I'm a seasoned Software Engineer with a Bachelor’s degree in Computer Science and over 7 years of experience specializing in Ruby on Rails and React.js. Throughout my career, I've been deeply involved in crafting various features, designs, and modules that have contributed to the success of multiple projects.

My expertise extends to building sophisticated front-end systems using a range of cutting-edge technologies, including JavaScript, jQuery, Sass, TypeScript, SCSS, and Bootstrap. With a solid grasp of software engineering principles, I've honed my skills in the essential create, read, update, delete (CRUD) methodology, ensuring efficient and effective data management.

One of my strengths lies in test-driven development (TDD) using tools like RSpec, as well as behavior-driven development (BDD) with Cucumber and Capybara. I've also taken the lead in designing RESTful API endpoints, effectively bridging the gap between front-end and back-end systems.

I take immense pride in my work, consistently delivering clean, efficient, and reliable code while adhering to project timelines. My experience extends to utilizing AWS for cloud-based solutions, and I thrive in collaborative team environments that follow Agile methodologies.

As a highly focused and self-motivated professional, I thrive on challenges and take a proactive approach to problem-solving. Throughout my journey, I've built a reputation as a dedicated team player, successfully managing diverse responsibilities and contributing to the development of robust applications.
