Syed Rahman — Senior React Native + AI Mobile Engineer | Freelance Mobile Developer
Available — open to new engagements

I ship AI-integrated React Native apps for founders who need to move fast.

Senior mobile engineer with 7 years of production experience. I specialize in integrating LangChain, OpenAI, and RAG patterns into React Native — and I have three apps live in the App Store and Play Store to prove it.

Currently
Developing production apps for the App Store and Play Store and working as a freelance mobile app developer. Available for founders and teams across US, Canada, and EU timezones.

Three apps shipped in the last eighteen months.

Four ways to engage, depending on what you actually need.

AI integration

Add LangChain, OpenAI, RAG patterns, embeddings, or on-device LLMs to your existing mobile app. I've shipped all of these in production and know what actually works on phones — versus what looks good in a demo.

For teams adding AI to an existing product

Feature sprints

Ship a specific feature in two weeks. Clean architecture, no scope creep, production-grade code your team can maintain. Async-friendly with clear daily updates.

For teams with capacity issues and clear scope

Ongoing retainer

Senior mobile engineer embedded with your team. Flexible weekly commitment matched to what your roadmap actually needs. Best for funded startups without a full-time mobile lead.

For funded startups, 6+ month engagements

MVP from scratch

Take an idea to a live App Store app. AI integration, monetization, store submissions, the whole path. Fixed scope, fixed timeline, no surprises.

For non-technical founders with a clear vision

A senior engineer who's done the work.

I'm a senior mobile engineer focused on integrating AI into React Native apps. Over the last 18 months I've shipped three production apps — each using OpenAI, LangChain, and RAG patterns in different ways. Architecture-first, no shortcuts, code your team can actually maintain after I'm gone.

Before going independent, I worked on production Android apps used by millions, including infotainment systems for General Motors vehicles and the national grocery app at Loblaws Digital. Now I build my own products and take on one or two contract engagements at a time for teams that need a senior pair of hands.

I currently work as a freelance mobile app developer, building production apps for the App Store and Play Store. I keep my client list short on purpose — when we work together, you have my full attention.
