About Me

Hey there! I'm Prasant, a Computer Science student who likes to work in large scale infra and systems engineering. Currently a Meta PE Fellow and former RA working with ML models, I'm also really interested in research in general.

I've recently built Lavender, an open source distributed Linux EDR system with a Rust eBPF kernel module and Go-based detection workers.

I LOVE doing hackathons and working with large scale infra, so hit me up on linkedin if you wanna team up for hackathons or any project really!!

AI/ML Research Assistant

Cyber Innovation Lab | USM, Hattiesburg, Mississippi

Sept. 2025 - Feb. 2026

  • Built and trained a ModernBERT-based co-attention neural network in PyTorch for social engineering email detection, achieving 100% accuracy on a held-out test set of 158 email pairs.
  • Engineered an email pair processing pipeline from a preprocessed dataset derived from 500,000+ corporate emails, generating 171 structured emails across 4 attacker profiles.
  • Trained a 151M+ parameter transformer with AdamW over 20 epochs, reducing validation loss from 0.57 to 0.0009 while maintaining perfect precision, recall, F1, and AUROC
  • Integrated the model with an upstream GNN-based anomaly detector, achieving 92% end-to-end system accuracy for social engineering detection

Projects

Lavender — Open Source EDR logo

Lavender — Open Source EDR

Distributed Linux endpoint detection and response system with real-time threat visibility.

  • Built a distributed Linux threat detection system in Go with real-time dashboard, detection workers, and structured event logging for hardware and system diagnostics.
  • Wrote a Rust eBPF kernel module intercepting Linux syscalls and kernel tracepoints; structured event logs for anomaly detection and hardware diagnostics.
  • Implemented NATS-based event streaming as a single source of truth, ensuring ordered, lossless data flow across detection workers and dashboard.

No-Brainrot - Productivity Focused Browser Extension logo

No-Brainrot - Productivity Focused Browser Extension

Browser Extension that helps you stay focused by blocking short-form content and tracking your web time.

  • Short-form content blocking Chrome browser extension across multiple platforms with 289 installs & 20 daily users.
  • Built a browser extension that blocks certain sites and tracks time, using TS, Webpack, IndexedDB, and Chrome Extension APIs.
  • Eliminated a race condition in IndexedDB writes by serializing add/update operations with a queue and transaction guards, ensuring consistent time-tracking data.
  • Structured background, content, popup, and dashboard modules with shared types and utilities, improving code reuse and maintainability across extension surfaces.
  • Added time analytics for the dashboard to surface usage insights while keeping computation local for privacy.
