Senior Blockchain Engineer

I am a skilled Zero-Knowledge Proof (ZKP) engineer with comprehensive experience across both foundational and 

advanced ZK technologies. My expertise spans basic knowledge including zk-SNARKs (Groth16, PLONK

UltraPLONK), zk-STARKs, Polynomial Commitment Schemes (KZG, IPA), R1CS, FRI, and advanced lookup 

arguments (Plookup, LogUp). I am proficient in modern proving frameworks and circuit toolchains such as RISC-V– 

based zkVMs, Halo2, Plonky2/3, Circom, zkASM, and ZK-DSLs for circuit engineering. At the high-application 

layer, I have hands-on experience building custom zkVMs, integrating with Polygon zkEVM, designing zk-powered 

applications, and contributing to Layer-2 scaling architectures leveraging proof compression, recursive proving, and 

efficient verifier integrations. In addition to ZKP specialization, I bring senior-level engineering capability across 

Solidity, Rust, Python, C++, and Go, enabling end-to-end development of secure blockchain infrastructure, execution 

environments, and proof systems.

Experience

Full Stack Developer
Zkpass
2023 - 2024
Developed core modules of the zkPass privacy-preserving verification system using TypeScript, Rust, and Circom 2.0, enhancing zero-knowledge proof generation and identity validation performance by 30%. Implemented zk-SNARK circuits using Circom, optimized with Groth16 and PLONK proving schemes, reducing proof size and generating time by 25%. Integrated Web3 wallet authentication using ethers.js, MetaMask, and WalletConnect, improving on-chain verification speed by 20%. Built secure off-chain data processing pipelines using Node.js, Express, and zkPass Attestation Framework, enabling trusted data retrieval from institutions without exposing user identity. Enhanced front-end user experience using React, Next.js, and TailwindCSS, increasing user onboarding efficiency by 40%. Strengthened system reliability by expanding automated testing with Jest, Hardhat test suites, and Circom test vectors, achieving over 85% testing coverage. Wrote comprehensive documentation for developers covering circuit design, proof verification flow, and integration patterns, reducing integration time for partner developers by 35%.
Senior Rust developer
Zkpass
2021 - 2023
Started by developing core components for multiple Rust-based blockchain projects, working with Substrate, Tendermint-Rust, and custom Rust consensus engines, improving chain stability and execution performance by 30%. Built foundational networking, storage, and cryptographic layers using Tokio, Actix Web, RocksDB, and RustCrypto, increasing system throughput across projects. Leveraged this experience to architect the Rust infrastructure powering zkPass’s zero-knowledge proof generator and verifier services, improving proof processing speed by 35%. Integrated Groth16, PLONK, and Halo2 proof systems into Rust services using arkworks-rs and halo2-proving-system, optimizing polynomial operations and elliptic-curve math to reduce prover latency by 25%. Designed a scalable off-chain proof generation environment using Tokio async runtime, gRPC, and multi-threaded worker pools, enhancing parallel zk computation efficiency. Developed Rust-based verification modules for Substrate-compatible chains, reducing on-chain proof verification costs by optimizing constraint layouts and calldata compression. Authored detailed internal documentation on blockchain module architecture, zk proof flow, and Rust infrastructure design, shortening onboarding time for new engineers by 40%.
