About

Building Intelligent Systems, Not Just Websites.

I'm Mirjahan Ali, an AI Developer and Automation Engineer from Kolkata, India. I combine AI, automation and software development to solve practical business problems — not build decorative demos. My work connects AI agents, n8n workflows, chatbots, APIs and custom software into systems that actually run parts of a business.

Instead of manually copying data, chasing leads or answering the same questions all day, businesses use my systems to make those things happen automatically. Whether it's a single workflow or a full SaaS platform, I build from the business problem backward — so the result is practical, reliable and measurable.

Selected Work

A snapshot of the AI, automation and software systems I build. Every project follows the same principle: solve the real business problem, cleanly.

AI + n8n + APIs + Web App

AI Business Automation Platform

OpenAIn8nNode.jsREST APIs

Challenge

A growing business was drowning in manual data entry and repetitive follow-ups across disconnected tools.

Solution

Designed an AI-powered automation platform that orchestrates data flow between the web app, APIs and AI models, handling repetitive work automatically.

Result

A central platform where routine business processes run automatically and staff focus on work that needs human judgment.

AI + Chatbot + API + Automation

AI Customer Support System

AI ChatbotLLM APIWebhooksCRM

Challenge

Customer queries piled up during and after business hours, and support teams re-answered the same questions daily.

Solution

Built an AI customer support system that understands queries, answers from the business's own knowledge base, and routes complex issues to the right person.

Result

Customers get instant, accurate answers any time of day while the support team handles only the conversations that truly need them.

SaaS + Database + API + Web Application

Business SaaS Platform

ReactNext.jsPostgreSQLNode.js

Challenge

A manual process running on spreadsheets had no real-time data, access control, or way to scale.

Solution

Developed a custom SaaS platform with a secure database, structured API and responsive web application tailored to the business workflow.

Result

A reliable, scalable platform where data is centralized, always current, and every user works from a single source of truth.

n8n + CRM + AI + Messaging

Lead Automation System

n8nWhatsApp APICRMAI

Challenge

Incoming leads went cold because there was no fast, consistent follow-up and no structured qualification.

Solution

Automated the full lead pipeline: capture, AI qualification, CRM logging and instant WhatsApp follow-up, all connected through n8n.

Result

Every lead is contacted within minutes, qualified automatically, and tracked in the CRM without manual effort.

Web App + Database + Automation

Custom Business Management System

Web AppDatabaseAutomationDeployment

Challenge

Operations were scattered across documents and manual updates, making reporting slow and error-prone.

Solution

Built a custom management system with role-based access, automated reporting and integrated workflows tailored to the operation.

Result

A single system that runs day-to-day operations and generates reports automatically, replacing hours of manual work.
