DevLog & Showcase
Hi, I’m Sergey. I build reliable AI systems and maintainable web platforms.
AI and backend engineer working with local LLMs, coding agents, model evaluation, Python, PHP, Node.js, and WordPress.
I focus on explicit contracts, reproducible evaluation, observable runtime behavior, and tools that work beyond a demo.

Debugging Local LLM Benchmarks: Aider, llama.cpp, and Runaway Output
A practical account of building a fair local-agent benchmark, debugging reasoning-model serving, fixing greedy-decoding loops, and adding an exact-repetition circuit breaker to llama.cpp.

From “No Docker” to “Trust Boundaries”: How an AUR Supply-Chain Attack Changed My View of Local Development Environments
A few months ago I wrote an article describing my local PHP and WordPress development setup on Arch Linux. The idea was simple: one command → working project No Docker.No containers.No extra abstraction layers. Just native Linux services: For a long time it worked exactly as intended. Fast.Simple.Predictable. I still believe the technical solution itself…
Zero-config local PHP/WordPress development environment on Arch Linux (without Docker)
• One nginx config • One SSL certificate • Dynamic project routing • One command project bootstrap Result: new PHP project in ~5 seconds.
Why I Moved to Arch Linux
I didn’t switch to Arch Linux because it’s better in some absolute sense.And not because other distributions are worse. At some point, I just noticed that I wanted fewer ready-made answers. Before that, I was on CachyOS.It worked well. It was fast, comfortable, and mostly invisible.That was useful — especially when I didn’t want to…
