Hey, I'm Prateek, a Top-Rated Full-Stack Developer with $60K+ earned and 1,200+ hours completed on Upwork, I am helping startups and businesses build AI-powered SaaS platforms and agentic systems that actually ship to production. I specialize in the intersection of full-stack SaaS engineering and applied AI: LLM systems, agentic architecture, and the product decisions that make them reliable, not just impressive in a demo. That means designing how an agent reasons, plans multi-step actions, and uses tools, not just wiring up an API call and calling it AI. Since 2022, I've worked with global clients to build custom SaaS platforms, AI agents, REST APIs, and automation systems that solve real business problems. Clients tend to stick around; a few whiteboard sessions in, and I'm usually treated like part of the internal team, which is probably why most of my Upwork engagements run 18 months to 3 years. What I can help you with: - AI Agent & Agentic System Development - SaaS MVP Development, idea to production - Context Engineering - Retrieval Augmented Generation (RAG), Embeddings & Vector Search - AI Chatbot Development - Django / Python Backend Development - React / Next.js Applications - REST API Development - Automation Systems & AI Workflows - AWS, Docker & Cloud Deployment - Startup & Enterprise SaaS Architecture A few of these live in my portfolio below: an AI recruiter that interviews candidates itself, a maintenance agent that plans repairs from live floor plan and documentation data, a knowledge platform that reasons over a company's internal knowledge base. I also build fast. My workflow runs on AI native coding tools like Claude Code, so I can take an idea to a working MVP in weeks, without skipping architecture, tests, or security to get there. Tech Stack: Python, Django, Django REST Framework, React, Next.js, Node.js, TypeScript, PostgreSQL, OpenAI API, Anthropic API, LangChain, Vector Databases, AWS, Stripe, Celery, Docker, Git. If you're building an AI product, or want to add real agentic capability to one you already have, send me a message and tell me what you're trying to build. Happy to jump on a quick call and think it through with you.
