Project details
Experienced backend developer specializing in cloud-native, serverless, and scalable backend solutions. I build robust APIs, secure authentication systems, and database-driven backends for web and mobile applications. Whether you need a new backend, API integrations, or improvements to an existing system, I deliver clean, maintainable, and production-ready code.
I work with Node.js, NestJS, and Express, and can deploy on AWS, Vercel, DigitalOcean, or your preferred cloud platform. Your backend will include REST or GraphQL APIs, database models, server-side logic, authentication, and third-party integrations. I also provide CI/CD pipeline setup, performance optimization, and security best practices to ensure your backend is fast, secure, and scalable.
Every project includes complete documentation and post-delivery support. My goal is to provide a backend that is reliable, maintainable, and ready to scale with your business, whether it’s a small MVP, SaaS platform, or enterprise-level application. Let’s build a powerful backend solution that meets your needs and grows with your product.

Full Stack Developer Needed – NestJS, Next.js, PostgreSQL, Redis (Existing App Improvements)
Mosa is a highly skilled senior developer who quickly identified and resolved issues in my full-stack application. He has a strong understanding of full-stack development and system architecture, which enables him to diagnose problems efficiently and implement reliable solutions. His deep knowledge of the overall application structure allows him to work effectively on both feature development and bug fixes. Communication was smooth and the work was delivered with high quality. Highly recommended.

Job Success
Islamabad, Pakistan - 12:04 am local time
I’m a Full Stack & Mobile App Developer (AWS Certified Solutions Architect) with 5+ years of experience building and optimizing high-performance web and mobile applications, SaaS platforms, dashboards, and real-time systems.
I don’t just write code — I handle end-to-end product development from frontend and backend to cloud infrastructure and deployment.
WHAT I DO
- Build MVPs (Web & Mobile) from idea to production
- Develop scalable SaaS applications and dashboards
- Build cross-platform mobile apps using React Native
- Fix bugs, performance issues, and unstable systems
- Design backend architecture, APIs, and microservices
- Set up cloud infrastructure (AWS, Hetzner), CI/CD, and deployments
PERFORMANCE & SCALING
I specialize in improving slow and poorly built systems:
- Optimize backend logic and database queries (PostgreSQL, MongoDB, MySQL)
- Implement caching (Redis, React Query) to reduce server load
- Improve Next.js performance (SSR, SEO, rendering)
- Reduce API calls and improve response times
- Refactor legacy codebases into scalable architectures
- Use Docker for containerization and efficient deployments
REAL-WORLD EXPERIENCE
Worked on:
- Job Portals
- E-commerce Platforms
- Garage Management Systems
- Fleet Management Systems (maps, real-time tracking)
- Project Management Systems
- AEDMS (Emissions Data Systems)
Delivered performance improvements, reduced server costs, and improved user experience across production applications.
TECH STACK
- Frontend: React, Next.js, Tailwind CSS
- Mobile: React Native
- Backend: Node.js, NestJS, Express (MERN Stack)
- Database: PostgreSQL, MongoDB, MySQL, Sequelize
- Tools: React Query, Zustand, WebSockets, Redis
- Cloud/DevOps: AWS (EC2, S3), Docker, CI/CD, Hetzner
WHY CLIENTS WORK WITH ME
- Full ownership: Web + Mobile + Backend + Cloud
- Clean, scalable, production-ready code
- Strong focus on performance and architecture
- Clear communication and realistic timelines
- Long-term support and reliability
You’re not hiring just a developer — you’re working with a technical partner who can take your idea from MVP to scale.
Steps for completing your project
After purchasing the project, send requirements so Mosa can start the project.
Delivery time starts when Mosa receives requirements from you.
Mosa works on your project following the steps below.
Revisions may occur after the delivery date.
Requirement Gathering & Discussion:
I start by understanding your project goals, required features, APIs, and database needs. If you have an existing backend, database schema, or design files, I review those to ensure we build on a solid foundation.
Planning & Architecture:
Next, I define the backend structure, database schema, API endpoints, and cloud setup. I also decide whether a serverless, microservices, or monolithic architecture is best suited for your project.
