ArbFlow
Multi-tenant GA4 analytics SaaS — secure workspaces, per-tenant data isolation, and a clean dashboard for product metrics. Deployed and running in production.
I ship across applied ML and full-stack SaaS — from healthcare biosignals to multi-tenant analytics in production. I like turning ambiguous problems into things that run.

Automated training pipeline that detects failures and recovers without manual intervention — retraining, rollback, and alerting built in.
Models don't fail loudly — they rot. Inputs drift away from the training distribution and accuracy slips for weeks before anyone notices. I built this so the pipeline watches its own data, catches drift statistically, and retrains itself before degradation ever reaches users — making reliability a property of the system instead of a fire drill.
A 1D CNN that detects apnea events from single-lead physiological signals, validated with leave-one-patient-out cross-validation so results hold on unseen patients.
Apnea events are rare, so accuracy is the wrong yardstick — a model can score ~91% by mostly predicting 'normal' and still miss the events that matter. I evaluate it on recall/sensitivity and PR-AUC over the apnea class, where real performance actually shows. Catching that gap and rebuilding the evaluation around it is the core of the paper I'm writing.
Predicts pre-eclampsia risk from routine clinical features — one of the leading causes of maternal mortality worldwide. Built to flag high-risk pregnancies early enough for intervention to change the outcome.
Pre-eclampsia is one of the leading causes of maternal death, and the hard part is that it's often catchable — the signal sits in routine checkup data well before it becomes an emergency. I built this to surface that risk early, from features clinicians already collect, so intervention can happen while it still changes the outcome.
About
I ship. Most of what I'm proud of started as a vague problem and ended as something running in front of real users.
My work spans two worlds — healthcare biosignals and product analytics. One day it's a CNN reading single-lead physiological data; the next it's per-tenant isolation in an analytics SaaS. The throughline is the same: turn a hard, real-world problem into a working system people rely on.
I gravitate to early-stage teams where shipping is the job. ArbFlow is what I'm building now, and my sleep-apnea paper is in progress.

Field notes
No grand process — just a loop I trust: figure out what actually matters, ship the smallest real thing, put it in front of people, and tighten it from there.

Same way I like shipping — line it up, make clean contact, send it.

I'm looking for SWE internships with early-stage teams. If you think I can help you ship, I'd love to hear from you.
