Portfolio


  • Transport Intelligence

    Information Gathering
    The transport industry loses approximately €8.2 billion annually due to cargo theft, carrier fraud, and contractor bankruptcies (data from the European Parliament). Freight forwarders, cargo insurers, and leasing companies lack a tool that connects data from 33 countries in real-time and translates it into specific GO / NO-GO decisions. Multi-agent OSINT system with hierarchical orchestration: 1 Master Supervisor → 33 Country Supervisors → 71 specialized agents. Each agent has its own role: RSS readers, web scrapers (Scrapy + Playwright for SPA), forum agents, news aggregators, registry agents. NLP pipeline in 26 languages with Claude API. Decision layer with risk verdict per route, contractor, cargo.

  • GabinetyPl / Physioapp

    AI & Machine Learning
    GabinetyPl / Physioapp — example of freelancer's portfolio work in category AI & Machine Learning
    The GabinetyPL architecture is reusable for every type of medical office. The first vertical (PhysioApp) confirms the pattern. Other potential industries where we can quickly build a dedicated module include: cosmetology / SPA, veterinary medicine, psychology / psychotherapy, speech therapy / speech therapy, aesthetic medicine, massage / sports physiotherapy. Each new vertical = 3-5 working weeks instead of 8-12.
    Most "AI in medicine" are wrappers for external LLMs. PhysioApp takes a different approach because medical data has special requirements: GDPR/HIPAA-equivalents prohibit data leakage to external APIs without patient consent, determinism is crucial in clinical decisions (the therapist must know why the system suggested a specific palpation point), and auditability helps in legal disputes. An expert system with a structured knowledge base meets all three requirements — and is cheaper to maintain than 100k+ requests to Claude/GPT monthly.
