What I'm looking for

I am looking for a role that fosters innovation, collaboration, and growth opportunities.

I'm a Senior Software Engineer with over 9 years of experience in developing scalable web applications using Ruby on Rails and React. My journey in technology has been marked by a commitment to delivering high-quality software solutions that enhance user experiences and drive business success. I have a proven track record of leading cross-functional teams to implement complex projects, including a freelance job marketplace that significantly improved user engagement.

Throughout my career, I have specialized in backend API development, database optimization, and cloud-based solutions. At IBM Consulting, I developed a machine learning-powered recommendation engine that improved match accuracy by 25%, and I successfully deployed applications on AWS, optimizing resource usage and reducing costs. My technical expertise extends to various programming languages and frameworks, allowing me to adapt to different project requirements and deliver results that exceed expectations.

I am passionate about leveraging technology to solve real-world problems and continuously seek opportunities for professional growth. I thrive in collaborative environments where innovation and creativity are encouraged, and I am eager to contribute my skills to a forward-thinking organization.
