Experience

Independent Software Engineer

Self-employed

02/2024 — Present· Rosemount, MN
  • Contracted directly with a service business to deliver a production booking platform end-to-end — Square payments, server-authoritative pricing, and time-slot holds — now processing live customer transactions.
  • Sole engineer for two independent clients over 1 year — owned requirements, architecture, contracts, deployment, and ongoing operations while facilitating design and weekly collaboration.
  • Built an AI agent platform with hybrid retrieval (graph + vector + keyword), a 14+ tool ecosystem with structured schemas, and a deterministic enforcement layer validating agent behavior against architectural constraints.
  • Operated a production server cluster managing ~50 containerized services with NetBird WireGuard mesh networking, resolved 200+ critical CVEs, and implemented dual-repository backups with automated restores.

Software Engineer II

Dell Technologies (Fortune 500 enterprise technology, 160K+ employees)

05/2019 — 02/2024· Round Rock, TX / Remote
  • Managed Microsoft Teams licensing and application policies for 100,000+ users via PowerShell automation across multiple acquisitions, ensuring consistent access controls and service entitlements.
  • Provisioned conferencing for 50,000+ and enterprise voice for 30,000+ users across Teams and Zoom, managing complex service orchestration with overlapping entitlements.
  • Engineered Active Directory scanning and auto-sync automation so acquired telephony inventory integrated without manual intervention, reducing provisioning time by 25%.
  • Developed a Python-based meeting room implementation tracker, ingesting database inventory and Smartsheet vendor data to automate Jira status updates for 100+ meeting rooms globally, reducing manual tracking by 15 hours per week.
  • Built executive Power BI dashboards with automated data pipelines for daily tracking of global telephony rollout, replacing weekly manual status reports and cutting reporting cycle from 3 days to daily refresh.
  • Led secrets management standardization for a 40-person team as Secure Development Champion — replacing plaintext secrets with encryption certificates and vault API integration.
  • Owned Microsoft Teams app governance for 50+ teams, reviewing an initial ~400 apps for security compliance and establishing a controlled approval workflow aligned with corporate and cyber standards.
  • Designed and deployed a Microsoft Teams domain-whitelisting system using Azure Automation, PowerShell, and Logic Apps to control external communications across the organization during a security response.
  • Contributed full-stack features (UI components, APIs, and PostgreSQL schema) for scheduling and approval workflows on an internal communications platform.
  • Drove infrastructure CVE remediation across team servers — patching automation dependencies, coordinating MongoDB upgrades, and restricting SSH access — owning the application-level changes Cyber Security required.

Projects

Payment and Booking System

Next.js, React, TypeScript, PostgreSQL, Square Payments, Tailwind CSS, Nix

  • Delivered a production system accepting customer bookings with Square Web Payments and server-side validation across 15+ error mappings.
  • Built a checkout flow with server-authoritative pricing — all amounts recomputed from the database at payment time, rejecting client-supplied values.
  • Implemented a time-slot hold system that prevents double-booking by merging active holds with confirmed bookings against available capacity.
  • Led infrastructure migration from single VPS to server cluster with NetBird WireGuard mesh networking and Nix-based CI/CD pipeline with Trivy scanning.

Service Cluster

Docker, NetBird, MinIO, pgBackRest, Traefik, Wazuh, Nix

  • Architected and operated a server cluster with NetBird WireGuard mesh networking, managing ~50 containerized services across production workloads including source control, identity, search, and monitoring.
  • Designed backup and disaster recovery strategy with pgBackRest dual-repository architecture, TDE-aware WAL archiving, and automated restore pipeline.
  • Resolved 200+ critical CVEs across deployed services, VPS servers, and development systems — maintaining a clean security posture across the entire infrastructure.
  • Deployed a security stack with Transparent Data Encryption, field-level AES-256-GCM encryption via KMS, mutual TLS with PKI-managed certificates, and PostgreSQL Row-Level Security policies.

LLM Inference and Agent Platform

vLLM, LiteLLM, Ollama, TypeScript, Embeddings

  • Designed server hardware requirements and deployed AI inference infrastructure serving a large language model via vLLM with LiteLLM API proxy.
  • Built a deterministic enforcement layer to validate agent behavior against architectural constraints — using static policy checks, session log replay, and CI linting.
  • Architected a hybrid retrieval system combining graph traversal over linked notes with vector embedding search and keyword fallback.
  • Created a tool ecosystem of 14+ capabilities — from vault search and web browsing to code intelligence and system automation — each with structured schemas and deterministic error handling.

Realty Engagement Platform

TypeScript, Next.js, React Native, Express, PostgreSQL, Firebase, Apple APNs

  • Built a complete platform around a thin mobile client — Express REST API, Next.js admin dashboard, and authentication service — with a single PostgreSQL database serving all layers.
  • Designed a notification-driven data freshness system using short-term and long-term memory with selective cache invalidation, keeping the app current without constant polling or excessive API/battery cost.
  • Enforced per-user data isolation with PostgreSQL Row-Level Security and transaction-scoped identity injection via middleware, ensuring users can only retrieve their own records at the database level.
  • Shipped a production React Native app to iOS and Android, including the native configuration and integration work required for store release.
