• ▸Built custom performance testing frameworks for distributed backend systems; implemented load testing using Python and Locust to simulate high-traffic API workloads
• ▸Performed performance testing of Substrate blockchain pallets and extrinsics to measure execution performance and system throughput
• ▸Analyzed latency, throughput, and system bottlenecks across blockchain infrastructure and backend services
• ▸Designed transaction validation frameworks verifying correctness of blockchain state transitions and emitted events across EVM and Substrate environments
• ▸Built and maintained blockchain indexers and event processing pipelines used by backend systems to interpret on-chain activity
• ▸Tested cross-chain bridge infrastructure connecting EVM networks, Substrate chains, and Solana environments
• ▸Developed automated smart contract integration testing frameworks for Solidity contracts and decentralized exchange integrations
• ▸Deployed and tested Uniswap V3 contracts, building Hardhat-based environments to validate SDK behavior, swaps, liquidity operations, and routing logic
• ▸Developed and tested custom smart contracts on EVM and Solana to simulate production workflows and validate backend integrations
• ▸Collaborated closely with backend, blockchain protocol, and DevOps engineers to design testing strategies and validation frameworks ensuring reliability of distributed blockchain infrastructure across development, staging, and production
• ▸Built developer tooling that allowed engineering teams to reproduce complex blockchain transaction flows locally, improving debugging workflows and reducing issue resolution time
• ▸Designed automated validation systems ensuring consistency between on-chain events, indexer outputs, backend database states, and notification pipelines across distributed services
• ▸Contributed to internal engineering documentation and architectural discussions around blockchain infrastructure reliability, AI-assisted diagnostics, and testing strategies for complex multi-service systems

Engineering contributor to Hxro, one of the first binary options trading platforms built on the Solana blockchain, supporting real-time trading workflows and high-frequency market data. Designed and implemented comprehensive testing infrastructure from scratch to ensure reliability of backend APIs, trading systems, and frontend user interfaces in a latency-sensitive financial environment.
