# Igor Klepacki

When I was 10 years old I created my first computer program on my father's Windows XP: a VBScript infinite loop displaying message boxes captioned “hey u got hacked!”.

Today I am a software engineer with more than five years of experience building production software end-to-end, from front-end and back-end systems to cloud infrastructure and deployment. My work focuses on Next.js at scale, especially e-commerce, developer tooling, and AI-powered applications. I have also worked closely with enterprise clients, providing technical guidance and architectural support.

My interests extend beyond software engineering into networking, operating-system internals, distributed systems, and digital forensics. Outside technology I enjoy cinematography, photography, applied physics, books and novels—especially science fiction—and studies about dogs, with my best friend Gen (秋田犬).
