About Me
Hi! I'm Sergiy, aobackend/full‑stack developer with 8 years of experience in Laravel and PHP. I work as an independent developer under the DevRhino brand.
Over the years I've covered the full development lifecycle: websites, web applications, e‑commerce solutions, SaaS platforms, and business automation systems. I use Laravel, PHP, and modern web technologies, along with AI‑assisted tools to speed up development.
I put strong emphasis on application architecture: separating business logic from infrastructure code, applying design patterns, SOLID principles, and Domain‑Driven Design (DDD) to keep the product structured, maintainable, and easy to scale.
