- REST API integration, frontend debugging, and Redux-based state management
Selected Work
Projects
AdaptiveRTC_PTT
Open Source
C++17 · Kotlin · Jetpack Compose · KMP · Android JNI · CMake · BLE · Wi-Fi Direct
- P2P walkie-talkie Android app — devices discover each other over BLE, negotiate a Wi-Fi Direct UDP link, and exchange real-time audio with zero server required
- C++17 voice engine (ECSDetector, RTTTracker, RateController) detects congestion before packet loss via RTT trend analysis; adaptive jitter buffer with 40–120 ms dynamic playout
- End-to-end encrypted: ECDH (EC P-256) key exchange + AES-128-GCM; every BLE message carries a unique 12-byte nonce — plaintext never sent over the air
Explainable AI for Predictive QoS
Open Source
Python · scikit-learn · SHAP · Streamlit · pandas · NumPy
- Closed-loop analytics pipeline for proactive QoS assurance in IMS-based 5G networks (VoLTE/VoNR) — predicts degradation before severe user impact
- RandomForestClassifier on synthetic telecom KPIs (latency, jitter, packet loss, throughput); SHAP-based per-prediction explainability surfaces dominant degradation factors
- Streamlit dashboard with multi-seed experiment runner; exports decision recommendations as operator-ready action hints for NOC workflows
netSenseAI
Open Source
Kotlin · Kotlin Multiplatform · Jetpack Compose · Android · BLE · GATT
- Android-first peer discovery and messaging prototype — devices find each other over BLE, establish a GATT-based connection, and exchange text payloads in real time
- KMP shared logic layer with a Jetpack Compose UI; BLE scan/advertise pipeline with UUID filtering, RSSI display, OEM fallback compatibility, and runtime permission handling
- Live mesh state and event telemetry feed in UI; architecture foundation for adding encryption, ACK/retry, and Wi-Fi Direct transport
DevStreak
In Progress
Kotlin Multiplatform · Android · iOS · Web · AI
- Solves inconsistent developer skill-building — most tools lack the momentum mechanics that drive sustained growth
- Daily challenges + XP system with AI-powered feedback on code submissions; coroutine-based state management
- Single KMP codebase targeting Android, iOS, and Web — scalable modular architecture from day one
