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

2014. Junior (real jr. age lol)

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.

Software Meister High School (CSE). 2022. ~ 2024. ↗

Researched and validated server systems, JVM internals, and open-source systems.
(Still aspire to be a researcher in a white lab coat.)

10+ Projects. ↗

School OAuth system, nationwide dormitory management system, 10+ projects developed/operated, early-stage project development, hackathon AWS corporate award, SW-Wave booth operation.

Government Project. 2023. 09 ~ 2024. 11 ↗

Built a vocational education platform for specialized high schools. Secured 45M KRW investment, funded a new project room at school.

HonestAI. 2024. Dec ~ Now ↗

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

JavaCLIWeb DashboardJFRasync-profilerSpring Boot

Open-source JVM observability platform that unifies jcmd, JFR, and async-profiler. 33 CLI commands and a real-time web dashboard — both provide heap analysis, thread dumps, GC monitoring, flame graphs, and virtual thread tracking. Attaches to any running JVM (Java 11+) without an agent. Prometheus/OTLP export, Micrometer bridge, and Spring Boot starter included.

kar98k

GoHTTP/2gRPCTUIPrometheusPoisson

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

Claude CodenpmMulti-AgentOrchestrationTUI

A Claude Code harness that orchestrates multi-agent teams modeled after real engineering orgs. Auto-dispatches hierarchy (CTO → Lead → Senior → Junior) or squad (flat parallel) compositions based on task complexity. 14 specialist roles, 49 domain agents, anti-hallucination controls (file grounding, typecheck, scope lock), and session observability TUI with loop detection and productivity scoring.
