Description

Over the past 8 years, I have been working as a full-stack web developer, focusing primarily on building CMS systems with rich UX/UI interfaces. My main strength lies in backend development with Node.js (around 70% of my daily work), while the remaining 30% involves frontend frameworks such as Vue.js, Angular, and React.

Throughout my career, I have gained extensive experience in designing and maintaining RESTful APIs, implementing CRUD operations with ORM tools (Sequelize, Knex, Mongoose), and integrating SQL/NoSQL databases such as PostgreSQL, MSSQL, MongoDB, and Redis. I have also been involved in streaming technologies (WebRTC, RTSP, RTMP) and serverless cloud architecture, primarily on AWS (Lambda, API Gateway, S3, Load Balancers, CodeBuild), along with experience on Azure, Google Cloud, and DigitalOcean.

In addition to my development expertise, I have over a decade of experience in adjacent IT fields including ERP systems and network administration. My DevOps skill set includes Docker, CI/CD pipelines, Jenkins, and infrastructure as code with Terraform.
