Miz Causevic — // kineticgain

[ Director of Web Engineering & Platform Architecture ]
[ Boston, MA · 30 yrs of platform & web engineering ]
[ IBM · CyberArk · Alteryx ]

I build AI Platform Engineering infrastructure — the layer that sits between agents/models and the SRE, SecOps, FinOps, and platform teams who have to keep them running in production.


The Doctrine

Most enterprises ship AI features by stitching together notebooks, vendor consoles, and Slack channels. That works at demo scale. It does not work when you have 8 MCP servers, 12 agent fleets, 6 RAG collections, three model providers, a $50K monthly LLM bill, a CISO asking "are we OK right now," and a CFO asking "are we on budget."

This portfolio is a deliberate platform, not a pile of side projects. Nine repos. Nine surfaces. One doctrine: every layer of the AI stack needs the same governance discipline that database, network, and identity surfaces already have.


The Nine Repos

# Repo Surface Question it answers CI
1 mcp-sentinel Tool calls What MCP tools are exposed and how risky? CI
2 rag-sentinel Retrieval What is in the vector store and how trustworthy? CI
3 agent-codex Decisions Under what policies are decisions allowed? CI
4 agent-eval-arena Pre-prod Should this model promotion ship? CI
5 agent-router Runtime routing Which model does this request actually hit? CI
6 agentobserve Runtime telemetry What did agents actually do? CI
7 shadow-ai-detector Egress Who is leaking what to whom? CI
8 ai-finops-radar Finance Are we on budget — and why not? CI
9 kinetic-flightdeck Operator Are we OK right now? Who do I call? CI

Common Patterns Across All Nine

Every repo in this portfolio follows the same engineering discipline:

Pattern Why
TypeScript strict mode + Node.js 20+ Type safety + LTS runtime; same as enterprise platform teams
Express 5 + Zod schema validation Versioned, validated, swagger-able APIs
Composite scoring with override logic A 90 composite + one critical signal still blocks. "Platform thinking."
Heuristic-first analysis, LLM-judges optional Deterministic, testable, cheap - no judge LLM in the hot path
CI on Node 20 + 22 matrix Forward-compatibility before LTS deprecation
Local validation before push Sandbox build, npm test green, push only when green. Zero broken pushes since adopted.
BERT dark theme + JetBrains Mono / Space Grotesk Operator dashboards that do not look like SaaS demos
Composite + per-signal + recommended-action output shape What an SRE pager-rotation actually needs to read at 3am

What This Portfolio Demonstrates

For platform-engineering / director-level hiring managers:

  • Range across the AI stack - tool calls, retrieval, decisions, eval, routing, runtime observability, egress, finance, operator surface. Nine perspectives, one doctrine.
  • Three buyer profiles - CTO/Platform (mcp-sentinel, agent-codex, agent-router, agentobserve, kinetic-flightdeck), CISO (shadow-ai-detector, mcp-sentinel), CFO (ai-finops-radar). One coherent platform thesis.
  • Production-minded backend design - strict TypeScript, schema validation, full test coverage, CI matrix, dashboards as deliverables.
  • Enterprise-ready domain modeling - auth posture, OAuth scopes, SOC 2 / EU AI Act mapping, PII patterns, compliance frameworks, accountability rollups, anomaly detection, forecasting with confidence intervals.
  • Refusal of demo-quality engineering - none of these projects has placeholder logic. Every aggregator is testable, every override rule is justified, every composite score has weights chosen for a reason. Circuit breakers have correct half-open semantics.
  • Platform-thinking doctrine - no project ships without a governance loop, an operator output, and override logic that respects single-signal escalation. The same discipline applied across nine different problem domains.
