I lead the architecture and implementation of Universal Validators at Push, a distributed validator network that monitors external chain activity, performs threshold voting and gas-price oracle updates, and executes cross-chain transactions using TSS-based signing over a libp2p layer. I also designed and built the Core SDK that enables universal, fee-abstracted interactions with Push Chain from both EVM chains and Solana through clean VM-agnostic abstractions. Alongside this, I drove research on Shared State for cross-chain read/write functionality across EVM and Solana, and conducted R&D for Push Wallet, exploring shard-based wallet design using Shamir’s Secret Sharing and passkey-based recovery. I scaled Push Chat groups from 1.5k→25k (public) and 50→5k (private) by introducing shared-secret encryption with dynamic session keys, and I designed and implemented the Subset Notification system that reduced delivery time for 1M+ users from over 3 minutes to just 3.8 seconds. My work spans Golang, NestJS, Node.js, RabbitMQ, TypeScript, SQL, Redis, Docker, IPFS, crypto-js, and openPGP.

I was selected as one of 50 participants from over 5,000 applicants to learn Bitcoin fundamentals and contribute to Bitcoin open-source projects. During the program, I built a modular implementation of the Bitcoin Wallet UI Kit, translating the official design guide into isolated, reusable components that could be used across Android, iOS, and Web wallets. This work involved designing and documenting components using React Native Web, MobX, Storybook, SVGR, and Figma to ensure consistency, portability, and developer-friendly integration.

I contributed to a large job-marketplace platform where I significantly improved site performance, reducing page load times from 7.8s to 2.3s. I designed scalable MongoDB schemas and built robust CRUD APIs to manage company profiles and job listings, ensuring smoother data flow and better reliability across the system. My work spanned both frontend and backend, using React.js, Node.js, MongoDB, Mongoose, Material-UI, and Formik to deliver a fast, intuitive experience for end users.
