BigBattery
Tiempo completo • 4 yrs 6 mos
BigBattery - WooCommerce Development and Store Optimization
Dec 2024 - Present • 1 yr 6 mos
BigBattery needed a production e-commerce store that could handle a complex battery catalog, product filtering by category and voltage, customer-facing tools, and reliable updates without fragile manual deployments. I worked on the WordPress/WooCommerce side: custom child theme work, PHP hooks, JavaScript-based dynamic product filtering, mobile-responsive filter modals, an energy usage calculator, Stripe/Klarna payment setup, and Git-based deployment through Pressable with GitHub webhooks. The result was a live e-commerce store with a more maintainable codebase, cleaner product discovery, and a safer release process for ongoing store changes.
BigBattery Husky 2 - Native iOS and Android Apps
Dec 2024 - Present • 1 yr 6 mos
BigBattery Husky 2 is a mobile monitoring app for battery management systems. Operators need to see voltage, current, temperature, state of charge, and cell-level battery health directly from their phones. I built native apps for both platforms instead of using a cross-platform shortcut: Swift/UIKit/RxSwift on iOS and Kotlin/MVVM on Android. The apps include real-time dashboards, session persistence, auto-reconnection, custom UI widgets, and support for multiple battery data points. Both versions were released to production. The Android app reached v3.0.7 with 19 builds, and both iOS and Android versions are available on the App Store and Google Play.
BigBattery Husky 2 - BLE Hardware Integration
Dec 2024 - Present • 1 yr 6 mos
BigBattery Husky 2 required reliable Bluetooth Low Energy communication between mobile apps and battery management hardware. This was not a simple BLE connection screen: the device used a custom Modbus-like protocol with multi-frame messages, CRC16 integrity checks, and cell-level battery data. I implemented the BLE layer on both iOS and Android, including device discovery, connection handling, packet parsing, multi-frame reassembly, CRC validation, reconnect behavior, and real-time updates for 32+ battery cells. This is the production proof behind my BLE/IoT Fiverr gig: custom hardware communication, not hobby-level Arduino work.
