Apps & Software
I build specialized software tools that translate complex psychological and linguistic science into accessible, user-centric applications.
Empirical Predictive Engines
Zero-Latency Decoupled Statistical Dashboards.
Clinical-grade analytics engineered for B2B and SaaS platforms. Built natively with absolute data privacy (edge computing) using robust longitudinal mixed-effects models—guaranteeing deterministic, audit-ready point estimations and standard errors with zero “AI hallucinations.”
PQM: Practice Quality Mindfulness Tracker
Precision measurement for meditation practice.
Based on the Practice Quality-Mindfulness scale (Del Re et al., 2013), PQM helps practitioners track the quality—not just duration—of their sessions to optimize mental health outcomes.
Compute_ES: Compute Effect Sizes
Professional Effect Size Calculator.
A privacy-first web app for calculating and visualizing meta-analysis effect sizes (\(d\), \(g\), \(r\), \(OR\)). Features batch CSV processing and interactive distributions.
Stanford C-Score (Ranking Tool)
Are you in the Top 1% of Scientists?
A live calculator that scrapes Google Scholar to compute your Composite Score (C-Score) based on the Ioannidis/Stanford methodology. Check your global ranking status instantly.
Veloz: Language Learning via Language Islands
A scientifically-grounded language acquisition tool.
Veloz uses the “Shadow Loop” method—an audio-lingual technique focused on rapid repetition and phonological loop activation—to help users internalize new languages naturally.
Interactive Slang Explorer
Master real, authentic street Spanish.
A highly visual, interactive guide to the slang, idioms, and street-level expressions they don’t teach you in a textbook. Dive into regional humor, cultural context, and conversational nuances. Test your fluency and begin mastering the authentic Spanish you’ll actually hear on the streets.
R Packages (CRAN)
I have developed and maintain several open-source R packages that serve as foundational tools for the meta-analysis and statistical community.
compute.es
The Gold Standard for Effect Size Calculation
When precision matters, compute.es is the engine researchers trust. It effortlessly converts between dozens of effect size metrics (\(d\), \(g\), \(r\), \(z\), \(OR\)), ensuring your meta-analysis is built on bedrock data.
- Impact: Cited in 372 studies on Google Scholar.
- Reach: 263,537 total downloads.
MAd
Taming Heterogeneity (Mean Differences)
Meta-analyses are messy. MAd brings order to the chaos of dependent effect sizes. It provides robust aggregation methods that allow you to squeeze every ounce of power from multi-outcome studies without violating statistical assumptions.
- Impact: Cited in 182 studies.
- Reach: 106,919 total downloads.
MAc
Correlational Precision
Correlations are not just numbers; they are relationships. MAc specializes in the meta-analysis of correlation coefficients, handling the complex dependencies that standard packages ignore.
- Impact: Cited in 74 studies.
- Reach: 51,799 total downloads.
