Staff Software Engineer Jan 2022

Aspire is a robust marketing platform that helps ecommerce brands build influential creator communities and manage marketing campaigns. As a Staff Engineer, I joined a ~35 engineer team with a mission to execute the company's technical vision, mentor engineers, and lead cross-team projects.

  • I developed and integrated the first version of our creator platform with Instagram Creator Marketplace. This enabled our users to use Instagram Direct Messaging for campaign communications, streamlining the process. The project was developed in collaboration with Meta, providing Aspire with strategic access to exclusive features and data on Instagram creators.
  • I led the implementation of back-end services testing, setting up CI/CD support core libraries, scaffolding, and configuration. I performed demos, provided code examples, and one-on-one mentoring. The initiative resulted in a decrease in bug reports and severity of issues, minimized product downtime, and increased development velocity.
  • Python, Typescript, GCP, PostgreSQL, Kubernetes, Redis

Dumpling is a platform that provides tools to help individuals start, run, and grow their local shopping and delivery businesses. As an early stage team member I took charge of improving the shopping product database.

  • Developed internal tools for managing the store and product catalog, as well as related features. These tools were instrumental in reducing the turnaround time needed to resolve data quality issues, resulting in a more efficient and streamlined process.

Homeroom is an all-in-one platform to set-up, manage and shop for enrichment activities after school. Joined as an engineer and tech lead to scale the current platform and build new features.

  • By redesigning the locking strategy and fine-tuning the production environment, I was able to optimize backend performance by 300% during peak load. This resulted in increased sales and a 50% reduction in infrastructure costs.
  • I developed a command-line tool that enabled the creation and deployment of isolated testing environments. By testing each feature individually rather than all at once, this streamlined our process, minimized conflicts, and increased our development velocity.
  • As a mentor, I provided guidance to team members, conducted thorough code reviews, and offered support with architecture and system design. Fostered a culture of collaboration and continuous improvement within the team.
