Yes! I'm always open to exciting freelance opportunities. Whether it's a full product or just a specific feature, let's talk about your project.
I follow a structured agile approach: Discovery → Design → Development → Testing → Deploy. I keep clients in the loop at every stage.
It depends on project complexity. A simple landing page takes 1–2 weeks. A full-stack web app typically takes 4–12 weeks.
Absolutely! I collaborate with clients globally and am comfortable working across different time zones via async communication.
Have an idea? Let's turn it into reality. I'm currently available for new projects and collaborations.
