on what actually drives property value and market behavior.

Why it matters

  • useful for comparing pricing factors across listings
  • shows structured exploratory analysis and reasoning
  • turns market noise into interpretable drivers

Frontend presentation + personal brand UI

A visual portfolio space to present work, strengths, and project direction with a cleaner frontend lens.

Why it matters

  • shows product presentation, not just technical output
  • reinforces frontend taste alongside analytics work
  • creates a stronger bridge between code and communication
