โšก Senior Full Stack Developer | 9 Years | MERN Stack, Next.js, React Native, Node.js ๐ŸŽฏ Real Products, Real Users, SaaS Platforms, MVPs, Websites & Mobile Apps ๐Ÿ’Ž React, Node.js, MongoDB, PostgreSQL, TypeScript, Stripe, OpenAI, AWS, Docker ๐Ÿ” 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. ๐Ÿ“– 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. ๐Ÿ› ๏ธ 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. ๐Ÿ’ฌ WHAT A CLIENT TOLD ME "He understood the requirements quickly, suggested practical improvements where needed, and handled both the frontend and backend efficiently. The code was clean, well structured, and the project was delivered on time." โ€” Upwork Client โญโญโญโญโญ โœ… WHAT I BRING โœ”๏ธ SaaS Platform & Startup MVP Development โœ”๏ธ Websites with React & Next.js โœ”๏ธ Backends with Node.js, Express, MongoDB & PostgreSQL โœ”๏ธ React Native Apps for iOS & Android โœ”๏ธ Compliance-First Builds (HIPAA, HITRUST, PCI, PIPEDA) โœ”๏ธ REST & GraphQL API Development โœ”๏ธ AI Features with the OpenAI API โœ”๏ธ Role-Based Access & Data Security โœ”๏ธ Stripe Subscription Billing โœ”๏ธ Deployment on AWS, Vercel & Docker ๐ŸŒ FIELDS I'VE WORKED IN ๐Ÿฉบ Healthcare & Mental Health ยท ๐ŸŽ“ Education & School Management ยท ๐Ÿ’ณ Fintech Wallets & Escrow ยท ๐ŸŽง Voice, Coaching & Reading Apps ยท ๐Ÿคฒ Non-Profit & Crisis Support ยท ๐Ÿ“ Content Publishing ยท ๐Ÿ–ผ๏ธ Arts Organisations ยท ๐Ÿ“ˆ SaaS & Subscription Platforms ๐Ÿงฐ TECH I WORK WITH Frontend: React, Next.js, TypeScript, Tailwind CSS Backend: Node.js, Express, REST APIs, GraphQL Database: MongoDB, PostgreSQL, Firebase Mobile: React Native, Expo AI: OpenAI API ยท DevOps: Docker, AWS, Vercel ยท Payments: Stripe ๐Ÿ“ฌ WANT TO TALK ABOUT YOUR PROJECT?

I build and ship production software โ€” not prototypes. As a founder, I run multiple live SaaS products serving 110,000+ users, and as a Lead Software Engineer I've spent 4+ years turning complex business needs into fast, scalable systems. What that means for you: I've been on the client side of my own products. I think about uptime, server costs, data integrity, and user retention โ€” because my own revenue depends on them. ๐Ÿš€ Products I've Built and Operate: ---------------------------------------- ๐Ÿ“ฑ Mezgebe Tselot โ€” native Android app with 110,000+ active users, built from scratch (Java/Kotlin, Firebase App Checkโ€“secured API) ๐Ÿ”— MotifQR โ€” a dynamic QR code SaaS with branded designs, scan analytics, smart pages, and subscription billing. Built end-to-end with Next.js, Node.js, and Postgress โ€” live in production (link in Portfolio) ๐Ÿ“Š AffCollect โ€” multi-tenant affiliate earnings SaaS aggregating 50+ networks, with Stripe subscription billing, two-way Xero invoicing sync, and Kubernetes deployment with KEDA autoscaling. Clustered Node.js scraping boosted throughput by 400% ๐Ÿ’ผ What I Do for Clients: ---------------------------------------- ๐Ÿ’ป Full-Stack Development (MERN + Next.js): from concept to deployment, TypeScript throughout ๐Ÿค– AI & LLM Integration: production-grade LLM features โ€” structured outputs, tool calling, RAG over your documents, and agent workflows. I use these daily in my own products โšก High-Performance Backends: scaled real-time WebSocket apps with Redis Pub/Sub; MongoDB aggregation optimization. I'm a MongoDB Certified Associate Data Modeler with the Advanced Schema Design badge ๐Ÿ“ฑ Mobile Development: React Native cross-platform + native Android (Java/Kotlin). Shipped IoT/Bluetooth (BLUFI) apps for Upwork clients โ€” all rated 5 stars ๐Ÿ”ง DevOps: Docker, Kubernetes (KEDA autoscaling), GitLab CI/CD, VPS deployment (GCP, Digiral Ocean, Hetzner), PostgreSQL & MongoDB migrations ๐Ÿ› ๏ธ Tech Stack: ---------------------------------------- โœจ Backend: Node.js, Express.js, TypeScript, WebSockets, Redis, Vercel AI SDK โœจ Frontend: React.js, Next.js, Redux, Tailwind CSS โœจ Mobile: React Native, Android, Java, Kotlin โœจ Databases: MongoDB, PostgreSQL, MySQL, Firebase โœจ DevOps & Tools: Docker, Kubernetes, GitLab CI/CD, Puppeteer, Stripe, REST APIs If you want a developer who has actually operated software at scale โ€” not just written it โ€” let's talk.
