Lead development of the iVMI connected inventory platform, applying LLM-powered automation while modernizing cloud applications, edge-device software, billing services, customer workflows, and production infrastructure.

•Developed Python and LLM automation for log analysis, support triage, test generation, and technical documentation, reducing repetitive engineering work while preserving human review.

•Led an 8-member engineering and product team, establishing architecture standards, sprint priorities, code reviews, release controls, and production-readiness requirements.

•Re-architected the Raspberry Pi edge device software using ElectronJS to interface with load-cell scales via serial

(XBee + USB); replaced fragile tkinter GUI with a robust watchdog-based system that auto-restarts within 5 s of failure.

•Built scale registration, customer billing, and access control logic using Stripe and Firebase; system enforces 30-day trials, disables access upon payment failure, and tracks per-seat, per-scale subscriptions + hardware financing.

•Overhauled inventory, device, authentication, subscription, and billing services using Node.js, Nest.js, and GraphQL, keeping frequently accessed API responses below 50 ms.

•Integrated Claude Code into implementation, debugging, refactoring, and test development, reducing routine development time by approximately 35% with mandatory review for sensitive changes.

•Built responsive React and TypeScript dashboards and React Native workflows, achieving critical page loads under 1s and simplifying inventory and device administration.

•Redesigned Firebase and PostgreSQL data models, improved query performance by more than 60%, and automated releases through CI/CD, AWS, Lambda, and Kubernetes with rollback and recovery controls. Senior Software Engineer
