One project, start to finish: the database, the app that uses it, and a forecast from the data it collects.

What we build

Hire us for one piece or the whole path, from your website and app to the data behind them and what it tells you.

Database design

We model your data so it stays accurate as your business grows: no duplicate records, no conflicting numbers, and queries that stay fast.

  • ER diagrams and data models
  • Normalization and clean-up
  • SQL, stored procedures, and triggers
  • Moving data out of spreadsheets
  • Security, users, and backups
  • Oracle and MySQL databases

Websites and mobile apps

We design your website and a matching mobile app, so customers can find you, learn about you, and reach you from any device.

  • Custom website design
  • Companion mobile apps
  • Designs that work on any screen size
  • Online forms, booking, and ordering
  • Secure hosting and SSL setup
  • Updates and maintenance

Database applications

We build the tools your team and customers use to work with your data, on the web and on their phones, all connected to the same reliable database.

  • Web apps with secure logins
  • Mobile apps for phones and tablets
  • Forms that replace paper and email
  • Dashboards and reports
  • Student and customer portals
  • Connections to the systems you have

Data science

We turn the data you already collect into clear answers, with the statistics to show how much you can rely on each one.

  • Regression and forecasting
  • Prediction and confidence intervals
  • Hypothesis tests and A/B tests
  • Machine learning models
  • Probability and risk analysis
  • Plain-language reports and charts

Questions your data can answer

A few of the questions a good database and the right analysis can settle.

How many units will we sell next quarter?
Forecasting with a range you can plan around.
Which customers are likely to stop buying?
Machine learning models that flag who to contact first.
Did the new process actually make a difference?
Hypothesis tests that separate real change from noise.
Why don't our reports agree with each other?
A single, well-designed database behind every report.
Can our staff enter data from their phones?
A mobile app connected straight to your database.
What drives our results the most?
Regression that shows which factors matter, and by how much.

How we work

Every project follows the same four steps, so you always know what comes next.

  1. Discover

    We learn how your business uses data today and what you need it to do.

  2. Design

    We design the website, app screens, database, and reports before building.

  3. Build

    We develop the site, apps, and database, test them with your data, and train your team.

  4. Analyze

    We put your data to work with statistics and models, and keep improving the system.

Tools we use

  • Oracle
  • MySQL
  • SQL and PL/SQL
  • PHP
  • Python
  • R
  • Excel
  • HTML, CSS, and JavaScript
  • Web and mobile frameworks

The expertise behind every project

Our work is led by university faculty who teach database systems and statistics at the undergraduate and graduate levels. Every project gets the same care as a well-taught course: a clear plan, careful design, and results explained in plain language.

Founded by Dr. Quevedo, university professor of database systems and statistics.

  • Database designData modeling, SQL, and PL/SQL, taught at the university level.
  • StatisticsRegression, prediction intervals, and hypothesis testing, applied to real data.
  • TeachingUndergraduate and graduate courses, so results come with clear explanations.
  • Training your teamDocumentation and hands-on training so your staff can use what we build.
