Technical Metrics to Include
Scale:
- Users: "serving 500K DAU"
- Requests: "handling 10K requests/second"
- Data: "processing 50TB daily"
- Uptime: "maintaining 99.99% availability"
Performance:
- Latency: "reduced from Xms to Yms"
- Speed: "improved by X%"
- Load time: "decreased by X seconds"
Efficiency:
- Cost: "reduced AWS costs by 40%"
- Time: "cut deployment time from X to Y"
- Resources: "reduced memory usage by X%"
Business:

Tech-Specific Tips
GitHub Profile Optimization
Make sure your GitHub shows:
- Pinned repositories (your best 6)
- Green contribution graph (activity)

- 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
