Hi, I’m Dejan Keserović, a Senior Full-Stack Software Developer with 5+ years of experience building scalable, high-performing web applications. I’ve worked on a wide range of projects, from high-scale enterprise systems to personal side projects, helping businesses improve their software and streamline processes. I handle both frontend and backend development and take pride in managing projects from start to finish, ensuring smooth and efficient execution. I also have a strong background in database design, with research experience that’s given me a deep understanding of how to structure and optimize databases for large and complex systems. I’ve published several scientific papers on the topic and was also a speaker at the International Conference on Information Systems Development (ISD) 2025. My key skills and technologies include: • Java, Java/JEE, Spring Boot, Spring Framework (MVC, Security, Data) • Maven, Gradle • .NET, C# • React, TypeScript, HTML, CSS • SQL databases: MySQL, MSSQL, Oracle, PostgreSQL • REST API development and integration • Writing clean, efficient, and well-tested code • Project design, testing, deployment, and maintenance • Strong communication and collaboration I’m looking forward to working together!
