Back to original languageAbout Vladyslav
I am a backend developer specializing in administrative data management systems and architectures that connect historical business software to modern platforms.
My experience covers two often separate universes:
- Existing business applications (WinDev, Access databases, software used by local authorities)
- Modern architectures (Python, APIs, PostgreSQL, Docker, web interfaces)
This dual expertise allows me to work on different types of projects:
- maintenance and evolution of existing business software
- development of modern backend services
- integration of data from historical systems
- design of architectures for progressive modernization of existing tools
I particularly focus on projects requiring the structuring and exploitation of complex data from multiple sources.
I also master the secure deployment of applications via Docker, Nginx, and Certbot / Let’s Encrypt, ensuring robust and maintainable services.
