Available to hire
Senior full-stack engineer with 7 years of production experience building trusted AI systems for agentic workflows. I focus on evidence-first execution, deterministic replay, schema contracts, and auditable human approval states across data-rich React interfaces and reliable APIs.
Recent work includes deploying a healthcare AI audit tool for denial-review with append-only event logs and safe replay, building forensic investigation workflow control for agent runs, and architecting real-time show-control and service-oriented creator platforms using NestJS/PostgreSQL/Kafka patterns.

Work Experience
Developer at Flow Profile (Auditable Context Bundles for AI Assistants)
January 1, 2026 - PresentCreated a redaction-first pipeline to produce share-safe, deterministic context bundles. Uses SARIF risk detection, token budgeting, and content-addressed deterministic outputs. Provides both CLI support for CI/CD and a Vue UI for human audit workflows.
Developer at Vifei Suite (Deterministic AI Agent Replay Engine)
January 1, 2026 - PresentBuilt a deterministic AI agent replay evidence pipeline in Rust using canonical commit_index ordering and multiple evidence lenses, producing fail-closed share-safe exports. Demonstrated deterministic replay by generating matching canonical SHA-256 evidence artifacts without relying on live model calls.
Builder / Engineer at Denial Review Workbench
January 1, 2026 - PresentBuilt a deployed AI audit tool for healthcare denial-review teams to speed workflows without sacrificing trust. Implemented a constrained multi-call pipeline with append-only JSONL event logs and read-only replay to reconstruct approval state without re-invoking the model. Deployed React + FastAPI + Anthropic with Ansible, SOPS-encrypted secrets, systemd, and Caddy TLS; improved escalation behavior to suppress draft/approval when policy ambiguity is detected.
Architect / Engineer at MissionRelay
January 1, 2026 - PresentArchitected a NestJS service-oriented creator platform with event-sourced PointsLedger over PostgreSQL, Redis Pub/Sub for WebSocket fanout, and a Kafka outbox pattern for durable lifecycle events. Wrote design and testing foundation docs (PLAN.md, AGENTS.md, CONTRACT.md). Shipped a mobile vertical slice validating OTP, JWT refresh rotation, RBAC, and mission/submission lifecycle, along with documented API endpoints.
Run Contracts & Agent Workflow Control (Implementation Contract Definition) at Vipernauts
January 1, 2026 - PresentDefined a run contract pattern for high-stakes agentic workflows including intent, context ledger, spec/YAML validation, tool timeline, evidence panel, replay status, approval gates, and receipt export. Converted schema/doc/runtime drift into reviewable implementation contracts and established typed failure states and human approval gates for analyst-style workflows.
Auditable Context Bundle Tool at Flow Profile
January 1, 2026 - January 1, 2026Created a redaction-first pipeline that generates safe-to-share, deterministic, content-addressed context bundles for AI assistants. Uses SARIF risk detection and token budgeting to prevent leakage of credentials/secrets/PII in plaintext. Includes CI/CD CLI and a Vue 3 UI for human audit; identical inputs produce byte-identical outputs.
Deterministic AI Agent Replay Engine (Rust) at Vifei Suite
January 1, 2026 - January 1, 2026Implemented a deterministic evidence pipeline for AI agent runs using a Rust multi-crate workspace. Created canonical commit_index ordering and a tiered truth protection/evidence lens workflow to provide fail-closed, share-safe exports. Demonstrated deterministic replay by producing matching canonical SHA-256 files without relying on live model calls.
Built and Deployed AI Audit Tool at Denial Review Workbench
January 1, 2026 - January 1, 2026Built a healthcare denial-review AI workbench to produce auditable, replayable approvals without re-invoking the model. Implemented a constrained multi-call pipeline using append-only JSONL event logs and read-only replay that reconstructs approval state. Delivered React + FastAPI + Anthropic deployment using Ansible, SOPS-encrypted secrets, systemd, and Caddy TLS. Implemented escalation behavior to suppress draft/approval controls when policy ambiguity is detected.
Architected Service-Oriented Creator Platform at MissionRelay
January 1, 2026 - January 1, 2026Architected a NestJS backend with event-sourced mission state via PointsLedger on PostgreSQL, Redis Pub/Sub for WebSocket fanout, and a Kafka outbox pattern for durable lifecycle events. Authored PLAN.md, AGENTS.md, and CONTRACT.md as design/testing foundations. Shipped an Expo + FastAPI mobile vertical slice validating OTP, JWT refresh rotation, RBAC, and mission/submission lifecycle plus multiple documented API endpoints.
Run Contracts & Agent Workflow Control (Project Work) at Vipernauts
January 1, 2026 - January 1, 2026Defined a run contract pattern for high-stakes agentic workflows including intent, context ledger, spec/YAML validation, tool timeline, evidence panel, replay status, approval gates, and receipt export. Documented and separated shipped patches, prepared patches, read-only findings, and decision blockers to turn schema/doc/runtime drift into reviewable implementation contracts with typed failure states and evidence bundles.
Developer at Agent Cassette (Record/Replay Engine for AI Agent Sessions)
January 1, 2025 - PresentImplemented a record/replay harness capturing every LLM call and tool invocation as append-only JSONL. Replay mode blocks side effects and returns saved responses, enabling CI runs without an API key and at near-zero cost.
Record/Replay Engine for AI Agent Sessions at Agent Cassette
January 1, 2025 - January 1, 2025Built a record/replay harness capturing every LLM call and tool invocation as append-only JSONL. Replay mode blocks side effects and returns saved responses. Enabled CI runs without an API key by returning saved responses at effectively zero runtime cost/token usage.
Platform Engineer (Open Source) at Ithi / OSLabs
January 1, 2024 - PresentCo-shipped an AI-powered VS Code extension. Owned AST-aware identifier masking with two-pass restoration, and built a secure React webview bridge using nonce-based CSP plus typed messaging to prevent XSS. Developed a pluggable translation layer with provider fallbacks and rate-limit handling across OpenAI, Bing, and Google Cloud. Built Zodia, a RAG application over structured documents with schema design, embedding pipeline, and REST API ownership.
Contract Software Engineer at Vipernauts (SpeakToJade, ScamDOX)
January 1, 2024 - January 1, 2026Hardened the private platform engine behind investigation workflows. Authored foundational specs (Spec.md, Skills.md), implemented/maintained a MultiStepExecutor and stage-name sanitization with tests and fuzz coverage, integrated eBPF syscall observability, and patched token-boundary context overflow. Separated load-time vs runtime failures, isolated evidence custody-related follow-ups, and addressed loader/runtime drift that could silently skip task runs due to shape mismatches. Prepared deletion-flow patch using Prisma metadata and built a Slack approval cockpit prototype for artifact routing, strengthening schema contracts, safe error boundaries, replay receipts, and evidence traceability.
Platform Engineer (Open Source) at Ithi / OSLabs (Open Source)
January 1, 2024 - PresentCo-shipped Ithi, a VS Code extension on the Visual Studio Marketplace. Owned AST-aware identifier masking with two-pass restoration preserving syntax, and a React webview bridge with nonce-based CSP plus typed messaging to reduce XSS risk. Built a pluggable translation layer with provider fallbacks and rate limiting across OpenAI, Bing, and Google Cloud. Developed Zodia, a React/TypeScript RAG application over structured documents with schema design, embedding pipeline, and REST API ownership.

January 1, 2018 - January 1, 2024Designed distributed real-time show-control systems and Node.js sensor pipelines for interactive brand activations. Built React Native controller apps that helped non-technical operators run cue stacks from smartphone controls for major productions. Architected Resofleur and Aliveca, modular real-time visual-engine runtimes with fault-tolerant execution, GPU/CPU fallback, and supervised crash recovery. Standardized deployments across venues, reducing installation effort and improving render latency while supporting unattended multi-hour runs.
