Frontend Engineer · Tech Lead
Stone Chen 陳絲彤
Frontend engineer turned product-minded tech lead. I build products a million people use every day, shape what gets built, and lead the team that ships it faster.

- +50%dev efficiency after AI-assisted development and automation
- 1 monthfrom requirements to go-live, medical AI

Selected work
Three projects that show how I work.
Of 400 features, keeping the two that earn the most rock-solid.
Led the fund and FX modules of a million-user online bank: top 10 by traffic, 93% of revenue. Shipped every month under banking regulation without trading speed for quality.
View case →Turning what physicians asked for into a system live within a month.
As TPM, translated clinical needs into specs with clinicians, data analysts and engineers. Report time down 60%; physicians save about 20% of their day.
View case →Getting a codebase to the point where AI can safely take the wheel.
Spec-first development skill, mock server, CI checks, an n8n team knowledge base and a Claude Design System: what AI writes has a spec to match and a gate to pass. Dev efficiency +50%.

How I work
What happens off-screen.
- 01
Spec first
Spec and demo agreed before build, API contracts before frontend, mock server before backend.
- 02
Leading a team of 5–8
Standups, an onboarding handbook, a component library and Storybook so new joiners ship in week one.
- 03
AI-assisted development
AI in review, layout and the knowledge base, not just in writing code.
- 04
Performance and quality
Web Vitals, Lighthouse, and the caution you learn from being on call.
Side projects
Still trying new things after hours.
Path
From advertising to medical AI.
