Hi, I'm a full stack developer who turns ideas into real, working products.
I've built a complete SaaS POS system from scratch — used by real shops — with AI insights, inventory, billing, WhatsApp alerts, and cloud backup. Every line, by myself.
I work with:
→ Python, Flask, PostgreSQL, SQLite
→ SaaS & business web apps
→ AI features & API integrations
→ Desktop software & Windows apps
I care about one thing: software that actually works.
Message me before you order. Let's talk.
FAQ
Do I get the source code after delivery?
Yes. You receive full source code with no restrictions. It is your software — you own it completely. No licensing fees or hidden conditions.
Can multiple employees use the app at the same time?
Yes. Multi-user support with roles (Admin, Manager, Cashier etc.) is included from the Standard package. Each user has their own login and access level.
Will the app work on mobile devices?
Yes. All interfaces are built responsive — they work on desktop, tablet, and mobile browsers without a separate mobile app.
Can you deploy it online so users can access it from anywhere?
Yes. Standard and Premium packages include cloud deployment on Render or VPS. Users can access the app from any device with a browser.
What if I need new features added after delivery?
I offer ongoing support and feature additions. Small changes are handled via messages. Larger features are scoped as a new order. Many clients work with me long-term.
