You will get NPM package upgrade & fixes
Project details
Package updates are often put off because "it might break something" — I make that process safe. With 7+ years of professional React/.NET experience and a background as a certified technical trainer, I update incrementally, test as I go, and document exactly what changed and why — so you're never left guessing what broke or how it got fixed.

About Derek
Web & Software Developer
Kansas City, United States - 3:23 pm local time
I specialize in small, fixed-scope work — bug fixes, feature updates, package upgrades, and targeted improvements to existing codebases. I'm comfortable dropping into unfamiliar code, tracing down root causes, and making surgical changes without introducing regressions or unnecessary complexity.
Before development, I spent 3 years as a certified technical trainer (CompTIA CTT+), teaching full-stack development to 100+ students a year — so I communicate clearly, document what I change, and don't leave clients guessing about what happened and why.
Core Skills:
C# / .NET / .NET Core
React, TypeScript, JavaScript (ES6+)
PostgreSQL, SQL Server (T-SQL)
RESTful API development & integration
HTML5, CSS3, responsive design
Git / GitHub
Docker
