Glen R.

I’m a senior software developer with 12+ years of experience building complete solutions. My work focuses on real-world integrations, automating business workflows, and connecting systems that normally don’t communicate.

API Integration & Automation
I’ve built end-to-end integrations for platforms such as:
• Authorize.Net – ACH/credit card workflows, recurring billing, subscription engines, customer profiles
• Shopify – GraphQL Admin API integrations, product and inventory sync, fulfillment workflows, reusable integration modules
• Twilio – SMS automation, 10DLC compliance, sender profiles, message scheduling
• DocuSign – embedded signing, routing workflows, signature tracking
• Acumatica – inventory, orders, reporting, custom endpoints

Most of my work centers around solving operational challenges: automating payments, syncing inventory, processing orders, handling messaging flows, and building dashboards or reporting tools that companies rely on day-to-day.

Backend Development (.NET, Python, Azure)
I design and build scalable backend systems including:
• ASP.NET Core Web APIs
• Python services and automation scripts
• Azure Functions (scheduled tasks, event-driven workflows)
• Cosmos DB and SQL-based architectures
• Secure credential storage (Azure Key Vault)
• OAuth2, token refresh processes, micro-service communication

These backends typically support ecommerce integrations, billing systems, data pipelines, or custom business workflows.

Swift iOS Development
I develop native iOS applications in Swift and SwiftUI, focusing on clean UI, strong API communication, and secure data handling. Projects include medical record apps, document scanning workflows, and client-facing booking or scheduling apps.

FileMaker Development (10+ Years)
I have extensive experience building and improving FileMaker systems, including:
• Custom API modules (Shopify, Authorize.Net, Twilio, Google, Microsoft, etc.)
• Complex multi-step workflows and automation
• Dashboards and reporting systems
• Web viewer integrations with JavaScript
• Modernizing legacy FileMaker solutions for performance and maintainability

Background & Approach
My military background built my discipline, attention to detail, and reliability. I take ownership of projects, communicate clearly, and design systems that are stable, maintainable, and practical for real business use.
