Turning data into defensible decisions
OQuant is an independent data science consultancy founded in March 2025 by Rodrigo Hermont Ozon — economist, econometrician, and PhD researcher in Systems and Industrial Engineering. The premise is simple: business decisions deserve the same rigor as peer-reviewed research. OQuant combines econometric modeling, statistical validation, and modern AI engineering to deliver analyses you can defend in front of a board, an auditor, or a regulator — not black boxes, and not slideware.
What OQuant does
Forecasting & Time Series
Demand, price, and volatility forecasting with classical econometrics (ARIMA, GARCH-family, GAMLSS, Bayesian MSGARCH) and machine learning hybrids — with honest out-of-sample validation, not curve-fitting.
Econometric Modeling & Causal Inference
Answering "what actually drives this?" — regression diagnostics, panel and instrumental-variable methods, quasi-experimental designs, and Bayesian multicausal models grounded in economic theory.
Risk Analytics & Simulation
Quantitative risk measurement and scenario analysis: Monte Carlo simulation, extreme value modeling, portfolio and multi-objective optimization for pricing, sourcing, and investment decisions.
Machine Learning & Predictive Modeling
Supervised and deep learning models (including CNN+LSTM architectures and survival analysis for predictive maintenance) built with proper feature engineering, ablation testing, and MLOps discipline.
Business Intelligence & Decision Support
KPI frameworks, dashboards, and analytical pipelines that turn scattered data into a single, trusted view — from data modeling and governance documentation to executive-ready reporting.
Generative AI for Business
Practical LLM applications: internal chatbots, multi-agent and sub-agent workflow orchestration, and AI-assisted knowledge management — designed around your processes, with measurable value.

A disciplined engagement model
Diagnostic
We start with the business question and the decision it must inform. I audit the available data, map the constraints, and define success criteria before a single model is fit. If the data cannot support the question, you hear that on week one — not at delivery.
Modeling & validation
Candidate models are built, stress-tested, and compared against honest baselines with out-of-sample and backtesting protocols. Assumptions are documented, uncertainty is quantified, and every result comes with its limitations stated plainly.
Deployment & handoff
Deliverables are reproducible: versioned code, documented pipelines, and dashboards or APIs your team can own. I train your people so the solution outlives the engagement.
Monitoring & advisory
Optional ongoing support: performance monitoring, model recalibration, and advisory sessions as new questions emerge — so the analytics keep pace with the business.
What you are actually buying
PhD-level rigor
Active doctoral research in multi-objective optimization, Bayesian econometrics, and time series at PUCPR, an MSc in Economic Development (UFPR), peer-reviewed publications, and reviewer roles for journals such as Applied Soft Computing. The methods behind your project are the ones surviving academic scrutiny.
15+ years of industry track record
Hands-on delivery inside large organizations — Volvo Group, BRF, CNH Industrial, Unimed — plus UNDP/UN research work and years of economic analysis for industry federations. I know how corporate data, politics, and deadlines actually behave.
End-to-end capability
From statistical theory to production code: econometric specification, Python/R/SQL implementation, cloud data pipelines (Azure, Databricks, PySpark), and MLOps. One consultant covers the full path from hypothesis to deployed system.
Let’s talk about your problem
A first conversation costs nothing and usually clarifies whether quantitative modeling can move your decision — and whether I am the right person to build it.
