WHAT THIS PROJECT PROVES
Make the engineering visible.
This brief is designed as portfolio evidence for a Full-Stack Developer path. The goal is not to claim a hiring outcome; it is to make your implementation, judgment and tradeoffs easier to inspect.
APIs
Show where APIs affected a real decision in the project. Include the implementation, constraint, test or measurement that makes the skill verifiable.
SQL
Show where SQL affected a real decision in the project. Include the implementation, constraint, test or measurement that makes the skill verifiable.
Search
Show where Search affected a real decision in the project. Include the implementation, constraint, test or measurement that makes the skill verifiable.
Auth
Show where Auth affected a real decision in the project. Include the implementation, constraint, test or measurement that makes the skill verifiable.
BUILD PLAN
Finish the core before expanding the scope.
Use this as a project sequence, not a rigid tutorial. Your stack can change; the evidence should still show what you built, why you built it that way and how you know it works.
Define the scope and success criteria
Turn the brief into a small finishable system. Decide what the core Two-Sided Marketplace MVP must do, what you will deliberately leave out, and how you will show that it works.
Build the core workflow
Build listings, search, saved items, messaging and role-specific workflows. Keep the first pass focused on the main user or system flow before adding stretch features.
Add engineering proof
Create live marketplace and seed data. Document the decisions, failure states, tests, performance, security or operational tradeoffs that matter for this project.
Ship and package the evidence
Publish the strongest artifacts, including schema diagram, role flows, test plan. Make it easy for a reviewer to understand the problem, architecture, tradeoffs and what you personally implemented.
PORTFOLIO PROOF CHECKLIST
Leave artifacts a reviewer can inspect.
A strong project page should make it possible to understand the system without guessing what you personally built.

RESUME / PORTFOLIO FRAMING
Describe what you actually did.
Shipped a two-sided marketplace with authenticated role workflows, search, persistence and deployment.
Use this as a starting structure, then replace it with your real implementation details, metrics and constraints. Do not claim outcomes you did not measure.
INTERVIEW TALKING POINTS
Be ready to defend the decisions.
These prompts turn the project from a repository link into a technical conversation about judgment, tradeoffs and evidence.
Why did you choose your approach to React, and what alternative did you reject?
Answer with details from your implementation. Prefer concrete constraints, measurements and alternatives over generic best practices.
Where could Two-Sided Marketplace MVP fail under real usage, and how would you detect or recover from that failure?
Answer with details from your implementation. Prefer concrete constraints, measurements and alternatives over generic best practices.
How did APIs affect the rest of the design?
Answer with details from your implementation. Prefer concrete constraints, measurements and alternatives over generic best practices.
What did you measure or test to prove Auth instead of only claiming it?
Answer with details from your implementation. Prefer concrete constraints, measurements and alternatives over generic best practices.
If you had one more week, what would you improve first and why?
Answer with details from your implementation. Prefer concrete constraints, measurements and alternatives over generic best practices.
STRETCH GOALS
Go deeper only after the core is solid.
Payments sandbox
Add it only if it strengthens the engineering story instead of delaying a finished, deployable core.
Moderation
Add it only if it strengthens the engineering story instead of delaying a finished, deployable core.
Recommendations
Add it only if it strengthens the engineering story instead of delaying a finished, deployable core.
RELATED PORTFOLIO PROJECTS
Build another signal in the same path.
Choose another project only when it proves a different part of the role instead of repeating the same evidence.
