Hi! I'm Muhammad, a full-stack developer with 6+ years building SaaS products with real product logic: billing, roles, dashboards, CRMs, messaging, APIs, reports, and AI-powered workflows. I build and repair React, Next.js, Node.js, Express, NestJS, MongoDB, PostgreSQL, Supabase, and TypeScript apps that need to hold up in production.
Most developers can build screens. The harder part is building the system behind those screens: the data model, user permissions, payment flow, admin logic, API structure, third-party integrations, AI features, deployment setup, and the edge cases that show up after real users start using the product.
Results That Speak:
- 6+ years of experience
- Top Rated Plus (React | Next.js | Node | AI Integration)
- 5 Star client reviews for speed, reliability & communication
- 6,000+ hours logged | $300k+ earned | 100+ projects delivered
That's where I usually fit in.
I work best on SaaS platforms, AI-powered tools, internal dashboards, CRMs, marketplaces, booking systems, real-time apps, and web/mobile products where the application is more than a basic frontend.
The kind of problems I handle:
- Turning a rough SaaS idea into a working MVP with frontend, backend, database, auth, payments, and deployment
- Cleaning up React or Next.js apps that became hard to maintain
- Fixing slow dashboards, broken APIs, unstable database queries, Stripe issues, auth bugs, and deployment failures
- Building admin panels, user roles, subscription flows, notifications, messaging, reporting, and workflow automation
- Integrating Stripe, Stripe Connect, Twilio, Google Maps, Firebase, OAuth, JWT, webhooks, and custom APIs
- Adding real AI features (OpenAI, Claude, Gemini, RAG pipelines, MCP, agents) where they make the product more useful, not just because "AI" sounds good
Recent product work includes:
- Averi AI - AI marketing SaaS built with Next.js, PostgreSQL, and AI integration. Led engineering and helped raise $5M seed funding.
- Autobunny - platform for car dealerships that reduced manual dealer tasks by 60%.
- Westepforward - AI-based EdTech exam prep platform with real-time analytics and admin tools.
- Chlk - Fabric.js / Konva.js canvas app built for NFL coaches with rich play-design features that cut design time by 50%.
- Traceo - browser-based bug capture tool for dev and QA teams (Co-Founder & CEO). Built on Next.js, NestJS, and Supabase with a Chrome extension and AI-assisted reporting.
Tech I use Daily:
- Frontend: React.js, Next.js, Tailwind, Fabric.js, HTML/CSS
- Backend: Node.js, NestJS, Express, GraphQL, REST
- Databases: MongoDB, PostgreSQL, Supabase, DynamoDB
- Mobile/Desktop: React Native, Electron.js
- Cloud & DevOps: Vercel, AWS, Heroku, Hostinger
- AI Tools: OpenAI (GPT-4), VAPI, Claude, Together.ai, LangChain, n8n
When I start on a project, I don't jump straight into code. I first look at the product goal, user roles, database structure, API flow, payment logic, integrations, and deployment plan. Bad architecture early usually turns into expensive cleanup later, so I prefer building it correctly from the start.
I'm a strong fit if you need a developer who can take ownership of a real product, make technical decisions, and ship AI SaaS features that work beyond the demo stage.
Send me your app details, current stack, and what needs to be built or fixed. I'll respond with a practical technical plan.

Hi,
Modern products need more than just code. They need speed, scalability, great user experience, and automation that actually moves the business forward.
I've helped 30+ startups build and launch AI-powered SaaS platforms; from zero to production-ready; across 54 projects and 6,400+ hours of real-world delivery, With 7+ years of full-stack experience in React, Next.js, React Native, Node.js, and OpenAI integrations, I specialize in products that launch fast, scale reliably, and drive real business results; not just clean code.
What I work on most:
- AI-powered SaaS platforms: GPT workflows, intelligent chatbots, content automation, semantic search, and recommendation systems that used to take a whole data team to build.
- Full-stack web products: React, Vue Next.js, Node.js, Supabase, PostgreSQL. Multi-tenant architectures, real-time systems, marketplaces, admin dashboards, the works.
- Cross-platform mobile apps: React Native and Expo, shipped on both iOS and Android. Real-time chat, push notifications, Stripe subscriptions, in-app purchases.
- Scalable backend systems: APIs built to last, authentication, payments, cloud infrastructure on AWS and Google Cloud, CI/CD pipelines, and code that the next developer can actually read.
A few things from recent work:
- An AI content platform that cut manual editorial work by 65%, what used to take 8 hours now takes under 2.
- A marketplace scaled to 12,000+ active users with multi-vendor payments and role-based dashboards.
- A React Native app live on both iOS and Android within 10 weeks, with real-time messaging and subscription billing.
- A healthcare platform that onboarded 3,000+ users in its first 90 days, with video consultations and HIPAA-aligned data handling.
- A workflow automation tool similar to Zapier, now processing 50,000+ automated tasks per month.
- Industries I've worked across:
SaaS, EdTech, FinTech, healthcare, logistics, creator economy, travel, social networking, and e-commerce.
What working with me actually looks like:
I take full ownership from architecture to launch; not just the tickets assigned to me. I flag problems early, write maintainable code, communicate clearly throughout, and stay accountable after delivery.
If you're building a SaaS product, AI application, or mobile app and want an honest take on what it would take to do it right; send me a message. I usually respond within a few hours.

With over 10 years of experience as Full Stack Developer building and scaling production systems that support real businesses and real revenue, I’ve helped clients save time and reduce operational headaches so they can focus on growing their business instead of dealing with bugs, downtime, scalability issues, or poor code quality. As a Full Stack Developer I also leverage AI tools across my workflow to accelerate development, improve iteration speed, and streamline implementation, while still maintaining strict engineering practices around review, structure, and production readiness.
Over the years, I’ve worked with startups, scaling companies, and long-term clients, including partnerships that have lasted multiple years. My experience as a Full Stack Developr spans full-stack development, backend systems, AI integrations, cloud infrastructure, and software architecture for complex and evolving products, including multi-tenant SaaS platforms designed to support multiple clients within a single scalable architecture. As a Full Stack Developer, I have built and maintained APIs, real-time systems, SaaS platforms, internal tools, and automation workflows across production environments.
My core technology stack includes
Full Stack Development - JavaScript, TypeScript, React, Next.js, Node.js, Express, Nest.js, Python, API Development, API Integration, PostgreSQL, MongoDB, MySQL, HTML5, CSS, Tailwind CSS, Docker, Amazon Web, Services (AWS), Django, FastAPI, AI App Development, AI Agent Development

In today’s environment, speed matters, but correctness matters more.As a Full Stack Developer I use AI-assisted development tools to accelerate delivery, but every solution still goes through structured design, validation, testing, and iteration to ensure it is production ready. Every full stack developer knows that delivering features quickly is only valuable when they are reliable, maintainable, and scalable.
The result is fewer surprises, fewer rewrites, and less time spent managing development so you can focus on growth instead of firefighting technical issues. My approach as a Full stack developer emphasizes long-term maintainability, clean architecture, and business value over short-term fixes.
Whether you need a Full Stack Developer to build a product from the ground up, modernize an existing application, optimize backend performance, or integrate AI capabilities into your platform, I bring both technical depth and practical business understanding. As a full stack developer, I work comfortably across the frontend, backend, databases, cloud infrastructure, and deployment pipelines to deliver complete solutions.
Clients choose me not only as a Full Stack developer, but as someone who takes ownership, communicates proactively, and delivers production-ready software that continues to scale as their business grows.
If you are looking for a Full Stack Developer who can act as a long-term technical partner and take ownership of building reliable systems, I would be happy to connect. Whether you need a senior full stack developer for an ongoing engagement or a critical project, I am ready to help.
