Shams T.

Senior Engineer | Node.js, React, NestJS | Microservices at Scale

A restaurant chain came to me needing a POS system that wouldn't crash during a Friday night rush. A national park system needed to handle 50,000 bookings a year without a single ticket getting lost. A platform needed to scale to 15,000 users without the backend falling over. I built all three, and they're still running today. That's the kind of senior developer I am: I care less about impressive demos and more about what happens after launch, when real traffic and real users start testing your app for you. Over the past 5+ years, I've worked across Node.js, React, NestJS, Next.js, and Laravel, architecting everything from microservices-based backends to real-time, distributed systems. That range means I can usually adapt to whatever stack and architecture a project actually needs, instead of forcing my favorite tools on it. ═══════════════════════ PROJECTS ═══════════════════════ ▸ Balkanza | Node.js, React.js, PostgreSQL A platform I built and helped scale to 15,000+ active users. Handled the full-stack architecture, from database design to the React front-end, keeping performance steady as the user base grew. ▸ MoltoVino POS | Node.js, React, MongoDB, Firebase A point-of-sale system for a multi-location restaurant chain. Handles real-time inventory, order management, and instant staff notifications, so orders don't get lost during a busy dinner rush. ▸ Project Central (Enterprise Inventory System) | Laravel, Docker, MySQL, JavaScript A multi-warehouse inventory platform with real-time tracking and analytics, built to cut down on wasted stock and help teams make faster supply chain decisions. ▸ SaaS CRM for Real Estate | Node.js, Express, MongoDB, React Designed the backend for a subscription-based CRM with Stripe payments and Google API integrations, so agents can manage clients and listings in one place instead of a dozen spreadsheets. ▸ Parks & Wildlife Ticketing Platform | NestJS, TypeScript, AWS A booking system for national parks handling 50,000+ bookings a year, with QR code check-ins and a live analytics dashboard. Cut booking time by 60% by simplifying the process. ═══════════════════════ TECH I WORK WITH ═══════════════════════ → Back-end: Node.js, NestJS, Python/Django, FastAPI, PHP/Laravel → Architecture: Microservices, Distributed Systems, RESTful APIs, WebSocket → Front-end: React, Angular, Next.js, TypeScript, Tailwind CSS → Databases: MongoDB, MySQL, PostgreSQL, Firebase, Redis → Cloud/DevOps: AWS (EC2, S3, RDS), Docker, CI/CD → Integrations: Stripe, Google APIs, Salesforce ═══════════════════════ WHY WORK WITH ME ═══════════════════════ I handle projects end to end, from planning through deployment, and I'm upfront if something in the scope or timeline doesn't make sense, rather than letting you find out later. I also have real experience with SaaS-specific needs like multi-tenancy and subscription billing, not just generic CRUD apps. If you need someone who can take a project from an idea to something that actually works in production, I'd be glad to help. Feel free to reach out and tell me what you're working on.
