About Me
As a full stack Engineer, I have a comprehensive understanding of both front-end and back-end development. I have experience with React, Angular, jQuery, Node.js (Express/NestJS), Django, and SQL/NoSQL databases. I build and deploy web applications, design and implement databases, and create/consume RESTful APIs. I work with Git/Bitbucket, Nginx, PM2, Docker, Redis, RabbitMQ, and server setups (MySQL/Mongo). I enjoy shipping reliable products and collaborating with cross-functional teams.
