Smart Contract & Aspiring Protocol Engineer focused on building secure, composable, and production-oriented decentralized systems.

My work spans smart contracts, protocol architecture, on-chain financial primitives, developer tooling, and open-source infrastructure across Ethereum and adjacent ecosystems.

I actively contribute to open-source projects through:

• protocol tooling contributions
• documentation improvements
• frontend integrations
• developer experience fixes
• workflow automation
• ecosystem hackathons and research-driven builds

I'm particularly interested in:

• Ethereum protocol engineering
• EVM internals
• account abstraction
• on-chain identity & attestations
• decentralized finance infrastructure
• zero-knowledge systems
• verifiable financial coordination

• Building production-grade smart contract systems with Solidity + Foundry
• Studying EVM internals and low-level execution
• Learning Rust for protocol/client engineering
• Contributing to open-source Web3 projects
• Exploring Ethereum core infrastructure and protocol research

Built and studied a simplified EVM implementation to better understand:

• bytecode execution
• opcode handling
• stack mechanics
• virtual machine architecture

Tech: Rust

Blockchain-powered agricultural infrastructure project focused on trust, verification, and transparent coordination systems.

Worked on:

• smart contract logic
• frontend integrations
• decentralized workflow design

Contributed to savings/staking integration workflows and UX debugging within a DeFi environment.

Worked on:

• wallet interaction flows
• staking UX
• debugging transaction handling
• frontend integration fixes

An on-chain financial attestation primitive designed to create verifiable proofs of payment, income, and financial activity.

Focus areas:

• smart contract architecture
• attestations
• identity-linked verification
• composable financial proofs

Tech: Solidity Foundry React TypeScript

Building agent-based payment infrastructure integrating:

• Stellar
• CoinFello API
• conversational payment workflows

Tech: React TypeScript Stellar SDK

I actively contribute to open-source projects through:

• documentation improvements
• issue resolution
• developer onboarding
• GitHub Actions/CI setup
• protocol integration work
• frontend and smart contract fixes
• architecture discussions
• community standards/documentation

I enjoy working inside large codebases, understanding system design decisions, and contributing incrementally to improve developer experience and protocol usability.
