HemashreeVI/README.md
Cinematic intro. A terminal boots: booting hemashree.exe, loading projects SeatLock, RootLens and TriageIQ, mounting patents smart-walker and hazard-rover, linking channel Byte Decoded, status open to work. A glitch cuts to a rainy neon city at night with a striped moon, flying cars and neon signs reading SeatLock, RootLens, TriageIQ and Byte Decoded. POV: YOU’RE ON MY GITHUB glitches in with an RGB split, then stay a while, it’s a vibe, Hemashree · Software Engineer, and the focus areas computer vision, security, backend and DevOps, and embedded and IoT. Two little black cats show up on the street: one waves hey, welcome in! The other chases a ball, trips, says oops…, then i meant to do that. The first replies: smooth. very smooth.

B.Tech CSE at VIT Chennai Location Co-inventor on 2 patents Open source contributor

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 Main projects: Things I've built. SeatLock, RootLens and TriageIQ.

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.

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

05 Patents: Ideas, on file. 2 filings in progress.

Patent 01, Smart Walker: a walker that predicts a fall before it happens. Dual IMUs and load cells, sensor fusion, fall-risk prediction, standalone on Arduino for under $30. Co-inventor, filing in progress.

Smart Walker repository

Patent 02, Hazard-Detection Rover: a rover that explores a disaster zone and flags hazards for rescuers. Q-learning navigation, CNN hazard perception, multi-hazard detection, emergency stop and a live rescue dashboard. Co-inventor, filing in progress.

Hazard-Detection Rover repository

06 Open source: Built in the open.

Open source: merged pull request #126858 to firstcontributions/first-contributions, plus my own MIT-licensed tools: ReadMeow, gitpulse, PortPilot, typewave, typo-arcade, token-meter, Pit Wall and ferrodo.

🤫 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.
