Tech-Specific Tips

GitHub Profile Optimization

Make sure your GitHub shows:

• Pinned repositories (your best 6)
• Green contribution graph (activity)
• README for profile
• Complete project READMEs

Project READMEs should include:

• What the project does
• Technologies used
• How to run it
• Screenshots/demos
• Your contributions (for collaborative projects)

Dealing with Tech Stacks

If you match their stack:

• Lead with those technologies
• Quantify your experience with them

If you don't match exactly:

• Emphasize transferable skills
• Show learning ability
• Highlight similar technologies
• Example: "Django" → "Extensive Python web framework experience (Django); quick to ramp on new frameworks"

Technical Interviews Prep Note

Tech resumes should support your interview:

• Only claim technologies you can discuss deeply
• Be ready to explain every project listed
• Know the architecture of systems you've built
• Have stories ready for each bullet
