Senior Frontend Engineer | React | TypeScript | Node.js | Frontend Architecture & Infrastructure

In October 2019, I took my first steps into the world of programming — self-taught, driven by curiosity, and motivated by a strong desire to build things that solve real problems. What started as a personal challenge quickly became a career I care deeply about.

At the time I began learning to code, I had already graduated with a Bachelor's degree in Law from Tbilisi State University and was pursuing my Master’s degree in Private Law. Despite coming from a non-technical background, I found myself increasingly drawn to problem-solving, systems thinking, and the logical structure of software development.

Just a few months after writing my first lines of code, I joined MiMa IT Services, where I built production-ready interfaces with React and Next.js for client projects and high-traffic web platforms. During my time there, I progressed from intern to junior developer and then to frontend developer, gaining hands-on experience in responsive UI development, backend integrations, and delivering reliable features in production environments.

In May 2022, I joined EIS Ltd as a Frontend Engineer, where I worked on a React-based UI builder, reusable form systems, and a shared design system. That role helped me deepen my experience in component architecture, reusable frontend platforms, and engineering efficiency through tooling and automation.

In August 2023, I joined Bank of Georgia as a Senior Frontend Engineer. There, I build and scale customer-facing and internal web applications in a regulated environment, contribute to frontend architecture, and lead initiatives such as micro-frontend adoption, legacy modernization from Polymer.js to React and TypeScript, SSR solutions, and performance improvements across large-scale web systems.

Over time, I’ve grown from learning the fundamentals of frontend development to designing scalable frontend systems and contributing to architectural decisions across teams. Along the way, I’ve also expanded into backend technologies such as Node.js, Express, GraphQL, and MongoDB, as well as cloud and delivery tooling including AWS, Docker, and CI/CD workflows.

Today, I specialize in building scalable, maintainable frontend applications with a strong focus on architecture, modernization, performance, and developer experience.
