About me
Business software developer from Pakistan. I build billing, invoicing and POS
systems with Python, Flask and SQLite — and I deploy them myself, so you get a
live login link, source code and a system ready to use.
Built: cloud invoice & billing SaaS (every company's data isolated) ·
restaurant POS with receipts and daily sales reports · school fee challans ·
office GST billing with A4 printing and multi-user logins.
Message me before ordering — I'll confirm exactly what's possible for your

I am incredibly happy with the logo design! It exceeded my expectations in both quality and creativity. The designer worked very quickly and delivered the final product faster than I anticipated. Communication was clear and professional throughout the process, and they were open to feedback. Highly recommend for anyone looking for quality and fast service!
