    What we will do for your project

    Firmware architecture for a specific device

    We analyze device architecture, tasks, microchips, and communication protocols. We prepare technical documentation and interaction maps.

    Core firmware and logic development

    We write low-level code for sensors, communication modules, displays, power management, and more — ensuring stability and security.

    Cloud, application, and API integration

    We integrate firmware with mobile apps, backend servers, BLE/Wi-Fi, MQTT, and other communication layers.

    OTA firmware updates and protection

    We implement secure over-the-air (OTA) updates and protect firmware from reverse engineering or unauthorized copying.

    Testing, debugging, and optimization

    We test firmware on real hardware, profile performance, reduce power consumption, and improve responsiveness.

    Device support and maintenance

    We provide ongoing support, updates, and firmware adaptation for new hardware revisions.

      Testimonials

      Мы заказывали у KISS Software анимацию для 2D-платформера. Ребята сразу поняли нашу стилистику, предложили интересные решения по эмоциям персонажей, а результат превзошёл ожидания. Игроки отмечают именно «живость» анимации. Будем работать ещё.
      Андрей
      гейм-дизайнер
      Нужно было подключить аутсорс на этапе риггинга и внутриигровых синематиков под Unreal Engine. KISS вошли в проект аккуратно, без долгих вводных, всё отдали в срок, багов — ноль. Отличная техничка, быстрая реакция и понимание продакшн-процесса.
      Михаил
      продюсер, студия разработки игр
      Уже третий проект делаем с командой KISS — всегда всё прозрачно, по делу и вовремя. У них реально хорошее чувство гейм-драмы и движущейся композиции. Отдельно ценим их подход к оптимизации под мобильные платформы.

      Device and requirements analysis
      We analyze hardware platforms, peripherals, communication protocols, and firmware responsibilities. Define hardware limitations and cloud/API interactions.
      Time to deliver
      ~ 1-2 days
      Architecture and technology selection
      We design firmware architecture, select languages (C, C++, Rust), RTOS (if required), and protocol stacks.
      Time to deliver
      ~ 2-4 days
      Driver and low-level development
      We develop drivers for sensors, modems, displays, and controllers. Ensure stability, proper timing, power efficiency, and fault prevention.
      Time to deliver
      ~ 3-7 days
      Integration with external components
      Firmware integrates with mobile apps, servers, gateways, and controllers. Secure data transfer, encryption, and validation are implemented.
      Time to deliver
      ~ 5-15 days
      On-device testing and debugging
      We test firmware directly on hardware, analyze logs, simulate edge cases, and optimize reliability and power usage.
      Time to deliver
      ~ 2-4 days
      Support and firmware evolution
      We add new features, adapt firmware for new hardware revisions, implement OTA updates, and support production scaling.
      Time to deliver
      ~ 1-2 days
