What I'm looking for

Seeking a challenging role in a dynamic organization that values innovation, teamwork, and growth opportunities, with a focus on scalable systems and cybersecurity.

I'm Ujjawal Yadav, a driven and detail-oriented software developer with a strong foundation in computer science and a specialization in data science. With a keen interest in scalable systems and cybersecurity, I excel in collaborative environments and thrive in fast-paced settings.

Throughout my academic and professional journey, I've developed a diverse skill set, leveraging technologies like Java, Python, Node.js, and MongoDB to drive innovative solutions. My experience in Agile development methodologies and proficiency in languages like English and Hindi enable me to effectively communicate and work with cross-functional teams.

I'm passionate about creating efficient and user-centric applications, as evident in my projects, such as Github-Roast and Tempest-Teller. I'm excited to bring my skills and enthusiasm to a dynamic organization, driving growth and success in the tech industry.
