RS-2028CE = Ritvik Singal · class of 2028 · Computer Engineer — in plain terms, an engineer who works across embedded, hardware and AI.
Silicon to agents - I build across the whole stack.

private repo - walkthrough on requestEmbedded engineering on a BLE 6.0 wearable platform at Curafitt: multilayer PCB design, PMIC power and USB-C Li-Ion charging and Zephyr firmware.
Reverse-engineered an RC transmitter by probing 12 potentiometer terminals, then drove all four flight axes from hand gestures: MediaPipe on the host streams landmarks to an ESP32, which injects 12-bit DAC voltages over I²C - with a 500 ms watchdog fail-safe.
Classifies prompts into 4 categories and routes them to the optimal model across 6+ providers, cutting inference costs up to 70% - with streaming chat, automatic failover and RLS auth.
A customized CLI agent for high-performance-computing environments: MCP servers for Slurm job management, documentation Q&A, reporting and Atlassian integration.
Satellite AQI, temperature and humidity fused into a live health score on a 3D city map, with a what-if simulation engine - scenario analysis cut from months to under 4 minutes.
Bullseye - an analog and digital scorer for an archery-style dartboard. Five vibration sensors and a three-stage analog pipeline estimate where the dart landed; an LM339 comparator and a one-hot encoder classify the score, and an 8-bit adder with registers drives a 7-segment display. I led the digital scoring subsystem.
A four-wheel-drive robot steered by hand tilt: a wearable ESP32 reads roll and pitch from a gyroscope, classifies the gesture into forward / back / left / right and sends it to the robot over an RF link (with a Wi-Fi/MQTT fallback), driving an L298N H-bridge across four gear-motor wheels.
