Company: Map's Edge Creative Engineered a custom PHP e-commerce platform from inception, incorporating a plugin system with per-plugin licensing and a multi-state sales tax engine. Identified and remediated a critical remote code execution vulnerability within the admin file upload system, subsequently spearheading a comprehensive security review across licensing checks, session handling, and all upload endpoints. Developing EdgeCart, a commercial iteration of the platform, featuring a plugin marketplace, a robust licensing and signing system, and a public- facing sales site. Enhanced two open-source projects, KDE's kfind and the AutoKey automation tool, by contributing improvements to their Qt interfaces, including sortable and resizable columns, dark theme support, search functionality, and inline editing, all currently under maintainer review.

Company: Ruco Products, Inc. Managed server migrations and upgrades, including hands-on training for staff so they could maintain and operate the systems independently going forward, rather than relying on outside support after the transition. Modernized legacy Classic ASP applications by refactoring them onto a SQL Server backend, bringing the codebase up to current standards to improve long-term maintainability and reduce technical debt. Optimized front-end interfaces across the platform, achieving up to a 75% increase in load and interaction speed. Built AI-driven features for their e-commerce platform, and designed the underlying database structure to support them cleanly rather than bolting functionality onto the existing schema. This included a custom migration tool that moves data from SQL Server to MySQL with real-time progress tracking, automatic type mapping between the two database engines, batched inserts for performance, and row-count validation after each table so migration accuracy could be confirmed rather than assumed. Also refined several user-facing workflows to reduce friction and improve clarity for end users. Used Claude AI throughout the engagement to parse and refactor complex, undocumented legacy logic, which meaningfully cut down development time on tasks that would otherwise have required slow manual reverse-engineering.
