Scientific Rigor Meets Technical Execution
I am a PhD Scientist and Senior Manager of Research and Development.
This project gives you:
• Forensic Data Intelligence: My approach combines advanced machine learning (TensorFlow, PyTorch) with rigorous statistical frameworks (Bayesian, Classical, and Psychometrics) to ensure your insights are not just directionally correct, but scientifically sound.
• Explainable ML Solutions: I specialize in building functional, "glass-box" models. My experience includes 5 years of building supervised ML models for pediatric rehab and 5 years in high-stakes qualitative analytics—I ensure you can explain the why behind every insight.
• Flexible Tech Stack: I deliver analyses using the tools that best fit your infrastructure, including Python (Polars, Pandas, SciPy), R, SQL, and interactive visualization platforms like Streamlit, Plotly, and Looker, GCP, AWS.
• Stakeholder-Ready Reporting: You receive a comprehensive Technical Insights Report tailored to your audience from CEOs to technical experts.

AI Coding Tool Workflow and Testimony
Alexander was fantastic to work with. He delivered thorough, well-documented workflow insights and clear testimony for our AI coding tool evaluation — exactly what we needed. We were so happy with the result that we've already hired him for a second contract. Highly recommend.

Python Developer for AI Tool Testing Session (45 Min–1 Hr, $50-200)
Alex was excellent to work with. He brought exactly the kind of senior engineering judgment we were hoping for: clear technical feedback, practical product instincts, and a strong sense for where AI coding tools can help or fail in real workflows. He did not just follow the test instructions, he thought through the product like someone who has actually shipped and reviewed serious software. Communication was clear, the feedback was thoughtful, and his perspective was genuinely useful for improving the tool. I would be very happy to work with him again.

Google Reviews Analytics Insights and Dashboard
We've been sitting on over 1,000 Google reviews for years and never really did anything with them — they were just there. Alex changed that fast. Within days, he pulled out the key themes and recurring topics buried across all that feedback and showed us exactly which issues were most urgent to address. Some of it was eye-opening. We've already started making changes based on his findings, and it's made a real difference in how we think about what our customers are telling us.
On top of the analysis, he built us an interactive dashboard that pulls in our review data in real time, and it even has a chat feature where I can ask questions over the data and get answers instantly. For someone who's never worked with tools like that before, it was surprisingly easy to use. Alex delivered genuine business value from something we'd been completely ignoring.

Job Success
Guelph, Canada - 4:15 am local time
As a PhD Scientist and Senior Research Manager, I specialize in building the transparent frameworks required for high-stakes, automated decision-making. Whether you are navigating complex datasets or developing an Explainable AI (XAI) strategy, I provide the academic rigour and technical oversight needed to transform messy data into clear, defensible, and trusted AI systems.
Impact & Proof
- Enterprise AI Workflows: Oversaw the development of a comprehensive AI Ethical Framework and R&D adoption path, driving the successful launch of 10+ operational and client-facing AI workflows.
- Clinical ML Deployment: Built ML models for pediatric rehabilitation that integrated into clinical therapy programs across home and clinic settings. These applications have been deployed in 2 hospitals, serving 50+ patients and utilized by 10+ clinicians.
- Data Science & Advanced Analytics: Delivered 60+ comprehensive Quality Assurance reports, specializing in extracting actionable insights from messy data and solving fuzzy, ill-defined business questions through rigorous scientific validation.
- Academic Rigour: Authored over 60 peer-reviewed academic journal articles, conference papers, and presentations, grounding my freelance work in cutting-edge, verifiable AI and data science methodologies.
Core Services
Explainable AI (XAI) Strategy
- The Problem: "Our AI makes decisions, but I can't explain why to my stakeholders or my users."
- The Solution: I turn "black box" models into transparent systems with human-readable outputs, ensuring best-practice and stakeholder buy-in.
Scientific Validation
- The Problem: "We know our product has potential, but we lack the rigorous scientific proof to show how great it is."
- The Solution: I design comprehensive, peer-reviewed validation frameworks across the entire scientific workflow—from hypothesis generation, experimental design, and data collection, to statistical modelling, evaluation, and reporting—to definitively prove your tool works safely and accurately in the real world.
Algorithmic Auditing
- The Problem: "We are ready to scale our AI to the next level, but need a defensible governance framework to prove to stakeholders that our models are fair and systematically sound."
- The Solution: Implementing an end-to-end AI governance framework that spans technology evaluation, systems architecture, and ethical policy design, ensuring fair results across user populations and mitigating long-term risk.
(Note: Due to an active non-compete agreement, I am unable to accept engagements related to Higher Education Selection Assessment and Analytics.)

Steps for completing your project
After purchasing the project, send requirements so Alexander can start the project.
Delivery time starts when Alexander receives requirements from you.
Alexander works on your project following the steps below.
Revisions may occur after the delivery date.
Data Intake & Integrity Audit
I perform an audit of your data to understand its structure and ability to answer your question. This includes obscure values, outliers, or sampling biases that could undermine the results.
Exploratory Data Analysis (EDA)
I apply the appropriate models (Predictive ML, Bayesian stats, or Psychometrics) to extract high-confidence insights and answer your question.
