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.

    paper JobAI Platform (Side Project - In Development)
    • 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.
