HEMASHREE, Software Engineer. B.Tech Computer Science Engineering at VIT Chennai. Building systems that see, decide and keep people safe.

LinkedIn Portfolio Email

B.Tech CSE at VIT Chennai Location Open to opportunities Patent co-inventor

01 About: Hello, I'm Hemashree.

Animated terminal: whoami, Hemashree, software engineer. Education: B.Tech Computer Science Engineering at VIT Chennai. Focus: vision, reinforcement learning, embedded, security. Patents: smart walker, sensor-fusion fall-risk prediction (filing in progress). Open to cybersecurity, computer vision, cyber-physical systems, backend and DevOps. Languages: Tamil, English, Hindi, Japanese.

Right now: shipped 3 deep dives on SeatLock, RootLens and TriageIQ; backend and DevOps, concurrency and incident response; learning binary search trees in Java and solving LeetCode daily; starting Pit Wall, an F1 race replay built on real GPS data. Quick facts: co-inventor on a smart walker patent (filing in progress); went to Singapore for NUS Industry 4.0 and SuperAI 2025; 31 dental conditions detected on 13,000+ X-rays; speaks Tamil, English, Hindi and Japanese; Design Lead by night.

02 Philosophy: How I think about problems.

Sense, Decide, Protect: a closed feedback loop. Sense with X-rays, IMUs, load cells, pose estimation and sensors. Decide with YOLOv9, Q-learning, CNNs, risk scoring and fusion. Protect with fall alerts, hazard maps and automated IDS responses.

03 Journey: The road so far.

Timeline: VIT Chennai Aug 2023; research intern May to Jul 2025; Singapore, NUS Industry 4.0, SuperAI and IBM Gen AI Jun 2025; dental X-ray AI with YOLOv9 on 13,000+ images Jul to Sep 2025; patent co-inventor 2025 to 26; backend and DevOps 2026 with SeatLock, RootLens and TriageIQ; now building 4 more projects.

04 Selected work: Things I've built.

Dental Malocclusion Detection: YOLOv9 pipeline detecting 31 dental conditions on 13,000+ X-rays (test mAP@50 38.7%), with per-finding HiResCAM explanations, an FDI tooth chart, a Gradio app and PDF reports.

Dental Malocclusion Detection repository

SeatLock: a ticket-booking backend where thousands of buyers race for one seat and nobody gets double-booked. Three locking strategies, version fencing and a partial unique index; a Kafka payment saga with a transactional outbox; a Redis waiting room. 200 threads race for one seat and exactly one wins; k6 finds zero double-bookings; 2,171 requests per second with fast reject. Java 21, Spring Boot, PostgreSQL, Redis, Kafka, k6, Testcontainers.

SeatLock repository

RootLens: an incident-response lab that detects a failing microservice, investigates the cause, decides on a fix within strict limits, rolls back the bad release and verifies recovery, with an audit log of every decision. A real incident went from open to resolved in under 2 minutes; 118 unit tests.

RootLens repository

TriageIQ: an AI support inbox that runs fully on-device. Emails flow through Kafka, a local 3B model classifies them with a safe fallback, RAG over solved tickets drafts a grounded reply, and a human approves every reply before it is sent.

TriageIQ repository

GitLoom: type a GitHub username and it reads the public repos, languages and activity in the browser, then weaves them into a portfolio website in a live studio. Ten templates, one HTML file to host free, no servers or sign-ups. JavaScript, HTML, CSS, GitHub REST API, GitHub Pages.

GitLoom demo: the landing page loom weaves a row for every letter typed, then the studio switches between templates. Click to watch the full 1-minute demo with narration.

Smart Walker (patent, filing in progress): co-invented IoT walker that predicts fall risk using dual IMUs and load cells with sensor fusion; runs standalone on Arduino for under USD 30.

RL Rover for Hazard Detection: a simulated rover that learns to explore a disaster area and discovers hazards through perception, using tabular Q-learning, a lightweight CNN and a 4-way reward ablation.

RL Rover repository

Smart Grocer: multimodal fresh-produce spoilage detection, item localization and expiry-aware retail inventory management.

Smart Grocer repository

More projects: Intrusion Detection and Threat Modeling, a behavioral IDS for a simulated bank; Jarvis, an offline privacy-friendly voice assistant.

05 In progress: Currently building.

Currently building: Pulse, a free status page on GitHub Actions and Pages (step 1 of 5); PortPilot, find and free busy ports (planned); BST Playground, animated binary search trees (planned); Pit Wall, F1 race replays (planned); LeetCode Solutions in Java (daily).

Pulse PortPilot BST Playground Pit Wall LeetCode Solutions

🤫 Things you won't find on my résumé
  • 🏎️ I'm an F1 fan, which is why I'm building a race-replay app on real GPS data.
  • 🎨 I design posters and creatives as Design Lead, so I care how things look, not just how they work.
  • 🗾 I can say よろしくお願いします, and mean it.
  • 🛠️ I'm building PortPilot because a Kafka container once stole my port 9092.
