Fusion UX Doctor is an AI-powered webpage auditor built entirely in Fusion by Builder.io (http://Builder.io). Paste any URL and instantly get a complete UX, Accessibility, and Performance analysis, followed by AI-generated layout improvements built as real Fusion components. This project creatively uses Fusion’s visual canvas to turn audits into an interactive experience with animated cards, a clean Before/After comparison, and on-canvas component regeneration. The innovation lies in how AI doesn’t just evaluate a design, it rebuilds it directly in Fusion, proving what’s possible when design, code, and intelligence come together.

RAMP-SENTINEL is a Tier-0 Compliance Architecture designed for the FinTech and Crypto sectors. This document is a redacted portfolio version of the Master Blueprint, showcasing an autonomous Level-2 Anti-Money Laundering (AML) investigator swarm. The primary achievement of this architecture is the elimination of the "Black-Box" liability. It replaces opaque machine learning risk scores with a transparent, deterministic graph traversal trail. By mechanically linking fiat ledgers with on-chain cryptographic data, the system drafts mathematically verified Suspicious Activity Reports (SAR) that meet the strict requirements of financial regulators (FCA, SEC, KNF). [ARCHITECTURAL IP & LIABILITY NOTICE] This document is a redacted sample of a Master Engineering Blueprint. It is intended exclusively for demonstrating architectural methodology and strategic framework design. It does not constitute a completed engineering source of truth for any third-party production environment. All proprietary frameworks and "Zero-Trust Fail-Safe" methodologies contained herein are the exclusive intellectual property of Łukasz Bazan. As a Fractional Architect, I provide the "Engineering Brain." I do not perform direct application coding. Any attempt to implement these patterns by internal teams is done at the Client’s own risk.

PAY-SENTINEL is a highly deterministic architectural framework designed to eliminate financial leakage in FinTech refund and payment automation pipelines. This document is a redacted portfolio version of the Master Blueprint, demonstrating how to replace probabilistic "AI Wrappers" with hard, stateful logic. The primary achievement of this architecture is the complete eradication of "Semantic Drift" and False Approval Rates (FAR). By weaponizing Pydantic V2 and GraphRAG, the system incarcerates stochastic AI outputs within rigid JSON schemas, forcing 100% SLA and KYC compliance before any transaction API is triggered.

CYBER-AEGIS is a proprietary Tier-0 architecture designed for Enterprise Security Operations Centers (SOC). This document is a redacted portfolio version of the Master Blueprint, showcasing an autonomous SOC Swarm engineered to eliminate Alert Fatigue and probabilistic hallucinations. The primary achievement of this architecture is the mechanical grounding of SIEM logs within a Zero-Trust Knowledge Graph (Neo4j). By utilizing OCSF normalization and a LangGraph Swarm, the system compresses the Mean Time To Detect (MTTD) for complex threats from days to sub-minute resolution, algorithmically rejecting over 90% of false-positive noise before human escalation.

NEXUS-FORGE is a proprietary Tier-0 architecture designed for global supply chains operating on enterprise-grade ERP systems (SAP/Oracle). This document is a redacted portfolio version of the Master Blueprint, which eliminates the risk of "Stochastic Deadlock" and API Exhaustion by implementing an Asynchronous Sidecar pattern. The primary achievement of this architecture is the transformation of unpredictable AI forecasts into a deterministic "Digital Twin" model powered by a Neo4j Knowledge Graph. This enables the prediction of cascading failures and the calculation of a logistical "Blast Radius" with mathematical precision, completely isolating core operational databases from probabilistic AI models.
