Introduction

I'm a full stack developer with 10+ years of experience shipping software, from payment platforms and customer portals to 3D marketing apps and hybrid mobile products.

Away from work I'm a game jam regular, always tinkering on a side project (and playing too much Age of Empires II: DE).

Work

Sonar SoftwareSoftware Engineer → Senior Software Engineer · Full-timeJan 2021 – PresentRemote

Full-stack and mobile engineer spanning three products over 5 years: sole developer of the field-technician mobile apps, payments/billing owner on the core web platform, and feature developer on the customer self-service portal.

Mobile: Field Tech (Flutter → React Native)

  • Sole developer of Sonar's offline-first field-technician mobile app in Flutter (886 commits, versions 0.13→0.16), used by ISP installers to manage jobs, tickets, inventory, and provisioning
  • Architected an offline-first sync engine (mutation queue with retry/backoff, connectivity detection, and a Drift/SQLite local database with a multi-version migration path), enabling technicians to work without connectivity
  • Led a ground-up Flutter rewrite to Riverpod state management and a repository pattern, consolidating three data-mutation patterns into one documented standard
  • Rebuilt the app from the ground up in modern React Native (RN 0.79, TypeScript, React Navigation 7, Apollo GraphQL, Redux Toolkit) with a redesigned UI and full light/dark theming across ~17 screens (2025–2026)
  • Currently building white-label sales and customer-portal app variants for ISP clients on the same React Native foundation
  • Shipped high-value field features: credit-card scanning for on-site payments, handwritten-signature contracts, iOS Live Activities for job tracking, global search, and a technician dashboard
  • Integrated Calix SMx provisioning and Auth0 SSO with MFA; built the mobile CI/CD pipeline (Azure Pipelines + GitHub Actions, Fastlane, ConfigCat flags) and a Patrol end-to-end test suite with full internationalization

Core Platform: Payments & Billing

  • Owned the SonarPay payments domain end to end: disbursements, disputes, AVS/CVV/3DS verification, and void/refund/reverse-payment workflows across multiple processors (Payrix, ProPay)
  • Delivered Flexible / 30-Day Billing: configurable service-period offsets, bill-day vs. invoice-day logic, proration, and delinquency calculations, rolled out behind feature flags
  • Drove a frontend de-globalization refactor converting 35+ global services to explicit imports/singletons, resolving circular-dependency and webpack memory issues and modernizing the unit-test suite
  • Built a code-generation pipeline for type-safe enums (with translation integration) reused across the entire codebase, plus the mobile-app login backend (Auth0, FCM push notifications)
  • Rebuilt the account overview into a permission-aware, user-customizable dashboard, and shipped RADIUS session tooling, SAML/Active Directory auth, and Print-to-Mail invoice batching

Customer Portal

  • Overhauled the subscriber payment experience: billing summaries, auto-pay UX, multi-currency support, and Stripe integration updates
  • Implemented NACHA compliance and Canadian bank-routing support, plus credit-card-processor gating and multi-language (French) localization
