Daniel Kim

Building reliable, high-scale systems — and the teams that keep them healthy. Ten years in, still allergic to needless complexity.

// About

I like hard problems and boring solutions.

I've spent a decade building the systems people don't think about — payments that don't drop, pipelines that don't lie, platforms other engineers actually enjoy building on. My favorite kind of win is the incident that never happened.

I care about the craft, but more about the outcome: shipping, on-call health, and mentoring engineers into the next tier. I write code that the person maintaining it at 3am will thank me for.

Outside work, I contribute to a couple of open-source data tools and over-engineer my home coffee setup.

// What I do

Where I'm most useful.

01

Product Engineering

Full-stack delivery from idea to production — React/TypeScript front ends on Go and Node services. I ship, measure, and iterate.

02

Platform & Infra

Distributed systems, data pipelines, and the reliability work underneath — observability, scaling, and taming on-call.

03

Technical Leadership

Architecture reviews, mentoring, and turning vague roadmaps into shippable plans. I make teams faster, not just code.

// Selected work

A few systems I'm proud of.

01

Real-time payments platform

Re-architected a monolith into event-driven services, eliminating the nightly reconciliation lag.

02

Developer platform & CI

Built the internal platform 40+ engineers ship on daily — self-serve environments, one-click deploys.

Search & ranking service

Owned the search stack end to end, from indexing pipeline to relevance tuning at 2M+ users.
