About

CS undergraduate at RIT Bangalore with a focus on backend engineering and distributed systems. I design systems around correctness and throughput — async task queues, distributed peer protocols, caching layers, and DB schemas built for query patterns, not convenience. Published at ICDDS '25 for research on energy-efficient routing in wireless sensor networks. Recognized by IEEE IAMPro for engineering contributions. I work best on problems where the architecture decision actually matters.

Projects

PeerNexus

PeerNexus

A ground-up implementation of the BitTorrent protocol — peer wire protocol, DHT-based tracker-less peer discovery, and concurrent multi-peer download orchestration.

DHT (Kademlia) + PEX for decentralized peer discovery — no central tracker dependency

HALEM-PEGASIS Evaluator

HALEM-PEGASIS Evaluator

A protocol-agnostic simulation engine for benchmarking energy-efficient routing algorithms in Wireless Sensor Networks. Research published at ICDDS '25 (IEEE).

Pluggable routing module architecture enables controlled A/B comparison across identical network conditions
Simulation loop decoupled from UI thread — topology visualization runs without blocking protocol execution
35% reduction in routing computation time vs. baseline PEGASIS; results validated in ICDDS '25 paper

Lumen

Lumen

A backend API service with stateless JWT authentication and middleware-enforced RBAC across all routes — designed to be horizontally scalable from day one.

RBAC enforced at middleware layer — role resolution happens once per request, not per handler
MongoDB schema modeled around access patterns, not normalization — query-first design
Stateless JWT auth enables horizontal scaling without shared session state

Engineering Highlights

  • Distributed Peer Protocol (PeerNexus) — Implemented Kademlia DHT from spec for tracker-less peer discovery. Each node maintains a k-bucket routing table; lookups converge in O(log N) hops. Piece scheduling uses rarest-first selection across concurrent peer connections to maximize swarm utilization.
  • Concurrent Download Orchestration — Managed parallel peer connections via Java thread pool with per-peer state machines tracking choke/unchoke cycles. Eliminated redundant piece fetches via bitfield-based deduplication across active peers.
  • Protocol-Agnostic Simulation Engine (HALEM-PEGASIS) — Designed an extensible core that runs arbitrary WSN routing protocols against identical network topologies. Decoupled simulation state from rendering thread to eliminate UI jitter during high-node-count runs. Published findings in ICDDS '25 (IEEE).
  • Stateless Auth & RBAC (Lumen) — JWT verification and role resolution handled entirely at the middleware layer. No session store dependency — service can scale horizontally without sticky sessions. RBAC policies are defined per-route at registration time, not scattered across handlers.
  • Query-First DB Design — MongoDB schemas designed around read/write access patterns. Embedded vs. referenced document decisions made based on join cost and update frequency — not default ORM conventions.
  • Research Recognition — ICDDS '25 (IEEE) publication on energy-efficient WSN routing. IEEE IAMPro recognized for engineering contributions. Algorithms coursework focused on graph theory, dynamic programming, and complexity analysis applied to real protocol design.
