Junior Software Engineer Resume Preview
- Built a task management web application using React and Node.js during a 12-week internship that was adopted by the 15-person marketing team for daily workflow tracking, replacing a spreadsheet-based process
- Wrote 120 unit tests using Jest for the user authentication and profile management modules, increasing code coverage from 45% to 82% and catching a password reset token expiration bug before it reached production
- Developed a Python script to automate weekly sales report generation from PostgreSQL, reducing the reporting process from 3 hours of manual SQL queries and Excel formatting to a single 5-minute cron job
- Fixed 35 bugs across the frontend and backend during the first 3 months, including a date formatting issue affecting invoice generation for 200+ customers in non-US locales
- Created a REST API endpoint for bulk user imports using Node.js and Express that validates CSV uploads, processes 5K records in under 10 seconds, and returns detailed error reports for invalid rows
- Participated in code reviews for 50+ pull requests, providing feedback on code quality and learning team conventions, while maintaining an average review turnaround of less than 4 hours
- Implemented responsive designs for 8 marketing landing pages using React and Tailwind CSS that matched Figma mockups across mobile, tablet, and desktop breakpoints with cross-browser testing on Chrome, Firefox, and Safari
- Built a search feature with debounced input and PostgreSQL full-text search that returns results from a 100K-record product catalog in under 200ms, improving the previous LIKE-based search that timed out on large queries
- Set up a Docker development environment with docker-compose for the team's local stack including PostgreSQL, Redis, and the Node.js API, reducing new developer onboarding setup time from 2 days to 30 minutes
- Completed a capstone project building a real-time chat application with WebSocket support serving 50 concurrent users, implementing message persistence, typing indicators, and read receipts
- Documented 12 internal API endpoints with request/response examples in the team wiki, which the support team referenced daily and which reduced the number of Slack questions directed at engineers by roughly half
