About

I'm a B.Tech Computer Science student at NIT Hamirpur, working at the intersection of full-stack engineering, Web3, and systems programming.

Most of my recent work sits in one lane: giving autonomous AI agents money, guardrails, and accountability. Scoped spending cards, runtime firewalls, and on-chain budgets that agents physically cannot exceed. If an agent is going to hold a wallet, something has to sit between it and the money — that's what I build.

Alongside that, I contribute to HPX (the C++ Standard Library for Parallelism and Concurrency) under GSoC 2026, and was selected as an LFX Mentee 2025 under the Linux Foundation for the Magma distributed mobile-core project.

Featured Work

Every project below is public, and every demo link is verified live.

Agent Infrastructure

Vigil — Runtime firewall for AI agents

Intercepts and governs every tool call an agent makes: enforces token budgets, blocks unsafe actions, and streams a full audit trail. Stops a runaway agent before it burns spend or touches what it shouldn't.

GlassPay — Spending cards for agents

Scoped, revocable payment cards for AI agents without ever sharing a private key. Built on ERC-7710 delegations with gasless settlement and end-to-end SigNoz observability. Agents get a card, never a key.

CapMatrix — Budgets agents can't break

Multi-agent chat rooms where each autonomous DeFi agent operates under hard-capped, on-chain enforced spending limits. Capability-based security applied to autonomous finance.

AGORA — Where agents hire agents

A marketplace protocol letting autonomous agents discover, contract, and pay one another for work, with settlement and reputation recorded on X Layer.

Replicant — Evolutionary agent protocol

A decentralized AI agent protocol where agents compete, mutate, and inherit traits across generations, with performance recorded on-chain. Built on 0G Labs infrastructure.

ContextCard — Context-aware finance agent

Wires DataHub metadata and Stripe payments into an MCP server, so agents answer financial questions grounded in real catalog lineage instead of hallucinated schema.

Protocols, Infrastructure & Games

Wraith — Private conditional orders

Your trigger price is encrypted to a TEE and never published on-chain, so it cannot be front-run or hunted by MEV bots. Combines confidential computing with FTSO price feeds and FAssets on Flare.

ContextCI — Autonomous SRE for data

Detects breaking schema changes inside pull requests, traces column-level lineage to find every downstream break, and auto-generates the dbt fixes. Powered by DataHub MCP and GitHub Actions.

TrackRails — Music stem marketplace

Artists lock individual stems (drums, vocals, basslines) into CDR vaults registered as on-chain Story Protocol IP assets. Producers pay to unlock exactly what they need; royalties split automatically.

One Clash Fighters — On-chain fighting game

Retro blockchain fighting game on Movement Network. Players mint NFT fighters, battle AI opponents, stake MOVE tokens in tournaments, and earn on-chain rewards, with a live leaderboard from the Movement REST API.

HPX (STE||AR Group) — GSoC 2026

Contributing to HPX, the C++ Standard Library for Parallelism and Concurrency.

PR Area Contribution
#7036 API Implemented missing standard methods on hpx::compute::vectorassign, at(), reverse iterators — improving std::vector compatibility
#7041 Exception safety Replaced raw memory allocation with std::shared_ptr in options_description_easy_init, preventing leaks on throw
#7046 Memory safety Eliminated unsafe std::strcat in print.cpp in favour of bounds-safe string operations
#7116 CI Refactored build-and-test.yml into a matrix job plus reusable composite action, cutting duplication
#7120 Testing Fixed exact test matching in container-algorithm CI shards, ensuring deterministic execution
#7125 Serialization Replaced std::shared_ptr<double[]> with serialize_buffer<double> in 1d_stencil_5, clarifying buffer ownership

Also built hpx-ci-diagnostics — a CLI that helps HPX developers reproduce flaky tests by stressing them at varying concurrency levels and parsing HPX-specific error signatures.
