Product & Platform Architecture

• Architected and built a CPA operations suite: a monorepo of 6 independently-deployed Next.js apps (SSO identity portal, double-entry bookkeeping, tax, RAG knowledge assistant, firm-wide AI agent) sharing 10 versioned packages, with contract-first typed APIs (oRPC + Zod) and PostgreSQL/pgvector — breaking API changes fail consumers' builds.
• Built a double-entry bookkeeping platform with AI-powered statement import (OCR + LLM PDF extraction), balance sheet / P&L reporting, reconciliation, and audit-safe journal-entry accounting for live client financials.
• Built an internal project command center with a built-in MCP server (20+ tools) so AI agents operate projects and tasks through the same typed API and per-user auth as human users.
• Shipped a cross-platform community product — Next.js web + Expo React Native mobile sharing one end-to-end-typed API and a single design-token source — with passwordless magic-link auth and TestFlight distribution.

Deployment & Infrastructure

• Designed the company's complete CI/CD and delivery architecture: GitHub Actions with affected-app build matrices, container images to GHCR, and a custom pull-based (GitOps-style) deploy agent — automatic staging deploys on green builds, human-gated production promotion via tags, container-health gating, and tag-based rollback.
• Operate the full stack across Azure and on-prem Linux servers: Docker Compose services, reverse proxies, SSH-tunneled database operations, backup/restore procedures, and zero-regression schema/data migrations against production financial data.

AI Systems

• Deep AI integration across the portfolio: Anthropic-powered in-app agents with typed tool access, retrieval with vector embeddings, MCP servers for agent interoperability, and automated document-understanding pipelines (statement parsing, classification, extraction).

AI Systems & Infrastructure

• Architected Context Engine, an AI-powered developer productivity platform integrating Jira, GitLab, and semantic search via vector embeddings; built auth, permissions, and a TypeScript API client — shipped to production in 3 weeks, winning the company hackathon.
• Built an MCP (Model Context Protocol) server enabling Claude Code integration with internal systems, bringing AI-assisted workflows to the engineering org.
• Developed automated ticket classification and Jira ticket creation from natural-language chat, streamlining sprint planning and root-cause analysis.
• Created Merge Reporter, an AI-powered GitLab→Jira bridge that eliminated manual status reporting entirely — and runs for a few dollars a month.
• Designed the Web Dev Mastery training program with AI-graded exercises, scaling mentorship across the Web Chapter.

Technical Strategy & Architecture

• Defined the platform-consolidation strategy and led a 5-engineer team through it — a codebase-wide refactor delivered across 4 sprints, whose patterns became the standard for all internal tool migrations.
• Designed an authentication framework (@youversion/next-auth) that eliminated token-storage vulnerabilities; adopted as the org-wide standard.
• Identified architectural debt in Bible.com blocking future features; led the refactor enabling 330M-user reach across 10 new languages — “the biggest language launch for BDC in a long time.”
• Architected a type-safe configuration system in active use across the codebase.

Cross-Functional Leadership & Delivery

• Architected and delivered the Story Builder platform from concept to production in 30 days — pushed back on a flawed proposed solution, built a 2-day proof-of-concept to align teams, and shipped a platform now serving 20+ enterprise partners.
• Bridged the Internal Tools and Strategic Missions teams during the CMS Rebuild, owning App Preview, Search, and Foundation components — delivering 80%+ of the Optiframe frontend while learning .NET for seamless cross-stack integration.
• Shaped the Internal Tools roadmap — proposed a Support Portal repurposing strategy adopted by the architecture team.

Force Multiplication & Mentorship

• Resolved a months-long CI/CD blocker affecting all review apps, unblocking developer velocity across 6+ teams.
• Built unsolicited internal tools (Roles & Permissions UI, Merge Reporter, Context Engine) saving hundreds of engineering hours annually — used org-wide.
• Mentored engineers across levels while carrying a full delivery load alongside architecture ownership and cross-team coordination.

• Led technical interviews for team expansion; established code standards and architectural patterns for a greenfield Angular SPA with a custom Node.js/SQL backend.
• Built task management, authentication, dynamic form rendering/validation, account management, and construction workflow systems serving 20+ project workflows.

• Architected a cross-platform medical administrative system with SignalR real-time communications; implemented a full SQL database with .NET Core and Entity Framework.
• Created GitLab CI/CD pipelines with Azure deployments, establishing DevOps practices for automated builds and testing.

• Developed OCR and billing software frontend for medical claims processing, automating manual workflows while maintaining HIPAA compliance.
• Migrated a legacy VB.NET codebase to Java Spring Boot with a SQL Server/PostgreSQL backend, modernizing critical business systems.
