Aman D.

I build and scale AI-powered SaaS products and modern web applications using React, Next.js, TypeScript, Python, FastAPI, Django, and Node.js. With 9+ years of full-stack development experience, I work across frontend, backend, APIs, databases, AI integrations, and production systems - from building new products to improving existing applications. I’m especially comfortable joining an existing codebase where the architecture, designs, APIs, and business requirements are already defined, then taking ownership of features, integrations, bug fixes, performance improvements, and production delivery. 𝗔𝗜 + 𝗟𝗟𝗠 𝗗𝗘𝗩𝗘𝗟𝗢𝗣𝗠𝗘𝗡𝗧 I build practical AI features and LLM-powered applications using OpenAI, Claude, Gemini, RAG, AI agents, LangChain, LangGraph, vector databases, embeddings, semantic search, tool/function calling, AI assistants, and workflow automation. 𝗙𝗨𝗟𝗟-𝗦𝗧𝗔𝗖𝗞 + 𝗦𝗔𝗔𝗦 React, Next.js, TypeScript, Python, FastAPI, Django, Node.js, REST APIs, PostgreSQL, MongoDB, AWS, Docker, CI/CD, authentication, third-party integrations, dashboards, marketplaces, SaaS platforms, and business workflows.
