Full-stack engineer building robot-operations products end to end — UI, APIs, data flow, ROS2 interfaces, deployment, and on-site operations documentation as one product thread.

Seoul / Incheon, South Korea · English (working proficiency) · Korean (native) · Japanese (intermediate)

Highlights#

  • Robot fleet console from the ground up. Led the initial structure and core feature design of ARC Fleet's operations console at ARICA, implementing both frontend and backend.
  • Field-proven ROS2 operation. Tuned Nav2 bringup, docking/undock, elevator board-and-alight actions, keepout and narrow-mode filters, and 3D-LiDAR-to-2D-scan pipelines during the Pyeongchang deployment.
  • Self-hosted infrastructure. Migrated my own services from AWS to a self-operated server stack (Docker Compose + Caddy + Cloudflare Tunnel + PostgreSQL) in 2026-04.

Experience#

Robotics Engineer — ARICA (Aug 2025 – Present)#

ARC Fleet — Multi-Robot Fleet Operations Platform (Jan 2026 – Present) A unified console handling projects, robots, groups, models, and maps for real field operations.

  • Led initial structure and core feature design; implemented both frontend and backend.
  • Shipped real-time monitoring, remote control, map editor with calibration and layer management, command history, and deployment-status indicators.
  • Introduced operational guardrails (delete confirmations, unsaved-change guards, primary-map change warnings) so field operators cannot trigger destructive actions by accident.
  • Stack: React, TypeScript, NestJS, MongoDB, Socket.IO, MQTT.

Pyeongchang Youth Training Center — Robot Operations & Content Platform (Aug 2025 – Jan 2026) On-site deployment for guide, delivery, and patrol robots.

  • Built the admin operations console (Next.js 14): real-time alerts, robot position interpolation, patrol image modal, map editing UI.
  • Built the content-management web: statistics APIs, dual standby screens (main hall / residence hall), content upload, TTS and email integrations.
  • Built an Express-based ops server covering robots, environments, schedules, commands, reports, alerts — with WebSocket and Kafka integration.
  • Owned deployment scripts, nginx, certificates, ZIP upload + versioning + S3 deployment workflow, and wrote incident runbooks for redundant-server failures.

Neubie delivery-robot driving operations (within the Pyeongchang project) Nav2 bringup tuning, keepout filter and narrow-mode tuning, docking/undock, elevator board/alight actions, 3D LiDAR → 2D scan pipeline checks, TF and scan-rate tuning for driving stability and CPU load.

RobotApp Web — Browser-based ROS2 Operations Tool (H2 2025 – Present) FastAPI + WebSocket + rclpy gateway bridging ROS2 DDS to the browser without rosbridge. React + Three.js + Konva UI for 3D viewer, 2D map editor, remote control, parameter upload, map save, E-STOP.

Backend Engineer — RODI (Jul 2023 – Apr 2024)#

  • Python backend for a multi-marketplace product management system.
  • Unified marketplace authentication and data structures (Coupang, SmartStore, 11st) using the adapter pattern.
  • Connected crawling ETL with upload automation to improve ops efficiency.

Platform Planning & Automation — GCI / Senior Village (Mar 2023 – Present)#

  • Planned service flow and content UX for a senior-focused community platform.
  • Built content collection / processing / upload automation pipelines with Python, Selenium, and Gemini.
  • Site: seniorvillage.co.kr

Personal Products#

  • IchiMozzi (2024) — AI-assisted JLPT study app. Designed and built the mobile UX, backend APIs, per-user learning data, study logs, and wrong-answer notebook. Play Store. See also side-projects overview.
  • OpenAkashic (2026 – Present) — Visibility-aware knowledge network running on a self-hosted stack. → Details.

Education#

  • Hankuk University of Foreign Studies — Japanese Language & Culture / Cultural Arts Management, bachelor coursework completed (graduation deferred), 2016 – 2025.
  • Addinedu — Advanced ROS2 & AI Autonomous-Driving / Robot-Arm Developer Bootcamp, Mar – Jun 2025 (Best Team Award, RoboDine).

Skills#

  • Frontend: React, Next.js, TypeScript, Tailwind, Zustand, TanStack Query, Three.js, Konva
  • Backend: NestJS, Express, FastAPI, MongoDB, PostgreSQL, WebSocket, Socket.IO
  • Robotics / Realtime: ROS2, Navigation2, rclpy, Kafka, MQTT, costmap / keepout tuning, docking & elevator actions
  • Infra: Docker, AWS (S3 / EC2 / RDS), Caddy, Cloudflare Tunnel, nginx, GitHub Actions
  • Languages: Korean (native), English (working), Japanese (intermediate)
