Bringup of a MediaTek SoC to a software project along with the kernel, uBoot, target setup.

DMA implementation for a custom MediaTek NAND driver

Eclipse IDE integration for the Equid static analyzer.

Numerous issues in MediaTek SoC were fixed.

Find and fix numerous issues in a commercial WiFi Mesh implementation.

Message broker that can be installed to embedded software and used from Python test suite.

Wristband software was ported to new hardware and gradually improved.

A complete test suite for wristband software based on Robot Framework

Emulator of Bluetooth activity for a consumer electronics device

A complete test suite for the C/C++/Java reversible debugger has been written under my supervision.

Detected, reverse-engineered and eliminated malware in a big project.

Prepared a complete driver for emulating LAN clients.

Prepared cryptography improvements for router software.

SECCOMP mechanism has been ported to older Linux to facilitate LXC integration.

A custom package manager has been coded for a commercial router software. It was based on opkg, but supported many additional features.

A custom OpenVPN solution for Linux-based router software was architected, developed and made available publicly. Partially supports cryptography offloading and packet traffic acceleration.

A complete solution based on LXC has been written for commercial router. It was created with resource constraints in mind, so it actually could provide working containerization on a disk drive smaller than 30MB.

OverlayFS support has been implemented in Linux-based router software package. While the OverlayFS itself is a kernel's feature, a lot of efforts were put into making it supported on a complete solution level, with booting process altered, security, secure erase and other levels sorted out.

The Docker didn't have MIPS support back at that time, but the customer wanted to see it running. I investigated whether it is possible to port Docker (yes, it was), however, we stumbled upon Docker's design implications that prevented us from finishing the project.

Fixed multiple issues in Atheros and Intel (Metalink) WiFi drivers.

A new initial setup wizard was implemented for router software.

Ported DWC2 driver to a new platform, significantly improving stability and performance.

Since we had a host controller driver which was fatally flawed regarding locking, I've made a custom static analyzer to deal with locking problems. It was based on Roslyn patched to support C.

Host Controller Driver used in one of commercial SoCs has been fatally flawed. Fixing it was a major challenge, which required creation of a custom static analyzer.

An L2TP/L2TP+IPSec solution for Linux-based router software was architected, developed and made available publicly. It also works with partial cryptography and packet traffic acceleration.

I've architected and implemented a complete certificate store module for commercial router, which supported certificate/private key generation, import/export, verification against a private key. Still used without major edits (as of 2022).

I've optimized web interface prefetching and loading got 7x performance boost.

I've created a custom DynDNS client that is deployed to thousands of devices worldwide.
