B2B Technical Program Manager — Technical Leadership · Platform Architecture · AI Agent Systems

I turn customer requirements and technical constraints into development scope, architecture decisions, and working systems. Over 15 years, I have led B2B projects across manufacturing, healthcare, and enterprise platforms.

Alongside project leadership, I build AI agents and open-source tools for code search, specification, and review workflows. I use these tools in my current work to evaluate where they help—and where they fall short.

• legacy-spec-agent — Claude Code / Codex plugin that generates citation-backed (path:line) specifications from legacy code. Separates LLM reasoning from deterministic evidence checks and tracks citation validity as code changes. Published evaluations document both citation accuracy and gaps in coverage. MIT.
• greplet — Local hybrid search for code and specification documents, combining vector search and BM25. Returns source locations rather than generated summaries, with workspace indexing and MCP integration for AI coding agents. MIT.
• tierwork — Claude Code / Codex plugin for delegating review tasks and tracking their execution. Makes worker roles, review results, and reuse decisions explicit so completed work can be distinguished from proposed or skipped checks.
• OhMoney-portfolio — Architecture and product-decision record of a 20-agent LLM orchestration system I planned, built, and operated as personal R&D. Covers LangGraph control flow, automated grading, model-routing policies, and staged pipelines with retries and fallbacks.

• B2B SaaS (0→1): Co-founded and led product development for a manufacturing operations platform used across 30+ sites, with offline-first operation and eventual consistency.
• Regulated Healthcare: Led planning and coordination for a 38-person cross-functional CGM platform TF; implementation was handled by an external development partner. The TF achieved 99.9% data integrity and passed validation against MDR/FDA requirements—not regulatory approval or launch.
• Semiconductor / Display: Built and led MES–equipment integration work using SECS/GEM and HSMS, including 4+ years of fab-site work. Designed Core vs Plugin boundaries to reuse platform capabilities across customers.
