About Me

I'm a dedicated Full-Stack Developer with a passion for building robust, scalable software solutions. With experience across various technologies, I enjoy tackling complex challenges and creating efficient systems that deliver real value.

My journey spans both backend and frontend development, where I've designed APIs, implemented microservices architectures, and crafted intuitive user interfaces. I'm continuously improving my English proficiency while actively developing two main projects: LLT, a language learning platform that combines my technical skills with my interest in languages, and ToolsZone, a suite of web-based utility tools designed with simplicity and performance in mind.

I'm particularly focused on creating tools that solve real-world problems, emphasizing clean code, performance optimization, and excellent user experience. My current tech stack centers around TypeScript, NestJS, React, and NextJS, with a growing interest in AI integrations and developer productivity tools.
