Whether you require short-stint capacity coverage during a heavy data sprint, scale validation architectures, or technical co-authors to secure a major RFP bid, we deliver rapid operational turnarounds.Location: Dunedin, New Zealand (Available for local or direct global remote contract deployment).

Context: A major global medical device manufacturing corporation required external expertise to audit an internal instrument designed to evaluate employee product training programs.

The Challenge: The internal development team lacked specialized psychometric oversight, resulting in poor alignment between individual test items and the core behavioral constructs they intended to measure.What I Did: Executed a comprehensive methodological audit to refine question design, provided an empirical literature review brief to establish content validity, and developed a strategic blueprint for digital deployment and post-collection data analysis.The Impact: Successfully aligned the instrument with industry evaluation standards, equipping the corporate training division with a scientifically validated framework capable of producing reliable professional development data.

The Challenge: The firm possessed a massive raw dataset of 10,000+ international participants but lacked the specialized statistical infrastructure required to isolate true market penetration trends from systemic noise.What I Did: Designed and executed advanced data-cleaning protocols and rigorous statistical filters to isolate distinct consumer behavior patterns and emerging digital currency adoption trends.The Impact: Delivered a synthesized suite of high-level empirical insights, empowering the startup to deliver authoritative, data-backed strategic recommendations directly to their primary financial technology client.

Context: A fast-growing fintech UX research startup required specialized data engineering and statistical analysis to extract clean, reliable consumer insights from a high-volume global dataset.

Context: A multi-million dollar international development initiative demanded rigorous educational oversight and a longitudinal monitoring framework to evaluate localized engineering capacity across developing nations in Africa and the South Pacific.

The Challenge: The multi-year grant required a standardized system to verify that decentralized instructional materials across diverse global sites were effectively translating into technical self-sufficiency.What I Did: Steered the structural development of the instructional materials, designed pre/post assessments to measure longitudinal learning outcomes, and engineered a comprehensive framework to monitor localized implementation.The Impact: Established a self-sustaining educational infrastructure, successfully qualifying regional leaders who continue to independently operate and maintain low-cost sustainable utility systems 10+ years post-project.

The Challenge: The government required absolute statistical certainty regarding the validity and reliability of national achievement scales and affective surveys before utilizing the data to alter public frameworks.What I Did: Directed the overarching assessment design, executed rigorous scale validations, authored comprehensive national technical reports, and translated complex psychometric models into clear executive portfolios.The Impact: Established the empirical foundation for national-level benchmarking, delivering defensible, high-impact technical insights directly to the ministry executive office to inform immediate educational policy decisions.

Context: A national education agency required top-tier psychometric oversight and structural validation for massive-scale national assessment frameworks to guide immediate, high-stakes policy decisions.

Context: A federally funded science education platform required expert psychometric validation and a comprehensive evaluation architecture to meet stringent federal reporting compliance and state re-certification standards.

The Challenge: To maintain compliance for professional development funding, the digital platform needed to definitively prove its efficacy in shifting educator pedagogical standards and self-efficacy for teaching new science education curriculum.What I Did: Provided expert guidance to the instructional design team on item writing best practices, engineered a formal program evaluation plan, and constructed multi-lens research instruments to track Key Performance Indicators.The Impact: Validated the platform’s educational efficacy through rigorous pre/post metrics and specialized confidence scales, satisfying all federal reporting benchmarks required for practicing teachers to secure re-certification credits.

Effective evaluation isn't something you tack onto the end of a project; it is a continuous cycle that ensures accountability, data integrity, and measurable impact from day one. I build my data instruments to align strictly with the Centers for Disease Control and Prevention (CDC) 6-step framework, creating a rigorous structure that boards, funders, and stakeholders trust.

1. Assess the Context – Understand your program's environment and engage stakeholders collaboratively to define what success looks like.
2. Describe the Program – Clarify goals, resources, activities, and expected logic models before counting data points.
3. Focus the Evaluation – Design targeted research questions so you don't waste time or money collecting irrelevant metrics.
4. Gather Credible Evidence – Deploy balanced, bias-resistant data tools to capture your true performance metrics.
5. Generate and Support Conclusions – Analyze and cross-verify findings against established benchmarks to draw reliable conclusions.
6. Act on Findings – Translate your complex datasets into clear, actionable reporting for your funders and leadership.
