Are you looking for a developer who can build both modern web applications and AI-powered solutions?

I help startups, agencies, and SaaS companies build scalable products using the MERN stack while integrating advanced AI capabilities such as RAG systems, AI chatbots, autonomous agents, workflow automation, and LLM-powered applications.

Over the last 5+ years, I have built and maintained:

• Full SaaS platforms with subscriptions, billing, and role management
• AI-powered chatbots using OpenAI and Retrieval-Augmented Generation (RAG)
• Agentic AI workflows that interact with APIs, databases, and business processes
• n8n automations for lead management, customer support, notifications, and business operations
• Admin dashboards, analytics platforms, and internal business tools
• Secure authentication systems using JWT, OAuth, and RBAC
• REST and GraphQL integrations with third-party services, payment gateways, CRMs, and AI platforms
• Modern React.js and Next.js applications with responsive user experiences

Common client challenges I solve:

• Building AI chatbots trained on company documents and knowledge bases
• Creating RAG systems that provide accurate and context-aware answers
• Automating repetitive business tasks using AI and n8n
• Scaling SaaS applications without sacrificing performance
• Refactoring messy codebases into maintainable, production-ready systems
• Connecting multiple services, APIs, databases, and AI tools into a unified workflow

Working with me, you will:

✅ Get scalable full-stack applications built with modern architecture
✅ Launch AI chatbots, AI agents, and RAG systems faster
✅ Automate business workflows and reduce manual work
✅ Receive clean, maintainable, and well-documented code
✅ Improve user experience with responsive and performant interfaces
✅ Work with a single engineer who understands frontend, backend, databases, AI, and automation

If you need someone to:

• Build a full MERN Stack web application from scratch
• Develop AI Chatbots powered by OpenAI, RAG, and custom knowledge bases
• Build AI Agents that can perform tasks, interact with APIs, and automate workflows
• Create n8n automations to streamline business operations and reduce manual work
• Refactor and optimize a slow, buggy, or difficult-to-maintain application
• Add new modules such as dashboards, reporting, analytics, admin panels, and internal tools
• Integrate third-party APIs, payment gateways, CRMs, and AI services
• Implement secure authentication, authorization, and role-based access control
• Build SaaS platforms with scalable architecture and clean code
• Prepare your product for launch with a stable, secure, and production-ready foundation

I am here to help.
