Most teams call me when an app already exists and is not working — a dashboard rendering blank, a design that never became a frontend, a repo whose developer stopped replying. I read what is there, tell you what is salvageable, and finish it. I also build from zero when that is the right call. Five-plus years across SaaS, e-commerce, and AI tools.

Common questions

Are you available for freelance projects right now?
Yes — I'm open to select freelance projects and full-time startup roles. Best way to start is a 15-minute call or an email to jawadmirza606@gmail.com.
What kind of projects do you take on?
Three kinds, most often. Taking over an existing codebase — fixing production bugs, finishing what a previous developer left, or rebuilding an app that is not working. Turning a Figma design into a real React or Next.js frontend. And building SaaS MVPs from zero. Plus Shopify apps (embedded admin apps, not storefront builds) and AI features in existing products.
What is your hourly rate or pricing?
Rates depend on scope and engagement type. I work on both hourly and fixed-price contracts. Book a call and we can discuss what fits your project.
Do you work with US / UK / Canadian clients?
Yes — most of my clients are in the United States, United Kingdom, Canada, and Australia. I'm fully remote and adjust my hours to overlap with your timezone.
