About Me

My name is Oleksii Ivanov, and I’m a Senior Software Developer specializing in PHP and backend architecture. Over the years, I’ve designed, built, and maintained production systems ranging from lean MVPs to large-scale, high-traffic applications. My work centers on writing clean, maintainable code and building systems that remain stable under real-world pressure.

This blog is where I document what I learn, refine, and occasionally challenge. You’ll find articles on PHP internals, modern frameworks, software architecture, performance optimization, API design, testing strategies, DevOps workflows, and practical engineering trade-offs. I’m particularly interested in:

• Scalable backend design
• Domain-driven design (DDD)
• Clean architecture principles
• Performance tuning and profiling
• Refactoring legacy systems
• Automated testing and CI/CD pipelines

I believe good software engineering is less about clever tricks and more about clarity, consistency, and sound decision-making. Most problems in mature systems are architectural, not syntactical - and solving them requires discipline, not hype.

Everything I share here is based on hands-on experience: real production constraints, technical debt, deadlines, trade-offs, and the lessons that come with them.

If you’re building serious backend systems or trying to move from “it works” to “it scales” - this blog is for you.
