Senior Full Stack Mobile & AI Developer | Flutter, React Native, SwiftUI, Kotlin | SaaS, AI Agents, Scalable Systems Overview / About Me I help startups and businesses build scalable mobile apps, SaaS platforms, and AI-powered systems designed for real users, real scale, and real revenue. With 7+ years of experience and 80+ production apps delivered, I specialize in building full product ecosystems from UI UX and system architecture to backend APIs, cloud infrastructure, and AI integrations. My core expertise lies in combining mobile engineering with modern AI systems including RAG pipelines, AI agents, automation workflows, and LLM based applications using OpenAI, Claude, Llama, Whisper, and LangChain. I work across Flutter, React Native, SwiftUI, and Kotlin for mobile apps, and Node.js, Python, FastAPI, and Django for backend systems. All solutions are deployed on AWS with scalable DevOps practices using Docker, CI CD, and Kubernetes where needed. I don’t just build apps I build complete product systems that are scalable, maintainable, and ready for growth. What I Can Build for You Cross platform mobile apps Flutter, React Native Native apps SwiftUI, Kotlin SaaS platforms and multi tenant systems AI powered applications chatbots agents copilots RAG based knowledge systems and automation tools Marketplaces and booking platforms CRM and enterprise dashboards Real time apps chat tracking notifications Backend APIs and microservices Node.js Python Cloud deployment and DevOps AWS Docker CI CD AI Expertise OpenAI GPT integrations Claude Llama based systems RAG architecture retrieval augmented generation AI automation workflows Voice AI Whisper ElevenLabs LangChain based applications Custom AI assistants and copilots Document intelligence systems Tech Stack Flutter React Native SwiftUI Kotlin React Next.js Node.js Python FastAPI Django PostgreSQL MongoDB Firebase Supabase AWS Docker Kubernetes CI CD OpenAI Claude Llama LangChain Whisper ElevenLabs Stripe Razorpay Twilio WebRTC Selected Projects AI Platforms Maiday AI Enterprise AI automation system Novlt.ai AI storytelling and content generation platform Joye.ai Workplace emotional intelligence platform Qreate AI hiring and resume intelligence system Marketplaces and Apps Wagkart Pet service marketplace Beauty Spot Booking and salon platform Loop Ride Share Real time ride hailing platform Go Test Rapide Healthcare booking system SaaS and Enterprise Systems ShipDistrict Logistics and shipping SaaS platform Enroltime Education and visa management system CRM systems HoneyBook like workflows Social and Streaming StreamRebels Live streaming and monetization platform Bizfluence Professional networking platform Jalebi Niche dating platform SALXN Video content platform Why Work With Me Full product ownership from idea to deployment Strong focus on scalable architecture not just MVPs Deep experience in AI SaaS and mobile ecosystems Clean production ready codebase Fast execution with reliable communication Long term maintenance and scaling support Availability MVP development SaaS product builds AI integration projects Mobile app development Backend architecture and scaling Ongoing product improvements Final Note If you're looking for someone who can take your idea from concept to design to development to deployment to scaling, I can help you build a production ready system that grows with your business

🚀 You're building an AI-powered product. You need someone who ships the whole thing — not just the AI layer. I'm a Senior Full Stack Engineer with 8+ years specialising in Full stack development & AI-integrated SaaS platforms. I've architected multi-tenant systems, wired LLMs into production backends, and shipped complete products — auth, database, billing, and AI pipeline — from scratch. Most "AI developers" can call an API. What they can't do is design the schema, enforce data isolation at the Postgres level, wire Stripe for usage-based billing, and deploy it all on a zero-downtime infrastructure. That's where I'm different. 🔹 AI Integration & LLM Engineering I build production-grade AI features — RAG pipelines, streaming chat interfaces, document intelligence, OpenAI and Anthropic API integration, vector search with pgvector and Pinecone. I focus on making AI reliable, cost-efficient, and actually useful in a real product. 🔹 Multi-Tenant SaaS Architecture Designed and shipped multi-tenant platforms with workspace-level data isolation, RLS policies enforced at the Postgres level, and Supabase backends that scale cleanly. I've built the kind of schema that doesn't fall apart at 10,000 users. 🔹 Full Stack Product Engineering Next.js, TypeScript, Node.js, NestJS, PostgreSQL, Supabase — I own the entire stack. Not just the frontend, not just the API. The whole product, built to hand off cleanly to your team. 🔹 Stripe & Billing Systems Usage-based billing, seat pricing, metered subscriptions, webhook-driven lifecycle management — wired directly to Supabase Edge Functions for reliability and auditability. Recent work: ✅ TryMyGuns — Lead Architect. Multi-role marketplace with full buyer/seller/admin data isolation, built and deployed in 4 weeks. If you're building an AI SaaS product and need an engineer who takes full ownership — let's talk.

I help Shopify store owners turn slow, underperforming stores into fast, high-converting ones. As a Top Rated Plus Shopify developer with 8+ years of experience, I focus on the two things that directly affect your revenue: site speed and conversion rate. I'm a Shopify developer and designer with 200+ completed projects, $100K+ earned, and a 100% job success score - and my work centers on: - Shopify speed optimization (Core Web Vitals, PageSpeed, theme/code cleanup) - Conversion rate optimization (CRO) - layout, checkout flow, product pages - Custom theme development and design (Shopify 2.0, Liquid) - Store redesigns and platform migrations (including from WooCommerce) - App audits and integrations that don't slow your store down Speed and conversion go together: a one-second delay can cost conversions, and most stores are carrying bloated apps and unoptimized themes that quietly drag both down. I find what's slowing your store, fix it at the code level, and structure your pages so more visitors actually buy. One recent project involved rebuilding a store under a tight deadline - migrating 500+ products from WooCommerce to Shopify with custom theme work, launched fast without losing data or design quality. I'm Shopify Partner Academy certified with a Master's in Computer Science, and clients consistently highlight clear communication, attention to detail, and reliability in their feedback. If your Shopify store loads slowly, converts poorly, or just needs to perform better, send me your store URL and a note about what you're seeing - I'll tell you where the biggest wins are.
