Hello, I'm
Daniel Herrera
Data Analyst & Automation Specialist
Analytical thinker. Engineering foundation. Systems-first approach.
01.About
Engineer by training, analyst by practice. My background in mechanical design gave me a systematic way of approaching problems — that same structure now applies to data pipelines, automation flows, and digital operations.
I work with Python, R, SQL, n8n, and GoHighLevel to build systems that measure, automate, and scale. Whether it's a data case study or a full automation flow for a client, I think in processes first.
Looking for roles where technical depth and execution matter — data analysis, process automation, or digital operations.
