About Me

From Processes to Pipelines.

Hi! I’m Derick Velez and I am an aspiring Data Engineer and Python developer with background in Industrial Engineering. I originally started my career in production planning and process engineering, an experience which helped me hone my skills in problem-solving, data analysis, and process optimization

After working on data-driven tasks in these roles, I transitioned into web development, where I developed a strong interest in backend systems and data workflows. I’m now focused on Python development, specializing in building and maintaining data pipelines, automating processes, and working with modern data orchestration tools.

I strive to build systems that are efficient, reliable, and scalable. I enjoy learning new ways to contribute, develop projects, and grow as a contributing member of the tech field.

Work Experience

Planning Engineer

2020-2022

I have experience in production planning and scheduling, monitoring production data such as output and shipment backlog, and coordinating shipment status to ensure smooth operations.

Jr. Process Engineer

2022-2023​

I have experience in monitoring overall production data, including production and process yield, conducting data analysis, and managing product information such as product and die-set history. My work also involved product evaluation through Measurement System Analysis (MSA) and investigating product-related issues.

Worked on projects with responsibilities spanning UI testing, documentation, data migration, and SQL analysis. Contributed to application feature development, data modeling, and testing. Also developed Python-based data pipelines, prepared cloud infrastructure with Terraform, and deployed containerized applications using Docker and AWS (ECR, ECS).
