SPENCER
TONG
Recent CS grad shipping code at a financial firm in Boston. Early in my journey and leaning all the way in — learning to build products end to end, take real ownership, and write about what I pick up along the way.
Fresh to the field.
Learning fast.
I graduated from Rutgers in 2025 with a degree in Computer Science and Mathematics and went straight into a full-time engineering role at Brown Brothers Harriman in Boston, where I work on enterprise backend systems — workflow automation, distributed data pipelines, and production database infrastructure.
I'm early in my career and I lean into it: I ask a lot of questions, move fast, and try to leave things better than I found them. What matters most to me isn't the stack — it's being around people who are genuinely curious and have a real sense of ownership in their work.
On the side, I'm also working as an independent contractor for a more experienced builder — equal parts apprenticeship and proving ground. I'm learning to ship products end to end and own real outcomes, not just the software in the middle.
Outside of work I'm usually at the gym, running, playing guitar, or picking up a book. Recently I ran my first marathon and have been volunteering when I can.

Things I've built
Slatebell
A live legal-tech SaaS that helps Massachusetts renters recover illegally-withheld security deposits: a free instant analysis of the statutory violations in their case, and a paid Dispute Kit that generates a legally-grounded demand letter and sends it via certified mail.

Things I've written
Building a Tiny Identity Graph to Understand a Big One→
Prepping to interview at Semcasting, a data-as-a-service identity resolution company, I built a small Python ETL pipeline that does a deterministic matchback - the core of ad attribution - end to end with Snowflake. Here's the concepts and the build, with a video walkthrough.
Company Spotlightsgo ahead and ask dad one more time about when he was your age→
I designed, built, and shipped a memory journaling app to the App Store by myself - Banyan. Here's what it does, the parts that were way harder than they looked (offline-first sync, real permissions, App Store-compliant account deletion), and what owning the whole thing taught me.
Miscwhat's this funnel's recovery score?→
WHOOP built a beautiful membership page that quietly makes you do too much work to buy. Here's the one conversion experiment I'd run first, with a live A/B demo you can toggle yourself.
