Software Engineer (Contract)
@ Notary Dash
(Mar 2026 - Current)
-
Led the ground-up V2 rewrite of a multi-tenant notary/signing SaaS (82 Eloquent models, 1,600+ PHP classes) from a legacy 2017 codebase to Laravel 13 / PHP 8.5, running both systems against a shared database throughout the cutover.
-
Drove the frontend migration from Vue 2 to Vue 3 + Inertia v3 + Tailwind v4 across 149 components, holding pixel parity with the legacy UI as an explicit release gate.
-
Eliminated a 900-entry PHPStan baseline to zero, raising the codebase to Larastan level 5 with 100% type coverage and cognitive-complexity gates (class 40 / function 9) enforced on every build with no suppression file.
-
Built and maintain the CI pipeline: the test suite sharded four ways, static analysis, type coverage, formatting, and secret scanning, gated behind required status checks on main.

Software Engineer (Contract)
@ 92 Labs
(Dec 2025 - Current)
-
Built Sidekick from the first commit: a customer-facing display that sits next to KMS Tools point-of-sale tills and shows the live cart over Laravel Reverb, with a presence channel that shows which tills are online in a Filament admin.
-
Designed a versioned, Sanctum-guarded ingest API that feeds per-location stock and pricing into a Lunar e-commerce storefront through batched queue jobs on Horizon.
-
Built store locations, per-location inventory, queued CSV product imports, and display pricing across Club, Industrial, and MAP price tiers.
-
Upgraded both apps to Laravel 13 and Inertia v3, and moved the storefront from Lunar 1.x to the 2.0 alpha.
-
Raised Sidekick to 94.5% test coverage and set up CI on both projects with coverage gates, type coverage, PHPStan level 9, and automatic formatting.
-
Tracked down a race condition that left cleared transactions on the till screen, wrote up the cause, and fixed it with a cache guard.
