Software Engineer

Hi, I'm Hitesh. I build web products, APIs, and AI-powered developer experiences.

My work spans TypeScript applications, Python services, and practical AI development with FastAPI, LLM tooling, and document-centric workflows. This page is an evolving snapshot of the products, prototypes, and experiments I am building.

Skills

Core technologies

Frontend

TypeScript, React, Next.js, responsive UI development, and modern component-driven product delivery.

Backend & APIs

Node.js, Python, FastAPI, API design, data modeling, and backend workflows built for iteration and scale.

AI development

LLM integrations, agent-style workflows, semantic search ideas, and AI features connected to real product use cases.

AI Focus

Building with Python, FastAPI, and applied AI tooling

Python + FastAPI

I have been using Python and FastAPI for lightweight service prototypes, typed request models, and API-first experiments that are easy to test and evolve.

LLM and agent workflows

My recent work includes hands-on experimentation with LangChain, OpenAI and Anthropic model integrations, and agent-style flows for question answering and task automation.

RAG and document intelligence

I am especially interested in document ingestion, semantic search, citations, and AI chat experiences that help users retrieve and reason over knowledge more effectively.

Experience

What I bring

Full-stack implementation

I enjoy taking ideas from concept to working software, from backend APIs and AI workflows to polished frontend delivery.

Modern backend engineering

Alongside TypeScript systems, I have been expanding into Python and FastAPI for AI-oriented services and rapid backend prototyping.

Continuous AI exploration

I regularly explore LLM tooling, RAG patterns, and ML-adjacent product ideas through practical hands-on projects.
