Code on GitHub

Six things I built in 2026

Then the rest of the 78 I can show you, from 131 repositories, searchable.

Rulecam

Meta Global AI Developer Hackathon, Nov 2026

Cameras you instruct in plain words, in your own language, with every alert checked by a second model.

  • Proves each rule before it goes live, then logs evidence your browser can verify against a Merkle root
  • Planner, guardrails and alert checks run on Meta's Muse models and SAM 3.1
A verified Rulecam alert: the rule asks for 4 metres from a moving forklift, the floor measured 2.90 m, and the models that planned, measured and checked it are listed with their timings
A recorded Rulecam alert: 2.90 m measured against a 4 m rule, then checked by a second model.

Steward

Open source, MIT, Nov 2026

An open-source AI steward with a computer of its own. It does the work, asks before it acts, and keeps a record.

  • Sending, paying, signing and deleting stop on a card until you answer
  • Every action is sealed into a hash-chained record the app re-checks
Steward's Record page in dark mode: record intact, 22 entries verified, each action listed with its outcome
Steward's Record on its demo inbox: 22 entries, each sealing the one before it.

Mirage

Final-year project, University of Hertfordshire, 2026 to 2027

A gateway that detects distillation theft of AI models sold through an API, and proves ownership of stolen copies.

  • Responds in grades (watch, slow, silent degrade, clearance) instead of banning
  • Logs fingerprints, never email text, in a hash chain with Merkle batch roots

IntentGuard

Hackathon build, Aug 2026

A cross-chain treasury agent where the AI makes the decision and the chain enforces the limits.

  • Goals become ERC-7683 intents; each solver route is risk-scored, red-teamed and fork-simulated
  • An on-chain policy vault reverts any order outside the user's mandate, even one signed by a compromised agent

OPUS

Built for surgeons and researchers, Aug 2026

Clinical photography and research records for surgeons, isolated per user with row-level security.

  • Patient registry, media by surgical stage with post-operative day, study cohorts and an immutable audit trail
  • 86 of 86 backend integration tests passing

AlertForge

Security, Jul 2026

An autonomous SOC war room: open-source LLMs fold alert storms into incidents and triage them with specialist agents.

  • 96.7% alert noise reduction
  • Irreversible containment stays behind deterministic guardrails and human approval

Research with numbers I can rerun

Multilingual phishing defence, and voice AI that people who speak Indic languages can afford.

0.9954F1

UniPhish on 7,199 held-out real-world URLs, measured in my 2026 reproduction of the paper.

UniPhish: Unicode-Native 1D-CNN for Multilingual Phishing URL Detection in Messaging Applications

Jeevith Gangadhar, Raunak Khandelwal, K. Shashank Reddy, Sudhina Kumar G. K., Hareesha K. S.. IEEE (under review), 2025

A byte-level 1D-CNN that reads every URL as UTF-8 bytes, so one model with a 256-token vocabulary covers Latin, Arabic, CJK, Devanagari, Hangul and mixed scripts. In 2026 I reproduced the paper end to end and published where it held and where it did not.

Two of the paper's claims did not reproduce: the parameter count, and that ASCII detectors are blind to non-Latin scripts. The rerun says so openly; the byte-level design earns its place on homoglyph robustness.

Technical details
  • Reported in the paper: 98.7% macro-average accuracy across 6 script families; 98.9% macro-F1 with 0.43 ms prediction latency on CPU; 668× faster than Multilingual BERT at equal accuracy; 96.1% accuracy against Unicode homoglyph attacks; 4.2 MB compressed model for sub-1 ms mobile inference
  • Dataset: MultiPhishDB, a 487,523-URL multilingual benchmark (κ = 0.91)
  • Threat intel: Real-time hunting over Certificate Transparency logs, producing STIX 2.1 and TAXII 2.1 indicators mapped to MITRE ATT&CK
  • Technologies: 1D-CNN, UTF-8 encoding, TensorFlow, TensorFlow Lite, Adversarial training, FastAPI

Affordable Multilingual Voice Agents: A Self-Hosted Architecture for Indic Languages

Jeevith Gangadhar, Dr. Nagaraj Naik. Manipal Institute of Technology, 2025

A self-hosted voice agent for Hindi, Tamil, Telugu, Kannada, Tulu and English with automatic language identification, built to cost a fraction of commercial voice APIs.

It also flags emotional distress, for the safety-critical calls a voice agent should never miss.

From Manipal to Hatfield

In 2026 I moved to the University of Hertfordshire for the final year of my Computer Science degree.

Jeevith Gangadhar

I build full-stack and backend systems end to end, then measure them: a platform grown to around 10,000 users, a 742 ms real-time voice pipeline, a phishing model that runs in 0.76 ms on a laptop CPU.

My first product, a university companion app, was acquired by Colcord, where I went on to lead the V1 platform. Since then I have built voice agents at VoiceDots, worked in Ericsson's Infrastructure and Network Security team, and built clinical ML with doctors at Kasturba Hospital.

My research is on UniPhish, multilingual phishing detection, and affordable multilingual voice agents for Indic languages. Outside coursework I play CTFs and build in the open.
