PRODUCTION SYSTEMS PORTFOLIO · PROOF OF WORK

Documented AI Implementations & Proof of Work

I don't sell promises or generic slide decks. Here are 5 deeply documented production deployments with hard KPI metrics, architecture diagrams, and battle-tested code running across Polish and European enterprises.

Engineering Standard: All production systems detailed below operate live across commercial enterprises generating between $3M and $15M (10M–50M PLN) in annual turnover. Every deployment is delivered under a 100% code ownership model (Git/Docker), strictly enforcing deterministic zero-hallucination guardrails (Poka-Yoke) and direct integrations into ERP, PIM, and advertising APIs.

SECURITY & ARCHITECTURAL STANDARDS

Sovereign Enterprise Engineering: Zero Vendor Lock-In

All production systems are engineered under rigorous corporate data security standards, eradicating dependencies on closed SaaS subscriptions while protecting trade secrets.

§

EU AI Act 2026 Compliance

Direct API at Cost with Zero Data Retention (ZDR) clauses and Data Processing Agreements (DPA). AI model vendors never train on proprietary data.

⎘

100% Code Ownership (Git & Docker)

Complete source code, orchestration workflows, and container configurations belong to your enterprise. Zero per-user licenses, zero royalties.

☁

Cloud-Agnostic Architecture

Deployable across your infrastructure of choice: Google Cloud Platform, AWS, Microsoft Azure, private European VPS, or dedicated on-premise hardware.

✓

Poka-Yoke Determinism

Zero hallucinations across margin ledgers and inventory counters. Core business rules and financial mutations are locked inside deterministic Python logic.

⏱

SLA & Engineering Runbooks

Every deployment is handed over with complete technical runbooks and regression test suites, ensuring an absolute zero Bus Factor.
