Turning workflow friction into systems

Smilegate RPG

Hi there 👋I'm Junyoung Park.

Dev Productivity / Tooling Engineer

I design and build tools and systems that improve the productivity of engineering teams and end users. For 9+ years, I've been identifying inefficiencies in workflows and turning them into tools, automation, and platforms.

About

Rather than a feature developer in a specific domain, I'm an engineer who designs and implements tools and systems that enhance productivity for development teams and end users. From DRC systems in the EDA/PCB domain to CI/CD pipelines, AI code review PoCs, and onboarding automation — I design tools that fit real usage flows and complete them at production-ready quality.

  • Deployed a Gitea-based internal AI tool marketplace serving 70 engineers with a self-service AI tooling platform

CI/CD Pipeline & Deployment Automation

  • Previous team: Analyzed and restructured scattered build jobs across the org into an organized TeamCity build chain
  • Current team: Designed and built the entire operational program deployment process from scratch, automating end-to-end delivery

AI-based Code Review PoC

  • Developed a multi-model code review app supporting OpenAI, Claude, and Gemini with easy model switching
  • PoC findings served as concrete evidence in the decision to adopt Perforce Swarm as the team's code review tool

Slack-based New Hire Onboarding Automation

  • Integrated Slack Workflow with internal systems to automate new-hire guidance, initial development environment setup, and Perforce account provisioning
  • Built a single-action workflow that starts the entire onboarding process when a new employee is invited to a designated Slack channel
  • Standardized previously manual account and environment setup, reducing repetitive work and setup omissions

Internal Tooling System

  • Delivered tools as WPF desktop apps, CLI tools, and VSIX extensions based on usage context
  • Reduced friction across workflows, contributing to organizational productivity gains

Perforce & Hansoft MCP Plugin Development

  • Built a full-coverage Perforce MCP plugin supporting all P4 commands, giving AI agents complete access to source control
