Professional Experience & Key Deliverables

Lead R Shiny Developer | Environmental Protection Systems

Automated Warning Systems: Developed and modified R Shiny applications to generate real-time, colour-coded environmental warnings (Yellow/Orange) aligned with federal weather standards.

Quarto Integration: Engineered dynamic Quarto (.qmd) templates to produce automated markdown reports, integrating complex logic to trigger specific content based on regional parameters.

CSS & UI/UX Design: Implemented custom CSS and B.C. Design System tokens to ensure web interfaces meet accessibility and branding requirements.

Code Standardization: Refactored legacy R code by creating modular helper functions, standardizing naming conventions, and replacing unmaintained packages (e.g., transitioning from leaflet.esri to modern alternatives).

Mandatory Action Logic: Programmed complex conditional logic to display location-specific "local emissions" bylaws and mandatory action tables within automated web outputs.

Senior R Developer | Climate Data Systems (FFEC)

Spatial Data Mapping: Built interactive map interfaces using R Shiny to visualize climate variables and Biogeoclimatic Ecosystem Classification units.

Package Development: Contributed to the development of R packages (like climr) by optimizing visualization functions and ensuring well-documented code via GitHub.

Performance Optimization: Reduced run times for high-volume data visualization functions by identifying and removing redundant data loads and streamlining CSV/Raster processing.

Project Methodology & Approach

Phase 1: Visual Identity & Logic: Expert at modifying Shiny inputs to assign regional colour codes and updating Quarto websites to reflect these changes using Figma mock-ups.

Phase 2: Regulatory Parameters: Experienced in building "Bylaw Parameter" sets that vary by location, ensuring mandatory actions are programmatically accurate.

Phase 3: Code Health: Dedicated to "Clean Code" initiatives—removing unused data loads, implementing unit tests for edge cases, and standardizing global variables for long-term maintainability.

Education & Certifications

Msc/PhD: (Computer Science, Datascience), Focus on Computational Data Science or Environmental Systems.

Advanced R Programming Certification: Specialist in Shiny and Package Development.
