About Rounak
Backend Architect | Node.js, NestJS, Microservices, AWS | Scalable Saa
Kolkata, India - 11:20 am local time
Since 2021, I’ve been building backend systems that support real users, real payments, and real business workflows. I’ve worked in multiple startup environments, helping founders move from idea to production quickly while keeping the system scalable and secure.
My main stack is Node.js, NestJS, AWS, MySQL, and MongoDB, and I also use AI tools in my development workflow to speed up delivery and reduce overall project cost.
Here’s how I usually help my clients:
• Design and build scalable backend architecture
• Develop REST APIs and microservices
• Set up cloud infrastructure and deployment on AWS
• Work with MySQL and MongoDB, including performance optimization
• Integrate authentication, payment gateways, and third-party APIs, OAuth 2.0
• Build backend systems for mobile and web applications
• Support MVP and SaaS product development
I’ve delivered backend systems and products for several startups, including Clusive, Better Bee, Axia, and Vaccau, and I’m currently working with Synclink. My work has included salon booking platforms, payment integrations, real-time applications, and SaaS products used by real customers.
I focus on writing clean, scalable, and maintainable code, and I believe clear communication is just as important as technical skills. Many teams I’ve worked with continue long-term because I try to understand the business goals, not just the technical requirements.
If you’re building a startup, SaaS, or mobile product and need a reliable backend engineer who can think about architecture, scalability, and long-term growth, feel free to reach out. I’m always happy to discuss ideas and suggest the best technical approach.
