Akella Rushi Karthik · Full-Stack Developer

I build intelligent digital products that solve real problems.

Full-stack applications, AI-powered tools, and data-driven solutions built with modern technologies.

const product = build({
  idea: "real problem",
  stack: ["react", "ai", "data"],
});

Real projects I designed and built — from retrieval pipelines to full-stack chat to data validation.

01 — AI-powered document Q&A

PDF Insight

Finding a specific answer inside a long PDF means scrolling and skimming for minutes.

A retrieval-augmented pipeline that extracts and chunks PDF text, embeds it, stores it in ChromaDB and answers questions grounded in the most relevant passages.

AI Chatbot

Most simple AI chat demos forget your conversations and can't look at images.

A MERN-style chat application with image understanding, persistent conversation history and a polished, responsive chat experience.

DataSentinel AI

Missing values and duplicates quietly break analysis if no one checks the dataset first.

A FastAPI + Pandas service that inspects uploaded CSVs for common quality issues, with a TypeScript frontend to review the findings.

How I Can Help You Build

Practical, scoped work — the kind of problems I've already solved in my own projects.

Full-Stack Web Development

Problem — You need a working web app, not just a static page.

You get — Responsive frontend, backend APIs and database integration, shipped as a usable application.

AI-Powered Applications

Problem — You want to try an AI feature without a big team.

You get — AI chat interfaces, document Q&A prototypes and model/API integrations you can demo.

Data Quality & Analytics

Problem — Your dataset is messy and you're not sure you can trust it.

You get — CSV validation, data cleaning, SQL analysis and simple, repeatable data workflows.

Website Improvements & API Integrations

Problem — Your existing site has bugs, layout issues or missing features.

You get — Frontend fixes, responsive improvements, bug fixes, API connections and feature additions.

About

Learning by building.

I'm a Computer Science undergraduate who enjoys turning ideas into working applications — full-stack web apps, AI-powered tools, and data workflows on the cloud.

Most of what I know I've learned by shipping projects: wiring a RAG pipeline to answer questions about PDFs, building a chat app that remembers conversations and reads images, and writing a validator that catches messy data before it reaches analysis.

I care about solving the actual problem, keeping things simple, and leaving code that someone else can pick up.
