🧠 About Me (Human Mode)

I'm a Full Stack & AI Engineer who turns:

📦 legacy systems → ⚡ cloud-native platforms → 🤖 self-correcting AI agents

I work across:

  • 🏗️ Enterprise full stack — .NET, Java, Spring Boot, React, Angular
  • ☁️ Cloud infrastructure — Azure AKS, Cosmos DB, Kafka, AWS
  • 🤖 Agentic AI — LangGraph orchestration, RAG pipelines, local LLMs
  • 🔐 Security — JWT, OAuth 2.0, RBAC, ASP.NET Identity

Mission: Build systems that don't just respond — they plan, retrieve, verify, and act.

📂 Featured Projects (Boss Levels Unlocked)

Projects GIF


🤖 ResearchFlow AI — Self-Correcting Research Agent

Research GIF

  • LangGraph multi-node orchestration: Planner → Decomposer → Search → Verifier → Synthesizer
  • Web evidence retrieval via Tavily Search API
  • Confidence-scored retry logic when evidence quality is low
  • Citation-grounded answers — no hallucinated sources
  • FastAPI backend · React frontend · Ollama local LLM
🤫 How many nodes in the graph?

Five. Each with a very specific job.
The Verifier's job is to distrust everyone else.
It's the most relatable node.


📄 DocuMind — RAG Platform with Eval Harness

Docs GIF

  • Semantic search over documents via Pinecone vector DB
  • GPT-4 generation grounded only in retrieved context
  • LlamaIndex RelevancyEvaluator — actual quality measurement, not vibes
  • Sub-second retrieval latency
  • FastAPI · React · PyPDF2 · SQLAlchemy
🧪 Did you actually measure quality?

Yes. With an eval harness.
Not just "it seems good."
Revolutionary concept, I know.


🌐 ContextFlow AI — Privacy-First Local LLM Chrome Extension

Extension GIF

  • Zero cloud API calls — fully local Ollama + Llama 3.2 inference
  • Chrome Manifest V3 service worker as persistent agent runtime
  • Summarize pages · Ask questions · Explain highlighted text inline
  • Floating on-page explanation panel — no tab switching
  • TypeScript · React · Tailwind CSS · Vite
🔐 Is this actually private?

Your data never leaves your machine.
Not even to me.
Especially not to me.


🚍 APSRTC Duty Management Portal — Enterprise Workforce Platform

  • Spring Boot backend · Spring Security · JWT auth · RBAC across 5 roles
  • React + TypeScript frontend · Redux Toolkit · Swagger-documented REST APIs
  • Hibernate ORM · PostgreSQL schema design · Docker containerization
  • Operational efficiency improved 40%
🚌 Why buses?

Because 40% operational efficiency improvement looks great on a resume.
Also, buses are underrated.

🥚 Final Easter Egg (you earned it)

You scrolled all the way down.
Respect.

Here's what you should know:
I ship things. I measure things. I fix things when they break at 3am.
I build AI agents that self-correct — which is more than I can say for most software.

Open to Full Stack SWE and AI Engineer roles — onsite, hybrid, or remote anywhere in the US.
F-1 OPT. Available immediately.

Let's build something. 🚀


"A single-prompt LLM is a calculator. An agent with a plan, tools, and a verifier — that's a system."
