Work Experience

Software Engineer @ Superagent

March 2025 - Present in San Mateo, CA

Day-one founding full-stack engineer at Superagent, formerly DeepSky, acquired by Airtable.

  • Built backend systems and data models to store and organize hierarchical data generated by multiple AI agents running concurrently, improving reliability and traceability of automated workflows.
  • Implemented real-time streaming of AI tool execution and generated content to a React frontend using HTTP keep-alive and server-side streaming (Python, Redis), improving transparency and user trust.
  • Partnered closely with product and design to deliver intuitive, high-quality frontend experiences, rapidly iterating based on customer feedback.
  • Integrated Google OIDC into a self-hosted authentication stack using Ory Kratos, enabling SSO and improving security.
  • Built analytics and observability tooling across services to track hundreds of thousands of daily events, improving debugging, performance visibility, and product decision-making.

Software Engineer @ Expo

October 2023 - March 2025
  • Independently implemented audit logs for Expo’s primary API, enhancing security and user accountability by tracking actions within organization and personal accounts.
  • Developed a dynamic re-authentication approach for securing sensitive tasks, allowing secure, on-demand user re-authentication without manual front-end configuration for each action.
  • Improved the authentication flow for organizations using single sign-on by creating new API routes and matching expected behavior between five different single sign-on providers conforming to the OIDC specification.
  • Automated the process of retrieving billing history for financial tracking purposes, utilizing the Stripe API with Google Cloud functions to automatically ingest data into BigQuery tables, enabling regular data analysis and metric creation.

Software Engineer @ Microsoft

August 2022 - October 2023
  • Independently began the development of new software tooling for security researchers by creating React web apps that interact with Azure Serverless hosted Python and TypeScript APIs.
  • Developed high-performance and scalable APIs using serverless functions while supporting developers by requiring OpenAPI documentation for all services.
  • Participated in product demos and feedback sessions that led to the establishment of new partnerships with other teams to share and ingest new through teams respective APIs.
  • Identified areas lacking tooling when working on assigned features to independently develop two internal tools for visualizing and creating advanced data models used by security researchers.
  • Leveraged a combination of SQL and TinkerPop Graph databases to optimally store and query complex data sets while designing automated pipelines for ingesting and validating data.
