What I'm looking for

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

I am a Full Stack Software Engineer with over 5 years of experience in designing, developing, and maintaining scalable web applications. My expertise lies in React, TypeScript, Java, PostgreSQL, and Docker. I have a proven track record of leading feature development and deploying cloud infrastructure on platforms like Azure and AWS. I thrive in Agile environments and excel in asynchronous, fully distributed teams.

Throughout my career, I have engineered scalable Java microservices and built high-performance frontend applications that enhance user experience. My commitment to writing clean, maintainable code is reflected in my ability to refactor legacy applications into TypeScript, improving overall code quality. I have also developed automated testing suites, achieving over 90% code coverage, and implemented CI/CD pipelines to streamline releases.

In addition to my technical skills, I have a passion for mentorship, having guided university students in programming and software development principles. I am eager to contribute my skills and experience to a dynamic team that values innovation and collaboration.
