Looking to build an MVP, SaaS product, mobile app, or scale your existing system? I help businesses turn ideas into fast, scalable, production-ready applications.

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.
