Information Systems Engineer

Automation, cloud, and enough AI to make repetitive work disappear.

About

Engineering practical software for real business problems.

I'm an Information Systems Engineer passionate about building solutions that make work simpler. My favorite projects start with someone saying, “We've been doing this manually for years,” and end with a system that quietly takes care of the problem.

At Emerson, I create automation solutions using Power Platform, RPA, and Microsoft Copilot to eliminate repetitive work and improve operational efficiency. I have a strong ability to understand business processes, uncover underlying needs, and transform rough ideas into practical solutions that deliver real impact. I enjoy bridging the gap between technical possibilities and business objectives to build tools people genuinely find useful.

Outside of my professional work, I've developed full-stack applications using Python, FastAPI, React, Next.js, Kotlin, and AWS. My approach is simple: technology should not only work today, but remain reliable, maintainable, and valuable a year from now.

Lately, I've been focused on AI agents and system architecture, exploring how intelligent automation can improve workflows, support better decisions, and create systems that continuously evolve alongside business needs.
