AI Frontend Engineer — LLM Interfaces & Generative UI
I build the interface layer for AI: streaming chat UIs, generative interfaces and agent-driven UX that make LLMs feel fast, clear and trustworthy — with React, TypeScript and the Vercel AI SDK.
AI products live or die on the interface. A great model with a confusing UI feels broken; a modest model with a thoughtful UI feels magical. I specialize in that layer — streaming, tool surfaces, loading and error states, and UX that sets honest expectations.
How I work
- Understand. I start with the real problem, users and constraints — not a feature list. A short discovery avoids building the wrong thing.
- Plan. A clear plan: scope, non-goals, the approach, and how we'll verify it works. You always know what's being built and why.
- Build. Small, tested, verifiable increments. Working software early and often, with clean, maintainable code that follows the project's conventions.
- Ship & verify. Real deployment, real testing, honest reporting. I verify behavior end-to-end before calling anything done — no 'it should work'.

Who I work with
Founders & startups
Building an MVP or first product and need someone who can ship the whole thing quickly, then iterate as you learn.
Small teams
You have a team but need extra capacity or a specialist to own a hard piece and deliver it end-to-end.
Agencies
You need a reliable contractor who communicates clearly, hits scope, and produces code your team can maintain.
Solo operators
You have an idea and a budget but no engineer — I can take it from concept to a live, working product.
Ways to work together
- Fixed-scope projects — a defined build with a clear deliverable and timeline
- Contract / part-time — ongoing capacity for a set number of hours
- Rescue & improvement — take over, stabilize and extend an existing codebase
- Advisory — architecture, code review and technical direction
I'm Musharraf Kazi (also known as Kazi Musharraf or MK Knight), a developer based in India working with clients worldwide, remote-first across time zones. Whether you need a one-off build or an ongoing engineering partner, the priority is the same: ship real, working software and report on it honestly.
Frequently asked questions
What is an AI frontend engineer?
Someone who builds the user-facing side of AI products — chat, streaming, generative and agent UI — not just the model.
What stack do you use for AI UIs?
React/Next.js + TypeScript with the Vercel AI SDK for streaming and tool calls.
Can you design AI chat experiences?
Yes — conversational UX, streaming responses, tool/agent surfaces, and clear error and empty states.
Can you connect a UI to my model or API?
Yes — I wire frontends to LLM APIs, agents and RAG backends, handling streaming and state.
Why does AI UX matter so much?
Because trust and clarity come from the interface — good UX turns a capable model into a product people rely on.
Available for remote work?
Yes. Contact me with your project.
