Jammu, India - 5:28 am local time
I help startups, SaaS companies, and growing businesses automate operations, connect their tools, and build AI-powered products using **Python, AI agents, n8n, OpenAI, Claude, APIs, CRMs, and cloud infrastructure**.
My focus is on **production-ready automation** that reduces manual work, improves workflows, and can scale as the business grows.
What I Build:
• AI agents, multi-agent workflows & AI-powered applications
• Python, FastAPI & Django backend systems

Recent AI, Python & Automation Work:
1. Investment Education Platform - AI + Fintech
Built an investment education platform using Claude Code and AI-assisted development, integrating real eToro data and supporting a verified **70.81% win rate**. Worked with MCP browser automation, real-time market data, and an AI-driven development workflow that helped achieve significantly faster development cycles.
2. Mailchimp → GoHighLevel Automation
Created an **n8n workflow** that automatically syncs Mailchimp subscribers with GoHighLevel, including contact filtering, duplicate prevention, custom fields, and scheduled updates, eliminating manual synchronization.
3. Appreciate Wealth
Worked as a **Senior Python Developer** on async application design, API development, AWS integrations, and backend architecture using Python, Django REST Framework, Flask, PostgreSQL, microservices, and Docker.
CRM & Business Automation
I have experience integrating automation with HubSpot, GoHighLevel, Mailchimp, Stripe, Twilio, and other SaaS platforms, including contact synchronization, lead workflows, CRM updates, notifications, data enrichment, and custom API automation.
Technology Stack:
AI: OpenAI | Claude | Gemini | LangChain | LangGraph | RAG | AI Agents | MCP

Backend: Python | FastAPI | Django | Flask | REST APIs | Microservices
Data/Cloud: PostgreSQL | Supabase | Redis | Docker | AWS
CRM/Integrations: HubSpot | GoHighLevel | Mailchimp | Stripe | Twilio
Why Clients Work With Me:

• Strong Python/backend engineering foundation
• AI agents + n8n + APIs + CRM integrations in one workflow
• Experience with HubSpot, GoHighLevel and business automation
