Hi π, I'm Muhammad Harris Baig
I design backend-heavy SaaS platforms that power real operational workflows β focusing on system architecture, multi-tenant design, and business-critical API engineering.
Operating across π¬π§ UK β’ πΊπΈ USA β’ π Global clients
Open to Backend Engineering β’ SaaS Architecture β’ System Design Roles
- π Build backend-driven SaaS platforms used in real operational workflows
- π§ Focus on scalable system design, distributed architecture, and backend reliability
- ποΈ Experience building multi-tenant systems with strict role-based access control
- βοΈ Design and deploy API-first cloud applications
- π± Build full-stack products integrating backend + mobile ecosystems
π I focus on systems that behave like real software infrastructure, not demos or prototypes.
- Designed multi-tenant SaaS architectures with strict data isolation models
- Built event-driven backend systems for workflow-based applications
- Engineered end-to-end business systems (booking, procurement, dispatch, commerce)
- Designed normalized relational databases for scalable SaaS platforms
- Built API-first backend systems supporting web and mobile clients
π Strong focus on backend architecture, system reliability, and structured business logic design
A private hire dispatch system designed for fleet operators and real-world operational use.
Core System
- Multi-company operational architecture (multi-tenant structure)
- Real-time booking lifecycle engine
- Driver and vehicle allocation system
- Admin + operator control dashboards
- Payment-ready dispatch pipeline
Business Flow Booking β Pricing β Payment β Dispatch β Completion
Tech Stack Next.js β’ Node.js β’ Prisma β’ PostgreSQL β’ Stripe β’ REST APIs
I build mobile applications that are fully integrated into backend-driven systems:
- π² Cross-platform development (React Native / Flutter)
- π Deep backend integration with real-time APIs
- π§ Intelligent feature systems (AI / detection-based logic)
- π Converting academic FYPs into production-ready systems
π Mobile is treated as a first-class product layer inside full systems, not an isolated skill.
