Nikunj G.
AI SaaS Mobile & Web App Developer | Flutter | MERN | iOS | Android
I build complete digital systems not just apps. If you need someone who can handle mobile apps, web platforms, backend architecture, and AI-driven automations together, I can take ownership of the full stack and deliver a working product end-to-end. With 12+ years of experience, I’ve worked across startups and production-scale systems where stability, scalability, and speed matter more than just writing code. Core Expertise: 1. Mobile Development + Flutter, React Native, iOS (Swift), Android (Kotlin/Java) + Cross-platform apps with smooth UI, performance optimization, and production-ready builds 2. Web Development (Full Stack) + MERN Stack (MongoDB, Express, React, Node.js) + Next.js-based apps, dashboards, admin panels, SaaS platforms 3. AI Integrations & Automation + OpenAI / GPT-based features + AI-powered SaaS workflows + Chatbots, assistants, and intelligent automation systems 4. Automation & Workflows + n8n automation pipelines + API orchestration + Business process automation (CRM, notifications, integrations) 5. Backend & Systems + REST APIs, authentication systems, role-based access + Real-time systems (WebSockets, Firebase) + Database architecture (MongoDB, MySQL, Supabase, Firebase) 6. Payments & Monetization + Stripe, RevenueCat, PayPal, in-app purchases + Subscription systems and usage-based billing What I Build: + AI SaaS platforms (mobile + web dashboards) + Automation systems using n8n and APIs + Subscription-based products + Real-time applications (chat, tracking, notifications) + Admin panels, CMS, CRM tools + MVPs to full-scale production systems How I Work: + I understand complete system flow, not just isolated features + I focus on clean architecture and long-term scalability + I can take a project from idea to MVP to production to scaling + I minimize dependency you don’t need to manage multiple developers
