Create Java GC dump
Yurii is excellent. He quickly identified and resolved a complex issue with Java and AWS that our team had been unable to fix for over a week. His technical expertise, problem-solving skills, and ability to dive deep into the root cause were truly impressive.
Communication was clear and efficient throughout the process, and he kept us updated at every step. He not only fixed the issue but also ensured everything was stable and working smoothly afterward.
Highly professional, reliable, and a pleasure to work with. I would definitely recommend Yurii and look forward to working together again.

Looking for an experienced Java developer for my project
Yurii was an amazing addition to our team throughout this project. He is talented and incredibly responsible. Yurii was deeply collaborative in every aspect of the design, development, and testing. I was most impressed with how Yurii adapted to using AI as an accelerator during this project. I saw a marked acceleration in our overall project output, and in the age of AI, Yurii's has been a great multiplier for us.

I'm a Senior Java Developer with more than 10 years of commercial experience building stable, scalable, and secure backend systems. I specialize in Spring Boot microservices and cloud-native architecture — and I've shipped production systems in Fintech, EdTech, Healthcare, Retail, Hospitality, etc.
My core strength is backend architecture: clean APIs, event-driven systems, and services that scale. I also work across the full stack development when needed — React on the frontend, Node.js for integrations, and AWS for deployment and infrastructure.
What I bring to your project:
- Production-grade Spring Boot microservices and REST APIs
- Cloud infrastructure on AWS with Docker and CI/CD pipelines
- Full-stack capability: Java backend + React frontend
- Relational and NoSQL databases: PostgreSQL, MySQL, MongoDB
- Clean, maintainable code with TDD and Agile workflows
I've worked on SaaS platforms, enterprise systems, and MVPs — from initial architecture through to deployment.
Go-To Stack:
Java (Spring Boot, Spring Cloud, Hibernate) · React · Node.js · AWS · Docker · PostgreSQL · MongoDB · Jenkins · GitFlow
