Internship Full-stack Engineer resume example

• Under supervision, carried an account-setting change through the React form, API validation and database migration; exercised stale submissions and permission failures in end-to-end tests.
• The team shipped a customer onboarding workflow across React, Node.js, and PostgreSQL; I supported research preparation, validation, and documentation under mentor review. The team moved more of the intended audience into meaningful use; confirmed with my mentor that my contribution was limited to the assigned support and validation work.
• The team replaced synchronous report generation with queued jobs and progress recovery; I supported research preparation, validation, and documentation under mentor review. The team reduced repeat incidents from the same failure mode; confirmed with my mentor that my contribution was limited to the assigned support and validation work.
• Under supervision, owned a React and Java account-settings flow using SQL migration tests, resolved stale form submissions and released an end-to-end regression suite.
• Under supervision, built CI/CD checks using code-review findings and AWS preview environments, reduced repeated integration failures by 31% across six weekly releases.

• In a mentor-reviewed simulation, built a React order workspace backed by a Java API and SQL transactions; tested duplicate submissions and permission changes so an interrupted request could not create a second order.
• As a second supervised exercise, packaged the application in Docker and added CI/CD checks for schema compatibility and end-to-end checkout. Blocked promotion when an old client could no longer read the new response.
• Under supervision, the team introduced typed API contracts for 23 shared endpoints; I supported research preparation, validation, and documentation under mentor review
• Built an isolated fixture with normal, malformed and interrupted inputs; recorded the expected response before running the implementation so failures were distinguishable from a changed assumption.
• Packaged the reproduction steps, configuration and regression tests with the project; checked the instructions from a clean environment and documented the unsupported cases instead of claiming production readiness.
• Owned the independent regression fixture using isolated inputs, resolved a failing edge case and released a reproducible test package with expected outputs.

• Published an independent technical note using the project’s before-and-after traces, explaining the failed assumption, regression coverage and cases the implementation does not support.
