πŸ‘¨πŸ»β€πŸ’» About Me

Hi, I'm Sandip Godhani πŸ‘‹

Computer Engineering student passionate about building scalable, real-world applications. I enjoy turning complex ideas into practical solutions through clean code and thoughtful system design. Currently focused on full-stack development, real-time systems, blockchain and Web3. Actively building projects like ChatApp (E2EE messaging) and SafeX (crypto wallet), while contributing to open source and exploring new technologies.

πŸš€ Featured Case Studies & Architectures

πŸ›‘οΈ SafeX β€” Crypto Wallet

Zero-Trust Self-Custodial Web3 Vault

Repository Case Study

An enterprise-grade, 100% non-custodial multi-chain crypto wallet built from fundamental cryptographic primitives with zero central database trust.

Key Architectural Highlights:

  • Argon2id Memory-Hard KDF & AES-256-GCM: Client-side vault demanding 64 MB dedicated RAM per hash, thwarting GPU brute-forcing.
  • Active RAM Zeroization: Ephemeral memory handles wiped via buffer.fill(0) on tab timeout or lock.
  • Multi-Chain Derivation: BIP-39 entropy to EVM (BIP-44) and Bitcoin Native SegWit (BIP-84 Bech32).
  • Offline EIP-1559 Signing: Raw bytecode serialized and signed on-device before JSON-RPC broadcast.
  • Uniswap V2 AMM Swaps: Constant-product routing (x Β· y = k) with slippage bounds.
  • Resilient Multi-Provider RPC: Zero-downtime automated failover across public RPC nodes.

πŸ’¬ ChatApp

Real-Time E2EE & WebRTC Communications Platform

Live Demo Repository Case Study

A production-ready real-time communication platform engineered for end-to-end privacy, low-latency audio/video calling, and persistent sessions.

Key Architectural Highlights:

  • End-to-End Encryption (E2EE): Asymmetric ECDH (P-256) key exchange combined with AES-GCM-256 payload scrambling.
  • WebRTC Voice & Video: P2P signaling via Socket.IO, picture-in-picture stream, live mute/unmute, and screen-sharing.
  • Sub-50ms Socket.IO Sync: Instant message dispatch, live typing indicators, online presence, and reactions.
  • 30-Day Session Persistence: Better Auth configured with Partitioned cookies and instant localStorage cold start.
  • Offline Resilience: IndexedDB JWK serialization and Service Worker message queuing.

πŸ““ MyJournalApp

Offline-First Progressive Web App

Live Demo Repository Case Study

A personal journaling PWA designed to work effortlessly without an internet connection, featuring an autonomous synchronization pipeline.

Key Architectural Highlights:

  • Queue Compaction Engine: Intercepts offline operations in IndexedDB, intelligently collapsing duplicate writes before server dispatch.
  • Temporary ID Resolution: Seamlessly reconciles client-side temporary keys into server MongoDB ObjectIDs with zero UI flicker.
  • Anti-Lockout Cache Handling: Custom Network-First SWR pipeline for documents preventing blank screens on new bundle releases.
  • Dynamic Chunk Recovery: React ErrorBoundary catching chunk load failures on offline navigation.
  • Push Notifications & Reminders: Native background Web Push (VAPID) and automated reminder notifications via Node-Cron.

πŸ”— Smart Link Intelligence

Behavior-Aware URL Routing & Analytics Engine

Live Demo Case Study

An intelligent traffic classification and routing engine that dynamically adapts destination endpoints based on visitor behavior and device attributes.

Key Architectural Highlights:

  • Dynamic Traffic Routing: Heuristic visitor classification driving personalized redirect flows.
  • Telemetry & Analytics: Deep breakdown of referrers, device footprints, geographies, and timestamps.
  • Resilience & Security: IP-based rate limiting, bot protection, and automated traffic shaping.
  • Interactive Dashboards: Comprehensive analytics tracking clicks, devices, browsers, and conversions.
