Erez Lev.

Software Engineer

I'm a software engineer who thrives at the intersection of technology and impact. With 5 years of experience across startups and enterprise, I don't just write code, I understand the why behind it. Whether it's shipping AI-powered features, optimizing systems for scale, or launching side projects from scratch, I bring ownership and curiosity to everything I build.

Projects.

Independent ventures and freelance work that showcase my ability to ship products end-to-end.
