Projects

Case studies and technical records covering regional data systems, embedded sensing, vehicle validation, and earlier analytical work.

Local Portal dashboard showing regional weather locations and detailed San Jose conditions — **Regional Driving Overview**Weather, route activity, traffic cameras, events, and preparation workflows in one regional interface.

Featured Case Study

Local Driving Intelligence

A regional data platform built for Bay Area and Northern California drivers. It combines weather, route cameras, traffic activity, events, and preparation workflows while keeping the underlying public feeds inspectable.

Stack: React · Node.js · Express · SQLite
Focus: Regional data integration · Route-aware interfaces · Reliability
Current Work: Imagery playback · Provider reliability · Cache behavior · Regional coverage

01 / Purpose

Before the drive

See weather, route activity, cameras, and event details before leaving.

02 / Build

Full-stack system

I built the React interface, Express API, and SQLite data layer.

03 / Reliability

Recent data stays available

Cached results keep the dashboard useful when a public feed fails.

04 / Current Work

More routes and history

Current work adds weather playback and broader Northern California coverage.

Interface Evidence

Regional features in context

Each view connects a public data source or preparation task to the route, location, or event being planned.

Current Systems

Prototypes and ongoing practice

Active work where implementation, evaluation, or field practice is still developing.

02 / Embedded IoTPrototype

Radar + LoRa Traffic Sensor

ESP32 and LoRa sensing node for detecting vehicle activity, generating timestamped events, and transmitting telemetry beyond normal Wi-Fi coverage.

Stack: ESP32 · Radar · LoRa
Direction: Future integration with the Local Driving Intelligence data pipeline

03 / RoboticsPrototype

Vehicle Proximity System

ESP32 and ultra-wideband ranging system for measuring vehicle spacing and presenting driver-facing feedback during closed-course tandem driving.

Stack: ESP32 · UWB · Driver feedback
Focus: Ranging, calibration, filtering, mounting, and driver workload

04 / MotorsportsOngoing Practice

Performance Driving & Validation

Telemetry, instrumented driving, and structured session review across drifting, autocross, track driving, and simulation.

Focus: Vehicle dynamics · Telemetry · Validation
Method: Repeatable comparisons of sessions, setup changes, and driving techniques

Earlier Work

Academic projects
