Figure 1. Channel Local Contrast for Breast Lesion Segmentation. Sixty-four learned gates on the fused YOLO26n mask-prototype feature — U′ = U + tanh(g)·(U − AvgPool₃ₓ₃(U)), with g = 0 at start — raise breast-ultrasound Dice on four datasets while the backbone, detector, mask coefficients and loss stay unchanged.

Figure 2. Experimental Android JCA Backend for webcrypto.dart. A native Android backend for Dart’s official Web Crypto package, built for Google Summer of Code 2026: bridging Dart to Android’s Java Cryptography Architecture with jnigen removes the 300–500 KB per-ABI cost of bundling BoringSSL, and early benchmarks on seven devices show up to 29× faster hashing for large payloads.
Figure 3. TeleOTIVA. Mobile, AI-assisted screening for precancerous cervical lesions from cervicography images — tested directly on 1,611 women aged 20–50 at Dr. Mohammad Hoesin Hospital Palembang and twelve primary health centres.
Figure 4. FazScan. A cross-platform website information and security scanner for Android, Windows and Linux, built with Flutter — developed as a research project for the Asia-Pacific Conference of Young Scientists 2022 in Computer Science.
Figure 5. Flutter Secure DotEnv. Encrypts environment keys for Flutter and Dart with AES, generated at build time — reliable key management and secret decryption so values in dotenv files stay confidential.
Figure 6. RF-DETR. Open-source contributor to RF-DETR, Roboflow’s real-time detection transformer for object detection and instance segmentation — seven merged pull requests, credited in releases 1.6.4 to 1.9.0.
