What We Build

Embedded firmware, custom hardware, IoT systems, and touchscreen interfaces — end-to-end engineering for products that actually ship.

Embedded Firmware

Code that runs on metal, not assumptions.

Firmware is the heartbeat of every embedded product. We write it right from the start — structured, testable, and built for the environment it will actually live in.

Whether you need a bare-metal driver layer, a real-time task architecture, or a full embedded Linux distribution, we work at the level your product demands.

Every codebase we deliver is clean, documented, and yours to own and extend after engagement.

BARE-METAL

Bare-Metal Firmware

Tight, deterministic firmware written directly against the hardware — no OS overhead, full control over timing, peripherals, and power.

Learn More →
RTOS

RTOS-Based Systems

FreeRTOS and Zephyr architectures for multi-tasking embedded products that need reliable task scheduling and power-managed sleep modes.

Learn More →
EMBEDDED LINUX

Embedded Linux

Yocto and Buildroot-based Linux systems for connected products requiring rich networking stacks, OTA updates, and application frameworks.

OTA & SECURITY

OTA Updates & Secure Boot

Field-proven OTA pipelines and secure boot chains that keep deployed devices updated, authenticated, and protected in the wild.

Hardware Design

From schematic to certified, manufactured board.

Great firmware needs great hardware underneath it. We design custom PCBs with manufacturing in mind from day one — not as an afterthought when the prototype already exists.

We handle component selection, schematic capture, PCB layout, DFM review, and liaison with your contract manufacturer — keeping the process tight and the BOM lean.

Our hardware has shipped in outdoor enclosures, kiosk cabinets, and industrial installations across Kenya and beyond.

SCHEMATIC & LAYOUT

PCB Design

From microcontroller selection to final Gerbers — we design boards that are manufacturable, testable, and built to last in real environments.

DFM

Design for Manufacturing

BOM optimisation, DFM reviews, and contract-manufacturer hand-off that bridge the gap between first prototype and volume production.

POWER ELECTRONICS

Power Supply Design

Multi-rail supplies, battery management systems, and MPPT circuits for products powered by mains, LiPo, or solar — from milliwatts to kilowatts.

IoT Products

Connected devices, built end-to-end.

An IoT product is more than a device with Wi-Fi. It is a system — hardware, firmware, cloud, and app working together without friction. We build all of it.

From sensor nodes that run for years on a coin cell, to LTE-connected industrial gateways pushing telemetry across hundreds of field sites — we've shipped IoT systems at both ends of the complexity spectrum.

We help you choose the right connectivity technology, design the right architecture, and get to market without rebuilding it twice.

CONNECTED DEVICES

End-to-End IoT Products

We take your IoT idea from napkin sketch to deployed product — hardware, firmware, cloud backend, and mobile app all under one engineering roof.

Learn More →
CLOUD & API

Cloud Integration & APIs

RESTful and MQTT backends that connect your devices to dashboards, third-party platforms, and mobile apps — reliably and at scale.

Learn More →
PROTOCOLS

Wireless & Protocol Integration

LTE, LoRaWAN, BLE, Wi-Fi, Modbus, CAN — we select and implement the right communication stack for your product's range, power, and data needs.

Learn More →
MOBILE

Companion Mobile Apps

Android and iOS apps that give users and operators real-time visibility into their devices — pairing, monitoring, configuration, and alerts.

HMI Development

Touchscreen interfaces that feel deliberate.

A good embedded UI is invisible — users complete their task without thinking about the interface. We design and build HMIs that hit that bar, whether it's a 10-inch industrial kiosk or a small 2.8-inch status display on an MCU.

Our Qt/QML work runs on embedded Linux platforms with smooth, GPU-accelerated rendering. Our LVGL work runs on microcontrollers with no Linux at all — just a tight draw loop and clean widget logic.

Both approaches are designed to survive production environments — high brightness, gloves, dust, and continuous operation.

Qt / QML

Qt/QML Interface Development

High-performance touchscreen UIs built with Qt/QML on embedded Linux — smooth animations, offline-capable, and production-hardened.

Learn More →
LVGL

LVGL on Microcontrollers

Beautiful, lightweight GUIs on resource-constrained MCUs using LVGL — ideal for small displays that don't need a full Linux stack underneath.
