What I'm looking for

I am looking for a collaborative environment that fosters innovation and growth, where I can leverage my skills to tackle challenging problems and contribute to impactful projects.

With over 9 years of experience as a Full Stack Engineer, I have honed my skills in web development, particularly in Video Production, E-commerce, and Healthcare platforms. My expertise lies in utilizing modern technologies such as React, Node.js, and Python to create scalable and efficient applications. I have a proven track record of managing large-scale projects, optimizing performance, and enhancing user experience through innovative solutions.

At Videopixie, I successfully implemented a Microservices-based architecture and integrated AI-powered functionalities that improved video categorization accuracy by 18%. My leadership in frontend development and the establishment of a design system led to a 32% reduction in development time. I am passionate about mentoring junior developers and fostering a collaborative team environment, ensuring that we continuously grow and innovate together.

My journey has equipped me with a comprehensive understanding of the software development life cycle, Agile methodologies, and a strong focus on performance and scalability. I am eager to leverage my technical expertise and problem-solving skills to drive growth and innovation within a dynamic software development team.
