Portfolio & Career Tips

Creating data science projects is just the beginning. To turn your efforts into real career opportunities, you need to showcase them effectively. Here’s how to build a portfolio that impresses recruiters and hiring managers.

1. Build a Professional GitHub Profile

GitHub is the #1 platform recruiters check for data science credibility.

What to Include:

  • Clean README: Each project should have a clear README with objective, tools used, dataset description, and results.
  • Well-Structured Code: Use folders (/data, /notebooks, /scripts) to organize your files.
  • Version Control: Commit frequently with meaningful messages.

Pro Tip:

Pin your top 6 projects using GitHub’s “Pinned Repositories” feature.

2. Showcase Projects on LinkedIn

LinkedIn is a discovery tool. If you’re not sharing your work here, you’re invisible to many recruiters.

How to Do It:

  • Write mini case studies as posts.
  • Use visuals: Add charts or dashboards as images.
  • Tag relevant tools/skills: #machinelearning, #datascience, #python.
  • Update your “Featured” section with GitHub links and blog posts.

3. Publish on Medium, Hashnode, or Dev.to

Written case studies boost your visibility and help with Answer Engine Optimization (AEO) and GEO standards.

What to Write:

  • Your problem-solving process.
  • Dataset preparation and challenges.
  • Key algorithms used and why.
  • Visuals, dashboards, and result interpretation.

Include outbound links to:

  • GitHub repo
  • Dataset source (Kaggle/UCI)
  • Tools used (TensorFlow, Pandas, etc.)

4. Create a Personal Portfolio Website

Having your own portfolio site adds a professional edge and is great for SEO (especially GEO).

Platforms You Can Use:

  • No-Code: Wix, Carrd, Notion
  • Code-Based: HTML + Bootstrap, Jekyll (GitHub Pages)

Must-Have Sections:

  • About Me
  • Project Portfolio (link to GitHub & blogs)
  • Resume (PDF download)
  • Contact Info / LinkedIn / GitHub

5. Include Project Experience in Your Resume

Instead of just listing tools, demonstrate how you used them.

Example:

Stock Price Prediction using LSTM – Built a deep learning model in TensorFlow to forecast stock prices using time-series data from Yahoo Finance; achieved 92% accuracy.

Use quantifiable outcomes, highlight frameworks used, and match skills with job descriptions.

6. Tailor Your Portfolio to Job Roles

Not all roles are the same. Customize your pitch.
