About

AI Engineer & Product Builder.

I build automation systems, AI products, and interactive applications that solve operational and business problems. I enjoy turning complex workflows into systems that are practical, scalable, and useful. My background in sales and marketing shapes how I identify problems, think about users, and design products.

Builder first.
Engineer second.

Before moving into software engineering, I spent over five years in sales and marketing. I worked in customer acquisition, led outreach campaigns, trained teams, and spent a lot of time understanding how businesses grow and why customers make decisions. That experience gave me a practical understanding of operations, execution, and the importance of systems.

Over time, I kept running into the same problems. Teams were spending hours on repetitive work, outreach didn't scale, and important processes depended too heavily on manual effort. I became interested in automation because I had experienced these problems firsthand.

Why I Build Systems

I spent five years working in sales and marketing before moving into engineering. That experience taught me how businesses operate and exposed me to repetitive problems that could be solved with better systems. Most of the products in this portfolio began as attempts to solve problems I encountered firsthand or repeatedly observed. Building systems became my way of turning those frustrations into practical solutions.

Principles

How I work.

Ship Fast
I prefer building and validating ideas quickly. A working system in production tells you more than a perfect design in a document.
Think in Systems
I design workflows, not isolated features. Every component I build is part of something larger. I design it that way from the start.
Build for Reliability
I care about failures, monitoring, and long-term maintainability. A system that runs unattended needs to fail loudly or not at all.

Let's build something.
Open to projects, collaborations, and the right opportunities.
