Portfolio

Applied AI project case studies

Each case study connects an implementation choice to the human or organizational problem it is meant to solve.

Development Knowledge Vault

Independent R&D · 2026

Development Knowledge Vault

An MCP server that serves distilled engineering patterns to AI coding agents, so a new project reuses prior deploy, auth, and eval practices instead of rediscovering them.

LLM Reasoning with Human Decisions & PII Masking

Independent R&D · 2026

LLM Reasoning with Human Decisions & PII Masking

InSummery.AI

A multi-agent scheduling concierge that masks PII before inference and pauses for a human when its confidence drops below 80%, turning messy family email into a reconciled calendar.

  • Google ADK 2.0
  • Python
  • Pydantic
Multi-Agent Market Intelligence Ecosystem

Independent R&D · 2025-2026

Multi-Agent Market Intelligence Ecosystem

OpenClaw Multi-Agent Market Intelligence Ecosystem

An autonomous research framework whose agents keep durable memory across interrupted tasks and stop for human approval before any high-stakes database commit.

  • OpenClaw
  • Python
  • SQLite
AgentOS: Chief of Staff Agent

Independent R&D · 2025-2026

AgentOS: Chief of Staff Agent

A multi-agent orchestrator with modular subagents and mandatory human checkpoints, built so long-running workflows can be paused and inspected rather than trusted blindly.

  • Cursor Agent SDK
  • Python
Stack Overlord

Independent R&D · 2026

Stack Overlord

A CI/CD command center that catches silent post-merge deployment failures—ingesting signed GitHub webhooks into a durable Postgres ledger and diagnosing failures with cited, confidence-scored GPT-5.6 analysis that never overrides GitHub's own pass/fail verdict.

  • Codex
  • GPT-5.6
  • Next.js
