    paper Simple Biodata Maker – Bootstrapped SaaS Product with Organic Growth & Revenue

    Designed, developed, and launched Simple Biodata Maker, a self-funded SaaS platform that enables users to create professional marriage biodatas online without requiring design skills or software installation.

    As the sole product engineer, I owned the complete product lifecycle including market research, UX design, frontend and backend development, payment integration, SEO strategy, deployment, analytics, customer support, and ongoing product improvements.

    The platform serves users across India with multilingual support and has achieved consistent organic traffic growth through SEO-driven content and product optimization. The product generates recurring revenue through a self-service purchase flow and operates with minimal manual intervention through automation.

    Technologies used include React, Next.js, Node.js, TypeScript, PostgreSQL, AWS, Cloudflare, payment gateway integrations, analytics, and automated deployment workflows.

    This project demonstrates my ability to identify market opportunities, build production-ready software from scratch, acquire users organically, and operate a revenue-generating digital product independently.
