Open Internet of Things (IoT) device on Raspberry Pi Zero W that captures bird sounds, buffers audio for later classification, and streams data wirelessly for migration studies.

• Designed the Raspberry Pi Zero W stack for audio capture, processing, and wireless delivery in remote installations.
• Automated operating system setup and component integration to keep a robust, field-ready device.
• Collaborated with Smart Open Lab (Fab Lab) to prototype and validate autonomy, storage, and data-sending specifications.

ESP32 (M5Stack) device that captures particulate and gas data from SPS30 and ENVIII sensors, syncs time over NTP, and logs timestamped readings to SD while displaying them locally.

• Implemented sensor integration over I2C for SPS30 particulate matter and ENVIII gas/temperature readings.
• Set up NTP time sync at startup, Wi-Fi disconnect for low power, and SD logging with timestamped records.
• Packaged configurable Wi-Fi credentials via SD-based config to simplify field setup.

Public-facing platform that delivers Graham/Buffett/Lynch-style stock snapshots plus ranked fund and ETF views with no signup.

• Shipped ticker search that surfaces valuation, quality, growth, dividends, and historical return checks in seconds.
• Built fund and ETF explorer that scores instruments by multi-year returns, expense ratio, AUM, and volatility for quick comparison.
• Implemented bilingual EN/ES experience with landing page, FAQ schema, and SEO metadata for better discoverability.
