Case Study: MySTC at Telecom Scale

Context

MySTC serves core customer journeys at telecom scale. The app had to support account lifecycle operations, ordering flows, and support workflows while keeping interaction latency stable on mid-range devices.

Stack

• Kotlin, Java, MVVM
• Firebase for operational integrations
• SQLite-backed offline pathways for selected flows

Key Challenges

• Data synchronization across volatile network conditions
• Multi-language parity and layout resilience

Contributions

• Led a team of five senior Android engineers
• Defined delivery sequencing for major feature enhancements
• Drove targeted performance and stability improvements

Outcome

We improved release confidence through better modular boundaries and stronger validation loops, reducing integration friction while keeping customer-critical flows reliable.
