A Little Bit About Myself

My work has accelerated time-to-market by 30% and reduced manual effort by 80%, showcasing a commitment to delivering high-impact, innovative solutions.

Front-end development
I convert design prototypes into responsive, scalable, and high-performance web applications. I use frontend frameworks, design systems, and testing tools to deliver ahead of schedule.
Back-end development
I engineer products with modular, robust, and dependable services. I work across various languages in managed and serverless environments, backed by comprehensive unit and integration tests.
Development Operations
I maintain a rapid, steady, and organized development cycle with a blend of operational knowledge. I leverage Docker for development, ensure continuous integration and delivery via CircleCI, and orchestrate infrastructure using Terraform.
