SaaS & Web App Development

SaaS platforms and web apps built to grow with your business

I design and build multi-tenant SaaS products, dashboards, internal tools and APIs with Laravel, Node.js, Vue and React, from the first database table to production deployment.

How I work

A note from Emad

I've spent more than six years building business software: affiliate tracking platforms, clinic management systems, invoicing SaaS, HR systems, fleet management and multi-module membership platforms. The pattern is always the same. A business process that lives in spreadsheets and people's heads becomes a system that's faster, clearer and easier to grow. You work directly with me, the person designing the database and writing the code.

Sound familiar?

  • You have a product idea and need a working MVP to put in front of users
  • Your team runs the business on spreadsheets that no longer keep up
  • Your existing app is slow, fragile or hard to change
  • You need billing, roles and permissions done properly
  • You need your systems to talk to Shopify, payment gateways or other tools

FAQ

Common questions

Something else on your mind? Ask me directly. I usually reply within 24 hours.

How long does it take to build a SaaS MVP?

A focused MVP with authentication, one core workflow, billing and an admin panel typically takes 6 to 12 weeks. The written scope at the start sets a realistic timeline for your specific product.

Laravel or Node.js: which should I choose?

Both are excellent. Laravel is my usual choice for business SaaS because authentication, queues, scheduling, billing and email come ready. Node.js fits well for JavaScript-only teams and real-time features. I build in both.

Can you take over an existing project?

Yes. I start with a short code review, set up a staging environment and tests around the critical flows, then continue development in your repository.

Do I own the code?

Yes, completely. The repository, hosting, domain and third-party accounts are created in your name, and I'm added as a collaborator.

Can you work with my existing team?

Yes. I've led teams of 4–5 developers and I'm comfortable joining an existing team, reviewing pull requests and coordinating with designers, QA and outsourced developers.

Which time zones do you work with?

I'm in Dhaka (UTC+6) and overlap with the Middle East for most of the day and with Europe in the morning. Work continues while North American clients sleep.
