Custom AI Assistants & Automated Workflows for Business

CMS: Secure Payments. Smarter Operations. A payment integration is not just about connecting a gateway. For this project, I designed and implemented a wallet-based payment workflow where users can recharge their wallet, use the balance for services, and have every transaction tracked with clear status and refund controls. The goal was simple: make payments reliable, traceable, and easy to manage for both users and administrators. Built with .NET Core, React, SQL Server, PayU and JWT Authentication. I enjoy taking a business process that feels fragmented or manual and turning it into a simple, practical digital solution.

Cover image for Mittu — Multilingual WhatsApp AI
Mittu — Multilingual WhatsApp AI Agent for Local Businesses The Problem: Small retail shop owners and local businesses in India don't want another bloated dashboard or complex management software. They want to type a quick message in their everyday language and get business handled immediately—logging orders, generating invoices, and checking sales without friction. The Solution: I built Mittu, a conversational AI assistant on WhatsApp designed specifically around how Indian retailers actually communicate. Mittu operates directly inside WhatsApp, allowing store owners to manage daily operations entirely in Hindi and Hinglish. Key Features & Capabilities: Conversational Order Intake: Parses multi-item orders with customer names and pricing directly from natural, free-form text. Automated GST Invoicing: Calculates tax breakdowns (GST @ 18%) and generates structured invoice numbers (INV-xxxx) on demand. On-Demand Business Intelligence: Summarizes daily and weekly revenue, top-selling items, and transaction logs via simple voice/text prompts. Natural Hindi/Hinglish Processing: Built to understand mixed-language phrasing, colloquial terms, and localized business terminology. Architecture & Tech Stack: Core Agent Logic: Python LLM Engine: Groq (LLaMA 3.3) for low-latency reasoning and conversational routing Database & Memory: Supabase for customer order history and transaction tracking Messaging Layer: Twilio WhatsApp Business API Pitch / Call to Action: Looking to build custom AI agents that automate customer operations or bridge English-only AI tools into local languages? Let's connect and build it.

Cover image for QuickServe — AI Natural Language
QuickServe — AI Natural Language Business Portal & Automated Service Hub The Problem: Traditional business portals require navigating multi-level menus just to check account metrics or raise a support ticket. QuickServe replaces that complexity with conversational actions backed by secure backend execution. Key Deliverables & Architecture: Natural Language Data Access: Queries live balances and recent transaction records directly from SQL Server using structured OpenAI tool calls. Conversational Service Actions: Triggers backend service tickets and workflows straight from the chat interface. Fault-Tolerant Fallback Layer: Rule-based fallback logic ensures critical business queries remain functional even if third-party AI APIs experience downtime. Tech Stack: .NET Core, React, SQL Server, OpenAI API.

Cover image for I wanted to share an
I wanted to share an internal dashboard I just wrapped up using the new Retool App Builder. The project targets a unique niche: Art Cafes & DIY Craft Studios. These businesses operate on a "Time-as-a-Service" model where customers book a 2-hour window, get basic supplies and a complimentary drink, but get charged for regular cafe snacks, premium canvases, or extra time. Standard POS platforms don’t natively track live table occupancy time or handle mixed complimentary/paid item orders smoothly. I built this custom portal to handle the heavy lifting. Here is a quick video walkthrough of the operational flows, live floor tracking, and dashboard settings: https://www.loom.com/share/7f8c823309ec4a24a392c5d427f21035 Key features built completely in Retool: Live Studio Floor/Dashboard: A clean grid layout displaying currently occupied tables, dynamically tracking group size, and color-coded status pills (Active, Completed, Unpaid). Contextual Orders (Modals): Clicking any active card triggers a popup modal form allowing front-desk staff to instantly append food items or premium inventory directly to that specific customer's active session tab. Back-Office Configuration & Reports: Dedicated tabs for the store owner to track key metrics (Active Sessions, Total Profits, Unpaid Orders), manage global inventory logs, and edit customer profile records. I’d love some feedback from the community: Drop your thoughts below or let me know if you want a breakdown of any specific component setups!
