I'm Kerwin, TS Full-Stack Engineer from China
“A full-stack engineer who’s evolved from 2019’s ‘cut-and-paste’ to 2026’s ‘AI training master,’ hopelessly stuck in TypeScript’s ‘type hell,’ building systems that even AI would call ‘elegant,’ and writing about every late-night debugging session as a joke on the blog.”
My skills
Front-end, back-end, full-stack delivery, and DevOps—plus ongoing writing and sharing.
Front-end
React / Next.js / TypeScript, components, state, performance, and accessibility.
Back-end & API
Node.js services, REST/GraphQL, database modeling, and optimization.
Full-stack delivery
End-to-end from requirements to launch: architecture, APIs, integration, and release.
DevOps & tooling
Docker, CI/CD, monitoring, and logging for stable, traceable iterations.
Technical writing
Blog posts on pitfalls, tradeoffs, and tooling for reflection and sharing.

Who's behind all this great work?
I'm Kerwin, from China, Northeastern University (NEU) grad. Evolved from web dev to front-end to full-stack to TS Full-Stack. I care more about shipping and iterating than stacking buzzwords.
Core kit (NEU edition)
Front-end: responsive layouts done right. Back-end: rock-solid architecture. AI: model fine-tuning, RAG in production, and teaching agents when to shut up.
Writing
I write about real-world pitfalls, architecture tradeoffs, and tooling so I can reflect and hopefully help others.

Career evolution
From 0 to 1 to ∞. Northeastern University (China) grad—built to ship in the cold and in the codebase.

TS Full-Stack Engineer (cyber overlord)
Prompt engineer / Silicon-life shepherd
Code? That’s AI’s job now. Mine is teaching AI to behave: LLM-powered pipelines, “code that writes code.”
If AI replaces my job, it's because I didn't train it well enough.
Full-stack engineer (ascended)
One-person army / Database terminator
Realized that fixing the front alone wasn't enough—had to fix the pipes too. One moment tuning CSS animations, the next writing SQL injection defenses.
Hair density down, sense of control at an all-time high.
Front-end engineer (stubborn edition)
Browser performance squeezer / Vue & React dual cultivator
Northeastern University grad, dove into the front-end deep end. Survived the framework wars and node_modules black holes; stopped obsessing over pixels, started obsessing over components.
First instinct on any webpage: F12.
Web newbie era · "if it runs, ship it" engineer
HTML skeleton / CSS makeup / JS magic (spells in progress)
Simple pages and maintenance—forms, styles, compatibility. Watched console.log go from debug tool to religion.
Why did that div fall down again?
What my clients say
about my work
Feedback and reviews from partners and readers.
Worked with Kerwin on several projects—clear delivery, pragmatic tech choices, and docs that actually get updated. Low-friction collaboration.
