I'm Aleksandr Baumgertner, a Senior Full-Stack Engineer with 10+ years of experience.
I build and modernize digital products — from fast-moving MVPs to enterprise-scale platforms.
I specialize in React, Next.js, Node.js, and MongoDB. I love working in lean teams where speed, clarity, and quality matter.
I’m a developer driven by feedback from end users. I care about the whole delivery process — from writing code (with AI help) to monitoring and collecting feedback. I enjoy building clear processes that allow experimentation while keeping product quality high.
