Hire the Best Expo.io Developers
in Pakistan

I’m Suneel, a full-stack developer who started building apps simply because the ones I wanted didn’t exist yet. What began with experimenting in HTML and CSS quickly turned into a deep passion for JavaScript, React, and product-focused development. Today, I build modern web applications and cross-platform mobile apps using React Native, backed by scalable systems with Node.js, MongoDB, and Firebase. I focus on clean architecture, smooth state management with Redux, and creating real products that are fast, intuitive, and built to scale.

You shipped the app. Now it owns you. Crashes you can't reproduce. An App Store rejection with no explanation. A cloud bill that doubled overnight. You're up at midnight patching code instead of growing the product. That handoff point is my job. I'm a senior React Native Developer and Mobile App Developer who takes over production React Native apps: React Native rescue, React Native performance optimization, App Store approval, FastAPI backends, and cloud bills cut back to what you 🏆 𝗧𝗼𝗽 𝗥𝗮𝘁𝗲𝗱 𝗣𝗹𝘂𝘀, 100% Job Success across 49 projects 📊 $100K+ earned, 4,100+ tracked hours on Upwork ⚡ 40+ mobile apps and web applications shipped end to end 🔥 One React Native AI app serving 100,000+ users in production today 𝗪𝗛𝗢 𝗛𝗜𝗥𝗘𝗦 𝗠𝗘 ⚡️ Founders whose app grew faster than the code. Users are showing up. The crashes showed up with them ⚡️ Teams whose previous React Native developer left a half-built Expo or Next.js product behind ⚡️ Founders with a vibe-coded MVP (Cursor, Lovable, Bolt, Replit, v0) that demos great and breaks in production ⚡️ Startups whose codebase won't survive technical due diligence before a raise ⚡️ Product teams starting a React Native mobile app that must be production-grade from day one, because they've been burned before 𝗪𝗛𝗔𝗧 𝗜 𝗙𝗜𝗫 ⚡️ React Native Rescue: I take over legacy and AI-generated React Native codebases, tell you honestly what's worth keeping, and stabilize before scaling. Most apps don't need a rewrite. They need an engineer ⚡️ React Native Performance Optimization: the crash that only happens on Android. The list that janks at 200 items. Re-render storms from MobX and state management done wrong. I find it, I fix it, you watch the crash reports go quiet ⚡️ App Store Compliance: rejections decoded, TestFlight rollouts, provisioning untangled, resubmitted and approved ⚡️ Cloud Bill Reduction: Google Cloud and Firebase bills usually grow from bad queries, not growth. I find the N+1 reads and runaway functions and cut the bill down to what the product actually needs ⚡️ React Native AI Integration: as an AI Developer I build assistants, voice features with Whisper, and LLM features with OpenAI and Claude that behave with real users, not just in demos ⚡️ React Native FastAPI Backend: as a FastAPI Developer I own the Python APIs, PostgreSQL, background jobs, Docker deployments, and Google Cloud infrastructure behind the mobile app. One developer, whole product ⚡️ React Native Mobile App Development: when you need it built right the first time. Production React Native CLI and React Native Expo builds for iOS and Android, TypeScript throughout, store-ready 𝗥𝗘𝗔𝗟 𝗣𝗥𝗢𝗝𝗘𝗖𝗧𝗦 🔶 React Native AI coaching app: Whisper, OpenAI, FastAPI, Firebase, Google Cloud. Multi-brand architecture, 100,000+ users, still maintained by me today 🔶 React Native rescue: previous developer gone, CI broken, database broken, auth broken. Migrated repos, stabilized production, then shipped new features on top 🔶 React Native performance audit: diagnosed MobX rendering problems as an external React Native consultant, reviewed architecture and PRs. Performance jumped. No rewrite needed 🔶 Internal engineering systems: automation on Google Kubernetes Engine, Playwright infrastructure, Slack and CRM integrations 𝗦𝗧𝗔𝗖𝗞 ⚡️ Mobile App Development: React Native, React Native Expo, TypeScript, JavaScript ⚡️ Web App Development: Next.js, React, SaaS ⚡️ Backend Development: FastAPI, Python, Node.js, Docker, GitHub CI/CD ⚡️ Cloud Infrastructure: Google Cloud Platform (GCP), Firebase, PostgreSQL ⚡️ AI Development: OpenAI, Claude, Whisper, LLM integration, semantic search 𝗛𝗢𝗪 𝗜 𝗪𝗢𝗥𝗞 ⚡️Straight answers first: send your repo or live app, and within hours you know what's broken, what's salvageable, and what it costs to fix. Before you spend anything ⚡️ Communication that doesn't disappear: daily updates, standup calls if you want them, no 12-hour silences ⚡️Ship and stay: TestFlight, App Store and Play Store submission, documentation, monitoring. Around 90% of my clients come back. The difficult part is exactly why they hired me 𝗡𝗘𝗫𝗧 𝗦𝗧𝗘𝗣 Tell me where it hurts. Repository, live app, or two sentences about what's breaking.

⚡ Senior Full Stack Developer | 9 Years | MERN Stack, Next.js, React Native, Node.js 🎯 Real Products, Real Users, SaaS Platforms, MVPs, Websites & Mobile Apps 💎 React, Node.js, MongoDB, PostgreSQL, TypeScript, Stripe, OpenAI, AWS, Docker 🔐 Startups & Founders Trust Me With Their Most Sensitive Products Let me tell you how this usually goes. A founder comes to me with an idea and a few screenshots saved on their phone. Either they haven't started, or they started with someone who left things half-built and fully confusing. Somewhere in there they stopped trusting the process. That's when I get the message. I'm Anas. 9 years building what a product actually needs, SaaS platforms, startup MVPs, websites, backend systems, mobile apps. Not demos. Not "works on my laptop." Real platforms built with React, Next.js, Node.js, MongoDB, PostgreSQL and React Native, handling real data, opened by real people every day. Here's how I work: I don't touch code until I understand what you're building and why. Sounds obvious, but most delays trace back to someone skipping that step. I ask questions first, then build, whether that's a Next.js frontend, a Node.js backend, or a React Native app for iOS and Android. And something I'm proud of: clients don't come to me because I'm the cheapest name on the list. They come because someone told them the work holds up. 📖 THE KIND OF WORK I'VE DONE AI-powered SaaS platforms, including an EHR for mental health practitioners trusted by real therapists. HIPAA, HITRUST, PCI and PIPEDA compliant, with AI-generated clinical notes through the OpenAI API, encrypted telehealth video, scheduling, and Stripe billing, all working as one product. School management platforms with Next.js, TypeScript and Node.js, enrolment, classes, attendance, grading, with separate role-based access for admins, teachers, students and parents, on a MongoDB schema built to hold up under daily use. React Native apps live on Google Play and the App Store, fintech wallets, escrow platforms, coaching apps and more, each running off one shared codebase so nobody paid twice for the same work. Beyond that: websites, backend systems, admin dashboards, APIs. If it's React, Next.js, Node.js, or deployed on AWS, Vercel or Docker, it's work I do regularly, not occasionally. 🛠️ WHERE I ACTUALLY ADD VALUE SAAS, MVPS & FULL WEBSITES From a founder's first MVP to a scaled SaaS platform, React, Next.js, Node.js, MongoDB or PostgreSQL, built to launch fast and hold up once real users arrive. Websites, dashboards, internal tools: if it needs a frontend and backend working together, I build it end to end. SENSITIVE DATA? I'VE BEEN THERE Health records, student information, payment details. If your product touches any of it, compliance isn't optional and I know it. Role-based access, encryption, proper Node.js and database architecture, built in from day one, not bolted on later. ONE BACKEND, EVERY PLATFORM Web and mobile don't need two teams building the same thing twice. I build the Node.js backend once, properly, then connect your Next.js site and React Native app to it. Your budget goes to growth, not duplication. AI THAT ACTUALLY DOES SOMETHING I don't bolt on AI so a product can say it "has AI." Using the OpenAI API I've built AI that turns real therapy sessions into structured clinical notes automatically. Useful, not decorative. APIS AND BACKENDS THAT DON'T FALL APART Node.js and Express APIs, MongoDB or PostgreSQL schemas designed properly the first time, REST or GraphQL depending on what fits. Built to last, not to be rebuilt in six months. 💬 WHAT A CLIENT TOLD ME "He understood the requirements quickly, suggested practical improvements where needed, and handled both the frontend and backend efficiently.

I fix broken React, Next.js, and React Native apps usually within 24–48 hours and build SaaS MVPs that survive real users. Over the last 2+ years I've delivered 38+ client projects: bug rescues, full dashboards, Stripe billing systems, and App Store / Play Store deployments with repeat clients across the US and Europe (verified testimonials below). Most clients come to me in one of three situations: 🟢 The Green Field — They need a SaaS MVP built properly from the ground up. 🟠 The Manual Mess — Their workflows need AI, n8n/Make automation, or API integrations. 🔴 The Product Rescue — They have an app, but the backend, React Native build, or Stripe logic is breaking under real-world use. ━━━━━━━━━━━━━━━ WHAT I BUILD SaaS MVPs (Web & Mobile) The "engine" of your startup using MERN (React, Next.js, Node, MongoDB) and React Native: Secure auth & role-based access (JWT, Firebase) Scalable dashboards & admin panels (Tailwind, Ant Design) Stripe subscriptions, billing logic, and webhooks iOS + Android apps from a single codebase, shipped to both stores AI & Business Automation Replacing manual work with automation that saves founders 20+ hours a week: n8n, Make, Zapier, Airtable, OpenAI APIs Lead routing, client onboarding, CRM syncing Custom API integrations between your tools Product Rescue & Bug Fixing My specialty.
