Mapians.com is an international D2C provider offering global travel eSIM data packages for travelers across 150+ countries. They needed a high-performance, mobile-first web application capable of issuing digital eSIM profile QR codes instantly upon payment.
Scale & Operating Footprint
High-volume operational workload operating across Travel & Mobility with distributed end-users, requiring strict uptime SLAs and seamless transaction throughput.
Architect and deploy a high-performance, automated platform that eliminates manual dependencies and sustains uninterrupted multi-channel growth.
02. Operational Bottlenecks & Legacy Friction
Problem: Business Challenges Before Involve
Legacy platform timeouts during peak travel seasons resulted in delayed eSIM QR code emails and high customer support ticket volumes. Manual order verification created friction for international buyers using multi-currency cards.
Throughput Bottlenecks
System performance degradation and database locking occurred during peak concurrent request bursts, risking revenue and user drop-off.
Data Silos & Friction
Disjointed data repositories forced operational teams to manually extract, manipulate, and reconcile spreadsheets daily.
Integration Fragility
Lack of automated error-handling pipelines caused silent payload failures and delayed sync across internal departments.

Critical Core Impact:Legacy technical debt impaired development velocity, introduced administrative overhead, and restricted Mapians.com from expanding into higher-volume channels.
