About Me

Hi, I’m Sergey — an AI and backend engineer building reliable systems around local LLMs, coding agents, and web platforms. My background is in PHP, WordPress, Laravel, APIs, databases, and infrastructure. That foundation shapes how I approach AI systems: explicit contracts, reproducible evaluation, observable runtime behavior, and tools that work outside a demo.

My current work focuses on local model serving, agent workflows, benchmark and evaluation pipelines, retrieval and embeddings, and developer tooling. I care less about adding AI as a feature than about making model-backed systems measurable, maintainable, and useful.

I still build and optimize web platforms, because reliable AI engineering depends on the same fundamentals: clear architecture, controlled deployments, secure infrastructure, and honest performance data.
