My responsibilities included frontend and backend development, API integration, database architecture, authentication, and deployment. I implemented AI-driven workflows to automate proposal generation, improve productivity, and reduce manual work. The project was built using modern web technologies, including React, Next.js, TypeScript, Node.js, PostgreSQL, Tailwind CSS, Vercel, and AI development tools such as Claude Code and Cursor. The result is a fast, responsive, and scalable SaaS application designed to help businesses create high-quality proposals in minutes.
