Five overlapping crafts, one way of thinking
The same instinct runs through all of it: find the friction, model the problem, and build something clean.
Product Design
Framing the real problem, shaping the flow, and shipping something people actually use.
UX/UI Design
Research, wireframes, prototypes, and clean interfaces backed by a real design system.
Python
Scripts, automations, and backends that take the tedious parts off people's plates.
Data Engineering
Modeling, cleaning, and moving data so the numbers can be trusted and queried.
AI/ML
Practical LLM apps and agents that assist real workflows - grounded, not gimmicky.

Real problems, shipped solutions
VZTR Help
Hospital visit coordination that respects the patient’s energy — not the group chat.
VZTR Help started as a real problem I lived through as a primary caregiver during the COVID era — then became my UC Berkeley UX/UI capstone, where I pitched the concept, led our team, and mapped patient and visitor flows end to end. Today it is a deployed MVP on the path to hospital-grade visitor coordination: one link, clear rules, no double-booking, and rest when the patient needs quiet.
Petchmaker
When you can no longer care for your pet, find it the right person.
A matching platform connecting pet owners who need temporary or permanent care with vetted caretakers - profiles, listings, and a request flow that respects how emotional these decisions are.
Code Coach
An AI study partner that coaches instead of just answering.
A web app that helps people learning to code by coaching them through problems - asking guiding questions, hinting, and explaining - rather than handing over copy-paste answers.
Resume / Job Matcher
Score a resume against a job description - and name the gaps.
A focused Python tool that scores how well a resume matches a job description and, more usefully, lists which of the job's important keywords are covered and which are missing.
