Summary
I have experience across the entire software development lifecycle, including unit, functional, and integration testing. I’ve developed, maintained, and debugged Ruby- based applications and designed and implemented both RESTful and GraphQL APIs. My background also includes a variety of DevOps-related tasks such as working with Docker, setting up bare-metal servers, managing AWS infrastructure, and configuring CI. I follow established best practices and coding conventions (including security standards), yet I remain flexible and adaptable. I’m comfortable working with legacy codebases that lack tests as well as with modern stacks that have full test coverage. I actively share knowledge with my teammates and enjoy mentoring less experienced developers. I’m committed to continuously improving both my technical and soft skills.
