Applied AI portfolio
A model is one part of a useful product. My independent work connects extraction, context, tools, evaluation, privacy and human review. Explore the systems I build, the ideas I publish and the broader 100+ app portfolio behind my product practice.
Personal projects and technical practice
I build through LaunchDesk LLC, founded in 2026. The work below distinguishes application features, independent experiments and educational tools.
Evidence and evaluation
An extracted answer needs evidence.
Financial-email workflows turn receipts, bills, renewals and refunds into actions. I built source-evidence validation and a 61-case deterministic regression suite. An optional structured LLM extraction hook requires claims to match source-text anchors.
Explore KaiInboxAI privacy and operational controls
Protect sensitive information before a model sees it.
I implemented PII detection and policy checks before model-provider calls, tenant-scoped routing, circuit-breaker fallback and audit records, with an offline labeled corpus for detector validation. Sanctuary Browser Guard previews, redacts and blocks sensitive prompts before they leave the browser.
Explore the app listingAgentic software delivery
Make agent workflows reviewable from discovery to release.
My personal project spans discovery, architecture, coding, testing, deployment and operations, with human review, approvals and executable checks. I explore MCP for tool and data access and A2A for coordination, with explicit permissions.
AI-generated software
Give generated code an accountable path to release.
I built educational CI checks for AI-generated pull-request evidence, protected paths, release-risk classification and generated-test review. The work complements my writing on traceability, testing and human oversight.
Read AI Code GovernanceIndependent prototype
Put explicit limits around an agent’s authority.
My agent-payment protocol prototype uses simulated payment rails, delegated authority, spending limits, approvals and deterministic replay. It provides a sandbox for exploring agent authority, transaction controls and accountability.
Educational tooling
Evaluate outcomes and tool behavior before release.
I built an educational Python evaluation toolkit covering outcome grading, tool-policy checks, paired comparisons and release gates. It makes the evaluation criteria and release decision explicit.
Applied AI focus
These areas connect my production AI integration, independent implementations and technical publications.
LLM applications and inference
Generative AI, retrieval-augmented generation, vector search, embeddings, prompt and context engineering, and state and memory management. My technical writing also covers inference efficiency through model routing, caching and latency-cost tradeoffs.
Agent architectures and evaluation
Multi-agent orchestration, LLM harnesses, planner-executor and reviewer patterns, tool calling, scenario-based evaluations, regression testing, observability and failure recovery.
AI security and governance
Human-in-the-loop oversight, least-privilege permissions, data boundaries, sandboxing, prompt-injection defense, auditability and staged deployment.
