Software Engineer
In 2014, a kid who dreamed of being a scientist in a white lab coat discovered computers.
I don't believe in limits that haven't been mathematically proven. The harder the problem, the more exciting.
I love breaking through missions that seem impossible and overwhelming.
At 17, I took on a government-funded project—unfamiliar domains,
tight deadlines and resource constraints, everyone thought it was impossible.
Under pressure, I dove deeper into system development, grew alongside my teammates,
secured $33K investment, and built a new project room at Software Meister High School.
Turning black-box unknowns into clear systems is fun.
Limits are just the next thing to break.
History
First software development in elementary school. Built 'FLY', an RPG game about a chicken seeking legendary wings to fly,
competing against other human adventurers who also want to fly.
Researched and validated server systems, JVM internals, and open-source systems.
(Still aspire to be a researcher in a white lab coat.)
School OAuth system, nationwide dormitory management system, 10+ projects developed/operated, early-stage project development, hackathon AWS corporate award, SW-Wave booth operation.
Built a vocational education platform for specialized high schools. Secured 45M KRW investment, funded a new project room at school.
Server Developer at a Vertical AI fintech company. Developed B2B savings bank BaaS model, jvm/k8s observability, tcp performance tuning, and load testing with locust/k6.
Open Source
Argus
A JFR-streaming profiler for JVM 21+ that monitors Virtual Threads (Project Loom) in real-time. Built with lock-free ring buffer architecture for low-overhead event collection. Features WebSocket-based live dashboard for thread lifecycle, GC events, memory allocation, and CPU profiling with automatic correlation analysis.
kar98k
A 24/7 high-intensity traffic simulator written in Go for chaos engineering. Supports HTTP/1.1, HTTP/2, and gRPC protocols with Poisson-distributed spike patterns and micro-fluctuations. Features interactive TUI for configuration, real-time monitoring dashboard, and detailed latency distribution reports (P50/P95/P99).
claude-code-savant
A Claude Code MCP plugin with 5 AI personas for specialized assistance. Einstein explains concepts from first principles, Shakespeare analyzes code with Mermaid flowcharts, Socrates debugs errors with systematic root cause analysis, Steve Jobs provides visionary direction. Smart router auto-selects the best persona for each query.
airML
A lightweight ML runtime that runs ONNX models without Python. Single ~50MB binary with 0.01-0.05s cold start (100x faster than Python). Native Apple Silicon acceleration via CoreML/Metal/Neural Engine. Supports image classification, text embeddings, and model benchmarking with zero dependencies.
Mascot
A lightweight IntelliJ IDEA plugin that displays a customizable mascot in the IDE corner. Published on JetBrains Marketplace. Users can set any local image as their mascot through the Settings UI without rebuilding the plugin. Settings persist across IDE restarts.
cache-labs
A deep-dive study on cache system design with Local Cache + Redis dual-layer architecture. Covers cache consistency strategies, distributed cache design, Circuit Breaker for fault tolerance, monitoring/operations, and high-traffic cache system implementation.
g1-log-capture
A rule-based G1GC log analyzer and tuning advisor. Detects STW pauses exceeding target MaxGCPauseMillis, flags performance-degrading patterns (to-space exhausted, humongous allocations, concurrent mode failure, long remark), and produces actionable tuning suggestions with evidence.
tcp-css-loadtest
A TCP mock server for financial integration load testing. Implements Nice protocol specification with 10-byte length header and EUC-KR encoding. Supports configurable response size (10-14KB), random delays (0.5-2s), and max 100 concurrent sessions for realistic load simulation.
