Full-Stack Developer Needed to Build MVP for Healthcare Scheduling SaaS (Web App)
Nazariy did an excellent job working on my project. He was professional, reliable, and very responsive throughout the project. Communication was clear, deadlines were respected, and the quality of his work met our expectations. I would definitely recommend Nazariy and the CodePhusion for future projects.

My focus 🎯 is on using Java, Spring Boot, React.js, PostgreSQL, and AWS to deliver reliable, scalable software. As a Java developer, I have delivered dozens of projects across industries and use cases.
My backend work is built entirely with Java. I create secure APIs and microservices using Spring Boot. I have deep experience in system architecture, backend performance, and database design. Every project I take as a Java developer is written with clean, maintainable Java code. I know how to structure services that scale.
As a Java backend developer, I have built and maintained systems for high-load traffic, third-party integrations, and complex business logic. I manage full backend pipelines, from architecture and development to deployment and monitoring. I use Spring Boot and follow best practices every Java developer should apply.
I also work as a full stack Java developer, connecting Java backends with React.js and JavaScript frontends. I create dashboards, user interfaces, and admin tools that are fast, stable, and fully integrated. I know how to deliver full stack features without bottlenecks.
I have led teams as a senior Java developer, mentoring other developers, reviewing Java code, and improving team performance. My clients rely on me not just for development, but also for decisions about architecture, data structure, and deployment strategy. As a Java developer, I care about the full picture.
In most projects, I take the role of a Java spring developer and own the backend infrastructure. I work with Docker, PostgreSQL, REST APIs, and cloud services. I often work independently, taking full responsibility for both backend and frontend parts as a full stack developer.
Being a professional Java developer means I deliver production-ready code, meet deadlines, and communicate clearly. I work well with teams or as a solo contributor. My background as a Java backend developer and Java spring developer allows me to adapt to different project needs.
If you need a Java developer who can work on backend systems, full stack features, or cloud-based platforms, I am ready to help. Whether you need a senior Java developer, a Java backend developer, or a reliable full stack Java developer, I can take your project from idea to production.
