A small marketing agency was manually copying project data and sending client invoices every week — a 3+ hour process. I built a Python automation script that pulls billing data directly from a CSV, generates branded PDF invoices for each client, and simulates sending them via email on a set weekly schedule with no manual input needed.

The script runs automatically, logs all sent invoices, and flags any missing data before sending.

Stack: Python, fpdf2, pandas, smtplib, schedule

Result: Eliminated 3+ hours of weekly manual work. Invoices now go out automatically every Friday at 9AM without the client touching anything.

I had the opportunity to work on another live platform for a business client. 🌐 https://tmsfurniture.in This project involved building and supporting a multi-store ecommerce and lead management platform designed to help customers explore furniture collections and connect directly with nearby stores as easy management by seperate dashboard for store owner - who controls everything and manager - controls specific store. Some of the areas I worked on: • Multi-store product catalogue system - Products with variants, category, banners, lead updations • Customer enquiry & lead management • Admin dashboard for store operations - Store Owner and Store Manager • Deployment and hosting setup - AWS EC2 and S3 • Continuous technical support and monitoring The platform has now been live in production for the past 4 months, running smoothly with stable performance and no major issues, which has been a great experience in maintaining real-world systems. It was rewarding to see the client happy with the outcome and how the platform helps improve their online visibility and customer enquiries.
