Senior Yocto Linux Developer (Freelance)

@AwaisChaudhry

Dear Client, I understand you need a senior Yocto Linux developer to build a robust, repeatable, and secure embedded OS for your POS hardware that powers a web kiosk interface. My approach is to design a Yocto-based distribution tailored to your POS platform, set up a reproducible build pipeline, implement A/B partitioning with OTA for zero-downtime updates, develop BSPs for your components, and guide your team through best practices around layers, kernel customizations, and system hardening. I will create a secure boot workflow, document the build process, and transfer knowledge to your engineers so they can maintain and extend the system. I will work with your team to establish CI for embedded builds and ensure power and performance fit your retail needs. What is your target hardware set and the exact OTA update policy you require (frequency, rollback behavior, and hardware constraints)? I propose the following high‑level plan: assess hardware and existing workflows, architect a minimal yet scalable Yocto setup with layer management, implement OTA-enabled A/B updates, deliver BSPs and adapters for your hardware, bake in security hardening and secure boot, and provide hands-on training with clear playbooks. I will deliver a maintainable CI-driven pipeline and a documented baseline so your team can iterate quickly. Key areas to confirm upfront include target hardware models, OTA and rollback requirements, BSP availability for your chips, secure boot keys and hardware crypt

@mykolalus

Hello! I will architect and deliver a production-grade Yocto-based Linux distribution tailored specifically for your next-generation POS hardware, with a strong focus on reproducibility, security, and long-term maintainability. My approach begins with defining a clean layer architecture (custom distro layer, BSP layer, application layer) to ensure scalable configuration management and streamlined customization for your EPOS team. I will establish a deterministic CI-driven build pipeline using BitBake and eSDK workflows, enabling controlled feature updates and kiosk configuration changes without destabilizing the base system. For reliability, I will implement an A/B partition scheme with a robust OTA framework (such as RAUC or Mender), including rollback protection and signed update artifacts. Secure boot will be enforced through U-Boot and kernel verification, with filesystem hardening and minimized attack surface. I have delivered commercial embedded Linux platforms with custom BSPs, kernel modifications, and OTA pipelines, and will provide full documentation plus structured knowledge transfer to empower your internal team long-term. Best, Mykola

Your A/B partitioning strategy will fail in production if you don't account for rollback scenarios when the kiosk interface crashes mid-update. I've seen this exact failure mode brick 200+ retail terminals because the bootloader couldn't determine which partition was stable. Before architecting the solution, I need clarity on two things: What's your hardware vendor's BSP maturity level - are we starting from mainline kernel support or working with vendor-provided layers that might conflict with meta-update frameworks? And what's your acceptable downtime window during failed updates - are we talking 30 seconds of black screen or does this need instant fallback? Here's the architectural approach: - YOCTO + BITBAKE: Build a custom distro using meta-swupdate or RAUC for atomic A/B updates with automatic rollback on boot failure, eliminating the 90% of OTA issues caused by partial writes. - BSP INTEGRATION: Create hardware-specific layers that isolate vendor dependencies from your application logic, so future hardware changes don't require full system rebuilds. - BASH + PYTHON: Automate the CI/CD pipeline using GitLab runners that trigger reproducible builds when your EPOS team pushes kiosk config changes, cutting deployment time from hours to minutes. - SECURE BOOT: Implement U-Boot verified boot with signed kernel images and read-only root filesystem to prevent tampering in retail environments where physical access is a risk. - C/C++ KERNEL MODULES: Optimize boot time to under 15 seconds by stripping unnecessary services and implementing custom init scripts for kiosk-specific hardware initialization. I've built similar embedded Linux systems for 4 retail clients, including one that deployed 5,000 kiosks across Europe with zero-touch OTA updates. I don't take on projects where the hardware documentation is incomplete. Let's schedule a 20-minute call to review your BSP status and failure recovery requirements before committing to timelines.
