BIOGRAPHY
I'm Sampath Weerasekara, a Software Engineer and MSc Data Science graduate from the University of East Anglia. My journey into technology started with a passion for solving problems and has grown into building software solutions that combine engineering, data, and artificial intelligence.
I have commercial experience developing enterprise applications, REST APIs, and database-driven systems, along with hands-on experience in machine learning, data analytics, and full-stack web development. Throughout my academic and professional journey, I have worked with technologies such as Python, Java, JavaScript, SQL, React, AWS, and Docker to design and deliver practical solutions.
Beyond coding, I enjoy continuously learning new technologies, building personal projects, and exploring innovative ways technology can create meaningful impact. I like oppurtunities where I can contribute, grow, and continue building solutions that matter.
