Lenz AI ENG. & Architect

MY APPROACH

I'm an AI Engineer with a different approach: I know the fundamentals of software development, and I've built a workflow where AI is my copilot. I design the solution and define the architecture; AI helps me write and ship the code faster.

The result: I ship complex projects — learning platforms for doctors, ERPs, chatbots and AI agents — with the speed and precision of someone with years more experience.

My philosophy

“The best engineer isn't the one who writes the most code, but the one who designs better systems.”

Soft skills
Systems thinking
Problem solving
Fast learner
Technical communication
Results-driven
Adaptability
AI-Augmented Engineering

Opencode, Claude, custom skills and agents are a core part of my workflow — not a replacement for engineering skill, but a multiplier of it.
