I built Somalia's first mobile wallet. I run a 50-engineer studio. And I still personally take on select Upwork projects — React Native, Next.js, and AI woven into the actual product, not bolted on top of it. 𝟵𝟬𝟬+ 𝗮𝗽𝗽𝘀 𝘀𝗵𝗶𝗽𝗽𝗲𝗱. $𝟱𝟬𝟬𝗞+ 𝗲𝗮𝗿𝗻𝗲𝗱. 𝗧𝗼𝗽 𝗥𝗮𝘁𝗲𝗱 𝗣𝗹𝘂𝘀.
𝗙𝗥𝗘𝗘 𝟯𝟬-𝗠𝗜𝗡 𝗖𝗢𝗡𝗦𝗨𝗟𝗧𝗔𝗧𝗜𝗢𝗡.
Tell me your idea, I'll tell you what to build first, what to skip, and what it actually takes. No pitch deck. No sales call disguised as a favor.
𝗣𝗥𝗢𝗗𝗨𝗖𝗧𝗦 𝗜'𝗩𝗘 𝗔𝗖𝗧𝗨𝗔𝗟𝗟𝗬 𝗦𝗛𝗜𝗣𝗣𝗘𝗗:
— not portfolio mockups, live and downloadable:
— T-Plus / SomBank — Somalia's first mobile wallet (ISO 27001, Mastercard)
— Charter — group-first social platform, iOS and Android
— ZahraPay — mobile payments, on the App Store
— Nvois — invoicing and billing, on the App Store
— Accounty — accounting platform
— Cuddy, AngelsBird, Life-Match — dating and matching apps, live on the App Store
— Timezzi, Proposal App, Vehicle Transport Hub — SaaS on-demand platforms
As CEO of 𝐆𝐥𝐨𝐰𝐢𝐧𝐠𝐬𝐨𝐟𝐭 𝐓𝐞𝐜𝐡𝐧𝐨𝐥𝐨𝐠𝐢𝐞𝐬, I lead 50+ engineers — but for Upwork work, I stay hands-on personally. You're not getting handed off to whoever's free that week. You're getting the person who's shipped this before, still writing the code.
𝗪𝗛𝗔𝗧 𝗜 𝗗𝗢:
— AI integration: not a chatbot bolted onto your homepage. Semantic search, recommendation engines, and RAG pipelines that actually change how users find and buy.
— Full-stack mobile apps: React Native, one codebase, both app stores, no compromise on native feel.
— Web app development: Next.js and React on the frontend, MERN or MEAN on the backend — whichever your stack already speaks.
— Backend & APIs: Node.js, Express, REST, GraphQL — built for real traffic, not a demo.
— UI/UX & mockup design: wireframe to production screen, so you're not coordinating between a developer and a separate designer.
— SaaS platforms, MVPs, full builds: idea to launch, on a timeline that's actually real.
𝗧𝗘𝗖𝗛 𝗔𝗥𝗦𝗘𝗡𝗔𝗟:
Mobile — React Native, Expo, Swift, Kotlin
Frontend — React, Next.js, Angular, JavaScript, TypeScript
Backend — Node.js, Express, NestJS, Laravel, PHP, Python
AI & Automation — OpenAI, Claude, LangChain, RAG systems, LLM, Chatbots
Databases — MongoDB, Firebase, Supabase, MySQL, PostgreSQL
Cloud & DevOps — AWS, Docker, CI/CD, Serverless
Integrations — Stripe, PayPal, Twilio, Google Maps, Firebase Auth
𝗪𝗛𝗘𝗥𝗘 𝗜'𝗩𝗘 𝗕𝗨𝗜𝗟𝗧 𝗧𝗛𝗜𝗦 𝗕𝗘𝗙𝗢𝗥𝗘:
Banking & FinTech
— full banking apps, end to end
— Secure signup, OTP and biometric login
— Payments: cards, bank transfers, wallets, Stripe, PayPal
— KYC and identity verification, real-time transaction history
— Bank-grade encryption, 2FA, fraud detection
— One FinTech product I built scaled past 1M users
E-Commerce & Marketplaces
— stores and multi-vendor platforms
— Product catalogs, search, filters, cart, secure checkout
— Multi-vendor dashboards and seller payouts
— Stripe, PayPal, cash on delivery
— Order tracking, reviews, loyalty programs
On-Demand & Booking
— real-time service and booking apps
— Live scheduling and availability calendars
— Real-time GPS tracking and route optimization
— Separate customer and provider apps
— In-app payments, automated payouts, live chat
Healthcare & Telemedicine
— secure, compliant health apps
— Patient profiles, appointment and doctor scheduling
— Video consultations, secure messaging, prescriptions, health tracking
EdTech & E-Learning
— course and live-learning platforms
— Role-based signup, course catalogs, video lessons, live classes
— Quizzes, assignments, certificates, subscriptions
Social & Dating
— community and matching apps
— Profile verification, smart matching, discovery feeds
— Real-time chat and video, moderation, premium tiers
AI-Powered Apps
— smart products built on modern AI
— ChatGPT, Claude, OpenAI API integration
— RAG systems, document processing, AI chatbots
— AI-driven recommendations, smart search, automation
𝐑𝐞𝐥𝐞𝐯𝐚𝐧𝐭 𝐒𝐤𝐢𝐥𝐥𝐬 & 𝐊𝐞𝐲𝐰𝐨𝐫𝐝𝐬:
React Native | React Native Developer | React Native App Developer | React Native Expert | React Native Engineer | React Native CLI | React Native Expo | React Native App Development | React Native Cross Platform Developer | React Native iOS Developer | React Native Android Developer | Cross Platform App Developer | Mobile App Developer (iOS & Android) | Hybrid Mobile App Developer | React Native Application Development | React Native UI/UX Developer | React Native Freelancer | React.js Developer | Next.js Developer | Frontend Developer | UI Developer | TypeScript Developer | JavaScript Developer | Responsive Web App Developer | Single Page Application (SPA) Developer
I don't take every project — only the ones I can commit to fully and deliver past what was promised. If you're building an MVP, or bolting AI onto something that already works, tell me the idea in one line. You'll get a real plan back, not a sales pitch.
