Summary

Applied AI / full-stack engineer with 5 years shipping production software. At RadiusXR I own the internal platform for a Class 1A medical-device company: company-wide LLM gateway (50-100 jobs/day), agent tooling, manufacturing MES-lite, UAT release gates, returns/FedEx logistics, and fleet release for ~4,000 devices. Cloud paths I have shipped: AWS S3 object storage, Render compute + managed Postgres, Cloudflare Workers edge proxies, async job queues/workers, OAuth multi-app access, Google Workspace APIs, Salesforce integrations. Full-stack across Node.js, Python, Google Apps Script, and Swift. Targeting Applied AI, AI platform, and Forward Deployed Engineer (FDE) roles that own agents, customer integrations, evals, and production reliability end to end.

Experience
RadiusXR- XR & low-vision medical device company, Pleasanton, CA
Senior Technical Product Specialist Mar 2025 - Present
  • Own Radius's internal software platform (9+ tools, Apps Script / Node / Puppeteer) used daily by ~25 people across manufacturing (5-8 floor), QA (~9), support, CS, and leadership: production, UAT, returns, fleet release, analytics, LLM gateway.
  • Designed claude-queue, a company-wide LLM gateway (write-up): durable async job queue (submit/poll), self-hosted Node worker, model routing, streaming tool-use progress, OAuth-scoped multi-app access; 50-100 prompts/day; replaced scattered direct API calls.
  • Built UAT Tracker for ~178 cases across 5 product surfaces: release-scoped coverage, Gemini-drafted Jira bugs, management progress views, and AI-assisted stakeholder sign-off that gates fleet releases.
  • Shipped Production System for floor kitting/PTA/NCR with versioned DHR PDFs: full-system provision under 5 minutes (from 30-45 min manual assembly); multi-user row locking after concurrent-write failures.
  • Built Knox MDM release framework for ~4,000 tablets (tiered rollouts, legacy groups, OAuth rotation): rollout failure ~30% to under 5%.
  • Built Returns + logistics stack (Salesforce RMAs, FedEx labels/batch ship, scheduled tracking sync, refurb-to-stock) and an Operations Dashboard (Mixpanel trials/utilization + on-demand AI leadership reports).
Technical Product Specialist Jul 2024 - Mar 2025
  • Automated Onboarding Registration (Salesforce + parameterized URLs): support calls down 80%; unlocked a major distribution partnership.
  • Built Inventory & QMS tracking for FDA Class 1A devices: 1,000+ unit shipments at ~10× prior throughput; Salesforce + FedEx automation.
  • Delivered early DHR / production automation path that removed hand-assembled PDF bottlenecks and set up MDSAP/FDA-ready device history generation.
Vagaro- Dublin, CA
Software Support Engineer Dec 2022 - Jun 2023
  • Built Python automation for support workflows that raised weekly ticket resolution capacity 30%; diagnosed a critical intermittent payment bug with engineering.
  • Optimized hot-path SQL for appointment scheduling - average query time down 40%.
Workday- Pleasanton, CA
Software Engineer Jul 2019 - Dec 2021
  • Automated supplier-invoice approval workflows with messaging - pending-invoice duration down 25%; increased on-time payments.
  • Built automation test suite for proprietary Xpresso language - pre-production bugs down 15%; designed schemas and optimized queries for Financial Supplier Accounts.
Personal Projects

Built on my own time, separate from RadiusXR work. Work systems (claude-queue, production, UAT, returns, fleet) are under Experience.

Murmur - On-device STT (local-first): Watch/iPhone capture, LAN/Multipeer/CloudKit sync fallbacks, Mac Parakeet TDT on Neural Engine. Privacy-first (no cloud STT). SwiftUI, TCA.
SoundBite - Article-to-audio: Flask/Gunicorn API on Render, managed Postgres, AWS S3 for MP3 + word-timestamp JSON (boto3), async worker (LLM summarize + TTS), iOS share extension. Decoupled media plane from compute.
Dumbell - iOS workout app: AI analysis/builder via Cloudflare Worker edge proxy (API keys off-device, usage KV caps); SwiftData + private CloudKit sync; StoreKit 2, HealthKit.
AI Skills - Open agent skills (Claude Code / Cursor / Grok): tool-scoped workflows, session snapshot handoffs, onboarding from real screen recordings, paginated HTML-to-PDF.
Reticle - macOS menu-bar capture tool: annotation editor, local capture queue/chaining, OCR smart filenames.
