Freelancer profile translated to English.

Description

I am a Senior Software Engineer and Software Architect (MSc, MBA) with over 15 years of hands-on experience in developing production-ready systems in finance, media, and SaaS. My background includes backend development, enterprise integrations, search and information retrieval, and security, with deep expertise in JVM ecosystems, TypeScript/Node.js, and Python.

Currently, my focus is on AI Engineering, with practical experience in building RAG and LLM-based applications, integrating OpenAI APIs, and developing retrieval, prompt, and tool workflows. I bring a pragmatic, engineering-driven approach to ingestion pipelines, retrieval workflows, structured testing, and production-ready automation, supported by documentation of configurations, processes, and results.
