FinTech software development
Software where every number adds up.
Financial software has no room for rounding errors or missing records. I built QistPay, an installment management platform that tracks orders, monthly installments, payments, investors and profit for real businesses, and I bring the same care to every finance project.

Common questions
Have you built financial software before?
Yes. QistPay is my own installment management SaaS. It handles orders, monthly installments, payments, investors and profit analytics for real businesses.
How do you make sure calculations are correct?
Money logic gets automated tests for edge cases like partial payments, edits to paid installments and rescheduling, plus audit logs so every change can be traced.
Can you integrate local payment gateways?
Yes. I integrate international and local payment gateways and build reconciliation so payments match your records.
