Hello! I’m Daniel, a Full Stack Software Engineer.
With 3+ years of freelance experience, I've delivered 40+ projects for international clients.
As a Computer Science student, I specialize in taking ideas from concept to a deployed product. My expertise lies in building scalable backend architectures with Node.js, TypeScript, and AWS, alongside crafting high-performance interfaces using Next.js and React.
Whether you need a robust RESTful API, microservices with Docker, database optimization, or a custom SaaS platform, I deliver clean, maintainable code.
Let's build something great!

Veelgestelde vragen
Can I easily add this calculator to my website (WordPress, Wix, Shopify)?
Yes! I will provide you with the clean, optimized source code or an easy-to-embed iframe snippet that you can paste directly into your website builder. If you need help, I offer an extra service to set it up for you.
Do I need to provide the mathematical formulas?
Yes. To ensure 100% accuracy, I need you to provide an Excel sheet (.xlsx) with the working formulas, or a detailed document explaining the mathematical logic step-by-step.
Will the calculator work and look good on mobile phones?
Absolutely. Every web calculator I build is fully responsive by default. It will look perfect and function smoothly on desktops, tablets, and smartphones.
Can I use this calculator to collect emails from my visitors?
Yes! Lead generation is one of the best uses for a web calculator. I can integrate a form that requires users to enter their name and email before seeing their results (available via Gig Extras).
