I’m a software engineer focused on building robust backend systems with Go, Domain-Driven Design (DDD), and clean architecture.

I care about systems that are correct, scalable, and maintainable — not just trendy. My work spans backend engineering, distributed systems, and AI-driven automation. Recently, I’ve been exploring AI engineering, local LLMs, and autonomous agents to solve real-world problems.

Beyond coding, I write articles about tech engineering and mathematics — breaking down complex ideas into practical understanding. I believe strong math foundations sharpen software design.

I also build and share open-source software, reusable snippets, and experiments on GitHub. Building in public keeps thinking sharp and engineering honest.

Here, I share:

Live coding sessions
System design & DDD discussions
AI experiments & agent workflows
Engineering + math articles
Open-source tools and practical code

No hype. Just serious engineering, deep thinking, and continuous building.
