JIAHANG ZHANG / SOFTWARE ENGINEER
I build thoughtful interfaces and the systems behind them. A little craft, a lot of curiosity.
01 — SELECTED WORK / 04
Open-source tools, shared platforms, and a little room to explore.
OPEN SOURCE · REACT / TYPESCRIPT
A virtualized React diff viewer for large text files. Side-by-side reviews, collapsible context, and a focus on rendering performance.
The published component, with generated sample code. Switch layouts or try 10,000 lines.

DEEPSEEK HARNESS ECOSYSTEM
Discover plugins, share reproducible presets, and manage their lifecycle with the open-source Hub CLI.
My work: profile lifecycle management, client tooling, and release workflows.
Review the exact changes before they reach your workspace.
dsh-hub profile diff dsh-web-workspace --version 0.1.0 --profile webCOMMAND WALKTHROUGH · EXAMPLE PRESET
CONTRIBUTOR · DEEPSEEK HARNESS
A coding agent workspace with persistent sessions connecting the terminal, Desktop, scripts, and collaborating agents.
My contributions: Desktop integration, browser isolation, distribution, and credential-scoped balance caching.
Ask a side question without interrupting the main coding conversation.
/btw why is the cache cold on the first turn?COMMAND REFERENCE · RUN IN A DSCODE SESSION
REACT / TYPESCRIPT · VOICE & AI AUDIO
An interactive podcast player with voice interruptions and contextual AI conversations. Ask a question, follow your curiosity, then resume listening from a natural point.
02 — THE PERSON BEHIND THE CODE
THINK IN SYSTEMS.
CARE ABOUT THE DETAILS.
I’m Jiahang, a software engineer focused on frontend architecture and developer platforms. I care about how a product feels, and just as much about how it holds together.
My work connects modular interfaces, reusable capabilities, and the workflows that help teams ship with confidence. React and TypeScript are my everyday tools; systems thinking is the through line.

Clear boundaries. Reusable patterns. Interfaces that stay maintainable as the product and the team grow.
Component architecture · State management · Module FederationBuilding the shared capabilities and internal tools that make everyday engineering work simpler, more consistent, and easier to extend.
CI workflows · Reusable abstractions · Engineering productivityUseful tools should be responsive and easy to adopt. I explore performance-focused UI infrastructure, thoughtful APIs, and practical open source.
Rendering performance · API design · Build in public03 — ALONG THE WAY
Different teams, different challenges.
The same curiosity about making systems better.
Software Engineer
Building the internal platforms that help engineering teams work with less friction.
Full Stack Software Engineer Intern / Co-op
Tools and real-time infrastructure for vehicle testing workflows.
Software Engineering Intern
Making local development simpler and backend services easier to maintain.
Building in public through react-virtualized-diff, DSH Plugin Hub, Aside, and contributions to DSCODE.

B.S. Computer Science
04 — FROM THE NOTEBOOK
Ideas from building interfaces, developer tools, and small experiments. A little space for the thinking behind the work.
Open the notebookINTERFACE ENGINEERING
A ten-thousand-line file is a data problem. The browser only needs to paint a small part of it.
PRODUCT SYSTEMS
What happens to a podcast when a question becomes a conversation? The answer starts with ownership of state.
INTERACTION & CRAFT
A small canvas study, a folding surface, and the decision to stop drawing when nothing is changing.
05 — ROOM TO EXPERIMENT
Small, working studies of form and rendering. Open one, move something, see what changes.
06 — START A CONVERSATION
GOOD THINGS START WITH A HELLO.Frontend architecture, interesting tools,
or a good idea worth exploring.
I’d love to hear about it.
