Hi, I’m Domagoj Puljic, a backend software engineer with a MSc in Computer Science. I design robust APIs, model data with PostgreSQL, and deploy cloud-native solutions on AWS using Docker, Kubernetes and CI/CD pipelines. I specialize in Python (FastAPI, Django, Flask) and love turning complex requirements into scalable, maintainable systems. I thrive in cross-functional teams, own the full SDLC, and continuously optimize for reliability and speed. I’ve led root-cause analyses to improve stability, reduced incident resolution time by 30% through in-house tooling and automated testing, and enjoy translating domain needs into practical tech solutions for production teams.…Hi, I’m Domagoj Puljic, a backend software engineer with a MSc in Computer Science.
