01 / PROFILE

About

I am an AI Engineer and LLM expert with 7+ years of experience building high-traffic web applications in production-grade environments.

I work on RAG, LangGraph, MCP, semantic search and AI automation, connecting Python, FastAPI, Elasticsearch, Qdrant and real full-stack systems.

PHP/Symfony, React, Docker, GitLab CI/CD, Ansible, OpenTelemetry, Sentry and Zabbix are the operational base I use to ship reliable systems.

05 / METHOD

How I work

01 I start from the operational problem, not from the loudest technology.
02 I design production-grade solutions with clear control points: logging, tracing, metrics and fallbacks.
03 I measure performance, scalability, maintenance cost and impact before calling work done.
