ML Engineer — Defense CV · Open Source · Systems from Paper to Production
Building real-time computer vision systems for defense at DeepEdge. Contributor to PyTorch Lightning, Hugging Face, and KerasCV/NLP. LinkedIn LIFT Scholar 2022 (Top 500 technologists globally, 0.5% acceptance).
Anti-UAV Tracking @ DeepEdge — End-to-end production system deployed at 3 defense installations, processing infrared video in real-time on NVIDIA Jetson edge devices.
- Sub-pixel tracking ensemble (Lucas-Kanade + TAPNet + CoTracker) extending detection range 1.5km → 5km — contributed to $2M+ contract renewal
- Hybrid CV pipeline (YOLOv8 + Kalman + MOG2/SVM): 95%+ accuracy, 80% false positive reduction
- 4.2x inference speedup (250ms → 60ms) via TensorRT quantization + CUDA kernel fusion for 30fps edge deployment
- 3D world-frame localization: monocular depth + camera calibration + IMU fusion → <0.5m error

| Unify.ai (Ivy) | — | Built 15+ TensorRT OpConverters, 3x faster inference, 40% memory reduction |
From-scratch implementations of key deep learning papers in PyTorch. Not wrappers — actual algorithm reimplementations to understand the math.
vector-db — Custom Vector Database
HNSW graph-based approximate nearest neighbor search, built from scratch in Python with minimal dependencies. No LangChain, no Pinecone — just NumPy and the algorithm.
flight-scanner — RAG Flight Analytics
Natural language queries over structured flight data using DeepSeek-R1 (70B) + LLaMA 3.2 (3B) with RAG architecture, ChromaDB, and FastAPI.
amazon-classification — Large-Scale Product Classification
Fine-tuned ALBERT on 500K Amazon listings across 27 categories with 1:150 class imbalance. 89% F1 — beat BERT by 12% and the production baseline by 10%. Deployed with TensorRT.
childmind-prediction — ChildMind Anxiety Prediction
Gated RNNs analyzing children's physical activity patterns for early detection of problematic internet use. Healthcare ML with real clinical relevance.
food-delivery — Full-Stack Delivery Platform
Django REST + JWT auth. Vendor management, proximity search, payment integration, real-time order tracking, push notifications. Shows I build complete products, not just models.
