Gig Summary
About this gig
Need a SaaS platform, CRM, or internal system that fits how your business actually works, instead of forcing your team into off-the-shelf software?
I'm a software engineer specializing in SaaS applications with Laravel.
This gig is rated 4.8 stars by 25+ clients, and I build secure, scalable systems from MVP to full multi-tenant platform.
What I can build:
- Multi-tenant SaaS with subscriptions, billing and trials
- Custom CRM and ERP: sales, inventory, HR, invoicing, reporting
- Admin panels, dashboards and customer/vendor portals
- REST APIs ready for a Flutter mobile app
- Role-based access for admin, staff and clients
- Integrations: Stripe, WhatsApp/Twilio, maps, email
Stack: Laravel, PHP, MySQL/PostgreSQL, REST API, Tailwind/Bootstrap, Git, VPS deployment
Why me: clean documented code, staging preview before launch, source code included, and clear updates at every milestone.
Please message me before ordering with your feature list. I'll review it for free, suggest the smartest MVP, and give you an exact price and timeline.

This is not the very first time that we work together, and in each challenge we all get what we need and even better. I would keep recommending Sadia for his hard work and also understanding. Though this took a while, but at the end it worth it.
