Full Stack Devs Needed, Join our team! (NodeJS and Angular)
Shiv helped us to move our Angular 11 project forward by adding new features. He worked mainly on the front end of the application and this is where his skills seemed to be best suited. He worked on a range of areas to help improve our system. He had good communication skills and would sometimes fix up bugs and apply fixes out of hours so that other team members were able to continue their work which was good. Thanks Shiv!

If you need a system that actually scales, automates workflows, and doesn’t break under load! that’s where I come in.
👋 Hi, I’m a Full-Stack Developer with 8+ years of experience building production-grade applications used in real business environments.
I specialize in building systems that combine:
• Modern frontend frameworks
• Scalable backend architecture
• High-performance APIs
• Intelligent search systems
• AI-powered features
From SaaS platforms and internal tools to AI-enhanced web applications, I design systems that are maintainable, fast, and built to scale.
I help businesses reduce manual work, improve user experience, and ship faster using AI-assisted systems.
I work across the full stack using React, Vue, Next.js, Nuxt.js, Node.js, Nest.js, MongoDB, and GraphQL, enabling me to take products from:
Idea → Architecture → Development → Deployment
━━━━━━━━━━━━━━━━━━━━━━
🛠 What I Build for Clients
• Full-stack SaaS platforms
• AI-powered web applications
• Internal dashboards and operational tools
• High-performance Node.js backend systems
• Real-time applications and data platforms
• Custom search engines using ElasticSearch or Typesense
• Cross-platform desktop applications using Electron
• Headless eCommerce platforms
━━━━━━━━━━━━━━━━━━━━━━
🤖 AI & Intelligent Systems
I help businesses integrate AI capabilities directly into their products and workflows.
Examples include:
• AI chatbots powered by modern LLMs
• Retrieval-Augmented Generation (RAG) systems
• AI-powered internal assistants
• AI search and knowledge systems
• AI-driven workflow automation
AI models and platforms I commonly work with:
• OpenAI (GPT-4 / GPT-4o)
• Google Gemini
• Anthropic Claude
• GitHub Copilot
• OpenClaw
Modern AI development environments and coding agents:
• Cursor
• Claude Code
• GitHub Copilot
• Windsurf
• Antigravity
AI-powered MVP and product development tools:
• v0.dev
• Bolt.new
• Lovable.dev
• Builderio
• Replit AI
These tools allow me to accelerate development while maintaining production-level engineering quality.
🧠 Agentic AI Workflows (Real Implementations)
Beyond standard AI integrations, I design and build agent-driven workflows that automate decision-making and multi-step processes.
Recent work includes:
• Built a production-ready chatbot using Vector Databases + Enhanced RAG pipelines, improving response relevance and contextual accuracy across large knowledge bases
• Designed agentic LinkedIn automation workflows (n8n) that:
• Identify and track high-quality posts
• Generate contextual comments
• Maintain structured logs of engagement for analysis
• Developed a UI/UX automation system using agent workflows (n8n) that:
• Analyzes UX flows and detects friction points
• Suggests color palettes, typography, and UX improvements
• Generates structured wireframes
• Converts approved wireframes into UI-ready outputs
These systems combine LLM reasoning, structured workflows, and automation tools to reduce manual effort and accelerate product iteration.
