Embedded design & firmware
Low-level firmware in C/C++ and assembly, custom bootloaders, device bring-up, board diagnostics and field-update strategies tailored to your hardware.
From Embedded Systems to Complete Software Solutions
We bring embedded hardware & modern software together for real-world products.
ToughDev Studio is a small, hands-on engineering team specialising in embedded systems, hardware restoration, reverse engineering, and custom tools for specialised and unconventional platforms. We design, repair, and integrate systems that few teams specialize in, occasionally pairing them with simple desktop or mobile front ends.

About the studio
A small team obsessed with how systems really work.
ToughDev Studio brings together embedded engineers, full-stack developers, and embedded hardware enthusiasts. Our background spans bare-metal firmware, Windows internals, custom bootloaders, and modern cloud-backed applications.
We are comfortable stepping into unusual environments: legacy industrial systems, vintage PCs, control boards and one-off hardware that must not fail. From protocol sniffing and board-level diagnostics to building user-facing tools, our goal is simple: make complex systems understandable, reliable and useful again.
What we do
From firmware and drivers to tools your team can use.
Legacy & retro systems
Restoring and extending vintage PCs, DOS/Windows 9x systems, BIOS environments and industrial controllers so they can keep doing their jobs.
Reverse engineer
Protocol analysis, firmware inspection and related tools to understand undocumented behaviour, unlock integrations and support long-term maintenance.
Desktop, mobile & web apps
Operator consoles, monitoring dashboards and companion apps that speak your device’s language and make complex systems approachable for users.
VoIP systems & telephony
Design, troubleshooting and integration of reliable VoIP solutions using open-source and commercial platforms, from small deployments to custom call flows.
Infrastructure & support
Pragmatic, maintainable environments for your systems: from build chains to small server footprints across Windows and Linux platforms.

Tell us about your projects, old or new.
We usually work with engineering teams, founders and organisations who:
• Rely on legacy or niche hardware that cannot simply be replaced.
• Need firmware, tools or integrations around existing systems.
• Value clear, low-level documentation and reproducible engineering work.
If that sounds like you, send us a short overview of your projects and what you would like to achieve. High-level ideas are welcome — we can help refine the scope and technical plan with you.
