Hope Kim @rlaope
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.
Art & Engineering.
I believe true innovation is born from the fusion of deep engineering thinking and beautiful artistic thinking.
That's why I love aesthetically beautiful things like art and fashion.
I have a hobby for clothing and anything that delivers visual satisfaction.
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, Netty system bottleneck analysis/improvement, and load testing with locust/k6.
Projects
Argus
Lightweight JVM diagnostic toolkit. 50+ CLI commands and a real-time web dashboard — heap analysis, thread dumps, GC monitoring, flame graphs, virtual thread tracking, k9s-style interactive TUI, health diagnosis, CI/CD gate, and slow method detection. No agent required for CLI. Prometheus/OTLP export, Micrometer bridge, Spring Boot starter, Docker and GitHub Actions support.
kar98k
Open-source 24/7 traffic simulation and performance testing SDK in Go. Generates realistic traffic with Poisson-distributed spikes, time-of-day scheduling, and micro-fluctuations instead of flat constant load. Supports HTTP/1.1, HTTP/2, gRPC with interactive TUI, adaptive TPS discovery, and Prometheus metrics.
bestwork-agent
Harness engineering for Claude Code. 7 automated quality gates (grounding, scope lock, strict mode, type check, review, requirement check, validate) catch hallucinations, platform mismatches, and security flaws — 100% catch rate in benchmark. Smart gateway auto-dispatches Solo/Pair/Trio/Hierarchy/Squad teams. 49 domain agents, 22 skills, session observability TUI, and Discord/Slack notifications.
Contributes
Fix mmap failure check and munmap size in OS::copyFile on macOS
Simplify ServerRequestExtensions.queryParamOrNull()
Use idiomatic Kotlin in Map Health Indicators to Micrometer Metrics example
Improve BatchMessagingMessageConverter toMessage() implementation
Fix syntax errors in link formatting in adoc files
Change method return condition for connectionFactory.isPublisherConfirms()
Improve functional logic in SQL Statement classes
Update FlowResponseConverterFunctionProvider type extension toClass()
Support arithmetic function CEILING
Improve auto-completion with table prioritization and horizontal scrolling
