Rajiv R.

Backend Developer | Python, FastAPI, Next.js, React & AI Integration

I build web applications, internal business tools, and AI-powered features using Next.js, React, Python, and FastAPI. Whether you need a customer dashboard, an internal management system, a custom web application, or an AI feature integrated into an existing product, I can help take it from requirements to a working implementation. 📋 What I can help you build: - Full-stack web applications and dashboards - Internal tools, inventory systems, and customer management systems - REST APIs, backend services, and database integrations - AI-powered features, assistants, and document-processing workflows - Business automation and integrations between existing tools - Improvements, bug fixes, testing, and deployment for existing applications Some of my relevant work: 📖Kantigo — AI Learning Management System I developed and deployed a learning platform that generates structured courses and lessons based on users' learning goals. It combines a Next.js frontend, database, authentication, and AI content-generation workflows. 💼 Business Websites and Internal Systems I'm working on a company website redesign and developing inventory and customer management systems alongside a UX colleague. 💻 AI Development and Integrations At a biotech R&D startup, I developed AI agents, external API integrations, and evaluation systems. I also built a centralized benchmarking platform used to assess agent quality and readiness for production. My main tools include Next.js, React, TypeScript, Python, FastAPI, PostgreSQL, Supabase, Docker, MCP, and modern AI APIs. I prefer starting with a clear scope, agreeing on useful deliverables, and building something that can be tested and maintained rather than just demonstrated. If you have an existing application that needs improvement or a new tool you want to develop, I'm happy to discuss a small first milestone.
