Open to Analytics Engineer roles · EU / Netherlands ·

Hi, I'm Carlos. Analytics Engineer — data modeling, orchestration & ELT

I build the layer between raw data and decisions: reliable, tested, well-documented data models on top of warehouses like Snowflake and DuckDB, orchestrated with Prefect and served as self-serve analytics. Since January 2025 I've been building analytics infrastructure at RESRG Automotive for 200+ users across 20+ plants.

Where I've worked

Analytics Engineer
RESRG Automotive · Global automotive manufacturer
Jan 2025 — Present

Own the analytics layer of a global operations platform — near-real-time models over 800M+ rows in Snowflake, incremental pipelines, event-driven orchestration, and governed self-serve reporting for 200+ users across 20+ plants.

Near-real-time modeling at scale. Architected near-real-time analytical models for a warehouse/operations system processing 800M+ rows in Snowflake, with event-driven Prefect orchestrations triggered when upstream ERP/operations data lands via CDC replication.
Incremental loading. Implemented strict incremental loading strategies in SQL, cutting stock/inventory data load times by ~95%, and automated supply-policy and role-based inventory logic.
Data integration & governance. Unified operational data with multiple third-party source systems (EHS, HR, quality) into governed Snowflake models; set standards for 130+ KPIs across 20+ plants via a Streamlit/dbt governance app.
Performance & cost. Re-engineered the end-to-end refresh pipeline (Streamlit → Snowflake → Power BI), cutting runtime by ~98%, compute cost by ~90%, and model/measure footprint by ~80%.

Data Scientist — Internship
Biomedical Data Science Lab (BDS Lab) · ITACA — UPV
Nov 2023 — Jul 2024

Research internship — an end-to-end Python framework to evaluate healthcare ML models for fairness, robustness and explainability (XAI).

Model evaluation. Handled missing/noisy clinical data (MICE imputation, PCA/Hotelling's T² outlier checks) and compared models via AUC with cross-validation and bootstrap confidence intervals.
Fairness engineering. Measured performance gaps across sensitive subgroups and tested mitigations (re-weighting, SMOTE), documenting which reduced disparities without sacrificing overall AUC.
Explainability. Produced SHAP-based explanation reports translating model drivers into clinician-friendly insights to support review and trust.

Projects & case studies

End-to-end data products I've built. Each has its own page — the business problem, the technical decisions and why, figures read straight from the project's dbt manifest, an honest status section, and what I'd do differently now.

A bit about me

Carlos De Manuel

I'm an Analytics Engineer based in Valencia, Spain. I found my way into data through biomedical engineering, where the most interesting problem wasn't training the model — it was making messy data trustworthy and usable for the people making decisions.

Today I sit between data engineering and analytics: I model data, write tested transformations, orchestrate pipelines, and ship self-serve products. At RESRG Automotive I've built platforms serving 200+ users across 20+ plants in three regions — and on my own time I build ELT pipelines with dbt, DuckDB and Prefect to keep sharpening the craft.

I care about the boring things that make data reliable: clear definitions, tests as contracts, documented lineage, and pipelines that fail loudly instead of quietly lying. I'm now looking for an Analytics Engineer role in a European scale-up, ideally in the Netherlands.

How I work

Problem first

Start from the decision to be made, not the tool. The stack serves the question.

Tests as contracts

Data quality isn't a phase. Pipelines should fail loudly, never lie quietly.

Build to scale

Modular, documented, version-controlled models. Lineage anyone can follow.

Ship & iterate

The best model is the one people actually use. Deliver, measure, refine.
