About Me

With over 8 years of experience in web and mobile technologies, I specialize in creating efficient and scalable applications that drive business growth and enhance user experiences.

My expertise spans the entire development stack, from front-end frameworks like React and Next.js to back-end technologies such as Node.js and NestJS. I'm passionate about leveraging cutting-edge tools and methodologies to deliver robust, high-performance solutions.

Beyond development, I have extensive experience in DevOps practices, creating and managing cloud infrastructure. I've worked with containerization technologies like Docker and Kubernetes, and implemented robust CI/CD pipelines to streamline deployment processes. This DevOps expertise allows me to not only build applications but also ensure they're deployed and scaled efficiently in production environments.
