Paritosh S.

I build production-ready AI-powered web and mobile applications that combine modern full-stack development with AI agents, automation, LLMs, RAG, and intelligent workflows. I work across React, Next.js, Node.js, Python, React Native, Flutter, and modern AI technologies, helping startups, enterprises, and growing businesses turn ideas, existing products, and manual workflows into scalable digital products. Whether you need an AI SaaS platform, web application, mobile app, AI agent, business automation system, customer-facing assistant, or an existing product enhanced with AI, I can handle the development from architecture through production. What I Build AI Agents & Intelligent Applications • AI agents and agentic workflows • AI copilots for employees and customers • Tool-calling and function-calling agents • Multi-agent workflows • AI assistants connected to business systems • LLM-powered applications • AI memory and context management • Human-in-the-loop workflows • AI-powered search and recommendations • AI-driven decision-support applications AI Automation & Business Workflows • End-to-end workflow automation • AI-powered customer support • Sales and lead qualification automation • Appointment scheduling and follow-ups • Email, SMS and WhatsApp automation • Document processing and data extraction • CRM and ERP automation • API and webhook-based integrations • n8n, Make, Zapier and custom automation • Human approval, escalation and exception workflows AI-Powered Web Applications • SaaS platforms • Enterprise web applications • AI dashboards and admin portals • Customer portals and marketplaces • Internal business applications • Real-time web applications • API-driven applications • Subscription and billing platforms AI-Powered Mobile Applications • iOS and Android applications • React Native applications • Flutter applications • AI assistants inside mobile apps • Voice-enabled mobile experiences • Real-time applications • Push notifications and deep linking • Payments and subscriptions • Maps, GPS and location-based features • Bluetooth and IoT integrations • App Store and Google Play deployment LLM, RAG & Enterprise AI I build AI applications that work with your data, documents, business rules and internal knowledge rather than simply generating generic responses. • Retrieval-Augmented Generation (RAG) • Enterprise knowledge assistants • Document Q&A • Semantic and hybrid search • Vector databases and embeddings • AI document intelligence • Source-grounded responses • Knowledge bases and enterprise search • AI memory and context management • Access-controlled retrieval Voice AI & Conversational Applications I also build voice-enabled AI experiences for web, mobile and business workflows: • AI voice agents • AI receptionists • Inbound and outbound calling • Voice-based customer support • Lead qualification • Appointment booking • Call summaries and data extraction • CRM updates after calls • Human transfer and escalation AI SaaS & Full-Stack Architecture For AI startups and businesses building their own products, I can work across the complete application stack: • Multi-tenant SaaS • Organization-level data isolation • RBAC and authentication • AI usage and cost tracking • Subscription and billing • Secure APIs • Admin dashboards • Cloud infrastructure • Background jobs and queues • Real-time communication • Monitoring and logging From Idea or POC to Production - I don't approach AI projects as simply connecting an LLM to a UI. A production AI product needs the right combination of: Business workflow + UX + application architecture + AI + data + integrations + security + monitoring My approach typically includes: 1. Understanding the business and user workflow 2. Defining the product and technical architecture 3. Identifying the right AI/automation opportunities 4. Building a focused MVP or proof of concept 5. Integrating APIs, databases and business systems 6. Testing AI behavior, workflows and edge cases 7. Deploying to production 8. Monitoring, optimizing and supporting the product I have worked across: • Healthcare & Wellness • FinTech • Real Estate • Logistics & Supply Chain • Education • E-commerce • Manufacturing • Insurance • Sales & Marketing • Enterprise Operations Why Clients Work With Me ✓ Top Rated Plus Upwork developer ✓ 100% Job Success Score ✓ 1,200+ Upwork hours delivered ✓ Full-stack + AI + mobile development capabilities ✓ Experience building production AI applications and SaaS platforms ✓ Strong API, CRM/ERP and third-party integration experience ✓ Experience with AI agents, RAG, automation and voice AI ✓ Comfortable working with existing codebases and architectures ✓ Focus on scalable, secure and maintainable solutions ✓ Clear communication and practical technical decision-making If you have a PRD, Figma design, existing application, API, database, AI prototype or simply a business idea, I can help turn it into a working product.
