🏆8+ years of experience, 🏆47+ shipped projects, 🏆SaaS that generated over $1.000.000+
🔥 I'm a Full Stack Developer React Node who helps startups launch profitable SaaS products in 4 weeks instead of months. 🏆With 8+ years of experience and 🏆47+ shipped projects generating $1M+🏆 I combine fast execution with beautiful design - so your product scales from MVP to revenue without technical debt.
🔎Why: Most teams choose between speed or quality. I deliver both using MERN Stack architecture that handles growth. Your customers get intuitive experiences. Your business gets reliable, scalable code. Your team stays sane.
💼What you get: Production-ready SaaS platforms, real-time dashboards, payment integrations, and zero excuses on delivery.
━━━━━━━━━━━━━━━━━━━━━
WHY CHOOSE commonsaltx:
I'm a Full Stack Developer React Node with 8+ years shipping products that generate revenue, not just demos. As both a UX Designer and Front End Developer React I understand that beautiful code means nothing without beautiful user experiences.
Most projects I lead use a MERN stack foundation: React for the interface, Node.js for the backend, MongoDB or PostgreSQL for data, and modern deployment on Vercel or AWS. This architecture scales from MVP to millions of users without rewriting.
As a Front End Developer React I build fast, responsive dashboards and portals. As a Back End Developer Node.js I design Node.js API that handle real-time features, payments, authentication, and integrations. Together as a Full Stack Developer this is how products ship.
━━━━━━━━━━━━━━━━━━━━━
As a Full Stack Developer React Node combining Front End Developer React expertise with robust backend systems. I specialize in React Next.js Supabase implementations and MERN stack architectures, building scalable solutions using React Node Express, GraphQL, PostgreSQL, and MongoDB. As a UX designer I ensure beautiful interfaces pair with powerful backends. I'm also familiar with Laravel Vue and Ruby on Rails for legacy integrations when needed.
━━━━━━━━━━━━━━━━━━━━━
WHAT I DELIVER
✅ SaaS Platforms – Admin dashboards, role-based access, analytics, real-time sync using React Node foundations.
✅ Startup MVPs – From wireframe to launch in 3–4 weeks, built as a full stack developer with React, Node, and database layer.
✅ Web Apps – Marketing sites, portals, e-commerce flows with Next.js, Supabase, payment integrations (Stripe, PayPal).
✅ Real-Time Features – Chat, notifications, live updates, collaboration using WebSockets and server-sent events via Node.js backend.
✅ API Development – RESTful and GraphQL endpoints, webhook handling, OAuth/JWT security, third-party integrations.
✅ Database Architecture – PostgreSQL, MongoDB, Firebase design optimized for scale and maintainability.
━━━━━━━━━━━━━━━━━━━━━
HOW I WORK
As a Full Stack Developer, I think like a product engineer: clarify goals, design core flows, cut scope where needed, ship a working MVP that users can test in weeks, then iterate with real feedback instead of endless refactors.
Before writing code, as a UX Designer I spend time on wireframes, user journeys, accessibility, and design systems. This prevents rework and ensures the UI feels intuitive even when the logic is complex.
On the backend side, as a Node.js developer I build REST and GraphQL APIs, handle authentication, manage databases, and integrate third-party services. Using a MERN stack approach keeps systems simple enough to iterate fast yet structured for long-term maintenance.
━━━━━━━━━━━━━━━━━━━━━
