About Riajul
Full-Stack Engineer (MERN) | DevOps & Cloud Deployment
Dhaka, Bangladesh - 8:43 am local time
I work across the entire development lifecycle: system design, frontend engineering, backend APIs, database architecture, DevOps automation, performance optimization, and infrastructure scaling. My focus is on building maintainable, secure, and future-ready systems.
I have hands-on experience developing multi-tenant SaaS platforms, ERP systems, dashboards, and e-commerce ecosystems that manage complex business logic and high traffic.
What I can help you with
• Full-stack web application development
• SaaS and multi-tenant platform architecture
• Secure REST API design and backend engineering
• Performance optimization and scalable system design
• CI/CD pipeline setup and containerized deployments
• Admin panels, dashboards, and business systems
• Real-time systems (chat, notifications, live updates)
• Database design and high-performance data modeling
Backend & DevOps Strengths
• Redis caching for performance optimization and reduced database load
• Role-Based Access Control (RBAC) with granular permission systems
• API rate limiting using Token Bucket and other traffic-control strategies
• Secure authentication systems (JWT, OAuth, OTP flows)
• Background job processing and asynchronous task handling
• Request validation, abstraction layers, and clean architecture patterns
• Monitoring-friendly deployments with version control and staged releases
• Containerized infrastructure using Docker and Kubernetes
• Reverse proxy and routing using Nginx
• Linux server management and production environment setup
Technical Expertise
Frontend: React, Next.js, TypeScript, Tailwind CSS
Backend: Node.js, Express.js, MongoDB, REST APIs

Real-Time: SocketIo, WebRTC
DevOps: Docker, Kubernetes, Nginx, CI/CD pipelines, Linux servers
I build systems that are stable under load, secure by design, and ready to scale as your product grows. If you need production-quality software instead of temporary fixes, I can help you design and deliver it the right way.
