Software Craftsmanship

About us

SIGDEV is a young company providing efficient and high quality software engineering services. We specialise in systems-level and embedded programming, using languages such as C, C++ and Python.

What we do

What we can do for you

Systems Development

Our expertise is in low-level development and applications needing maximum efficiency. We've worked extensively with languages such as C and C++, and developed applications that interact closely with the Linux kernel.

Software Architecture

Software needs to be carefully designed, particularly at scale. We can advise on and implement improvements to your system architecture, to reduce bugs and to improve developer productivity.

Clarity & Simplicity

Code needs to be clear, well-tested and well documented to ensure long-term maintenability. We focus on providing software that is easy to understand, maintainable and correct.
