Profile

From business needs.
To working software.

Full stack engineering,
product delivery, and leadership.

My work spans frontend and backend applications, APIs, data integrations, and AI features. I connect these parts into complete solutions, whether I’m building a new product, modernizing an existing system, or improving how a business operates.

I take responsibility from the first discussion through implementation, launch, and ongoing development. Working with founders, product managers, and designers, I define requirements, weigh tradeoffs, and build solutions that balance usability, performance, and maintainability.

I also lead engineering teams, mentor developers, and establish practical processes for planning, code review, and delivery. Combining hands-on engineering with leadership helps me keep the product, codebase, and team aligned as business needs evolve.
