I build scalable full-stack web applications and SaaS platforms using React.js, Node.js, Express.js, PostgreSQL, Redis, and TypeScript.
I have hands-on experience developing production-grade B2B SaaS systems including admin dashboards, RBAC authentication systems, analytics dashboards, financial modules, REST APIs, and high-performance bulk processing workflows.
My expertise includes:
• React.js frontend development
• Node.js and Express.js backend APIs
• PostgreSQL database design and optimization
• User Roles & Permission Systems
• Admin dashboard development
• SaaS platforms and multi-tenant systems
• API implementation and issue resolution
• Redis and BullMQ queue processing
• Performance optimization and scalability improvements
I focus on clean architecture, responsive UI, fast delivery, and production-ready code. I can help startups and businesses build, maintain, optimize, or extend modern web applications efficiently.
Available for long-term collaboration, feature development, bug fixing, and SaaS maintenance projects.
