• Contributed to the architecture and design of a general-purpose stateful bridge platform enabling cross-chain swaps, staking, and arbitrary message passing, following an in-depth analysis of leading bridging protocols. • Developed multiple Cosmos modules for attestation tallying and reward distribution based on a custom state machine design. Additionally, authored CosmWasm and Solidity smart contracts for core components including gateways, voyage modules, and intent adapters. • Designed and implemented a custom testing framework to validate and enhance off-chain components such as the relayer, orchestrator, and voyager forwarder. Collaborated with the DevOps team to maintain and upgrade multi-stage network environments. • Worked closely with auditors from Informal Systems and Oak Security to ensure a clean, secure, and well-documented codebase. Successfully integrated with prominent blockchain projects including Osmosis, Injective, and Band Protocol.

• Designed and implemented a dual-staking module, enabling users to stake multiple tokens with validators. • Participated in security audits of various cross-chain decentralized applications (dApps) on Ethereum, including modules for concentrated liquidity and on-chain limit orders. • Resolved complex dependency challenges when adapting the Cosmos SDK governance module to a vote-escrowed governance model. • Led the deployment and maintenance of a secure network architecture utilizing Sentry Nodes, leveraging DevOps tools such as Ansible, Terraform, and Prometheus for configuration management, monitoring, and logging.

• Researched Ethereum scaling solutions including payment channels and state channels with underlying theory of Conflict-free replicated data types (CRDTs). • Coordinated development and developed a blockchain-backed international lottery platform infrastructure • Wrote Cosmwasm smart contracts for the money market and performed unit and integration testing of the infrastructure. • Implemented on/off ramp services and earning functionalities by integrating with Wyre, Plaid and Alchemix protocols and deployed the whole infrastructure to AWS.

• Utilized TDD and BDD to improve software quality by 30% and joined in Agile Development and maintained effective communication in the team going through all phases of SDLC. • Restructured the software structure for our company,reducing overhead costs by 24% per month. • Created the initial test strategy by developing test cases, taking them from 0% test coverage to 40%. • Constructed CI/CD pipelines using Jenkins and set up a zero downtime structure using Kubernetes and EKS. • Managed the AWS DevOps infrastructure for the eCommerce sites improving reliability by 50% and helped design the back end and networking architecture for several AWS-hosted eCommerce and donor-matching web apps.
