About

I’m a software engineer with experience in C#, Java, and Python, currently pursuing a joint MSc in Computer Science at the University of Amsterdam and Vrije Universiteit Amsterdam. I enjoy designing scalable systems, building robust APIs, and creating intuitive user interfaces that bridge people and technology. Before my master’s, I worked at Siemens Technology and Services as a .NET developer, where I contributed to multiuser collaboration features for the TIA Portal, improving real-time project synchronisation and system performance. My current research focuses on semantic modelling and Linked Data, where I’ve developed a knowledge graph from smart apartment IoT data using SAREF 4.1 and QLever. This project deepened my understanding of RDF, SPARQL, and data interoperability, and strengthened my interest in data-driven sustainability. Beyond academics, I serve as Head of Communication for the Faculty of Science Student Council, working to improve student engagement and collaboration across the university. I’m passionate about software architecture, data engineering, data integration, and sustainable digital systems and I'm always open to conversations about system design, Linked Data, or making technology work smarter for people and the planet. 📧 sreepadmavathybalaji@gmail.com
