Hello! My name is Leo. I am a Backend Developer specializing in Groovy and JVM-based technologies.
I develop reliable, scalable, and high-performance server-side solutions for web applications, APIs, and backend systems.
My work focuses on:
backend architecture
server logic
API development
database integration
automation and performance optimization
I build secure and maintainable systems suitable for modern business needs, including web platforms, SaaS products, and enterprise solutions.
If you’re looking for a backend developer who understands both code quality and system architecture — feel free to contact me.

I have several years of experience in backend development using Groovy and Java-based ecosystems.
I work with server-side technologies, REST APIs, databases, and microservice architectures.
My expertise includes:
building backend services and APIs
working with frameworks based on Groovy/JVM
database design and optimization
security and authentication systems
scalable backend architecture
performance tuning and system reliability
I clearly understand how to design backend systems that are stable, secure, and ready for production environments, and I choose optimal architectures depending on project requirements.

Self-educated in IT and remote workstation solutions. Strong practical experience and continuous learning.
