Available to hire
I’m David Kovacs, a full-stack developer passionate about turning complex problems into scalable software solutions. I specialize in TypeScript, Python, Node.js, React, and Django, and I’ve built platforms—from high-volume data systems to eCommerce backends—that empower teams and customers. I thrive on delivering robust architectures and value-driven software outcomes in collaborative environments.
I enjoy automating repetitive tasks, improving system reliability, and continuously learning new technologies. When I’m not coding, I like refining workflows, mentoring teammates, and exploring creative approaches to product design and user experience.
