As a skilled web developer with 7 years of experience, I have a strong background in creating and implementing effective and engaging web solutions. I have deep understanding of JavaScript, React and other relevant technologies to help with designing and building high-quality, scalable, and performant UIs that provide a seamless experience for users. I am also familiar with agile development methodologies, which allow me to work efficiently and collaboratively in a team environment. I am also experience in back-end technologies with a keen interest in devops.
Full-stack engineer working on an AI-powered Kubernetes cost optimization platform that automates cluster scaling, resource sizing, and intelligent workload management. I build core backend services in Rust that deliver real-time performance analysis and automated optimization recommendations. On the frontend, I develop web interfaces using Next.js for cluster management and cost visibility. The platform helps engineering teams reduce cloud infrastructure costs while maintaining performance—delivering capabilities comparable to enterprise solutions like CAST.AI with a focus on intelligent automation. Tech stack: Rust, Next.js, TypeScript, Kubernetes, AWS, Docker, MongoDB, DuckDB
