About Me

Hey there! I'm a second-year Computer Science student at Southampton University. When I'm not in lectures, you'll find me building blockchain projects, playing basketball and participating in hackathons. I'm also the President of dSoc, where I help organize educational events and workshops to spread blockchain knowledge across campus.

I've got a thing for smart contracts and decentralized systems. There's something exciting about building applications on Ethereum that can't be tampered with or controlled by a single entity. I'm currently interested in EIP-7702 and how it can be leveraged to create dApps that you can delegate funds to for them to use on your behalf - whether that's for better UX or enabling automated financial services.

Whether it's DeFi protocols, tokenization platforms, or building the next generation of Ethereum applications, I love working on projects that combine innovative tech with real-world utility. Drop me a message if you want to chat about blockchain, Ethereum development, or collaborate on something cool!

Currently Working On

Active roles and projects I'm contributing to

0em Labs

Engineering Intern

0em Labs

At 0em Labs, I've been working on building payment systems for our various products. This includes integrating Privy for precise usage-based payments for LLM inference (so you only pay per call, no need to buy tokens upfront), and building smart wallets with social login that make Web3 way more accessible to regular users by abstracting away all the complex Web3 stuff.

I've also been working on an SDK that gives developers easy access to custodial wallets with delegation systems. It includes custom on-chain rate limiting that lets agents handle transactions for users - basically enabling automated services to do financial stuff on your behalf while keeping everything secure and tied to your wallet. I've also been adding X402 monetization for MCP providers, making it easier for them to get paid for their services. It's been pretty interesting figuring out how to balance convenience with security.

Co-Founder

Lyneth

With Lyneth, I've been building an advanced smart contract security platform with my close friend Ojas - it's based on a previous project we worked on called CodeGene but with much more sophisticated AI agents and a full web application instead of just a VS Code extension. The agent has memory and can reference project documentation, so it understands the purpose of each contract and remembers previous scans to analyze what's changed between versions.

We've built a comprehensive webapp with project management, scan history tracking, and direct GitHub integration with CI/CD pipelines. The agent can access your repo, understand your project's context through documentation, and provide much more intelligent analysis than basic vulnerability scanning. It's basically like having a security expert that actually remembers your codebase and gets smarter over time.
