Rishabh Agrawal — Senior Software Engineer

👋 Hi there! I'm a Senior Software Engineer specializing in backend systems and blockchain infrastructure with 4+ years of experience building production-grade distributed systems.

🚀 Professional Summary

Senior software engineer with 4+ years building production backend and blockchain infrastructure in Go, Rust and TypeScript — owning architecture, implementation, and production reliability end-to-end. Designed systems sustaining 11,000 TPS (1B+ transactions/day), shipped protocol-level integrations across OP-Stack, Arbitrum Nitro, Polygon CDK, ZK Sync Era, and Sovereign SDK adopted by 7+ production L2s, and contributed upstream changes merged directly into OffchainLabs/nitro and Sovereign-Labs/sovereign-sdk.

Operates comfortably at every layer — distributed Go backends, Rust sequencer internals, ZK proof pipelines, Solidity settlement contracts, and cross-chain cryptographic signing systems.

💼 Professional Experience

Senior Software Engineer — Backend & Blockchain Infrastructure @ Avail Project

Aug 2023 — Mar 2026

• High-Throughput EVM Pipeline: Built end-to-end system sustaining 11K TPS (1B+ transactions/day) with distributed fleet management, concurrent transaction generation, and real-time transaction indexing
• Rollup Integrations: Designed and implemented DA adapters across leading rollup stacks (OP-Stack, Arbitrum Nitro, Polygon CDK, ZK Sync Era, Sovereign SDK)
• Upstream Protocol Contributions: Core DA interface changes merged upstream into OffchainLabs/nitro and Sovereign-Labs/sovereign-sdk
• Production Rollup Adoption: Built DA integration and Solidity verifier contracts; adopted by Space and Time (SxT), Sophon, and Lens
• Browser-Native Verification: Ported DA verification logic to WASM module for browser-native chain verification

Backend Engineer @ Polygon Labs

Dec 2022 — Aug 2023

• Polygon PoS Open APIs: Implemented validation logic for public-facing APIs with full test coverage and load testing
• Watchgod — Real-Time Transaction Pipeline: Designed event-driven transaction status service reducing confirmation latency

🌐 Open Source Contributions

I've made significant contributions to the blockchain ecosystem with integrations adopted by multiple production L2s:

• Arbitrum Nitro — Core interface changes merged into OffchainLabs/nitro
• Sovereign SDK — DA adapter merged into Sovereign-Labs/sovereign-sdk
• OP-Stack — DA adapter with full integration documentation
• Polygon CDK — DA module for validium chains
• ZK Sync Era — Sequencer modifications with diamond proxy contracts
