// Michal Kurtulík — independent software engineer

Michal Kurtulík
Software Engineer & Solution Architect

I design and build backend and cloud systems — from software architecture down to real production. I work independently under the Yonix.sk brand and provide services to companies and projects of various sizes on a contract basis.

Services

What I offer under Yonix.sk

04

Independent delivery

I deliver as an external contractor with my own work organization, my own tools and full responsibility for the delivered outcomes.

Projects

Selected projects I have worked on

Cloud Migration & Service Decomposition

Transformation of a monolithic application into microservices on AWS. On-premises to cloud migration. Event-driven decoupling via SNS/SQS pub-sub, independence and separate scaling of individual services.

E-Mobility Platform Architecture

Segregation of EMP (e-Mobility Provider) and CPO (Charge Point Operator) functionality. Platform architecture design with clearly separated responsibilities and bounded contexts.

Third-party System Integrations

Integrations with third-party systems in the e-mobility space — Hubject (roaming), Etrel (hardware) and SolidStudio CPMS. Protocols, mappings, error handling and monitoring.

Analytics Data Platform

Data lake creation for analytics, separation of analytical and production data, ETL pipelines in AWS Glue and Athena, reporting and dashboards.

About

I'm Michal Kurtulík — a software engineer and solution architect with many years of experience in software solution design and development, cloud architecture and infrastructure. I provide services independently under the Yonix.sk brand.

My work connects two worlds — software architecture and real infrastructure. I help companies design solutions that are not just pretty on a diagram, but actually work in production.
