At Cubastion Consulting, I work on the AMC checkout-to-payment flow in Node.js and Express, supporting cash and cheque, payment gateway, SMS payment link, and QR code payments. I implemented transaction verification and a scheduled re-verification job that cut manual follow-ups by 35%.
I also automated post-payment steps: receipts are sent by SMS, and plan-specific PDF invoices are generated with EJS and Puppeteer and emailed through Nodemailer. Earlier, as a Graduate Trainee Engineer at Cubastion Consulting, I built an appointment rescheduling system with SMS verification and configurable scheduling rules.
In my projects, I developed Code Cafe, an online judge with a Django backend and a Python-based compilation system, and WorkWave, a freelance service platform with PayPal payment integration. I work with React, Node.js, Express, Django, MongoDB, and PostgreSQL.
