How can I hire Muddasir for my startup or company?

You can hire Muddasir directly by filling out the contact form below or emailing muddasirhaider048@gmail.com. We start with a 20-minute discovery discussion to scope your product architecture, establish milestone timelines, and provide a clear fixed-price or sprint-based quote.

Do you work with startups in the US, UK, and internationally?

Yes! Over 80% of my client collaborations are with international founders and US-based startups. I operate with seamless asynchronous updates, daily git commits, sprint demos, and flexible overlap with US Eastern (EST) and Pacific (PST) timezones.

How quickly can you build and ship a production MVP?

A complete end-to-end MVP (Next.js frontend, PostgreSQL database, authentication, Stripe/WhatsApp checkout, and AI integrations) is typically designed, developed, and deployed within 2 to 4 weeks depending on feature complexity.

What kind of AI integration and agentic systems do you build?

I engineer production-grade LLM applications using LangChain, OpenAI API, Claude API, and custom autonomous agents. Capabilities include automated document parsing, conversational recommendation engines, intelligent workflow automation, and custom RAG (Retrieval-Augmented Generation) pipelines.

Do you build mobile apps and Android APKs in addition to web platforms?

Yes, I develop cross-platform mobile apps using Flutter and React Native, delivering production-ready Android APKs and iOS binaries fully synchronized with your web backend and database.

Why hire a solo full-stack systems engineer instead of a large agency?

Hiring a solo engineer who owns the whole stack eliminates communication bottlenecks, project manager markups, and disjointed handoffs between frontend and backend devs. You get 3x faster delivery, direct founder-to-developer dialogue, and 100% accountability.
