Healthcare research systems · UTHSCSA / VA Research Center
VA Hospital Research Data Warehouse
Built and supported healthcare research data warehouses integrating VA hospital data, national datasets, and multi-domain clinical sources.
Contribution
- Worked across MUMPS-derived hospital data, flat files, relational databases, pharmacy, laboratory, inpatient, and outpatient sources.
- Designed SQL Server and SSIS transformations that turned operational healthcare data into research-ready structures.
- Implemented cleaning, outlier detection, validation, reconciliation, and provenance-aware data preparation.

Nephrology and chronic-disease research
NIH-Funded FIND Study Registry
Designed registry structures for nephrology and chronic-disease research, balancing protocol-driven data collection with real-world clinical variability.
Contribution
- Structured research data around diabetes, ESRD, nephropathy, and related chronic-disease questions.
- Balanced formal study definitions with missingness, coding variation, and inconsistent operational source data.
- Supported research teams where cohort logic and clinical meaning mattered as much as the statistical model.

HIE and Clinical Trial Data Platforms
Architected proprietary HIE and CTMS platforms that translated clinical workflows, patient data, trial protocols, and operational requirements into structured systems.
Contribution
- Designed database and application structures across interoperability, clinical-trial, and digital workflow requirements.
- Created mobile-enabled clinical data collection tools aligned with CDISC practices and Phase II/III trial workflows.
- Led architecture, data modelling, validation logic, reporting, user workflows, and data-quality controls.

Hospital operations research
Functional Job Analysis System
Developed a system for hospital operations research by modelling human work, task overlap, and workflow structure as analysable data.
Contribution
- Translated descriptions of hospital work into explicit, structured information.
- Modelled tasks, overlap, and workflow relationships so operational patterns could be examined systematically.
- Workflow modelling
- Requirements analysis
- Structured data

Research synthesis systems
Meta-Analysis Platform
Created a platform for synthesising heterogeneous research outputs where data alignment, definition consistency, and comparability were core challenges.
Contribution
- Structured unlike research outputs so their definitions and results could be compared.
- Made alignment decisions and comparability constraints explicit instead of hiding them inside reports.
- Research data
- Semantic alignment
- Data modelling

Mojo · Machine learning education · Literate programming
mojoLLM Computational Notebooks
A growing collection of Python-style, browser-readable notebooks that use Mojo to build machine-learning ideas from first principles.
Contribution
- Added a reproducible Jupyter-to-HTML publishing pipeline with isolated, responsive notebook embeds for any Markdown essay.
- Established a first-class mojoLLM category so notebook essays remain browsable as a distinct body of project work.
- Created the opening notebook: a perceptron implemented from scratch, with each prediction and weight update exposed step by step.
