Internal
Administration Tool (Capitual)

Capitual's admin and support teams needed internal tools solid enough to run day-to-day operations across a hybrid banking and cryptocurrency platform, without constant production issues getting in the way.
I built scalable web interfaces with React, Ant Design, Styled Components, GraphQL, and AWS, backed by CI/CD pipelines, and set up an automated testing pipeline covering both E2E and unit tests. I also ran regular pair programming sessions and code reviews to mentor other developers and keep the architecture clean.
Highlights
- Built an automated E2E and unit testing pipeline, reaching 80% coverage on critical flows
- Reduced production bugs by 96% across the internal tools
- Mentored developers through regular pair programming and code review
- Integrated GraphQL API contracts into scalable, AWS-deployed interfaces
Challenges
- Cutting production bugs by 96% on tools the team depended on daily
- Reaching solid test coverage on critical flows without slowing feature delivery
- Keeping architecture clean and consistent while mentoring other developers on the codebase
