Proven track record of expecting the unexpected, measuring and using data to enhance the customer experience, and finding the correct entry points for problem solving. ## Work Experience ### Senior Software Engineer @ Tally Jan 2023 – Jan 2025 - Led the integration of Solana into web application, enabling true multi-chain functionality alongside EVM. This consisted of translating Solana programs to JS, building cross-chain token portal support, and assisting in writing APIs to facilitate communication between Solana and EVM. - Orchestrated a comprehensive front-end refactor in collaboration with back-end team, integrating new schemas and endpoints to support a multi-chain application architecture. - Enhanced wallet connectivity by implementing EIP6963 standard, improving overall user experience and giving control back to the users for which wallets they want to use. - Developed custom WAGMI connectors for an outdated version of WAGMI to support EIP6963 connections. - Implemented both sign-in-with-solana and sign-in-with-ethereum specifications on a Go-driven back- end as well as front-end. - Worked closely with Wormhole Foundation to help drive the implementation of MultiGov. - Built a deep linking system for communicating between various Solana wallet mobile applications to enable mobile users to interact with the web application and their wallet to sign transactions, sign messages, connect, and disconnect. ### Consulting Business Owner @ Nox Forest LLC Jan 2022 – Jan 2023 | Washington, United States • Consultation for SushiSwap; developer on Shoyu NFT • Implemented a containerized asset optimization pipeline microservice that saved the project an estimated $25,000 per year. It ingests IPFS assets from a custom Ethereum indexer, optimizes the asset, and stores output in a retrieval bucket. Technologies used: Node, TypeScript, PostgreSQL, Redis, ffmpeg, sharp, TypeORM, GCP, Docker, ImageMagick. • Developed a cutting-edge NextJS NFT marketplace application with Solidity smart contracts, TypeScript, TailwindCSS, HeadlessUI, GraphQL, and WAGMI React hooks. • Created a containerized real-time indexing search engine microservice that achieved an average 100ms search result from millions of indexed documents. It monitored updates and inserts using Debezium Server, Redis Streams, Kubernetes, and Meilisearch. This saved the project an estimated $30,000 per year. • Implemented code as infrastructure using the Pulumi project to set up Kubernetes in GKE. Integration with GitHub actions ensured a fast, reliable, and easily maintainable continuous integration pipeline. • Established monitoring and alerting for infrastructure using Loki, Tempo, Prometheus, Grafana, and Alertmanager, ensuring observability across the distributed system. • Co-implemented a next generation custom Ethereum blockchain indexing service that provides near real-time processing of new blocks as well as indexing historical blocks. This resulted in an average time of 15 seconds before a new block was indexed, saved to the database, and available for customers to view the massaged block data on the marketplace. This saved the project an estimated $150,000 per year compared to using a SaaS solution. Technologies used: StreamingFast's Firehose, Geth, Node, BullMQ, PostgreSQL, TypeORM, Redis, EthersJS, Kubernetes, TypeScript. ### Software Engineer II @ Redfin Jan 2020 – Jan 2022 • Spearheaded the proposal and successful implementation of migrating from a home-brewed, highly customized component documentation solution to Storybook. This strategic move significantly enhanced collaboration and streamlined the design system's development process, empowering other developers to contribute without requiring specialized knowledge of the previous system • Led the initiative to adopt a better visual testing approach for React components by introducing Chromatic. This shift greatly simplified the process of writing visual tests, eliminating the need for specialized knowledge of the previous testing solution. The improved testing infrastructure ensured a higher level of visual consistency and increased development efficiency. • Introduced newer generation React practices to the design systems team, addressing codebase maintenance issues, bug prevalence, and the need for specialized and/or outdated knowledge. By teaching the team about React hooks and transitioning from class components to functional components, I facilitated improved code maintainability, reduced bugs, and enhanced the team's overall development experience. • Proposed and collaborated on migrating to TypeScript, partnering with a developer from another team. We conducted regular migration sessions over the course of a quarter and subsequently presented the benefits of TypeScript to the engineering organization. This effort led to the formation of a dedicated TypeScript working group, which I co-led, and widespread adoption of TypeScript across the organization. • Co-led a React Native working group. Utilizing my prior experience in React Native, I helped migrate major versions of React Native as well as update common React Native components to reflect new design system web components. While leading these efforts, I formulated migration plans and mentored newer engineers to the React Native ecosystem. ### Software Engineer III @ Keap Jan 2019 – Jan 2020 | Chandler, AZ, United States • Developed and extended a voicemail microservice to include the ability to create custom voicemail greetings. This involved implementing Docker, ffmpeg, Google App Engine, and Node to create a scalable and efficient solution. • Increased the frames-per-second from an average of 30 to 60 in areas of the app that were periodically fetching and transforming large datasets. This optimization was achieved by re-implementing costly scroll events, resulting in a more responsive and user-friendly experience for the app's users. • Collaborated with open source library maintainers by actively reporting issues with new releases and opening pull requests. By contributing to the open source community, I helped to improve the functionality and reliability of theses libraries, benefiting the wider developer community. ### Software Engineer II @ Keap Jan 2018 – Jan 2019 | Chandler, Arizona • Enhanced deployment by introducing a mechanism for shipping live updates without the need for the typical approval steps required by Apple. This optimization resulted in faster turnaround times for updates and a more seamless user experience. • Redesigned the mobile app navigation architecture to allow for custom transitions, custom navigation bars, and more declarative routing definitions, accommodating the designer's future vision for the app. This redesign resulted in a more intuitive and user-friendly interface for the app's users as well as increased developer pace and productivity. • Implemented detailed logs at the service and front-end levels to ensure observability and visibility into all points throughout the vertical, improving the reliability and stability of the system. ### Software Engineer II @ Choice Hotels International Jan 2015 – Jan 2018 | Phoenix, AZ • Led the effort to transition our web app from Angular to React by presenting a compelling case to members of the technology assessment committee and developer manager. My ability to communicate complex technical concepts and gain buy-in from key stakeholders helped to ensure the success of this project and demonstrated my potential as a junior engineer. • Conducted ongoing training sessions for web developers on React to get everyone up to speed for replacing our old codebase. I was proactive in ensuring that everyone had the necessary skills to succeed in the transition to React, demonstrating my willingness to take on leadership responsibilities and my commitment to the team's success. • Gave a recorded presentation to web and run teams on identifying performance bottlenecks, which led to the creation of a new team dedicated to addressing performance issues. By sharing my knowledge and expertise, I demonstrated my potential as a junior engineer and contributed to the overall success of the project. • Simplified component architecture by championing for an atomic design pattern rather than a feature-based structure that often resulted in repeated code. My ability to identify opportunities for improvement and advocate for best practices demonstrated my initiative. • Led the accessibility team to create a WCAG 2.0 compliant website, resulting in a potential reach of an additional 19% more users. As a junior engineer, I demonstrated my tenacity and leadership skills by spearheading this initiative and ensuring that all team members were engaged and aligned towards achieving this goal. ### Lead Software Engineer @ Phoenix Blockchain, LLC Jan 2018 – Jan 2018 | Phoenix, Arizona Area Providing custom blockchain and smart contract solutions with a focus on cryptocurrency.
