Dereck Mendez — Building intelligent systems from data to decisions.
I build data and machine learning solutions that turn real-world problems into measurable, reproducible outcomes — from analysis and experimentation to reliable systems.
Analytics
End-to-end projects solving real problems.
A selection of projects where I combine data analysis, statistical reasoning, machine learning and engineering to move from a business question to a working solution.
A forecasting system designed to predict operational demand and service-related metrics, combining historical patterns, calendar effects and machine learning to support planning and resource allocation.
Tools I use to analyse data, build models and turn experiments into reproducible systems.
Hi, I'm Dereck.
My path into data has been shaped by a combination of business experience, analytics and software development. I enjoy understanding the problem behind the data before thinking about the model.
Today, I'm focused on growing as a Data Scientist and Machine Learning Engineer, with a particular interest in the engineering practices that make ML systems reproducible, maintainable and useful beyond experimentation.

From business experience to data and ML.
Full experience →Currently working at the intersection of analytics, software and data-driven solutions, while continuing to develop my expertise in Machine Learning and MLOps. My current role lets me understand real business problems and connect them with technical solutions, while further expanding my experience in data workflows, analytics and engineering.
Consolidated my transition toward a more analytical view of the business, combining people management with People Analytics, automation and Business Intelligence. I built report automations with Python and dashboards in Power BI and Looker Studio to turn data into insights and KPIs that supported process improvement and decision-making. Working with data and business needs across Guatemala, Costa Rica and El Salvador broadened my regional perspective and strengthened my ability to connect people data with real business goals.
What I can actually do.
Let's build something meaningful together.
I'm open to opportunities where I can contribute across Data Science, Machine Learning, analytics and the engineering behind reliable data products.
Whether you're looking for someone to analyse a problem, build a model or help turn an experiment into a more reliable system, I'd be happy to connect.
