I build production frontends in React, Next.js and TypeScript — and the AI and MCP tooling behind them. 7+ years shipping web applications, from data modelling through to the deployed interface.
What I Do
React, Next.js and TypeScript interfaces that work on every screen, covered by unit and Playwright tests, shipped to production.
MCP servers and LLM features built into a product where they earn their place — not bolted on for their own sake.
REST and GraphQL APIs, auth, and data models built to hold up under real traffic.
Scalable architecture from database schema to microservices and event-driven systems.
Background jobs, webhooks and third-party integrations that take the manual steps out of a workflow.
AI integration strategy, code review, architecture audits
Selected Work
A solo-built content-publishing autopilot — draft once and post everywhere (LinkedIn, Threads, Instagram, YouTube) in your own voice, driven entirely from Claude Code in the terminal.
Tech Stack
A multi-tenant SaaS that runs an Indian physiotherapy clinic end to end — patient files, attendance, session packages, GST billing, prescriptions and a self-serve patient portal — from one calm, phone-first screen.
Tech Stack
A remote MCP server that turns Claude into a personal assistant — tracks habits, tasks, finances, goals, documents, and memory with semantic search. Built on OAuth 2.0 + PKCE, deployed serverless on Vercel with 41 MCP tools across 6 domains.

About
Amar Gupta
Senior Frontend Developer — AI & MCP · Delhi / Remote
I build production frontends in React, Next.js and TypeScript — and the AI and MCP tooling behind them. 7+ years shipping web applications, from data modelling through to the deployed interface.
I focus on system design, scalability, and clean architecture. I use AI tooling like Cursor and Claude Code to move faster, but the fundamentals — data modelling, error handling and tests — are what make a product hold up in production.

WRITING
Long-form notes on shipping AI products, MCP servers, and the weird edges of modern web dev.

GPT-6 Astra claimed to edit a small Qwen model's raw weights by hand — touching 0.016% of them — and send its math scores soaring. A reproduction on a laptop and a sharp critique landed a day later. Here's what was actually measured, what's marketing, and the one lesson that transfers to anyone building with AI.

Google's Gemini 4 Carbon topped the Artificial Analysis Intelligence Index at 59 — the first Google model to do it. But there's no release date, no model ID, no API: you can't build with it yet. What the coding and cost-per-task numbers actually say for anyone shipping web apps with AI, and why I'm keeping it on the watchlist, not in the stack.

Claude Fable 5.1 costs 2.5 times Opus 5.5 per token, and Anthropic's own docs say to start on Opus. Here is when Fable is worth it for a web app's AI features, the four breaking changes if you are on Fable 5, and what the GVS5H and hidden-image stories do and do not show.
