Ognjen V.

I’m a Software Engineer building scalable web applications across healthcare, business, and marketing domains. I started my career in frontend development, building modern, user-centered interfaces using React and Next.js, with a strong focus on clean UI architecture and performance optimization. Over time, I expanded into full-stack development, working with Node.js and PostgreSQL to design reliable backend services and database models for production environments. Most recently, I’ve focused on complex architectures within the healthcare sector, building integrated multi-application systems that require secure, real-time communication. This involved designing structured API contracts for bidirectional data exchange and integrating Jitsi for reliable video-based services within distributed environments. I’m highly proficient in Linux (Ubuntu) and Docker-based workflows, and comfortable handling environment configurations and service-based deployments. I enjoy translating complex business requirements into clean, maintainable technical solutions that scale reliably in production.
