Software Engineer & Open-Source Contributor
Reliable AI systems.
Practical software. Open-source work.
I'm Ruikang Wang, an incoming M.S. student in Artificial Intelligence at Columbia University, beginning Fall 2026.
I build developer tools and production software, with current interests in agentic coding infrastructure, context engineering, and LLM reliability.
I work at the intersection of software engineering and applied AI.
My recent work includes reliability improvements to open-source developer tooling and a real-time Windows desktop system involving persistent state, low-latency UI, automated releases, package verification, and rollback support.
beads
Reliability improvements for structured task memory.
Fixed sync-branch diagnostics so database and modification-time checks use the active worktree JSONL source, eliminating false divergence warnings. Added regression tests.
antigravity-proxy
Routing and configuration improvements for a Windows networking tool.
Added rule-based routing and a web configuration interface.
Bomana
Video game companion and desktop overlay.
Bomana is a Windows video game project built around official in-game status data and focused on a practical desktop overlay experience.
The engineering work includes persistent state recovery, low-latency overlay UI, multi-monitor behavior, hotkey control, update packaging, integrity verification, release automation, and rollback support.
Game boundary: uses documented local game status endpoints only; no process-memory access, code injection, or hidden-opponent data.
SiguaArmor
Browser-native 3D armor analysis platform.
SiguaArmor turns a curated vehicle catalog into an interactive viewer for exterior models, internal components, protection maps, penetration paths, and damage analysis.
The architecture combines content-addressed Editor-derived asset packs, GPU rendering, Worker-isolated BVH and rules computation, lazy per-vehicle delivery, and contract-driven quality gates.
Source boundary: official promotion data defines catalog scope; attributed third-party references are never presented as official game data.
