Custom Software & Firmware
Engineering the Intelligence That Connects Hardware, Software, and Users
Modern products depend on software running across multiple layers—from embedded firmware inside the device to cloud platforms, mobile applications, APIs, and enterprise systems.
SDI develops custom software and firmware that work together as one connected ecosystem, enabling products to communicate, automate, and scale from prototype through commercial deployment.
One Product. One Software Ecosystem.
Successful products require more than firmware or a mobile app.
They require software that connects every layer of the product lifecycle—from sensors and embedded processors to cloud services, business systems, and customer applications.

Common questions about custom firmware, backend platforms, OTA updates, cloud integration, and lifecycle support.
What microcontrollers and processors do your firmware engineers support?
We develop firmware across a broad range of architectures, including ARM Cortex-M/A series, ESP32, STM32, Nordic Semiconductor for BLE, NXP, and TI microcontrollers, scaling up to Linux-based embedded processors.
Can you modernize firmware on an existing hardware product?
Yes. We routinely analyze legacy hardware codebases, optimize poorly written firmware, patch security gaps, and add features like OTA capabilities to bring existing devices up to modern commercial standards.
How do you handle Over-the-Air (OTA) firmware updates securely?
We build robust, secure OTA pipelines that feature cryptographic signature verification, dual-partition bootloaders (to prevent bricking devices if an update fails), and encrypted transit channels.
What communication protocols do you use for device-to-cloud sync?
Depending on power constraints and data usage, we implement MQTT, CoAP, HTTP/REST, and WebSockets to optimize latency, security, and battery longevity.
Do you design custom backend platforms and APIs for hardware management?
Yes. We develop highly scalable backends and secure REST or GraphQL APIs that route, store, and process high-volume sensor streams coming from thousands of edge units.
How do hardware and software engineering teams collaborate at SDI?
Our hardware, firmware, and software engineers sit under one roof. Circuit designs are vetted against software footprints early on, preventing late-stage integration conflicts between the physical PCB and application layer.
Is your custom software compliant with medical or industrial standards?
Yes. We design custom software systems following industry-specific standards, implementing strict data encryption, secure audit logs, and redundant fail-safes for healthcare and industrial systems.
What cloud providers do you integrate with?
We are platform-agnostic and design software architectures for AWS (IoT Core), Microsoft Azure (IoT Hub), and Google Cloud Platform, depending on your enterprise's IT infrastructure requirements.
What happens if our cloud database drops connection with our edge device?
We architect firmware with edge caching and local storage capabilities, allowing your device to log vital data locally and securely upload it once reconnection is safely established.
Do you provide software updates and support after product manufacturing begins?
Yes, we provide full product lifecycle management. Our teams handle continuous performance monitoring, API adjustments, security patching, and ongoing feature expansion long after production launch.
