Multi-tenant Architecture
Design Firestore and PostgreSQL schemas that cleanly separate tenant data, roles, and permissions from day one.

Mohammad Jamshaid
Flutter & Full-Stack Developer · 3+ years · 40+ shipped apps · 8 countries
I build full-stack Flutter products — from Firestore-powered real-time marketplaces to Node.js backends deployed on Linux VPS. I've shipped 40+ apps for clients in Ecuador, Canada, UK, Egypt, South Africa, and Pakistan, handling everything from architecture and UI to backend APIs, payment integration, and App Store release. If you need it built properly and shipped, that's what I do.
SaaS Development
I build SaaS products that scale
From architecture to deployment — I design and develop multi-tenant SaaS platforms with real users, real payments, and real infrastructure.
Subscription & Payment Systems
Integrated PayFast, PayPhone, Stripe, and in-app purchase flows. Webhooks, ITN handling, and failed payment recovery included.
Admin Panels & Dashboards
Every SaaS needs an ops layer. I build Flutter Web or Next.js admin panels with user management, analytics, and config controls.
Real-time Backends
Node.js APIs and Firebase Cloud Functions that handle live job queues, push notifications, WebSocket events, and status syncing.
Production Deployment
VPS setup with Nginx, PM2, SSL certificates, environment configs, and monitoring. I don't just build — I ship.
Multi-app Ecosystems
Built 3-app systems where a client app, provider app, and admin panel all share one backend. Role-based access, shared Firestore collections, and atomic transactions.

I'm a Flutter and full-stack developer with 3+ years of freelance delivery and 40+ shipped applications — for clients in Ecuador, Canada, UK, Egypt, South Africa, and Pakistan.
I started freelancing in the second year of my BS Software Engineering degree at Islamia University of Bahawalpur, progressing from Android/Java to Flutter, then expanding into Node.js, TypeScript, and production backend systems deployed on Linux VPS.
My work spans two-sided marketplaces, on-demand platforms, SaaS products with subscription billing, scraper-based automation tools, real-time Firebase ecosystems, and full-stack systems with Nginx-hosted backends. I handle the entire lifecycle: architecture decisions, Flutter UI, backend APIs, payment gateway integration, and App Store submission.
I care about code that holds up in production — clean architecture, proper state management, well-structured Firestore schemas, and backends that don't go down.
Education
BS Software Engineering
Islamia University of Bahawalpur (IUB)
2021 – 2025
Started freelancing in 2nd year. Graduated with 40+ delivered commercial projects alongside the degree.
Experience
My development journey
From Java console tasks in 2021 to Flutter full-stack in 2025 — a deliberate four-year progression built through real client work.
2024–Present
Flutter Full-Stack Developer — SaaS & Product Work
Operating as a Flutter full-stack developer under Jaminnova Tech Studio. Delivered large-scale products including ServiceX (3-app service marketplace for Ecuador), Spin Laundry (full-stack Flutter + Node.js), Vroomly (P2P rental marketplace), CampSight (scraper + FCM alerts), DriveMond (multi-country ride-hailing), and Syf Plus (live streaming platform). 40+ projects across 8 countries.
2024 (Mid–Late)
Added Full-Stack Backend — Node.js & TypeScript
Expanded into backend development with Node.js, TypeScript, Prisma, MongoDB, and PostgreSQL. Deployed production APIs on VPS with Nginx and PM2. Integrated payment gateways (PayFast, PayPhone), built Cloud Functions, and architected complete backend systems alongside Flutter frontends.
2024 (Early)
Fully Switched to Flutter
Dropped Android Java and JavaFX from active delivery. Flutter became my primary and sole mobile framework. Completed BS Software Engineering at IUB in 2025.
2023 (Late)
First Flutter Client Projects
Started delivering real Flutter projects for clients. Built multi-screen apps, Firebase integrations, and REST API-connected mobile products.
2023 (Mid)
Started Learning Flutter
Began adding Flutter to my skill set while continuing Android and Java desktop delivery. Explored state management (GetX, Provider) and cross-platform mobile architecture.
2023 (Early)
Added Java Desktop Software
Expanded into JavaFX desktop application development alongside Android work. Built POS systems, business management tools, and desktop software for clients.
2022 (Mid)
Moved into Android Development
Started building Android apps with Java and XML UI. Took on Android freelance work and began growing my client base on Fiverr and Upwork under Jaminnova.
2022 (Early)
First Paid Work — Java Console Projects
Landed first freelance tasks in Java OOP and console-based applications. Built small paid projects for clients while still in Year 2 of my degree.
2021
Started Degree — Java Foundations
Began BS Software Engineering at Islamia University of Bahawalpur. Learned Java fundamentals, OOP concepts, data structures, and console-based problem solving.
Reviews
What clients say.
Jamshaid delivered exactly what I needed — a reliable scraper that notifies me the moment a campsite opens. He understood the problem immediately, handled edge cases I hadn't even thought of, and deployed everything cleanly. Will hire again without hesitation.
