Context & Challenges
A global technology company developing a new generation of Android-based Point-of-Sale (POS) devices built on Qualcomm QCS5430 and QCS6490 SoCs needed to scale its software platform across multiple product cycles.
To support rapid product rollout and long-term platform evolution, the customer engaged BayLibre in a staff augmentation model, embedding engineers within their internal teams over an extended period.
The engagement introduced several key challenges:
- Coordinating development across distributed teams and multiple time zones
- Supporting simultaneous POS product launches and maintenance cycles
- Building a reusable platform foundation across an entire POS product line
- Managing deep complexity across bootloader, Linux kernel, and Android stack
- Ensuring high reliability, security, and performance required for retail environments
- Integrating AI-driven development workflows into engineering processes
- Preparing for Android version migrations (A10 → A14 → A16) without disrupting deployed systems
BayLibre acted as a trusted extension of the customer’s engineering organization, contributing across all layers of the POS platform.
Achievements
BayLibre enabled the customer to scale execution and deliver a robust, production-grade POS platform across multiple device generations.
Key achievements included:
- Seamless collaboration with internal teams across global time zones
- Rapid team scaling (4× growth within one year) while maintaining development quality
- Design and development of low-level bootloader and kernel components, from early development boards to production POS devices
- Full support of Linux and Android platforms throughout development, integration, and validation phases
- Resolution of complex kernel and bootloader issues impacting device stability
- Development of custom kernel drivers for POS-specific hardware (I/O, peripherals, payment interfaces)
- Implementation of security enhancements aligned with retail and payment system requirements
- Delivery of post-release updates and new features, extending device lifecycle in the field
This long-term collaboration allowed the customer to accelerate time-to-market while ensuring a stable and scalable POS platform.
Open-Source Story
Despite integrating proprietary components, the project followed strong open-source engineering principles.
BayLibre ensured that:
- Standard Linux and Android frameworks were used wherever possible
- Platform code remained clean, modular, and maintainable
- Customizations were minimized to reduce fragmentation
- Development practices aligned with upstream Linux and Android evolution
This approach enabled smoother upgrades, reduced maintenance burden, and improved long-term sustainability of the POS platform.
