Every layer. Since 1995.
I'm Brian Gunn. For more than 30 years I've built software at every level of the stack: bootloaders and device drivers, embedded Linux, set-top box middleware, Windows applications and cloud web apps. Okopipi Software brings that experience straight to your project.

Capabilities
Full stack, all the way down
When a bug crosses layers, someone has to follow it from the UI down to the hardware and back. That has been my job for three decades.
L6 · Cloud & web
Web applications
Blazor and ASP.NET line-of-business apps, Angular front ends, Node.js REST services and serverless back ends.
L5 · Desktop
Windows applications
Large, data-heavy C#/.NET desktop software, WPF interfaces and SQL Server back ends, plus classic MFC/C++.
L4 · Middleware
Digital video & graphics
Set-top box and PVR middleware, streaming clients, conditional access and graphics stacks tuned for limited memory.
L3 · Operating system
Embedded OS & drivers
Linux kernel modules, Windows NDIS, USB and serial drivers, Bluetooth with BlueZ, and cross-compiled build systems.
L2 · Firmware
Bootloaders & firmware
Bootloaders, BIOS work, secure system upgrade and microcontroller firmware, written in C and assembly.
L1 · Hardware
Bring-up & debugging
Board bring-up, SPI and DSP prototypes, custom PCB design, and reading generated assembly to catch compiler bugs.
Experience · 1995 → 2026
Thirty-one years, to scale
Two consulting firms, an embedded OS vendor, a protocol analyzer maker and a gaming startup, all leading up to Okopipi Software.

About
One engineer, full ownership
Okopipi Software is Brian Gunn, a B.S. Computer Science graduate of Rose-Hulman Institute of Technology with additional coursework in embedded hardware design at UC San Diego Extension.
I work directly with clients, from the first requirements conversation to the last bug fix. Outside client work I build things for the RepRap 3D printer community, contribute fixes to the Haxe and OpenFL open source projects, and design synthesizers for Atmel microcontrollers.
The name comes from the okopipi, the blue poison dart frog of Suriname: small, bright blue with black spots, and hard to overlook.
Let's build it.
Tell me about your project, timeline and the problem in front of you. I'll reply within one business day.
