About Alexander
I'm a Senior Full-Stack Engineer and Tech Lead with 7 years of experience across backend, AI, frontend, and cloud. My main stack is TypeScript, Node.js, React, and AWS, and I focus on end-to-end delivery from zero to production - most recently deploying an AI pipeline that cut document processing costs by 95%. I take on part-time freelance roles to help fast-moving products launch faster, establish technical standards, and solve their hardest engineering bottlenecks.
