Aug 2021 – May 2026

Application Development Advisor

Cigna Supplemental Health Services (via Magnit Global) · Remote

Lead and core developer on the Oracle APEX applications powering a national supplemental-health-insurance underwriting pipeline, from quoting through contract generation.

  • Lead developer on the quote-entry front end of the underwriting pipeline — used daily by sales, pricing, and underwriting teams — and core developer on the downstream contract-generation tool, across the full tenure.
  • Introduced Git and GitHub to a team with no source control, establishing the branching, code-review, and commit standards adopted across the group, with admin over 29 repositories.
  • Co-designed the team's first CI/CD pipeline and led the Oracle APEX deployment-workflow integration.
  • Designed and built a custom domain-specific language and Python package that compiles PL/SQL objects in correct dependency order across environments — replacing an error-prone manual process — plus a companion VS Code syntax-highlighting extension.
  • Built a Python abstraction layer over the OracleDB environments that let Claude, via Cursor Composer, query enterprise databases through a locally-running credentialed utility — one of the team's first production AI integrations.
  • Authored an OCR-backed ETL pipeline using pandas and pytesseract that migrated inconsistently structured Excel pricing data — including rate tables embedded as images — into Oracle on upload.
  • Mapped dependencies across 15+ applications and hundreds of database objects with graphviz and networkx into architectural reference graphs delivered to leadership.
  • Led a four-developer squad: task delegation, code review, and technical direction.
  • Oracle APEX
  • PL/SQL
  • Oracle Database
  • Python
  • Jenkins
  • GitHub
  • Liquibase
  • pandas

Jul 2020 – Jun 2025

Freelance Systems Engineer

Independent · Remote

Independent contract engineering spanning embedded/IoT devices, data-analysis pipelines, and web systems.

  • Designed and prototyped IoT security devices: embedded firmware in C and Python, custom PCB design, and sensor integration.
  • Built data-analysis and automation deliverables over real-world and scientific datasets — including geospatial work (Python/pandas, netCDF, cartopy mapping, statistical analysis) — alongside web development and systems integration.

Jun 2020 – May 2021

Radar Systems Engineering Intern

Northrop Grumman Mission Systems · Remote

Defense systems engineering on a cleared program (DoD Secret), performed fully remotely.

  • Held an active DoD Secret clearance — obtained April 2020; lapsed 2021, eligible for reinstatement — on a cleared defense systems-engineering role performed fully remotely.
  • Worked within large-scale defense systems-engineering processes, documentation standards, and cross-functional team workflows.

Selected projects

A few of the things I've built — AI-assisted tooling, enterprise data, geospatial systems, and scientific computing.

Jarvis — A Local-First Voice Assistant

The LLM-era successor to Walter: a local-first voice assistant — wake word, voice-activity detection, streaming speech-to-text, a pluggable LLM brain that calls tools over MCP, and a fine-tuned voice — all wrapped around a single security gate. Built AI-assisted, in active development.

  • Python
  • openWakeWord
  • Silero VAD
  • faster-whisper
  • Ollama / Claude
