Hire the Best Statistical Modeling Professionals

I help building owners, developers, and design teams close the gap between how a building is modeled and how it actually performs — combining building energy modeling with mechanical (MEP) design to reduce energy use, operating costs, and carbon impact. Most freelancers do either the energy model or the mechanical design. I do both, which means the two actually align — and you don't need to coordinate between two separate hires. Why clients work with me: • Integrated energy modeling + MEP design under one roof • Code-fluent across ASHRAE 90.1, NECB, Title 24, IECC, BREEAM, and Passive House • Data-driven, fully documented, on-time deliverables 🖥 Energy Modeling & Sustainability EnergyPlus, DesignBuilder, IESVE, PVsyst · ASHRAE 90.1 / Title 24 / NECB / IECC compliance · energy audits (ASHRAE 211, ENERGY STAR) · 179D support · daylight, thermal comfort & PV feasibility studies 🏢 Mechanical (MEP) Design HVAC system design (VRF, AHU, chillers, boilers, heat pumps) · heating & cooling load calculations · plumbing, fire protection & gas systems · full Revit MEP modeling with clash detection · equipment selection, BOQ & specs 🏊 Specialized: Pool & High-Humidity Spaces Hydraulic design, equipment sizing, and HVAC for pool halls and spas 📊 Engineering Analysis & Automation FEM & CFD simulation · MATLAB modeling · Python automation for engineering workflows 📩 Let's bring your high-performance building vision to life — message me to discuss your project.

I'm a Top Rated freelancer and Computer Science graduate who works at the intersection of three fields most people treat separately: Statistics & Machine Learning, Bioinformatics, and AI. That combination is exactly what messy, high-dimensional data needs — the statistical rigor to trust the result, the ML to find the pattern, and the biological context to know what it means. With 3+ years of experience and 24 successful projects (4.98/5 avg. rating), here's what I bring: 📊 Statistics & Machine Learning Rigorous statistical inference and predictive modeling — hypothesis testing, causal inference (Mendelian Randomization), feature engineering, and ensemble models (XGBoost, LightGBM, Random Forest). I don't just build models that score well; I build models you can defend. Example: a coronary artery disease prediction model reaching 0.956 AUC, with feature ablation to prove what actually drives it. 🧬 Bioinformatics & Omics End-to-end analysis of complex biological data — scRNA-seq, RNA-seq, WGS/WES — using reproducible pipelines (Nextflow, Snakemake). From raw reads to normalized matrices to differential expression and biomarker discovery. Example: cut analysis time by 40% on large genomic projects through custom automated pipelines. 🤖 AI & Deep Learning Deep learning frameworks for real diagnostic problems — computer vision, medical image analysis, NLP, and LLM-based tools. ✨ What ties it together Most freelancers do one of these. I connect them — applying AI and ML to biological and clinical data with statistical discipline, then communicating the findings in publication-ready visuals that both scientists and stakeholders can act on. 🛠️ Tech Stack Python (Pandas, Scikit-learn, TensorFlow, PyTorch) · R (Tidyverse, Bioconductor) · Bash · SQL · Linux · Git · Docker · Cloud 💡 Ready to turn your raw data into discoveries you can trust? Let's talk.
