Portrait of Mauricio Alessandrello

Automation

Increased productivity by automating data analysis.

Visualization

Supported decision-making with clean, insightful visualizations.

Reporting

Concise, interactive reports that are both informative and appealing.

Machine Learning

Built an ML tool to reduce the error rate of analytical results.

Portfolio

Selected projects

Real-world analytics tools for laboratories and data exploration. Every project includes a write-up of its logic and workflow.

Shiny data visualization app
  • R
  • Shiny
  • Shinylive

A Shiny Application for Data Visualization

Visualizes environmental and food safety lab results across 24 sample types with interactive scatter plots, histograms and a full analyte correlation table. Filter by client, adjust axes and add reference lines. Runs entirely in your browser via Shinylive (may take a moment to load). All data shown are synthetic.

React and D3 data visualization app
  • React
  • D3.js
  • JavaScript

Interactive Data Visualization App — React & D3.js

A full JavaScript reimplementation of the Shiny app, built on the same synthetic data. Scatter plots, histograms, correlation table, custom axis scaling, client filtering and reference lines — a native browser experience with no R runtime required.

Groundwater monitoring map with well status
  • JavaScript
  • D3.js
  • Leaflet
  • R

Groundwater Monitoring — Map, Charts & Reports

Tracks the water chemistry of production and monitoring wells on a satellite map. Each well has interactive time-series charts and a traffic-light status against regulatory guideline levels, and a monitoring report can be printed to PDF or exported to CSV in one click. R prepares the data; the app runs entirely in your browser, with no server. All data shown are synthetic.

Laboratory KPI dashboard
  • R
  • Shiny
  • KPIs

A Dashboard of KPIs

A KPI dashboard for laboratory management. Line charts, bar charts, treemaps and value boxes give a high-level view of operational health with minimal effort. "World Laboratories" is a fictional brand and all data shown are synthetic.

Automatic incubator data analysis app
  • R
  • Shiny
  • Time series

An Application for Automatic Data Analysis

Analyzes microbial culture incubator data. Upload raw data to generate interactive time-series charts; value boxes and tables quickly reveal non-compliances and temperature deviations. The app opens with synthetic example data.

Airbnb Buenos Aires search app
  • R
  • Shiny
  • echarts4r

Airbnb Apartment Search — Buenos Aires

Fast search and analysis of Airbnb listings. A high-performance echarts4r map, sliders and dropdowns for precise filtering, and tooltips with key apartment details on hover.
