💼 What sets me apart

I don't just write the code — I understand the business behind it. Accounting, invoicing, VAT, subscriptions and financial workflows aren't abstractions to me: they're domains I've studied. That makes me a strong fit for fintech, SaaS and business-software teams that need a developer who speaks both languages.
