I’m Rounak Burnwal, an AI Product Builder, AI-Assisted Developer, and Digital Product Creator based in West Bengal, India. I build websites, apps, SaaS platforms, and practical tools around business needs.
I use Codex, prompt engineering, and hands-on testing to take ideas from product planning to working builds. I run Digital Bazzar, and my experience in marketing and client delivery helps me understand the customers and workflows behind each product.
A digital marketing venture I previously ran, now closed. The work brought campaigns, creative, websites, and sales funnels together around the needs of the business.
My venture for courses and digital products, connecting the offer, sales journey, payments, and customer experience.
Understand the customer, the cost, and the path to conversion before choosing the tools.
Use clear prompts, practical testing, and fast iteration while continuing to deepen my programming and backend skills.
Favor repeatable systems, recurring revenue, and efficient operations that can support a growing business.
Beyond the work I’m interested in thoughtful money management and long-term wealth building—from tracking income and expenses to learning about mutual funds, SIPs, digital gold, and emergency planning.
Understand the business, the customer, and the constraint. Consider cost, conversion, and the outcome before choosing tools.
Map the product, the customer journey, and the workflows. Connect the interface, payments, and marketing around one clear plan.
Use prompt engineering and AI-assisted development to build interfaces, improve code, debug, and connect the moving parts.
Test the product, resolve technical issues, and prepare it for deployment. Connect hosting, integrations, and payment workflows.
Review feedback, campaign performance, and operating costs. Troubleshoot, refine the customer journey, and automate repeatable work.
AI-assisted builds, ventures, and product thinking.
