Portfolio vs Resume for Tech Jobs: Do You Need Both?
You need both, and they do different jobs. Your resume clears the ATS filter. Your deployed project is the part a recruiter can open in a browser and check.
By Howard Davner
💡 Quick Answer: You need both, and they do different jobs. Your resume exists to clear the applicant tracking system and survive a recruiter's quick scan. Your portfolio, specifically a project deployed at a live URL, is the part someone can open and check for themselves. A resume without projects is a list of claims. Projects without a resume that clears the filter never get seen.
Students ask whether to focus on the portfolio or the resume, as if the two compete for the same slot. They do not. They work at different stages of the same process, and skipping either one costs you the other.
Here is what each one actually does.
What a Resume Does
Your resume has one job: get you past the filter.
That filter is usually an applicant tracking system, which parses your resume, matches it against the job description, and decides whether a person ever opens it. Adoption is high among mid-size and large employers and considerably lower among small businesses, and published survey figures vary a lot depending on who was asked, so treat the exact percentage as unknowable and the general point as reliable: if you are applying to a company with a real HR function, assume software reads your resume first.
Once it reaches a person, the scan is short. The Ladders eye-tracking study, the most-cited primary source on this, put the initial review at about 7.4 seconds on average when it was updated in 2018. Whatever the current number, the design implication has not changed. A reviewer is looking for role alignment, relevant tools, and anything that separates you from a stack of near-identical applications.
What a resume cannot do: show that you can build the thing. "Proficient in Python." "Strong data analysis skills." "Experience with machine learning." Those are assertions, and every competing resume asserts the same. Nothing in the document lets a reader confirm any of it.
What a Portfolio Does
A portfolio, specifically a project deployed at a live URL, covers exactly that gap. It gives the reviewer something to check instead of something to believe.
A portfolio project that does this well has three properties:
- It is deployed. A URL that opens in a browser, not a repository that has to be cloned and run.
- It is relevant. Built for the kind of role you are applying to, not a generic tutorial project.
- It is yours. You made the design decisions and you can explain them. Using AI to build faster does not change that, but being unable to explain your own architecture does.
What a portfolio cannot do on its own: get past the filter. If the resume does not clear the ATS, the link is never opened. This is the part students underestimate, and it is covered in more detail in what employers actually look for in a CS portfolio.
Why the Either/Or Framing Fails
Resume only: all the effort goes into tailoring, the application clears the filter, and then the reviewer has no way to tell you apart from the other candidates who also cleared it. You have optimized for a stage you already passed.
Portfolio only: projects get built, usually undeployed and usually not aimed at any particular role, and the untailored resume gets filtered before anyone reaches them. The work was real and nobody saw it.
The combination that holds up is a resume tailored enough to clear the filter plus one deployed, role-specific project that gives the reviewer something verifiable. Neither half is impressive alone. If the choice in front of you is narrower than that, an afternoon with a resume builder against a weekend building something, here is how to sequence the two.
The Specific Setup
Resume, for the ATS and the recruiter scan:
- Language from the job description, used the way the posting uses it
- Single-column formatting, no tables or graphics that confuse parsers
- A Projects section listing the deployed project with its live URL
- One or two sentences per project: what it does, the stack, the link
Portfolio, for the human reviewer:
- One deployed project built for this type of role
- A live URL rather than a repository link, since a repo is a reading assignment and a URL is a click
- A short project page explaining the problem it solves
- Code on GitHub as the secondary reference
That last point is the one most worth internalizing, and it is the whole argument of why GitHub is not a portfolio.
Where to Deploy It Free
Free hosting tiers change often, so verify before you rely on one. As of September 2026:
- Vercel Hobby is free and intended for personal, non-commercial projects, which covers a student portfolio.
- Render offers free web services, but they spin down after roughly 15 minutes of inactivity and take about a minute to restart on the next request.
- Hugging Face Spaces has a free CPU tier that sleeps after 48 hours without visitors.
The sleep behavior matters more than it sounds. A reviewer who clicks your link and waits a minute at a blank screen may not wait. If you are using a tier that idles, open the link yourself before you send the application, and consider the always-on option for the project you lead with. More on presenting it well in how to put a deployed project on your resume.
By Role
Software engineering: something that shows API integration, sensible structure, and a working deployment. A code review assistant, PR summarizer, or semantic search tool reads as more considered than another CRUD app.
Data science and ML: a deployed model with an interface someone can use, rather than a notebook. A churn predictor or a sentiment dashboard shows the whole path from data to product.
Product and business: a tool aimed at a real business problem, such as a brief generator or a meeting summarizer, which demonstrates both building and judgment about what is worth building.
Marketing and comms: an AI tool inside a marketing workflow, such as an email analyzer or a content calendar generator, which shows domain understanding alongside the build.
Doing Both Without It Taking Weeks
The project is the part most students skip, because building and deploying something takes longer than editing a document. The tailoring is the part most students do once and then reuse for fifty applications.
Provieo takes a job description and produces both: a resume tailored to that posting's language and requirements, and a set of project ideas specific to that role, one of which you build and deploy to a live URL. The link goes straight into the resume's Projects section.
Provieo is free to use, and your first project build and deploy is free. After that it is $39 once for unlimited deployed projects, with no subscription.

Frequently Asked Questions
Do you need a portfolio and a resume for tech jobs?+
You need both, because they work at different stages. The resume is what an applicant tracking system parses and what a recruiter scans, so without it nothing else gets looked at. The portfolio is what someone can open and use once you are past that stage. A resume is a list of claims about your skills. A deployed project is a claim anyone can check in a browser.
Is a portfolio more important than a resume for tech jobs?+
Neither replaces the other. A portfolio cannot help you if the resume never clears the filter, because nobody sees the link. A resume on its own gives a reviewer nothing to verify, since every applicant writes the same skill bullets. The practical answer is to spend enough effort on the resume to clear the filter, then put the remaining effort into one project that is actually deployed.
Do tech recruiters actually look at GitHub portfolios?+
Some do, but a GitHub repo asks the reviewer to read code, clone it, or run it locally, and most reviewers will not spend that time on a first pass. A live URL asks for one click. If you have both, lead with the deployed link and keep the repo as the secondary reference for anyone who wants to read the code.
What should a tech portfolio include?+
One to three deployed projects with live URLs, each built for the kind of role you are applying to, plus a short description of the problem each one solves and what you built. Quality matters more than volume here, because one working deployed tool gives a reviewer something concrete and five undeployed repos give them a reading assignment.
Where can a student deploy a portfolio project for free?+
Vercel Hobby is free for personal, non-commercial projects. Render offers free web services, though they spin down after about 15 minutes of inactivity and take roughly a minute to wake. Hugging Face Spaces has a free CPU tier that sleeps after 48 hours without visitors. All three are free as of September 2026. Check whether your link is awake before you send it.
Put a working link in your next application.
Paste the job you're applying to. Provieo designs a project against that exact listing and walks you through deploying it, so what a recruiter clicks is the work itself, not a description of it.
Free to use, and your first deployed project is free. Or tailor your resume to the same posting.
