Sep 2026 – Present

University of British ColumbiaVancouver, BC

Lead weekly tutorials for sections of 30–40 students and support lectures of 100+ on TCP/IP, the OSI model, sockets, and routing; help students debug Java/C socket programming assignments

Jan 2026 – Aug 2026

NETINT Technologies Inc.Burnaby, BC

Designed an automated hardware-recovery subsystem for a fleet of FPGA-based video transcoders (firmware crash detection, DDR memory capture, hardware re-provisioning), refined through senior engineer code review
Achieved 87.5% unattended recovery across 978 regression runs where every hang previously required manual intervention, improving fleet availability and averting cascading false failures (one averted crash preserved 8,000+ queued tests)
Maintained Python/Bash health telemetry tooling (kernel-log scanning for segfaults and driver errors, PCIe drop/rescan, JTAG debug setup), isolating hardware/software faults under concurrent load for faster triage
Extended an object-oriented test framework and built Jenkins CI/CD pipelines (C/C++, Python, Bash, SQL) with hardware and QA stakeholders, validating VPU firmware across 15+ Linux, Windows, and Android configurations

Oct 2023 – Apr 2025

Republic of Korea ArmyDongducheon, South Korea

Led a 5-soldier team in joint U.S.-ROKA operations, safeguarding intelligence under strict encryption protocols

Feb 2026 – Present

GoC++Next.jsWailsGitHub Actions

Developed a Layer 3 virtual network in Go over a P2P transport, migrating from TAP (L2 Ethernet switching) to TUN (L3 IP routing) kernel interfaces to cut per-packet overhead; verified traffic in Wireshark
Hand-wrote a C++ bridge to the P2P transport, loaded from Go via purego (no cgo), and abstracted the TUN device behind a Go interface with platform-specific Linux and Windows implementations
Designed a custom 6-byte IPAM protocol with mutex-locked leasing for dynamic adapter configuration on Windows and Linux; replaced a fixed 1 ms poll with an adaptive read interval to cut idle CPU usage
Built a Wails/Next.js dashboard with live peer status, runtime firewall controls, and Steam friends-list joins
Wrote unit tests across the stack (Go testing, GoogleTest, Vitest) run by GitHub Actions CI on every push; used a Claude Code plan/code/review workflow, reviewing all AI-generated code before merge

PythonFlaskNext.jsSQL

Owned the Flask REST API backend (DAO pattern for isolated SQL) on a team of 4 at nwHacks 2026; loaded OpenAI CLIP once at startup to rank concurrent submissions by cosine similarity

Compete in team CTF events (cryptography, reverse engineering, binary exploitation, web security)
