Supersol is the world’s first Solana-native Layer 2, achieving tens‑of‑thousands TPS and sub‑millisecond transaction latency using Rust-based Evanescent Rollups. - Architected the full SuperSol Layer 2 (L2) infrastructure for Solana, enabling up to 10x transaction throughput improvement via Evanescent Rollups with off-chain execution and Sparse Merkle Tree-based state commitments. - Led the implementation of the Shared Liquidity Layer, reducing liquidity fragmentation by over 60%, enabling seamless asset movement across SuperSol L2s and Solana L1 through IBC-inspired unified liquidity pools. - Spearheaded the architecture of fraud-proof and zk-proof transition mechanisms, integrating Celestia for Data Availability and building an interactive proof system for conflict resolution at scale. - Integrated Celestia as the external Data Availability Layer, enabling scalable off-chain storage and reducing on-chain data load by over 70%, critical for maintaining throughput during peak usage. - Designed and deployed a centralized sequencer model for initial network bootstrapping, enabling low-latency rollup block creation and predictable throughput under early adoption conditions.

Contributed to 15+ blockchain startups and client projects from 2017 to 2023, delivering smart contracts, dApps, and infrastructure across Ethereum, Solana, and Substrate. - Architected and led the development of 10+ blockchain systems across Ethereum, Solana, and Substrate, including DeFi platforms, cross-chain bridges, and NFT marketplaces, serving over 500K+ users globally. - Designed and deployed Layer 2 scaling solutions (e.g., optimistic rollups and custom sequencers), achieving up to 65% reduction in gas fees while maintaining high throughput and decentralization. - Developed and audited 80+ smart contracts in Solidity, Rust, and Move with 100% successful audit pass rate, leveraging frameworks like Hardhat, Foundry, Anchor, and MythX. - Built high-performance indexers and on-chain data pipelines using tools like The Graph, Helius, and custom WebSocket-based indexers, scaling to 10M+ transactions processed in real time. - Managed distributed teams of up to 12 developers, defining architecture, code standards, and CI/CD pipelines, resulting in 40% faster feature delivery and improved system resilience.
