Selected engineering evidence

Concrete systems, measurable results.

Visible Network Labs · data pipelines

~10 minutes to ~10 seconds

Data pipeline performance

Reduced processing time for a production CSV import by removing N+1 query patterns, batching database operations, memoizing repeated lookups, and hardening edge-case parsing.

Graph Interfaces

Visible Network Labs · graph interfaces

Up to ~5K nodes / ~20K edges

Interactive graph systems

Built Vue, TypeScript, D3.js, and Apache ECharts interfaces for relational datasets, with dynamic filtering, styling, grouping, and performance work for large network graphs.

Evaluation & Reliability

Independent work · evaluation & reliability

Replayable agent evaluation

Agent workflow evaluation

Built a nine-node typed LangGraph pipeline with structured Pydantic validation, weighted model-assisted scoring, policy filtering, versioned prompts, and replay fixtures that produce per-node audit traces plus reliability, cost, and latency metrics per run.

Professional experience

Production product work and current independent engineering.

- Present

Agent systems · evidence tooling · internal applications

Current work: EvidEngine, VimCommander, a typed LangGraph evaluation workflow, and FastAPI-backed internal applications.

  • Implemented typed LangGraph workflows that separate state, model calls, scoring, policy checks, selection, and replay evaluation, with per-node traces and run metrics.
  • Built FastAPI-backed internal applications with validated contracts, persistent data models, audit trails, and automated test coverage.
  • Developed provenance-aware evidence and retrieval tooling with deterministic artifacts, stable identifiers, exact/BM25 lookup, graph traversal, optional Neo4j integration, and MCP tools.

-

Data pipelines · graph interfaces · enterprise auth

Full-stack product engineering for data-heavy network-analysis applications.

  • Reduced a production CSV import from roughly 10 minutes to roughly 10 seconds by removing N+1 query patterns, batching database operations, memoizing repeated lookups, and hardening edge-case parsing.
  • Built Vue, TypeScript, D3.js, and Apache ECharts interfaces for relational datasets, including dynamic filtering, styling, grouping, and performance work for large network graphs.
  • Implemented SAML 2.0 single sign-on and granular, role-scoped authorization for complex data-access roles and permissions.
  • Built and maintained unit and end-to-end test infrastructure with GitHub Actions pre-merge checks for data-heavy application workflows.

Flagship projects

Current work in evidence systems and developer tools.

Agent Systems

Evidence tooling · v0.1.0

EvidEngine

Local-first evidence-graph tooling that turns documents, configuration, source anchors, and Git history into source-traceable artifacts, so what an agent retrieves can be cited back to the exact document, line range, or commit it came from.

View EvidEngine overview
  • Implemented deterministic ingestion, extraction, linking, indexing, and query stages with stable identifiers and explicit run artifacts.
  • Modeled documents, segments, passages, entities, relationships, files, commits, and authors with provenance and precise source locators.
  • Added BM25 keyword search, exact-key lookup, graph traversal, optional Neo4j export and synchronization, and Model Context Protocol (MCP) tools.
  • Designed source-code ingestion around addressable symbol and line-range anchors, giving code review and software-delivery (SDLC) automation auditable provenance.

Status: CLI-first developer tool in early-stage development (v0.1.0); exact-key and BM25 search by default, with experimental semantic retrieval.

Developer Tools

Developer tools · active development

VimCommander

A browser space shooter built with React, TypeScript, and a full automated test suite, designed to teach Vim commands through keyboard-driven gameplay.

Open VimCommander live build
  • Built the game with TypeScript, React, Phaser, Three.js, Zustand, Zod, Vite, and Vitest.
  • Separated keyboard semantics from game behavior through an engine-independent mapping layer that routes high-level Vim actions.
  • Modeled editor modes and transitions with a pure, deterministic finite-state machine.
  • Used JSON Schema-defined bindings and shared game-client contracts to support alternate clients and control systems.
  • Added automated unit and integration tests for mappings, state transitions, user interface behavior, and game systems.

Status: active development.
