Serhii Nikolaienko
Founder of Seganiko, full-stack developer and digital solutions architect since 2012. I design web platforms, custom CRM systems and e-commerce stores that deliver measurable results — not just code.
Passionate about artificial intelligence and its practical applications, I integrate AI assistants, chatbots and automation tools into my clients' projects. I believe technology should simplify life, not complicate it.
My expertise: WordPress & WooCommerce, custom CRM, AI integration, technical SEO, complex systems architecture.
Beyond code, I'm a curious and versatile person. I love hiking in the mountains, observing nature and stargazing — moments that fuel my creativity and my ability to see things from a different perspective.
Based between France and Luxembourg, I help businesses across Europe and internationally with their digital transformation.
