hey, i'm hari
ece undergrad at new horizon college of engineering, bangalore (2023–2027). i build real-time data systems, mobile apps, and ml pipelines — things that are fast, reliable, and actually useful.
interned at drdo cair working on nlp for defense document retrieval. previously built a fraud detection system, a self-hosted media cloud, and a maternal healthcare platform with clinicians from ramaiah medical college.
i like working close to the metal — kafka, docker, go backends, flutter frontends. if it moves data fast or runs on a phone, i'm interested.
experience
ml intern · drdo cair
centre for artificial intelligence and robotics, bangalore
built an nlp-powered document recommendation engine over 5,200+ defense documents using spacy and tf-idf vectorization. achieved 0.79 cosine similarity score for top-k retrieval and reduced false positives by 15% via comparative analysis of cosine vs. jaccard similarity algorithms.
projects
python · kafka · xgboost · docker · postgresql · redis
end-to-end pipeline processing 590k+ transactions. xgboost classifier at 96.6% auc on a 1:27 imbalanced dataset using smote and threshold optimization. redis caching cut feature lookup latency by 40%, sustaining 670 tps. grafana dashboard tracking inference at <50ms p95.
flutter · go · nginx · ffmpeg
self-hosted, privacy-first google photos alternative. custom go backend for low-level filesystem access. nginx serves static assets directly from disk — sub-50ms load times. ffmpeg workers transcode avi/mkv and generate webp thumbnails in the background. flutter client with fault-tolerant uploads and infinite scroll.
flutter · zegocloud · firestore · dart
maternal healthcare platform built with tropical medicine specialists and pg clinicians from ramaiah medical college. clinical triage protocols translated into stepwise patient assessment flows. hipaa-compliant video consultations via zegocloud webrtc at <200ms latency. anonymous test kit ordering with qr verification.
