You will get clean, reliable database design & query optimization
Project details
Databases are the foundation everything else depends on — get the design wrong and every feature built on top of it inherits the problem. With 7+ years of professional experience across PostgreSQL, SQL Server, and Oracle, I design schemas properly normalized from the start, write queries that scale, and explain the reasoning behind each decision so you're not left with a black box. Whether you're starting fresh or untangling a slow, poorly structured existing database, I focus on getting the fundamentals right the first time.

About Derek
Web & Software Developer
Kansas City, United States - 3:19 am 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
