Full Stack Developer - for fast, scalable Websites & Web App

Cover image for I rebuilt my developer portfolio

I rebuilt my developer portfolio to attract better clients… not just show projects. I’ve been working on improving my portfolio with one goal: Make it clear for business owners what I can actually solve — not just what I’ve built. So I focused on: Clear service positioning (not just “I do everything”) Showing real use-cases (dashboards, SaaS, business websites) Simple user flow (so clients don’t get confused) Still, I know there’s always room to improve. I’d really appreciate honest feedback — especially from founders, agencies, or anyone who hires developers. What would you change? What feels confusing? What’s missing? Here’s the link: https://rittiksadhukhan.com/
