hi, i'm kartikey
I build tools that solve real problems. Production software deployed in clinical environments where accuracy and uptime directly impact patient care.
// Projects
Zypher
Modular web platform to embed and verify encrypted data inside AI-generated images using cryptographic hashing and steganography. Features RESTful API architecture with separate services for media generation, data embedding, extraction, and verification.
GhostAuth
ZKP authentication system where the client generates Groth16 proofs from SHA-256 hashed credentials and the server verifies proof structure without ever receiving plaintext passwords. Split-screen UI visualizing real-time proof generation vs. server-side verification.
DICOMizer
Desktop application to convert endoscopy and arthroscopy video files into DICOM format for clinical PACS integration. Built to solve an operational gap where no commercial solution existed. Currently deployed in production at UGA Veterinary Teaching Hospital.
VetFlow
Local automation harness that streamlines veterinary radiology case entry by extracting patient data from EMR and populating teleradiology forms, accelerating workflow by 20% across 40+ daily cases. Keeps all patient data on-device for HIPAA compliance.
ImagetoDicom
Multi-format (JPEG, BMP, PNG, PDF) to DICOM converter with no commercial equivalent, reducing a 4-hour manual process to 15 minutes.
PixBurn
DICOM annotation tool that burns text, arrows, and shapes directly into pixel data for permanent markup, eliminating dependency on viewer-specific overlays.
// About
Background
I'm a software engineer who builds tools that solve real problems. Not class projects, but production software deployed in a clinical environment where accuracy and uptime directly impact patient care.
As the sole systems coordinator at UGA's Veterinary Teaching Hospital, I identified workflow gaps with no commercial solutions and engineered my own: a multi-format DICOM converter that cut a 4-hour process to 15 minutes, a video processing pipeline saving ~500 GB annually, and an automation harness using local LLMs for HIPAA-compliant radiology workflow automation. I also led a SQL Server migration to Always On Availability Groups, eliminating recurring production outages across a multi-node architecture.
Outside work, I build with genuine curiosity. An audio steganography engine that hides voice messages inside image pixels, a zero-knowledge proof authentication demo using Groth16 and snarkjs. What drives me is simple: I love engineering novel solutions to problems nobody else has solved yet.
