Job Success
Mohali, India - 10:33 pm local time
I’m a Full-stack engineer (React, Next.js, Angular, Node.js, Python, Django, MySQL, TypeScript) with 15+ years shipping production web apps, SaaS products, APIs, and scalable business systems, plus AI automation (RAG chatbots, Voice AI, N8N workflows) built in where it creates real business value.
Since 2024, I’ve worked as a long-term contractor for a Healthcare Platform, contributing across both frontend and backend systems. I also run Team NironTech, my own development agency, where I build software products, AI automation tools, and custom business systems for clients.
My core strength is full-stack development. More recently, I’ve expanded into AI automation, helping businesses reduce repetitive work, automate customer interactions, and add practical AI features into their products and operations.
💻 Full-Stack Development
I help businesses build, improve, and scale modern web applications.
My development work includes:
• SaaS platforms and custom web applications
• React, Next.js, and Angular frontend development
• Node.js, Python, Django, and REST/Fast API development
• MySQL, Supabase, Firebase optimization and database architecture
• Frontend modernization and performance improvement
• CI/CD setup, build optimization, and deployment support
• Chrome extension development and internal business tools
I’m comfortable working on mature codebases with technical debt, performance issues, scaling challenges, and architecture problems that require senior-level debugging.
🤖 AI Automation & Intelligent Workflows
I build AI automation systems that solve real operational problems, not just “AI features” for the sake of it.
AI automation services include:
• Voice AI Agents using Twilio + OpenAI Realtime API
• RAG Chatbots for company docs, policies, and product data
• N8N Workflow Automation
• OpenAI API Integration and Claude Integration
• AI-powered lead qualification and customer support automation
• Internal tools that reduce manual data entry and repetitive work
🎯 Who I Work Best With
I’m a strong fit for:
• Companies needing voice AI or telephony automation
• Businesses with knowledge bases that need AI chatbots
• SaaS teams needing senior full-stack development support
• Founders building MVPs with AI features included from day one
• Established products needing React, Next, Node.js, Python or Supabase support
✅ How I Work
I use a structured, sub-task-driven development process with testing and review cycles. I don’t ship raw AI-generated code. Every solution is reviewed, refactored, and built for real-world use before delivery.
I’ve worked asynchronously with international teams for years, so I’m comfortable collaborating across time zones and fitting into existing workflows.
🚀 If you need a senior full-stack developer who can also bring practical AI automation into your product or business, send me a message and let’s discuss your project.
