+# Hi, I'm Kalana Hewapathirana 👋
+
+**Software Engineer & Computer Science Educator** · Colombo, Sri Lanka 🇱🇰
+
+BSc (Hons) Computer Science graduate working at the intersection of applied machine learning and education. I build end-to-end ML systems — data pipelines, model training, APIs, and dashboards — with a focus on NLP, computer vision, and document AI. Currently teaching Computer Science (Pearson Edexcel iLowerSecondary & IGCSE) while continuing to build and share ML work here.
+
+## 🔬 What I work on
+
+- **NLP & Text Classification** — Sentence Transformers and BERT-based classifiers for app review and complaint analytics
+- **Computer Vision** — CNNs for diabetic retinopathy detection, transfer learning with DenseNet121
+- **OCR & Document AI** — EasyOCR pipelines for digitizing handwritten records
+- **ML Engineering** — FastAPI, PostgreSQL, SQLite, Streamlit dashboards, embedding storage and retraining pipelines
+
+## 🚀 Featured Projects
+
+| Project | Stack | Highlights |
+|---|---|---|
+| **Diabetic Retinopathy Detection** | TensorFlow, custom CNN | 98% accuracy lightweight model; benchmarked against DenseNet121 with test-time augmentation |
+| **SLT Selfcare Bug Analytics** | BERT, Streamlit | Classifies Play Store reviews into bug categories, cutting manual triage time |
+| **Review Analytics Engine** | Sentence Transformers, Logistic Regression, SQLite | End-to-end complaint classification with a retraining pipeline |
+| **WiFi Router Localization** | Particle & Kalman Filters, FastAPI, Leaflet.js | Real-time RSSI/GPS positioning with live map visualization |
+| **Fiber Length OCR** | EasyOCR, Python | Automated extraction of handwritten fiber data into a queryable database |
