Web Developer – Payment System Integration (Fixed Price)

SimpleVaad is a live platform, and we’re looking for an experienced Web Developer to implement a payment processing system — and nothing beyond that.

This is a fixed-price, fixed-scope project, not an hourly role and not an ongoing position.

• Implement a full payment flow using an external payment provider
• Handle payment creation, callbacks/webhooks, and status updates
• Ensure production-ready behavior (errors, edge cases, retries)
• Deliver a working and tested integration

• Proven experience with payment system integrations
• Strong TypeScript and/or Java background
• Ability to work with clear specs and deliver end-to-end ownership
• Comfortable with fixed-price project delivery

• Scope is defined upfront
• Fixed price agreed in advance
• Clear acceptance criteria
• Delivery-focused — no time tracking

Please include:

• Examples of payment systems you’ve implemented
• Your proposed fixed price
• Estimated delivery timeline

Only relevant, hands-on experience will be considered.
