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.

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.

Anthropic filed its S-1 on 2026-10-26. Past the headline loss, the filing says Claude wrote over 90% of its code contributions, flags copyleft risk in AI-written code, calls MCP donated to the Linux Foundation, and measures cost per task. What the table says, what the risk factors say, and what is still blank.

Moonshot's Kimi K3.1 Pro scores 55 on Artificial Analysis, behind only Claude Opus 5.5, and promises open weights by Nov 4. What it is, how to call it from an app (thinking always on, sampling fixed), whose benchmarks those are, and what is still unknown.
