About Minchul

I am a Principal Frontend Engineer with 15+ years of experience building scalable front-end architectures, data-intensive UIs, and AI-assisted web applications. I specialize in designing product-ready interfaces for machine learning platforms, BI tools, and enterprise systems.My work spans the full front-end lifecycle. I architect solutions, define MVPs, and iterate quickly using an AI-supported workflow. I regularly use ChatGPT Codex, Gemini, and Copilot to accelerate prototyping, Storybook documentation, unit testing, debugging, and first-pass code reviews. This approach improves delivery speed and ensures consistent engineering quality.I have led major UI modernization efforts, including migrating legacy applications to component-based architectures, building customizable dashboards, creating reusable UI-kit libraries, and improving performance with virtualization and optimized rendering. I collaborate closely with product, design, and backend teams to translate complex requirements into stable, maintainable, and intuitive user experiences. I also have extensive experience working with global, distributed teams.My focus is on building clear, resilient, and intelligent interfaces that help users explore data, create workflows, and use modern AI capabilities effectively.Key SkillsArchitecture and Systems Design, SPA and shell architectures, state management, monorepos, API design, CI/CD, performance optimization, virtualization, DX tooling.Product and Development, MVP workflows, prototyping, Storybook-driven development, testing, code review, engineering standards.Data Visualization and ML Interfaces, dashboards, large-data grids, virtual scrolling, charting, workflow builders, AI chat interfaces.Leadership and Collaboration, cross-functional teamwork, mentorship, UI-kits, documentation, design collaboration.Technologies and ToolsFrontend: React, Angular, Next.js, D3, Plotly.js, Chart.js, Storybook, Tailwind, Fluent UI, TypeScript, Redux, RxJS, SVG, Canvas, WebSockets, Web Workers, SSE, Event Stream/FastAPIAI and Productivity: ChatGPT Codex, Gemini, Copilot.Testing: Vitest, Jest, Playwright, MSW, Nx, Prettier, ESLint, Husky.Backend & Cloud: REST APIs, OpenAPI, OAuth2, OIDC, Docker, Kubernetes, AWS, Azure, Jenkins, GitHub Actions.Design & Data: Figma, Adobe XD, Sketch, Miro, Jira, MySQL, PostgreSQL, Hive.

Experience

1. Principal Frontend Engineer

   Multiscale Ai

   Dec 2024 — Present

   Refactored a legacy front-end into a modern component-based architecture, establishing a shared UI component system that improved maintainability and development consistency.• Upgraded Angular from v16 to v20 and removed all remaining NgModules, simplifying the architecture and reducing technical debt.• Integrated Prettier, ESLint, and Husky pre-commit checks into the CI/CD workflow to automate formatting, enforce coding standards, and prevent low-quality commits from entering the codebase.• Designed and delivered a fully customizable dashboard enabling data scientists and end users to visualize any dataset. This replaced workflows relying on Apache Superset and JMP Chart Builder by consolidating user requirements into a single, unified visualization platform.• Revamped the product’s web UI, including the introduction of modern layouts and dark mode, informed by competitive analysis and current UX/UI trends.• Implemented high-performance data-handling components, such as lazy loading and virtualized row/column scrolling, significantly improving rendering speed, reducing page load time, and enhancing the user experience for large datasets.
