Resume

One of two engineers building a payment processing platform for automotive dealerships. Company ranked #120 on the Inc 5000 list, with the platform helping dealers save over $68 million. Led system design and architecture planning across 6 interconnected core services. Picked up PHP and Laravel on the job — had never written a line of PHP before starting.

Electron Desktop POS App

Electron, React, TypeScript, Vite, Material-UI, TanStack Query, Zustand

• Led migration from Create React App to Vite + TypeScript, modernizing the build toolchain for a production POS application
• Consolidated 6 siloed integration components (~4,460 lines of duplicated code) into a single unified transaction flow supporting CDK, Dealertrack, and Dominion DMS systems
• Built multi-payment processing (card, cash, check), Z-Reports with PDF generation, and a one-click debug report feature for support
• Resolved macOS ARM64 code signing for cross-platform distribution (Windows MSI/NSIS + macOS DMG)

Laravel Payment API Built from scratch

Laravel 12, PHP 8.2, MySQL, Valor PayTech API, SendGrid

• Designed and built a new Laravel backend from the ground up to replace legacy vanilla PHP endpoints, with multi-database architecture, repository pattern, and standardized API responses
• Implemented full transaction processing pipeline with Valor PayTech API integration, server-side receipt generation, and DMS payment settling across three providers

Legacy PHP API Modernization

Vanilla PHP, MySQL, Session Auth

• Inherited and refactored a legacy vanilla PHP API — introduced security middleware, session-based auth, rate limiting, and endpoint versioning
• Documented the full Laravel migration path, creating the blueprint used to build the new backend

Internal Admin Portal

React, TypeScript, shadcn/ui, Tailwind, Laravel, Google OAuth

• Built and maintained the admin portal (500+ commits) for managing stores, terminals, users, and transactions across the fleet
• Designed merchant onboarding wizard, launch management system with Google Calendar integration, and bulk CSV import for terminals/users
• Optimized API response times from 8s to 450ms (17x improvement) on critical endpoints

DMS Integration Microservice

Laravel, Fortellis API, OpenTrack SOAP, Dominion SecureVUE

• Built microservice handling real-time communication with CDK, Dealertrack, and Dominion — the three major automotive DMS providers
• Implemented structured debug logging with correlation IDs for tracing requests across the distributed system
