# Mandeep Singh on Tal

## Headline

Full\-Stack \+ AI Engineer \| Shipped REST APIs to prod at a startup \| LangGraph agents, provider\-agnostic LLM layer \| LeetCode 1700\+ \| Open to Internships

## About

By the end of my internship at Corporate Cruise, I had 6\+ REST APIs running in production written, reviewed, and shipped within my first month\. I build full\-stack systems that actually do something\. On the backend that's FastAPI, Node\.js, and Express\. On the frontend, React and Next\.js\. For AI work, I reach for LangChain and LangGraph, and I've integrated OpenAI, Anthropic, Groq, and Gemini APIs into production backends\. Databases MongoDB and Redis for most things, MySQL when the schema demands it\. Docker for everything that needs to not break on someone else's machine\. At Corporate Cruise, a seed\-stage startup, I replaced a manual payment and email process by integrating third\-party APIs end\-to\-end cut transaction handling time by 60%\. I also plugged OpenAI and LangChain into the backend to power AI features that shipped to real users\. Not a demo\. Real users\. My flagship project is TAILORAI a multi\-agent resume customization system I built with LangGraph, FastAPI, Next\.js, and Docker\. The core idea was a provider\-agnostic LLM layer: swap between OpenAI, Anthropic, Groq, or Gemini via a single YAML config with zero code changes\. The agents rewrite LaTeX resume sections against a target job description while keeping certifications immutable to prevent hallucinations\. In practice it cuts manual tailoring time by 70–80% per application\. I also do competitive programming seriously\. 1700\+ on both LeetCode and CodeChef, 500\+ problems solved\. Not because it looks good on a profile it's where I actually learned to think about tradeoffs before writing code\. I'm in my third year at Bennett University \(B\.Tech CSE, CGPA 8\.9\) and looking for SWE or AI/ML internships for 2026\. Open to relocating anywhere the work is interesting\.
