Matthew Lin

I build systems that serve people — and somewhere along the way, engineering, storytelling, and curiosity became the same pursuit.

module::philosophy

Two voices

src/identity/philosophy.md
$ cat philosophy.md

Software engineer with 3+ years building scalable full-stack and internal tooling systems. Experienced in experimentation frameworks, analytics instrumentation, and product-driven engineering. Currently focused on scaling AI products to reach broader audiences.
The best systems I've built started with understanding people — their frustrations, their workflows, their unspoken needs. Code is just the language I use to respond.
The best software disappears into usefulness. Design principle

module::history

The arc of a system

logs/career.log — build history
Every career is a story told in fragments — commit messages and late nights, refactors and revelations.
September 2023 — Present (2y 5mo)
Software Development Engineer
$ org --name "Amazon"
Designing AI workflows, building memory-bank review systems, shipping notification systems to 500K+ customers. Leading internal tooling used by 20+ teams.
July 2021 — September 2022 (1y 2mo)
Software Engineer (Full Stack)
$ org --name "Brevy (YC S20)"
Built OAuth integrations, onboarding flows, and analytics instrumentation. First experience with the pace and ambiguity of early-stage startups.
September 2024 — August 2025 (11mo)
Research Assistant
$ org --name "Cal Poly Psychology Department"
Social psychology research. Understanding human systems through academic methodology.
November 2020 — December 2021 (1y 1mo)
Educational Content Creator
$ org --name "YouTube"
Created 100+ educational videos, built an audience of 300+ subscribers. Learned that teaching is a form of engineering — structuring knowledge for consumption.
2018
System Initialized
$ event --type "origin"
First line of code. The beginning of a long conversation with machines.
module::capabilities

The tools I reach for

config/capabilities.json — runtime skills
React / TypeScript / Next.js for building interfaces that feel alive. Node.js / Java / Python for systems that think clearly. AWS / ECS / Lambda / Docker for infrastructure that scales. DynamoDB / MongoDB / PostgreSQL for data at rest and in motion. Agentic AI / System Design / Spec Engineering for the systems of tomorrow. React Native / Swift when the platform changes shape. Express / NestJS for the architecture underneath.
Every system I build — technical or personal — is an attempt to better understand how people grow, connect, and create meaning over time. Personal reflection
[human.layer] personal modules available
There's more to a person than their deployments. Below is the quiet room inside the same architecture — writing, curiosity, and the things that don't fit in a résumé.

Beyond the terminal

I build systems to solve real problems, but the work that matters most to me is understanding the people those systems serve.

Things I make

signal::builder

What I build outside work

The best engineers treat their own life like a system — iterating, testing, refactoring — always in service of something better.
$ ls ~/projects/personal

Personal knowledge systems, AI-native productivity workflows, experimental applications. Exploring emerging engineering patterns and building side projects primarily for learning and curiosity.
There's something honest about building things nobody asked for. Side projects are where I learn to think differently — where the stakes are just curiosity and craft.
signal::growth

How I grow

Early mornings and long walks to clear the head. Journaling and reflection for the mind. Structured daily routines for the trajectory. Taiwanese heritage and language learning for perspective. Indie, R&B, and Asian pop for the mood. Fiction and narrative-driven books for new worlds.
signal::curiosity

Currently exploring

active AI-native software development workflows
active Organizational psychology and human systems
active Systems thinking and decision frameworks
active Storytelling as a tool for understanding people
active Language learning and cross-cultural communication
