Full Stack Developer | MERN SaaS | Multi-Tenant & RBAC
𝐌𝐄𝐑𝐍 𝐒𝐭𝐚𝐜𝐤 𝐒𝐚𝐚𝐒 𝐃𝐞𝐯𝐞𝐥𝐨𝐩𝐞𝐫 | 𝟕+ 𝐘𝐞𝐚𝐫𝐬 | 𝟑𝟎+ 𝐀𝐩𝐩𝐬 𝐒𝐡𝐢𝐩𝐩𝐞𝐝 I've shipped 30+ MERN SaaS platforms, including multi-tenant apps serving 10,000+ users with zero downtime. You get production-grade architecture from day one, not a demo that collapses under real load. Most developers make features work. I ask the questions they skip: • What happens at 10x users? • Who maintains this in year two? • Where will this break first? The answers shape how I architect from day one. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ 𝐖𝐇𝐀𝐓 𝐈 𝐁𝐔𝐈𝐋𝐃 ✅ MERN SaaS Platforms — React, Node.js, Express, MongoDB ✅ Multi-Tenant Business Applications — CRM, ERP, LMS, Project Management tools ✅ Role-Based Dashboards — admin, manager, user access control (RBAC) ✅ Subscription Billing — Stripe integration, usage-based pricing, invoicing ✅ AI & LLM Integration — OpenAI API, chatbots, AI-powered workflows ✅ API & Third-Party Integrations — Stripe, CRM connectors, REST APIs ✅ Mobile Apps — React Native & Flutter (iOS + Android), MVP to app store ✅ Backend Architecture — Node.js, Express, PostgreSQL, Firebase, GraphQL ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ 𝐖𝐇𝐘 𝐂𝐋𝐈𝐄𝐍𝐓𝐒 𝐑𝐄𝐇𝐈𝐑𝐄 𝐌𝐄 • Delivered multi-tenant MERN SaaS platforms serving 10,000+ users with zero downtime • Improved backend performance by 30–40% through optimization and caching • Launched high-performance platforms reaching 15,000+ users • Shipped scalable MVPs in 6 weeks • Implemented CI/CD pipelines (AWS & Firebase) for zero-downtime deployments ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ 𝐌𝐘 𝐏𝐑𝐎𝐂𝐄𝐒𝐒 You bring the idea or requirements.
