Hi, I'm Jay and I operate [LogicaHaus](https://www.logica.haus/), a one-man development agency. With 10+ years in software development and a previous career in accounting and business management, I bring both technical expertise and business acumen to your project.
**What sets me apart:**
Unlike many developers who focus solely on code, I understand the business side of things too. This means I can help you make better decisions about features, budget allocation, and implementation strategies that align with your business goals. My finance and tech careers have both spanned many industries and I know how to dig deep and ask the right questions.
