David Ariza is a results-driven Ssr ML Engineer based in Bogotá with 9 years of experience building backend systems, ETL pipelines, and production-ready ML infrastructure using Python and cloud-native services. Currently at Mercado Libre, he combines machine learning engineering with hands-on backend microservices work, having previously implemented AWS Lambda-based microservices, Dagster orchestrations, and ETA prediction integrations at Rappi. A Holberton-trained full-stack and ML practitioner, he pairs data modeling and scraping expertise with API-first design—evidenced by his contributions to RESTful endpoints and Swagger docs in open-source projects. Comfortable across the stack, he also brings a marketing-automation and analytics background that helps translate product needs into measurable technical solutions. Notably, he blends practical security-minded touches (e.g., password encryption) into APIs, showing attention to both functionality and operational robustness.
