meander & milestones

The source2017 – 2019

Roots

Every river starts as weather. A kid in San Diego taking apart robots at Robolink, writing songs in a garage band, carving a sentence into a school desk that would outlast the desk. Those early obsessions made building feel less like an assignment and more like a habit.

Maker & leader2019 – 2023

Scripps Ranch High

The stream widens and splits around everything at once: engineering electives, robotics club, running a Model UN security council, debate, a newspaper byline, four sports. I learned to keep several channels moving at once and to show up prepared for each one.

Tributaries2019 – 2022

First ventures & service

Side channels feed the river: pitching Silicon Valley investors with GATSVI at fifteen, Red Cross weekends, meal lines with Feeding San Diego, and the first taste of teaching through programming camps and a Berkeley data-science cohort. Service, teaching, and pitching each asked for a different kind of confidence.

The sharp meander2023 – 2026

UC San Diego

A hard bend into engineering. Regents Scholar, computer engineering, and a first year spent soldering for Triton UAS, making PCB layouts in Altium for aircraft that had to actually fly. UCSD gave me room to move between hardware, signals, embedded systems, and computer vision.

The deepening channelApr 2024 – Jun 2025

Voytek Lab

A year and change underwater in neuroscience data: patch-clamp rigs, organoid multi-electrode arrays, and the pipelines that turn electrical noise into signal. I worked close to the recordings, where careful analysis matters as much as the experiment itself.

Concurrent channels2024 – 2025

The braided reach

The river braids: an EEG diagnostic concept one winter, an autonomous car on ROS 2 the next spring, a semi-supervised segmentation ensemble in the fall. Separate channels shared one valley, then rejoined in a broader engineering practice.

A tributary loopFall 2025

DTU, Denmark

A cold, clear detour through Kongens Lyngby: quantum information, databases, deep learning, and computational data science. The exchange widened the frame before I returned to UCSD.

Dark waterJun 2025 – Jun 2026

General Atomics

A year in deep industrial blue: embedded C for a camera driver and control system, optical-controls experiments, hardware that has no patience for almost-working. It was a practical lesson in making systems dependable beyond the bench.

Quickening currentJan 2026

The run-up

The current accelerates: a web data refinery built in a sprint, an embedded-security system hacked together at IEEE HardHacks. Something is about to happen. The pace made the next step feel inevitable.

The built worldApr 2026 – present

Katalyxt AI, San Francisco

The river reaches the city. Four co-founders with a decade of reps behind them raise a pre-seed from NFX, KP Scout and Long Journey, land four design partners, and hit $30K ARR in a one-month sprint. At Katalyxt, I lead product and engineering across the systems that make business knowledge useful to AI.

Distributaries2026

The delta

At the mouth, the river fans out into the replicas of David's Internet, and each distributary ends at a project you can visit or read about. The projects have their own currents now, but they came from the same workbench.

The river doesn't end. It becomes the sea, and the sea becomes weather.
