I am a C# software developer, having written a few libraries/snaps/applications from the projects I'm experimenting on.

My name is Ruhan, curious on how things work (software wise) and a person with deep knowledge on
industrial control protocols, embedded computer hardware and a insiatable itch for diagnosing and fixing problems.

Currently residing in Pretoria, Gauteng, South Africa.

• Have a congenital hearing impairment and wear hearing aids
• Electronics tinkerer
• Leveraging my experience in Linux systems and hardware–software integration, frequently consulted with to advise on custom hardware design and Linux support considerations.
• Highly practical with a strong inclination for DIY problem-solving.

🔭 I’m currently working on:

• CirclePiDeskClock -> CirclePiDeskClock
• Porting Ubuntu-Rockchip for Radxa CM3 -> Links to be added soon
• OpenWRT build for Cambium Force200L-SM unit picked up from previous ISP's installation -> Cambium Force 200L-SM branch
• Experimental patches for the ONVIF protocol on go2rtc for Hikvision DVR/NVR -> My go2rtc fork
• A weekend project doing WiFi packet injection/receiving codec2 compressed audio -> WiFiPacketRadio

🌱 I’m currently learning:

• C/C++
• Some golang
• C# and interfacing between Linux and .NET (Marshaling, P/Invoke)
• Some HTML and JS for basic front-end development
• Bash scripting
• Learning how to use and build custom Linux OS images from kernel sources and using Buildroot or a rootfs, and using RAUC for immutable, recoverable OS updates.

💬 What I achieved/built so far:

• Contributed to SharpSNMPLib -> Added SHA384 and SHA512
• Building a basic kernel module for "boardinfo" -> Boardinfo driver
• Custom, minimal Ubuntu Linux distro called AAR-OS -> AAR-OS
• Ubuntu RootFS bootstrapper for arm64 using chroot -> Bootstrap ARM64 rootfs
• Custom RTC tool using raw i2c transactions to interact with RTC's -> RTCSyncTool
• Customised flashing OS image tool/script (flashOS) -> FlashOS
• RAUC Update bundler script (internal development) -> RAUC Bundler
• Embstar MP05 router module infodump for new OpenWRT builds -> Embstar MP05
• Custom support for Fortinet FAP321C Access point -> OpenWRT for Fortinet FAP321C
• Arduino code for WS2812 LED bow-tie code on ATTiny85 -> StarTie
• Ubuntu Core kernel patch-sets for mainlined 5.10.y and 5.15.y kernels
  • 5.10.y -> Ubuntu Core Apparmor patch 5.10.y
  • 5.15.y -> Ubuntu Core Apparmor patch 5.15.y
• Various Canonical Snap packages
  • minicom snap -> Minicom snap
  • pci-utils and usb-utils snap -> PCIe and USB
  • Linux 'stress' tool snap -> Linux stress
  • Linux 'screen' snap -> Screen snap
  • Old, deprecated raspi-gpio snap (Used for internal testing) -> Raspi-GPIO-snap

✨ What I wish to achieve:

• Contribute more to open-source projects and support the communities with knowledge I have gained from the years, from doing all sorts of work-related projects and personal projects.
