💻 Tech Stack

🔷 Core Backend & Frameworks

Java Spring Boot Spring Security Hibernate Python C++

🗄️ Distributed Systems & Databases

Apache Kafka Redis PostgreSQL MySQL Microservices

🔐 Security & DevOps

Docker Kubernetes Git Linux JWT OAuth2

🚀 Featured Projects

🛡️ SentinelGate

Edge Security API Gateway

A stateless, high-throughput security gateway that monitors backend services in real-time, detects abnormal traffic, and enforces automated defensive measures.

Key Design Decisions:

  • Problem → Low-latency request interception without blocking the main I/O thread
  • Solution → Asynchronous Kafka pipeline with Redis caching for threat analysis and IP blacklisting

Highlights:

  • 🔍 Device fingerprinting & real-time anomaly detection
  • 🚫 Automated IP blocking and rate limiting
  • 🔐 RSA Cryptography for request signing

Spring Kafka Redis Docker

🥉 Centralized KYC System

Consent-Driven Distributed Identity Platform Alpha 🚧

A microservices-based KYC orchestration system that eliminates redundant verification across institutions while enforcing secure, consent-based data access.

Key Design Decisions:

  • Single Source of Truth → One verified identity reusable across organizations
  • Consent → Explicit user authorization required before any data access
  • Event-Driven → Asynchronous communication using Kafka
  • Security → JWT authentication, RBAC, and encrypted data storage
  • Lifecycle → Automated renewal, revocation, and update workflows

Highlights:

  • 🔐 Consent-based identity sharing with strict access control
  • ⚡ Event-driven microservices using Apache Kafka
  • 🏛️ Multi-institution KYC orchestration
  • 📊 Strong data governance and trust boundary enforcement

Java Spring Boot Kafka MySQL Redis Docker

🎓 Real-time Proctoring Engine

Event-Driven Exam Platform

Low-latency WebSocket-based examination platform with real-time anomaly detection for large-scale concurrent sessions.

Key Design Decisions:

  • Scale → Efficient session mapping for thousands of concurrent WebSocket connections
  • Detection → Tab switching, focus-loss, and behavioral event monitoring

Highlights:

  • ⚡ Persistent bidirectional WebSocket connections
  • 👁️ Multi-event anomaly detection pipeline
  • 📊 Real-time session state management

Java Spring Boot React

🧬 Heuristic PDF Malware Analyzer

Automated Threat Detection Pipeline

Static analysis + ML pipeline to classify polymorphic malicious payloads hidden within PDF structures.

Key Design Decisions:

  • Innovation → Custom structural parsers to identify high-entropy object streams in malformed PDFs
  • Accuracy → XGBoost ensemble model for classifying zero-day polymorphic variants

Highlights:

  • 🧠 XGBoost + TensorFlow classification pipeline
  • 🔬 Custom PDF structure parser for malformed documents
  • 📈 High-entropy stream detection

Python TensorFlow XGBoost
