Travel
Going to visit both new & old places –– give me your recommendations! My most recent was a trip to Georgetown, CA. Upcoming is my (annual) trip to Japan in the summer and a year-end backpacking trip to Chile!
Andrew Jansen
Hi, I’m Andrew.
I’m a software engineer from Tokyo, now living in the San Francisco Bay Area. I don't have much of a social media presence, so here's my page dedicated to things I enjoy, stuff I've built, and more generally.. me!
About / 01
A little about me
I'm a half-Japanese/American born and raised in Tokyo living in Berkeley, CA.
There's a lot to appreciate living in the Bay Area, but I find that I spend more time out of the house than in. My days are usually booked up, and I like it that way. When I'm not working my day job, you can usually find me taking a trip, playing games, building & growing things, making music, cooking, and obsessing over green energy, EVs, and personal finance.
Games
Plz invite me to your board game night 😬 I'll play anything! Favorites include some classics – Catan, Splendor, Ticket to Ride – and some more obscure ones like Star Realms, Quantum, and Klank! Big video gamer too – always going back to League of Legends and Overwatch.
Cooking
Dinner tonight brought to you by the NYT Recipes App – with the most helpful comments section in the world. Always looking for easy, weeknight meals sans red meat.
Music
I've been singing for as long as I remember. My current outlet is the Free Key Choir, an Oakland DIY choir, 120 voices strong. Come check us out!
Energy
I find it so fun to think about green energy, batteries, EVs, and how the systems connect. Modern living doesn't have to be bad for the planet!
Money
Personal finance, money management, and planning for my future is fun for me – and I like giving myself something to look forward to in retirement!

Lately
An ever-changing list of what I’m currently spending time on.

Playing In-Person
Clank! Legacy 2 — I'm playing through the campaign with my partner's family, and we're having a blast.
Star Realms Legacy — Its campaign has been a fun supplement to the traditional Star Realms matches I play on the app.

Projects / 03
A few things I’ve built
Two personal projects I’ve been working on.
01Local-first finance
Curei
A macOS portfolio tool that turns inconsistent brokerage exports into one reviewed view of your investments.
AI handles messy extraction and classification. A typed contract, human review, and deterministic code handle the financial data and charts.
- PDF, CSV, and screenshot import
- Snapshot history with safe migrations
- Local storage and explicit privacy boundaries
02Shared expenses
Coukan
A collaborative expense-sharing app for iPhone, macOS, and the web from one Flutter codebase.
The product supports multiple payers, currencies, split methods, payments, and reconciliation without losing a cent to rounding.
- Deterministic multi-currency allocation
- Offline persistence and synchronization
- Private, row-level-authorized group data
Experience / 04
Work, briefly
I build backend systems, but I like product work too: talking through needs, making vague requirements concrete, and keeping people aligned on what to build.

Say hello.
I’m open to backend and product-minded engineering roles. I’m also happy to talk about software, gardens, games, or clean energy.
