Instant multilingual rollout for all merchant products

[01]SYSTEM OVERVIEW

A backend HTML localization framework designed to provide instant multilingual support across Juspay's product suite without per-language frontend deployments.

The Engineering Challenge

Global merchants required payment pages in local languages, but previous solutions needed separate frontend builds and deployments per locale, creating significant operational overhead.

Implemented Solution

Engineered a backend translation layer that intercepts and translates HTML payloads based on merchant language preferences before delivery.

[02]SYSTEM ARCHITECTURE

Middleware translation layer processing HTML payloads at the edge
Centralized translation key management with fallback hierarchy
Merchant language preference resolution from session and gateway config
