Duplicate Data Cleanup Summary

Date: October 8, 2025

✅ Duplicates Removed from _data/cv.json

I found and removed duplicate data that was being maintained in two places. The website uses the dedicated collection folders (_certifications/, _publications/, _portfolio/), so I removed the duplicate entries from cv.json.

1. Certifications (REMOVED from cv.json lines 131-147)

• ❌ Removed: IBM Data Science Professional Certificate
• ❌ Removed: Reinforcement Learning Specialization
• ✅ Kept in: _certifications/ folder (actively displayed on /certifications/ page)

2. Publications (REMOVED from cv.json lines 186-229)

• ❌ Removed: 6 publications (Stabilizing Federated Learning, KACQ-DCNN, Lorentz-Equivariant, etc.)
• ✅ Kept in: _publications/ folder (actively displayed on /publications/ page)

3. Portfolio (REMOVED from cv.json lines 232-275)

• ❌ Removed: 6 portfolio projects (RAG System, Monte Carlo, YOLOv8, etc.)
• ✅ Kept in: _portfolio/ folder (actively displayed on /portfolio/ page)

📊 Current Data Organization

Data ONLY in Dedicated Collections (Single Source of Truth):

| Section | Location | Displayed On | Status | | —————— | —————— | —————— | ——————————- | | Certifications | _certifications/ | /certifications/ | ✅ Active | | Publications | _publications/ | /publications/ | ✅ Active | | Portfolio | _portfolio/ | /portfolio/ | ✅ Active | | Hobbies | _hobbies/ | /hobbies/ | ✅ Active | | Talks | _talks/ | /talks/ | ⚠️ Template Data (needs cleanup) | | Teaching | _teaching/ | /teaching/ | ⚠️ Template Data (needs cleanup) | | Books | _books/ | /books/ | ❌ Empty | | Posts | _posts/ | /year-archive/ | ⚠️ Template Data (needs cleanup) |

Data ONLY in cv.json (Unique, Not Duplicated):

• ✅ Basics: Name, email, phone, website, location, profiles
• ✅ Work Experience: Nimbus Research Bureau
• ✅ Education: Jahangirnagar University, Sylhet Cadet College
• ✅ Skills: Programming, ML/AI, Data Science, Web Dev, Research
• ✅ Languages: Bengali, English
• ✅ Interests: Research interests list
• ✅ Awards: 4 competition awards + Duke of Edinburgh
• ✅ References: Dr. Mohammad Abu Yousuf
• ✅ Extracurricular: Athletics, IEEE, etc.

🎯 What This Means

Before Cleanup:

Certifications: _certifications/ + cv.json (DUPLICATE ❌)
Publications:   _publications/  + cv.json (DUPLICATE ❌)
Portfolio:      _portfolio/     + cv.json (DUPLICATE ❌)

After Cleanup:

Certifications: _certifications/ ONLY ✅
Publications:   _publications/  ONLY ✅
Portfolio:      _portfolio/     ONLY ✅

cv.json now contains ONLY unique data:
  - Contact info, work, education, skills, awards, etc. ✅

🔍 Technical Details

Files Modified:

• _data/cv.json - Removed duplicate sections for certifications, publications, and portfolio

Files NOT Modified (Active Sources):

• _certifications/ibm-data-science.md ✅
• _certifications/rl-specialization.md ✅
• _publications/*.md (7 files) ✅
• _portfolio/*.md (11 files) ✅

✨ Benefits of This Cleanup

1. Single Source of Truth: Each piece of data exists in only ONE place
2. Easier Maintenance: Update certifications/publications/portfolio in one location
3. No Sync Issues: Won’t have mismatches between cv.json and collection folders
4. Cleaner Codebase: Reduced file size and complexity in cv.json
5. Better Organization: Clear separation of concerns

📝 Note on cv.json Usage

The _includes/cv-template.html exists but is NOT currently used on any page. The cv.json file:

• Contains unique data (work, education, skills, awards, references, etc.)
• Could be used for future CV page generation
• Could be used for external CV tools or exports
• Now contains NO duplicate data from the website collections

If you ever want to generate a CV page from cv.json, you can create a page that uses the cv-template.html layout.

🚀 Next Steps (Optional)

1. Remove template data from _talks/, _teaching/, _posts/ (as identified in WEBSITE_AUDIT_REPORT.md)
2. Add content or remove the empty Books section
3. Consider adding a CV page that uses cv-template.html if needed
4. Keep cv.json synced with any changes to work experience, education, skills, etc.

Result: Your codebase is now cleaner with NO duplicate data! 🎉
