Since 2016, I have been on Upwork building and scaling web, mobile, and AI-powered applications. I have helped 60+ clients globally, maintained a 100% Job Success Score, and delivered 11,000+ hours of work, turning ideas into production-ready products. I have worked in teams of 50-100 members and led small to mid-sized teams across multiple projects to deliver complex systems end-to-end. I have successfully delivered 50+ web projects and 30+ mobile applications, all built and deployed in production environments, including handling app store submissions, approvals, and rejections. 👉 What I Build 👈 I design and build scalable mobile and web platforms using React, Next.js, Node.js, Angular, Express, Capacitor, Ionic, React Native, and Python, extended with AI capabilities like chatbots, voice agents (Vapi, ElevenLabs), LLM integrations (OpenAI, Gemini, Claude), and advanced workflows using LangChain and LangGraph, including RAG pipelines, agentic systems, and intelligent automation. I consistently help clients turn raw ideas, prototypes, and proofs of concept into production-ready MVPs using AI-assisted development tools like Claude Code, Cursor, GitHub Copilot and modern rapid-building approaches using vibe coding tools like Lovable and Replit for faster iteration and validation. My goal with every client is complete satisfaction, achieved through technical excellence, responsive communication, and proactive suggestions. 👉 How I Work 👈 I have worked extensively on cross-platform mobile applications using Capacitor, Ionic, React, Angular, and Vue, building and scaling production apps with a strong focus on performance, maintainability, and architecture. I have modernized legacy codebases, upgraded Angular and Ionic applications, and successfully migrated Cordova projects to Capacitor for better stability and long-term scalability. On the backend, I build stable and scalable systems using Node.js and Python, with experience across Firebase, Supabase, AWS, and GCP. I have handled real-time architectures, large datasets, and optimized infrastructure to improve performance and reduce operational costs, especially in Firebase-heavy applications. Most of the work I deliver today involves complete product systems where mobile apps, web platforms, and admin dashboards are connected through a shared backend, including SaaS platforms, subscription-based products, and data-driven applications that require reliability and scalability from day one. 👉 AI Development & Integrations 👈 My focus is on making AI genuinely useful inside products, not just adding it as a feature. I design AI workflows that fit into real user journeys, improving how users search and interact with data, automating repetitive tasks, and building systems that reason and respond intelligently. This includes structuring RAG pipelines, designing agent workflows, and implementing retrieval systems that work reliably at scale, with proper handling of edge cases, performance, and cost optimization. AI that improves the product experience and reduces manual effort. That is the standard I hold myself to. 👉 Core Skills & Technologies 👈 *Frontend & Mobile Development* ✔ Angular, React, Next.js ✔ React Native (Cross-platform mobile apps) ✔ Capacitor, Ionic (Modern hybrid app development) *Backend & APIs* ✔ Node.js (Express, NestJS), TypeScript, JavaScript ✔ Python (FastAPI, Django) ✔ REST APIs, GraphQL *Databases & Cloud* ✔ MongoDB, MySQL, PostgreSQL ✔ Firebase (Auth, Firestore, Realtime DB, Functions, FCM) ✔ Supabase (Auth, Realtime, Storage, Edge Functions) ✔ AWS, GCP, Azure *DevOps & Deployment* ✔ CI/CD pipelines (GitHub Actions, Bitbucket, GitLab CI) ✔ GitHub (version control, workflows, collaboration) ✔ Docker (containerization) ✔ Cloud deployments, environment management, monitoring *AI Development* ✔ OpenAI, Gemini, Claude integrations ✔ LangChain, LangGraph (AI workflows & agents) ✔ RAG pipelines, vector search, semantic retrieval ✔ Voice AI (Vapi, ElevenLabs) *AI Tools & Development Workflow* ✔ Cursor, GitHub Copilot, Claude Code ✔ Rapid MVP development using AI-assisted coding ✔ Code review, validation, and optimization of AI-generated code ✔ Rapid prototyping approaches (Lovable, Bolt, Replit) for faster iteration *Mobile Platforms* ✔ iOS & Android deployment, optimization, and app store management 👉 Why Clients Work With Me 👈 - I don’t just write code, I build products that are meant to scale and survive real users - Strong ownership from idea → MVP → production → scaling - Balanced expertise across mobile, web, backend, and AI, so you don’t need multiple developers - Fast execution using AI-assisted development, without compromising code quality - Experience handling real-world issues like performance bottlenecks, Firebase & Supabase, and app store rejections If you have an idea, MVP, or scaling issue? Send me the details. I will break down the approach, timeline, and next steps clearly. Best, Sandip
