⚡ 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. The code was clean, well structured, and the project was delivered on time."
