BloodAI is an end-to-end clinical triage system that bridges the gap between a confused patient and an overworked doctor. 

PROBLEM: In Poland, doctors have 7 minutes per patient. 47% of patients don't understand their lab results. Wait time for a specialist on public insurance is 3-18 months.

SOLUTION: Photograph your lab report. In 10 seconds:
- Opus 4.7 Vision extracts 9 lab parameters
- Custom BERT model (18MB, trained from scratch on 408,214 Synthea+MIMIC sequences) performs 8-class triage with calibrated probabilities (ECE 0.012)
- 52 vocab-aware adaptive questions empirically shift predictions by up to 37 percentage points
- Opus 4.7 generates patient-mode (plain language) and clinical-mode (structured assessment) explanations
- 37 personalized follow-up tests recommended with 14 conditional rules
- Real doctor finder integrates live NFZ public health in Poland API + Google Places for private clinics
- Trend analysis with 6 cross-parameter comorbidity detectors (CKD progression, pancytopenia, etc.) with R^2 up to 0.99

13 live endpoints. Zero mocks. Built solo in 36 hours.
