Integrate netfilter, xtables, conntrack and netlink support to in-kernel Lua VM — Lunatik

• Xtable kernel & userspace API: Implemented match and target registration and callback hooks.
• Netfilter API: Support for the new netfilter kernel APIs, ARP and IPv4 hooking symbols in Lunatik.
• Lunatik Improvements: Extended lualinux to handle network-host endian conversion and luadata to handle 8, 16, 32 and 64-bit signed/unsigned data.
• Extras: Fixed critical bugs in lunatik; wrote example scripts, documentation, benchmarks and tests.

Perform static and dynamic analysis; fix and patch bugs upstream into the Kernel

• Device Tree bindings: Converted multiple DTBs to YAMLs for NVIDIA Tegra and USB controllers.
• Kernel standards: Updated device tree sources to replace deprecated ARM GPIO suffixes.
• Debugging ability: Identified and patched a function argument order issue in the BPF subsystem.

Contribute and maintain Apache APISIX Gateway and API7 enterprise products

• NGINX: Developed modules at different NGINX hook phases of Master/Worker process.
• Enterprise: Built support for plugins hot-reload in Control API and cookie-based load-balancing.
• Open-Source: Support for GRPC-web transcoding according to spec and Dubbo-HTTP proxy.
• Internal Tooling: Automated Github Pull Request and Issue tracking using Github APIs.

Build Virtual Desktop Infrastructure backend, streaming server and Linux Infrastructure

• Backend: Built backend and streaming server; optimised it using CPU and memory profiling.
• Reliability: Built a robust and reliable XEvents solution by creating thread-safe CGo bindings.
• Hacking: Hacked a solution for non-standard resolutions in the VDI, serving all device dimensions.
• Linux UAPIs: Support for virtual mouse acceleration and touch using uinput and XEvents in Go.
• Observability: Developed eBPF programs to track OOM killed programs and collect critical logs.
• LLMs in Linux: Developed custom X11 clipboard, keyboard input injection, and utilised X11 API, XEvents & Linux FS API to build an OS Native LLM solution.
