Gaurav D.

I'm a Senior Full Stack Developer and Technical Lead with 8+ years of experience building SaaS platforms, enterprise applications, AI-powered solutions, business automation systems, and cloud-based applications. I help startups and growing businesses turn ideas into production-ready software—from planning and system architecture to development, AI integration, deployment, and ongoing maintenance. My expertise combines full-stack engineering with Generative AI, LLM integrations, AI agents, and workflow automation. I build AI-powered applications, integrate intelligent features into existing products, and automate business processes using modern AI models and tools. I also work with AI-assisted and prompt-driven development tools to accelerate application development, prototype interfaces, and turn ideas into functional software while maintaining code quality and scalability. I don't just focus on writing code. I focus on understanding your business requirements, choosing the right technology, and delivering reliable solutions that create long-term value. 🤖 Generative AI, AI Engineering & Automation - Generative AI applications using OpenAI, GPT, Claude, and Gemini - LLM API integrations and AI-powered application development - AI-powered chatbots and conversational assistants - AI agents, tool calling, function calling, and agentic workflows - Retrieval-Augmented Generation (RAG) and knowledge-based Q&A systems - LangChain, embeddings, and semantic search - Model Context Protocol (MCP) integrations - Prompt engineering and structured AI outputs - AI-powered email analysis, response drafting, and business workflows - n8n workflow automation with AI models, APIs, and webhooks - Prompt-driven UI and application prototyping - AI-assisted development using Cursor, Claude Code, Windsurf, and other modern coding tools I can help you build a Generative AI application from scratch, integrate LLM capabilities into an existing product, connect AI models with business data and external tools, or automate repetitive workflows using n8n and APIs. 💻 Full Stack Development Frontend: React.js, Next.js, Angular, Vue.js, Nuxt.js, TypeScript, JavaScript, Tailwind CSS, shadcn/ui, Material UI, Bootstrap Backend: Node.js, Express.js, NestJS, GraphQL, PHP, Laravel, CodeIgniter, CakePHP, Python Databases: PostgreSQL, MongoDB, MySQL, Firebase, DynamoDB, MSSQL Mobile: Flutter, React Native ☁️ Cloud, DevOps & Infrastructure - AWS, Microsoft Azure, and Google Cloud Platform - Linux server administration and deployment - Docker, Kubernetes, and CI/CD pipelines - Nginx, PM2, and production application hosting - GitHub Actions and Jenkins - REST APIs, webhooks, and third-party integrations - Database optimization, caching, and background processing - SSL/TLS configuration, security, and deployment automation 🔌 Integrations & Connected Systems - Stripe, PayPal, Twilio, and SendGrid - Google APIs and third-party SaaS integrations - IoT devices, GPS tracking, and telematics platforms - MQTT messaging and device communication - Authentication, authorization, and role-based access control - Payment gateways, hardware integrations, and data synchronization 🏗️ Products & Systems I Build - SaaS platforms and subscription-based products - CRM, ERP, and business management systems - Generative AI and LLM-powered applications - AI agents, chatbots, and knowledge retrieval systems - Business workflow automation and internal productivity tools - Transportation, logistics, and dispatch management platforms - Inventory, rental, and asset management systems - IoT tracking and device management platforms - Enterprise dashboards and API-driven applications - Cloud-based applications and scalable backend systems 🚀 Selected Project Experience - Transportation Dispatch & Logistics Command Center - Vehicle Auction & International Shipping CRM - Inventory & Rental SaaS Platform - DigitalPersona Fingerprint Authentication System - IoT Device Tracking & Management Platform - Helium 5G & LoRaWAN Infrastructure Platform - LLM-powered applications, knowledge retrieval, and business workflow automation 🤝 Why Work With Me? - End-to-end ownership: From requirements and architecture to development, deployment, and maintenance. - Business-focused engineering: I understand the problem before choosing the technical solution. - AI + full-stack expertise: I can build the complete application and integrate Generative AI into its actual workflows. - Modern development approach: I use AI tools where they add value while keeping architecture, code quality, and maintainability in focus. - Technical leadership: Experience coordinating developers, managing project delivery, reviewing code, and making architecture decisions. - Clear communication: Regular updates, realistic expectations, and transparent discussions about technical trade-offs.
