+# Serengo Finds Feature Implementation Log
+
+## Implementation Started: October 10, 2025
+
+### Project Overview
+
+Implementing the "Finds" feature for Serengo - a location-based social discovery platform where users can save, share, and discover memorable places with photos/videos, reviews, and precise location data.
+
+### Implementation Plan
+
+Based on finds.md specification, implementing in phases:
+
+**Phase 1 (MVP):**
+
+1. Database schema and migrations ✓ (in progress)
+2. Create Find functionality (with photos)
+3. FindsMap with markers
+4. FindPreview modal
+5. Basic Find feed
+
+**Phase 2:**
+
+- Video support
+- Like functionality
+- Friends system
+- Enhanced filters and search
+- Share functionality
+
+### Progress Log
+
+#### Day 1 - October 10, 2025
+
+**Current Status:** Starting implementation
+
+**Completed:**
+
+- Created implementation log (log.md)
+- Set up todo tracking system
+- Reviewed finds.md specification
+
+**Next Steps:**
+
+- Examine current database schema
+- Add new database tables for Finds
+- Set up R2 storage configuration
+- Create API endpoints
+- Build UI components
+
+**Notes:**
+
+- Following existing code conventions (tabs, single quotes, TypeScript strict mode)
+- Using Drizzle ORM with PostgreSQL
+- Integrating with existing auth system
+- Planning for PWA offline support
+
+**Update - Database Setup Complete:**
+
+- ✅ Added new database tables (find, findMedia, findLike, friendship)
+- ✅ Generated and pushed database migration
+- ✅ Database schema now supports Finds feature
+
+**Current Status:** Moving to R2 storage and API implementation
+
+**Required Dependencies to Install:**
+
+- @aws-sdk/client-s3
+- @aws-sdk/s3-request-presigner
+- sharp
+
+**Next Priority Tasks:**
+
+1. Install AWS SDK and Sharp dependencies
+2. Create R2 storage configuration
+3. Implement media processing utilities
+4. Create API endpoints for CRUD operations
+5. Build UI components (CreateFindModal, FindPreview)
+
+**Technical Notes:**
+
+- Using text fields for latitude/longitude for precision
+- isPublic stored as integer (1=true, 0=false) for SQLite compatibility
+- Following existing auth patterns with generateFindId()
+- Planning simplified distance queries for MVP (can upgrade to PostGIS later)
