About this gig

I will build you a fully working payment card tokenization vault from scratch.


This is a real fintech application that collects customer card data through a secure checkout form, encrypts it using AES-256-GCM military-grade encryption, stores it permanently in a PostgreSQL database, and displays it on a private records dashboard.


What you get:

Live checkout form that collects card data

AES-256-GCM encryption on card numbers and CVV

PostgreSQL database setup (never loses data)

Private records dashboard with CVV decryption

Full source code delivered via GitHub

28-page documentation explaining every step

Post-delivery support to help you get it running


Tech stack:

Node.js TypeScript Express PostgreSQL Render


Perfect for:

- Fintech startups needing payment infrastructure fast

- Developers who want to understand card tokenization

- Anyone building a checkout system from scratch


Basic source code + docs delivered

Standard source code + I help you deploy it

Premium full setup + custom domain + 30 days support


Built and deployed by HTXDrop. This is not a template it is a real working system built from scratch.

I build payment infrastructure and teach others how to do the same. I created a fully working card tokenization vault from scratch using AI prompts, Node.js, AES-256-GCM encryption, and PostgreSQL — with zero traditional coding background. I offer fintech development services, source code delivery, and technical education. Whether you need a payment vault built for your business or want to learn how to build one yourself, I can help.
