For 7+ years I've built and scaled the backends behind web products: APIs, queue-based systems, and cloud architecture that stay fast and reliable when traffic spikes. If your platform is slowing down, your API needs building, or you're scaling and things are starting to break, that's exactly what I fix. I work end to end, but my real strength is the hard part of the stack, the part that has to hold up when you get busy. ✅ Backend & Full-Stack Development: Laravel, Symfony, Node.js, REST/GraphQL APIs, multi-tenant SaaS, job queues, ACL, CI/CD ✅ Cloud & DevOps: AWS (EC2, S3, Lambda, SQS, RDS, EKS), Docker, Kubernetes, Nginx, Supervisor, GitHub Actions, scalable deployments ✅ Performance & Scale: Redis caching, database indexing & query optimization, async/queue architectures, load handling for high-traffic systems ✅ Third-Party Integrations: Stripe, Stripe Connect, Twilio, Firebase, Xero, Google APIs, and more ✅ Frontend & Admin Panels: Vue.js, Tailwind, Bootstrap, real-time dashboards, notifications, role-based access ✅ AI Integration (where it fits): OpenAI / GPT integration into real product workflows, such as translation and content automation I've built and managed full SaaS platforms from the ground up: user portals, admin panels, real-time tracking, automated workflows, all built for performance, stability, and scale. I communicate clearly, flag risks early, and don't go quiet mid-project. 📬 Tell me what you're working on and I'll tell you honestly whether I'm the right fit. Message me to get started.
