About Me

The term DevOps holds immense value to me as it reflects my expertise in both development and operations. After starting my journey as a Full Stack Developer in 2014, I integrated DevOps into my work routine in 2018. Since then, I have effectively deployed resources on AWS using Terraform, created CI/CD pipelines, and managed Kubernetes in production environments. By leveraging my development skills, I have successfully assisted countless developers in enhancing their operations experience and delivering superior software outcomes. Currently, I’m working on a project that promotes healthy and sustainable design practices, aiming to improve people’s lives in the society at Fitwel. Here are a few technologies I've been working with recently:

AWS
Terraform
Observability
CI/CD
Programming Languages (Typescript, Javascript, Go, Java, Kotlin)
Frameworks / Libraries (Node.js, Express.js, React, Angular, NEXT, NestJS, Spring Boot)
Testing (Cypress, Selenium, Jest, Mocha, Chai, JUnit)
SQL and NoSQL databases (Oracle, MySQL, Postgres, MongoDB, CouchDB)
Agile Methodologies (SCRUM, Kanban)
