About

The engineer behind the results

Production mechanical engineering first. Then data, method and code.

My journey started in Production Mechanical Engineering: designing systems, solving physics problems, and understanding how things actually work. From there, I pursued a Six Sigma post-graduate specialization, an MBA in Business Management, and certificate programs at HarvardX (edX) in Data Science: Probability and Entrepreneurship in Emerging Economies.

But education was never the end goal; application was. Since 2012, I have applied these frameworks hands-on, trained 500+ professionals, published two books on the methodology, and built WeCazza, a software platform used by home service teams. Across client projects, capacity gains have averaged 35% or more. Each case is different.

“Engineers don't publish theories they haven't tested. Theory doesn't count until real operations testify.”JJ Andrade
