Hi, I'm Prathmesh
From building fullstack applications to diving deep into cloud infrastructure and GenAI, I've been on a journey of turning ideas into production ready products, one project at a time.

September 2025 - Present
Software Engineer

Took on the challenge of rebuilding a UK client's AI video generation platform from the ground up.

  • Transformed the platform into a production ready product by stabilizing pipelines and rethinking the UI/UX, helping them scale beyond $100k MRR.
  • Wore many hats across Frontend, Backend, Auth, Payments, GenAI, and AWS (Lambda, S3). The result? Monthly refunds dropped from $4.5k (Apr 2025) to $0 (Sep 2025).

Frontend Engineer

Joined a fast moving team focused on helping companies validate skills through real world assessments.

  • Shipped features across 5 client apps with 50+ merged PRs using Next.js, TailwindCSS, and AWS.
  • Had this idea for an AI chat agent that could help recruiters find candidates more effectively, so I built it.
  • Partnered with designers to craft pixel perfect UIs and landing pages. Also hunted down recording issues with IVS, bringing failures down to 0%.

I've worked on a variety of projects, from simple websites to complex web applications in Gen AI. Here are a few of my favorites. You can find my resume here

ChatUI

ChatUI

With so many great LLMs out there, I got tired of juggling subscriptions, so I built ChatUI. Bring your own API keys for any OpenAI API compatible model, and chat away with a mobile friendly PWA interface. I also added support for up to 5 team members to brainstorm together with an LLM. This project taught me a ton about optimizations and best practices, and I'm now evolving it into a Microservices architecture with a Go backend and Python for LLM logic. Over 140 users and counting!

StockGPT

StockGPT

I wanted a smarter way to analyze stocks, so I built StockGPT, an intelligent terminal based tool that uses LLMs with tool calling to fetch real time financial data via yfinance. Powered by LangChain and Gemini 2.0 flash, you can ask natural language questions and get insights across 125 different stock related values. I also added plotly graph objects to visualize and compare multiple stocks over time in interactive plots.

Twitter Clone

I wanted to sharpen my UI development skills and explore GraphQL as a different way to talk to backends, so I built a Twitter clone. Used Next.js for the frontend, Node.js for the backend, and Prisma ORM for PostgreSQL. Added Redis for caching and rate limiting, plus Google OAuth for auth. Deployed it on AWS in a scalable setup. (The instance might be offline since there aren't active users, but the code's all there!)

PDFQuery

Ever wished you could just ask questions about a PDF and get answers? That's PDFQuery. Built with RAG, it uses LangChain for language processing and FAISS for similarity search. The interface is a simple Streamlit app powered by Python, and it runs on the gemini-flash-2.0 model via the Gemini API.
