About Vladimir Elisavetsky

I’m an AWS Certified Full Stack Developer with 6 years of experience delivering scalable solutions using.NET Core, Node.js, React, Angular, and React Native. I hold a Bachelor's degree in Computer Science and Mathematics and bring a strong foundation in both front-end and back-end development. I thrive in both team environments and independent roles. I’m passionate about clean architecture, performance optimization, and building developer-friendly ecosystems. I've contributed to internal tooling, introduced scalable file structures, guided monorepo adoption with Lerna, and helped implement team-wide coding standards. I value mentorship, continuous learning, and delivering production-ready solutions that are maintainable, testable, and secure. I'm known for my problem-solving mindset, adaptability, and clear communication.
