Lazar Jovanovic

I've built secure, scalable SaaS and healthcare platforms across HubAI.D-Vision, Ibis Instruments, Marble IT, and Victora. At HubAI.D-Vision, I architected a project management platform from the ground up with Nest.js and React.js to help small and medium-sized businesses track tasks, manage resources, and collaborate.

I've delivered microservices, RESTful APIs, automated Docker and GitLab CI deployments, and third-party integrations while prioritizing security, maintainability, and reliable releases. I also refactored monolithic applications into microservices and mentored junior developers on front-end and back-end best practices.

At Ibis Instruments, I developed financial-data charts and interfaces, improved database performance through query optimization and caching, and strengthened platform security with user roles. At Marble IT, I built Node.js and Express.js APIs for patient management, including encrypted data, authentication, authorization, testing, and MySQL optimization.

I bring more than 10 years of experience across JavaScript, TypeScript, React.js, Node.js, NestJS, and DevOps tooling, with a focus on user-focused web applications that perform reliably at scale.
