Build log

Projects

A running record of things built, from a competition UGV down to a Raspberry Pi clinometer.

Featured builds

Solo, an autonomous ground vehicle, navigating an obstacle course

Solo

An autonomous unmanned ground vehicle built with Project Manas for the Intelligent Ground Vehicle Competition (IGVC) at Oakland University. Helped win IGVC 2019 and several other awards.

Real-time vein visualization output from SAMIS

SAMIS

A smartphone-based vein-imaging system that uses visible-spectrum image processing to visualize subcutaneous veins without IR hardware, aimed at making IV access easier for nurses. Won Second Place Grand Award in Biomedical Engineering at Intel ISEF 2017 and the Grand Award at IRIS 2016.

Magniwear AR/VR microscope headset

Magniwear

An AR/VR microscope on the Google Cardboard platform, operated hands-free by voice while exploring biological samples, doubling as a dental loupe and a live-streaming tool for remote guidance. Selected top 90 globally, Google Science Fair 2015.

Illustrative conversation trace: user and agent speech envelopes, a barge-in where the agent yields, and an ASR/LLM/TTS latency budget

ProxyTalk

A real-time voice-agent platform: a streaming ASR → LLM → TTS pipeline over SIP/WebSocket with VAD, turn-taking, and barge-in, built on the OpenAI APIs. Sub-1,000ms p95 end-to-end latency.

Software & tools

IntelliDetect GUI showing training statistics

IntelliDetect

A Qt/C++ GUI and neural-network library for training and deploying networks from a config file, with training statistics, visualizations, and inference built in.

Illustrative group tree: nested GitLab groups expanded to repositories, each marked cloned, pulled or skipped, with a run summary

CloneLab

A CLI tool that clones and pulls updates for every repo in a GitLab group at once, since GitLab has no native way to do that.

Illustrative tracking figure: noisy measurements, Kalman-filtered tracks with covariance gates, and one track coasting through an occlusion

ObjectTracker

A Kalman-filter based tracking module for pre-segmented objects in video, handling objects moving in and out of frame and tolerating positional noise.

Illustrative topic-modelling figure: per-topic term weight bars beside a document of sentence blocks shaded by dominant topic, five selected as the summary

DocumentSummarizer

A reusable Python library for unsupervised topic modelling (LDA) combined with extractive summarisation.

Illustrative forecast figure: ambient temperature crossing a heatwave threshold, with a wearable heart-rate lane showing an adverse response and an alert dispatch

Torrid

Heatwave prediction and notification: tracks weather data to predict onset, and can detect an adverse response in the user's body via a wearable and call for help automatically.

Illustrative patient-flow figure: anonymous patients moving through hospital department lanes over time, with the paper forms the app replaces listed underneath

Dental Assessment App

An iOS app to digitize treatment history, appointments, and department visits for a local dental hospital, built as a final project for an iOS course.

Hardware

BreatheSafe indoor air quality monitor

BreatheSafe

A low-cost indoor air-quality monitor using an Arduino Uno and an MQ-35 sensor to track CO2 and VOC levels. Won a model-making competition at St. Aloysius College, Mangalore.

Robaldo soccer-playing robot

Robaldo 2016 bot

A Bluetooth-controlled soccer-playing bot built from scratch for the Robo Soccer Challenge at PESIT University against 68 teams — reached the quarterfinals.

Digital clinometer device

Digital Clinometer

A Raspberry Pi device that measures building heights using an ultrasonic sensor and an MPU-6050 accelerometer/gyroscope — the first project I ever built, in 10th grade.
