AI Engineer — LLM Apps, Agents & Automation
I build AI-native software: LLM-powered apps, multi-agent systems, RAG pipelines and developer tools, with multi-model routing across OpenAI, Anthropic, Groq and open models.
I focus on AI that ships and holds up in production — grounded outputs, sensible fallbacks, rate limiting, cost control and honest handling of the cases where a model can't help. AI features that are useful, not just demos.
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'.

Selected work
MK QuizFlow
An AI study tool that turns PDFs, notes and images into quizzes and flashcards. Next.js App Router, Vercel AI SDK (Claude), local-first IndexedDB storage, cloud share via Vercel Blob, an Image → Quiz vision feature, rate limiting and quota. Live at thequizflow.com.
MK Router
A time-based portfolio router that reverse-proxies five portfolios on one domain, rotating hourly. Shipped on both Cloudflare Workers and Vercel Edge Middleware.
60-project ecosystem
A large ecosystem of portfolios, tools, games and web apps, consolidated to 25 flagship products, each live and deployed.
MK GitFlow
An interactive Git simulator and learning platform — type real Git commands and watch an in-memory commit graph redraw live.
What you get when you hire me
- Clean, documented, maintainable code you own
- Live deployment with a working URL
- Tests for the important behavior
- Honest status reporting — what's done, tested, and any risks
- Clear handover so your team can keep building
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 AI tools and models do you use?
OpenAI, Anthropic (Claude), Groq and open models, via the Vercel AI SDK, AI Gateway, LangChain and MCP.
Can you build an AI agent?
Yes — tool-using agents, multi-agent workflows and agentic automations are core work.
What is RAG and do you build it?
Retrieval-Augmented Generation grounds an LLM in your data; yes, I build RAG pipelines with vector databases.
How do you control AI cost and reliability?
Multi-model routing (cheap model by default), caching, quotas, rate limiting and graceful fallbacks.
Can you add AI to my existing product?
Yes — I integrate LLM features (chat, generation, extraction, vision) into existing apps.
Do you take AI engineering contracts?
Yes, remote and freelance. Reach out via contact.
