Random Number Generator:

• Developed distributed random beacon system from scratch using Go and PostgreSQL, supporting up to 33 concurrent nodes.
• Implemented cryptographic commit-reveal protocol utilizing Merkle trees, ECDSA signatures, and Ethereum smart contract integration.
• Designed fault-tolerant LibP2P peer-to-peer networking with automatic failover and real-time event monitoring.
• Created time-based monitoring system featuring sequential revelation protocol to prevent manipulation attacks.
• Built robust error handling with exponential backoff and fallback RPC clients, managing dynamic gas pricing.
• Orchestrated multi-phase protocol: registration, commitment, revelation, and random number generation with timing controls.
• Established automatic node ejection system to remove unresponsive or malicious validators for protocol reliability.
• Optimized database queries to enhance data retrieval and application efficiency.
• Created technical documentation for software features and system architecture.

Sybil Resistance:

• Created and developed the architecture for Sybil resistance smart contracts. The contract assigns a score to each address. This score represents how trustworthy a contract is.
• Implemented cumulative scoring system combining staking contract deposit amount with Sybil resistance scores.
• Built a sparse Merkle tree verification system for secure user score validation.
• Designed upgradeable proxy contracts with role-based access control using OpenZeppelin security standards.
• Developed a snapshot governance service for decentralized voting, with Sybil-resistant user verification and weighted scoring.

• Developed and managed Bridging Ecosystem for Jumpnet, blockchain communication hub with libP2P and Go Ethereum, and an EVM compiler in Rust for private blockchains.
• Contributed to the OP stack sequencer for Ethereum Rollups and developed a Trustless bridge for OP stack rollup.
• Played a key role in building blockchain infrastructure, including multisig wallets for Bitcoin, Ethereum, and Ripple.
• Integrated major EIPs and conducted research on DeFi protocols.
• Implemented liquidity for staked tokens using a LIDO fork and worked with protocols like Aave, Balancer, Compound, and Curve.
• Created an ERC4626 and ERC5095 compliant futures vault and established governance using principle tokens.
• Developed upgradable smart contracts with a focus on security, employing solutions like Transparent Proxy, UUPS proxy, and Beacon proxy.
