Professional Summary
Middle Full Stack Developer with 2.5 years of commercial experience engineering scalable end-to-end web
applications, e-commerce platforms, custom administration systems, and Telegram Mini Apps. Proficient
across the entire software development lifecycle with core expertise in React, TypeScript, Node.js, Express,
Bun, and PostgreSQL (Supabase), alongside experience with Java (Spring Boot REST APIs).

Demonstrated backend capability in architecting modular RESTful APIs (Controller-Service-Route pattern),
designing normalized relational database schemas, implementing ACID-compliant transactional SQL
migration pipelines, building custom authentication/authorization middlewares, and integrating cloud storage
(S3/Supabase signed URLs) and asynchronous mailing pipelines. Strong frontend foundation in Feature-
Sliced Design (FSD), Micro-frontends, state management (Zustand, Redux Toolkit), and component-driven UI
with Storybook. Proven track record of technical leadership, mentoring Junior developers, leading code
reviews, and applying AI-assisted workflows to accelerate delivery.
