I am a full stack developer and AI integration specialist building production-grade SaaS apps, chatbots, voice AI systems, and custom AI workflows on Node.js, React, AWS, Claude and OpenAI APIs. Most AI tools like Lovable, Replit, Bolt, Claude, Cursor get you 70% there. The last 30% is where projects die. I take over where those tools hit their limits, clean up the code, and ship a product that actually works in production. Here is what I build: ⚙️ Full Stack SaaS Applications End-to-end SaaS products on Node.js and AWS. Authentication, billing, dashboards, APIs, and everything between idea and a live product. 🔧 Vibe Code Rescue Your Lovable, Bolt, Cursor, or v0 build works as a demo but breaks in production. I take over, clean it up, and ship it properly. 🎙️ Voice AI Systems AI phone systems handling real customer interactions. Automated ordering, booking, and support that works without human intervention. 🤖 AI Chatbots Context-aware chatbots for SaaS, healthcare, and hospitality built with OpenAI, Claude, and Gemini. Production-ready from day one. ⚡ AI Automation & Workflow Systems Custom pipelines connecting your AI tools, APIs, and business logic into systems that run without manual intervention. Who I work best with: 🚀 Founders with a SaaS or AI product idea who need one senior developer to own the full build without gaps or handoffs. 🔥 Founders who built with Lovable, Bolt, or Cursor and need a real engineer to take it from demo to production. 🧩 Product teams whose existing app needs AI added properly. Not a quick API call. A real AI layer built to scale. I manage a structured delivery process. One point of contact. Full accountability. Senior oversight on every line that ships. How I work: 🔍 Discovery before code I understand your product goal and business logic before touching architecture. Most projects fail because this gets skipped. 🏗️ Architecture before development Full technical architecture defined and agreed before a single line is written. No surprises mid-build. 🎯 Milestone-based delivery Working builds at each stage. You test throughout, not just at the end. 🚢 Deployment included The job is not done until your product is live and working in production. For rescue projects: I start with a full codebase audit, tell you honestly what can be saved and what needs rebuilding, then execute clean. Recent work: ⚡ DocChief: Built the AI extraction layer and backend for a legal document intelligence platform now processing $250M+ in deal flow with 80% reduction in admin overhead. 🏨 HotelsByDay: Built the React Native mobile app for a day-use hotel marketplace with 7 consecutive quarters of growth. 📄 DocumentPro: Built the frontend for an AI document processing platform automating hundreds of invoices monthly across 50+ languages. 🔒 Active: AI mental health chatbot platform, 11+ months. Voice AI restaurant phone system, 6+ months. Both under NDA. $100K+ earned. 4,200+ hours. 100% Job Success. Top Rated. Clients stay for 6 to 11 months because the work actually delivers. Whether you are starting from scratch, stuck mid-build, or rescuing something an AI tool left unfinished, I am happy to take a look. Share the details and I will tell you honestly what is possible and how long it will take.

40+ apps live across healthcare, logistics, fintech, and AI including a 4.8-star iOS app currently ranked on the App Store. When founders need someone who can own the build end-to-end and not disappear mid-project, they come back to me. Three of my last five clients have. Here's what that looks like in practice: → Built myTMJ: an AI-powered healthcare app (SwiftUI, clean architecture, real-time symptom tracking). Live. 4.8 stars. Still running. → Built Bijlink & TryGrunt: two-sided logistics marketplaces handling driver matching, live tracking, and complex backend logic. → Built FoundersMine: an enterprise SaaS platform with role-based access, integrations, and a dashboard non-technical founders can actually use. → Built ConvertMatrix: a marketing AI tool that turned raw campaign data into automated insights. What I'm actually good at: React Native apps that don't feel cross-platform. iOS apps in SwiftUI built to scale. Django + React backends that don't fall over. AI features that are genuinely useful, not just bolted on. I work best with funded startups and technical co-founders who have a clear vision and need a senior developer they don't have to babysit. I'll ask hard questions early, flag problems before they're expensive, and ship something you're proud to put in front of investors. If you're looking for the cheapest option — I'm not it. If you're looking for the right one — let's talk. ──────────────────────────────── Tech: React Native · SwiftUI · Django · TypeScript · AWS · LangChain · RTK Query · SwiftData · REST APIs · App Store Deployment ──────────────────────────────── 01 - FinTech: Payment gateways, digital wallets 02 - Healthcare: Telemedicine, patient portals, health tracking, HIPAA compliance 03 - E-Commerce: Shopping apps, order tracking, payment processing, inventory management 04 - Social Media: Real-time chat, video calling, content sharing, user engagement 05 - On-Demand Services: Ride-sharing, food delivery, service marketplace apps 06 - Education: E-learning platforms, course management, video streaming 07 - Real Estate: Property listings, virtual tours, CRM integration Mobile App Developer | iOS Developer | Android Developer | Swift Developer | Generative AI | Flutter Developer | React Native Developer | Cross-Platform Development | Native App Development | Mobile Application Development | App Development | Mobile Engineer | LangChain | Android Engineer | Full Stack Mobile Developer | FinTech Developer | Healthcare App Developer | Mobile UI/UX | App Store Optimization | Mobile Security | Firebase Developer | Mobile API Integration | Payment Integration | Push Notifications | AI Engineer | CI/CD Mobile | TestFlight | App Store Submission | Play Store Publishing | Mobile Performance Optimization | Startup MVP Development | Enterprise Mobile Solutions | HIPAA Compliant Apps

🚀 I build production AI apps — LLM agents, RAG systems, and AI-native products — that actually ship and scale, not demos that break in front of your users. 👋 Hi, I'm Adarsh — an AI-focused Full-Stack Developer and former CTO with 12+ years building software.

I ship the whole thing, not just the prompt. ✅ Full-Stack & Mobile Foundation React, Next.js, Node.js, Laravel on the backend; React Native, Flutter, Swift, Kotlin on mobile. Clean, scalable architecture — no spaghetti, no tech debt. ✅ Fractional CTO / Technical Strategy For founders who need more than a coder: architecture decisions, code audits, and a roadmap that gets you to investor-ready. --- 🧠 Tech Stack AI: OpenAI, Anthropic Claude, LangChain, RAG, vector DBs (Pinecone, pgvector), embeddings, fine-tuning Backend: Node.js, Laravel, GraphQL, AWS, Firebase Frontend: React, Next.js, Vue.js Mobile: React Native, Flutter, Swift, Kotlin --- ⭐ "Adarsh has become an essential part of our team — his attention to detail and constant communication make working with him a breeze." — Ana Streczyn, Holy Emojis ⭐ "We depend on Adarsh daily, and his work is consistently outstanding.
