This is your portfolio centerpiece - the project that shows employers what you can do. A polished, deployed application demonstrates all your skills working together and proves you can finish what you start.
You'll learn project planning and architecture. Deciding how to structure code, which technologies to use, and how features fit together - these decisions matter. This project teaches you to think like a senior developer.
Deployment and documentation are often overlooked but crucial. Employers want to see working applications, not just code on GitHub. A deployed project with good documentation shows professionalism and attention to detail.
This is your portfolio centerpiece. It combines everything you've learned into one complete application. This is what you'll show to employers to demonstrate your skills.
Building something from scratch to deployment teaches you the full development lifecycle. You'll make architecture decisions, handle challenges, and see a project through to completion.
This project proves you can work independently and build real applications. It shows you understand how all the pieces fit together, not just individual concepts.
Build a complete production-ready application that combines everything you've learned. This is your portfolio centerpiece that demonstrates your full range of skills to potential employers. Choose a project that solves a real problem and showcases your technical abilities.

Project demonstrates growth from earlier projects
Week 1: Planning, design, database schema, project setup
Week 2-3: Core backend implementation and testing
Week 4-5: Frontend development and integration
Week 6: Polish, optimization, bug fixes
Week 7: Documentation, deployment, testing in production
Week 8: Final touches, demo preparation
Hint: Don't try to build everything at once. Start with core features and get them working perfectly. Add nice-to-have features only after the foundation is solid. A polished MVP beats an unfinished feature-complete project every time.
Document as you go, not at the end. Write README sections when you implement features. Take screenshots throughout development. Your future self will thank you.
