Back to original languageAbout Niclas
I help companies and self-employed individuals automate processes and quickly implement web apps.
I built a complete digital infrastructure myself – including:
- SaaS accounting software (Orvello)
- Online shop with payment processing
- Invoicing and backend systems
This means: I don't just think in code, but in solutions.
Typical projects I can help with:
- Automation of business processes (e.g., invoices, emails, data)
- Development of web apps (Next.js, APIs, databases)
- Bringing MVPs from idea to live quickly
- Integration of existing systems
I work fast, pragmatically, and with a focus on results.
If you have a specific problem, I can usually tell you how to solve it efficiently in a short time.
