Rudra Mahapatro | Systems & Security Engineer

Founder @ Vector 384 | CS @ NIT Rourkela

I build "hard" software—systems that must perform under adversarial pressure, high-frequency loads, or strict compliance mandates. My work bridges the gap between low-level systems programming (Rust/C) and scalable product engineering.


⚡ Engineering Philosophy

I don't just write code; I engineer survivability.

  • Performance: If a scanner takes 10 seconds, I want to know why it can't run in 100ms.
  • Safety: I prefer memory-safe languages (Rust) for infrastructure, but write C to understand the OS kernel.
  • Reality: I build products, not just demos. My projects include billing systems, abuse rate-limiting, and fault-tolerant pipelines.

🛠️ The Arsenal (Featured Work)

High-Performance Secret Scanner (Rust)

The Problem: CI/CD scanners are too slow for large monorepos and too noisy for developers.

I engineered a zero-copy secret scanner using memory mapping (memmap2) and parallel processing (Rayon) to achieve scan speeds order-of-magnitude faster than standard tools.

  • Architecture: Hybrid pattern-matching engine with 66 vendor-specific validation rules.
  • Enterprise Ready: Emits SARIF 2.1.0 logs for native GitHub Advanced Security integration.
  • Impact: Near-zero false positives; runs fast enough to be a pre-commit hook.

Real-Time Surgical Telemetry Engine (Python/Redis)

The Problem: Medical anomaly detection needs to be fast (real-time) and idempotent (cannot lose or duplicate data).

A fault-tolerant physiological anomaly engine processing ~3,000 events/second with sub-5ms latency.

  • Resilience: Built on Redis Streams for event bus orchestration, ensuring data integrity even if worker containers crash.
  • Intelligence: Uses unsupervised machine learning (Isolation Forest) to flag clinical deterioration in real-time (HR/SpO2 thresholds).
  • Validation: Tested on real surgical datasets (VitalDB), not synthetic noise.

Windows-Native Defensive Proxy (C / Win32)

The Problem: Understanding how firewalls work by building one on the metal.

A multi-threaded HTTP proxy written in ANSI C using raw Win32 sockets. It acts as a miniature perimeter firewall.

  • Defense: Implements real-time packet inspection to block SQL Injection (' OR 1=1) and Path Traversal (../) attacks.
  • Concurrency: Manages raw threads to handle multiple clients simultaneously, supporting both IPv4 and IPv6.
  • Active Measures: Tracks per-IP behavior and automatically bans clients exceeding 50 requests/15s.

Identity Security Platform (Python/Streamlit)

The Problem: Security tools are often just scripts. I wanted a product.

A monetized security dashboard that acts as a "Personal SOC" for monitoring identity leaks.

  • The Tech: Integrates HaveIBeenPwned and GitHub APIs to scan for leaked credentials, assigning a risk score (0-100) via ML anomaly detection.
  • The Product: Full SaaS architecture including Stripe for billing, rate-limiting quotas to prevent abuse, and compliance-style PDF reporting.
