Who I Am

I'm Mykola Kpi, a passionate software developer with expertise in modern web technologies. I graduated from Kyiv Polytechnic Institute in 2015, where I developed a strong foundation in computer science and software engineering principles.

Technical Expertise

My primary focus areas include:

  • PHP Development - Building robust web applications and APIs
  • Golang Development - Creating high-performance, scalable services
  • Web Technologies - Full-stack development with modern frameworks
  • DevOps & Infrastructure - Deployment and system administration

Why DevTinyTools?

As a developer, I often found myself needing quick access to various tools for daily tasks - JWT debugging, JSON formatting, color conversions, and more. Instead of searching through multiple websites or installing local tools, I decided to create a comprehensive collection of developer utilities that are:

  • Fast & Reliable - No server processing delays
  • Privacy-Focused - All processing happens in your browser
  • Always Available - No registration or installation required
  • Mobile-Friendly - Works perfectly on all devices
