AI Architecture Case Studies

Real-world problems I've architected solutions for. Each case study shows the business challenge, the architectural approach, and measurable outcomes.

MegaDoc is the reference implementation validating these patterns in production.

🎯
Problem First Start with business pain, not technology
⚖️
Trade-off Transparency Every decision has documented rationale
📊
Measurable ROI Quantified outcomes, not promises
🔒
Security by Design Privacy-first, not privacy-bolted
CASE STUDY: LEGAL

Contract Analysis & Red-lining

The Challenge

Legal teams spend 40+ hours per week reviewing contracts manually. AI assistants hallucinate clause interpretations, creating compliance liability. No audit trail for regulatory review.

Architecture Decision

Legal Domain Profile with zero-hallucination enforcement. Every response must cite source clause. RAG pipeline with mandatory context validation before generation.

  • Clause extraction with mandatory citation
  • Zero-hallucination domain profile
  • Risk flagging for ambiguous terms
  • Full audit trail for compliance
MEASURED OUTCOME
70% reduction in review time • 95%+ accuracy on clause extraction • 100% citation traceability

CASE STUDY: FINANCE

Audit & Fraud Detection

The Challenge

Manual audit preparation takes weeks. Anomalies hide in thousands of documents. Regulators require complete evidence trails that manual processes can't guarantee.

Architecture Decision

Multi-modal document pipeline with structured data extraction. Pattern analysis layer for anomaly detection. Immutable audit trail with cryptographic hashing.

  • Financial statement extraction
  • Transaction anomaly detection
  • Regulatory compliance review
  • Cryptographic audit trail
MEASURED OUTCOME
60% faster audit prep • 3x more anomalies detected • Full regulatory trail

CASE STUDY: HEALTHCARE

Diagnostic Support Assistant

The Challenge

Clinicians need to cross-reference imaging with patient records quickly. Generic AI risks HIPAA violations. Safety-critical context requires evidence-based responses only.

Architecture Decision

Medical Domain Profile with safety-first guardrails. Vision RAG for imaging analysis. Automatic PII redaction before any model inference.

  • Vision RAG for medical imaging
  • HIPAA-compliant PII redaction
  • Safety guideline prioritization
  • Evidence-based responses only
MEASURED OUTCOME
40% faster triage • 99.9% PII redactionZero PHI in model prompts

CASE STUDY: INDUSTRIAL

Predictive Maintenance

The Challenge

Unplanned downtime costs $100K+ per hour. Field technicians can't access manuals offline. Error codes need exact part numbers, not AI speculation.

Architecture Decision

Technical Domain Profile with specification accuracy. Vision defect detection. Offline-capable with cached embeddings for field deployment.

  • Visual defect analysis
  • Error code → part matching
  • Technical manual retrieval
  • Offline-capable deployment
MEASURED OUTCOME
25% less downtime+18% first-time fixWorks offline

CASE STUDY: AI AGENTS

Document Processing for AI Agents

The Challenge

AI agents need structured document access but most platforms require human mediation. LangChain and Claude integrations lack standardized document tools. CI/CD pipelines can't automatically process document artifacts.

Architecture Decision

MCP/REST layer enabling AI agents to treat MegaDoc as a first-class document tool. Stateless API design for horizontal scaling.

  • MCP server integration for AI agents
  • LangChain-compatible REST API
  • CI/CD pipeline automation
  • Agentic workflow document tools
MEASURED OUTCOME
10x faster document processing vs human • Zero manual intervention for standard docs • API-first for any agent framework
🤖 AI Agent / LangChain
⚡ MCP / REST API
📝 Structured Document Data
🧠 Agent Processing
✅ Autonomous Task Complete

AI Agent → Document Tool → Structured Data → Action

CASE STUDY: KNOWLEDGE

Enterprise Knowledge Hub

The Challenge

Knowledge scattered across Confluence, SharePoint, Git, and runbooks. New engineers take 3+ months to onboard. 80% of Slack questions are answerable from existing docs.

Architecture Decision

Unified Knowledge Graph with RAG-based search and mandatory citations. Cross-platform indexer with deduplication.

  • Unified search across wikis, tickets, and code docs
  • Architecture decision record (ADR) explorer
  • Onboarding assistant with real internal docs
MEASURED OUTCOME
50% faster onboarding • 80% of questions answered without Slack • Single search across all systems
🛡️
CASE STUDY: GRC

Policy & Control Mapping

The Challenge

Auditors require evidence linking regulations to internal controls. Manual gap analysis takes weeks. Policy documents become stale without continuous mapping.

Architecture Decision

Policy-to-Control Mapping Engine linking GDPR, ISO, SOC 2 to internal controls. Automated evidence collection from documents and tickets.

  • Natural language policy queries with citations
  • Regulatory gap analysis automation
  • Evidence collection from tickets and docs
MEASURED OUTCOME
75% faster evidence gathering • Automatic gap analysisAlways audit-ready
💬
CASE STUDY: SUPPORT

Multi-Channel Support Assistant

The Challenge

Support agents spend 40% of time searching for answers. Similar incidents get different responses. Escalation happens too late due to missed sentiment signals.

Architecture Decision

Multi-Channel Intelligence Layer ingesting tickets, chats, and FAQs. Sentiment-aware escalation signals with similar-incident matching.

  • Suggested responses with source references
  • Automatic ticket categorization
  • Sentiment-based escalation signals
MEASURED OUTCOME
35% faster handle time • 20% deflection to self-service • CSAT +12 pts
