About

Product-oriented Software Engineer with 10+ years of experience designing, building, and scaling
web platforms across diverse domains, now pivoting toward the development of GenAI-powered
products. My background spans full-stack engineering, APIs, cloud infrastructure, and clean
system design, which I now leverage to build applied AI solutions rather than isolated prototypes. I
focus on Python (FastAPI), modular and hexagonal architectures, and the implementation of
LLM-based systems, including RAG pipelines, multi-agent workflows, and AI-driven automation.
My current objective is a deliberate transition toward AI product development, combining
long-term engineering expertise with newly acquired and continuously consolidated skills in
GenAI, applied machine learning, and MLOps. I am particularly motivated by environments where
experimentation meets real-world constraints, and where AI solutions must be robust, traceable,
and production-ready from day one.

  • GenAI platform currently under active development for intelligent job search
    automation using LLMs and RAG architecture.
  • Designed with hexagonal (ports & adapters) architecture to ensure clean separation
    between domain logic, AI workflows, and infrastructure components.
  • Ongoing implementation of multi-agent workflows for CV parsing, job matching,
    cover letter generation, and recruiter-style feedback.
  • Development of retrieval-augmented generation (RAG) pipelines with vector
    embeddings for semantic search over job offers and candidate profiles.
  • Backend architecture built with FastAPI, async processing, and modular AI services,
    designed for experimentation and future production scaling.
  • Exploration of LLM orchestration patterns (prompt routing, tool calling, evaluation
    loops) inspired by LangChain / LangGraph.
  • Dockerized development environment with CI-ready structure, focusing on testability,
    traceability, and evolvability of AI systems.

Tech stack: Python, FastAPI, LLMs (OpenAI-compatible), RAG, Vector Search, Hexagonal
Architecture, Docker, CI/CD
