@davidfernandoesparza
Senior Engineer specializing in Data Engineering, ETL pipelines, and scalable full-stack architecture.
What I'm looking for
I’m a Senior Engineer with over 7 years of experience in full-stack architecture, system modernization, and data automation. I architect scalable solutions using Python, SQL, and AWS, with a technical focus on Data Engineering, ETL pipelines, and Machine Learning. I thrive on optimizing distributed systems, automating data-heavy workflows, and driving technical leadership in agile environments.
Most recently, I built an automation system with Python and Pandas to extract and transform academic datasets into standardized protocol documents. In past roles, I led portal modernization with React and Astro, managed high-availability Python/Django systems using Kubernetes on AWS, integrated Apache Kafka for reliable event-driven streams, and restructured Elasticsearch/MeiliSearch clusters to reduce query latency.
