May 2026 monthly summary for roboflow/inference focusing on security, stability, and deployment performance. Implemented opt-in HTTPS for self-hosted inferences via TLS environment variables, consolidating launch paths across container entrypoints and improving security/compliance with minimal customer disruption. Reworked Jetson Docker images to enable hardware-accelerated video capture by building OpenCV from source with GStreamer and FFmpeg, embedding NVIDIA plugins, and introducing BuildKit cache mounts and CI workflow updates to accelerate and stabilize builds. Addressed a broad set of runtime and build-time issues in OpenCV/Jetson integration, including cv2 import reliability and loader path resolution, and tightened build hygiene with per-platform ARG controls and runtime checks. Modernized CI/CD with latest GitHub Actions and cache strategies, and established per-build-tree caches via Depot projects to ensure fast, repeatable builds. Overall, these changes deliver improved security for self-hosted deployments, faster and more reliable Jetson-based deployments, and a stronger, more maintainable build system with measurable business value.

November 2025 monthly summary for roboflow/inference focusing on delivered features, reliability improvements, business impact, and technology skills demonstrated. Highlights include the Jetson-Optimized Inference Stack (from-source builds for PyTorch, torchvision, and ONNX Runtime with numpy 2.x support) delivering measurable runtime and memory gains, and OPC UA Writer Reliability Enhancements introducing connection pooling and a circuit-breaker pattern for faster recovery and higher resilience. Key commits anchor traceability to the work performed. Key achievements: - Jetson-Optimized Inference Stack: from-source compilation for PyTorch 2.8.0 with Jetson Orin optimizations, CUDA/TensorRT integration, and memory optimizations. Results: 65.7 FPS (baseline 62.2 FPS, +5.6%), image size reduced to 6.74GB (baseline 8.28GB, -18.6%). Storage and memory savings include ~2GB from cuDNN/TensorRT symlinks and ~500MB from cleanup of non-public APIs and dev/test assets. Additional optimizations include FP16 TensorRT, engine caching (2GB), builder optimizations, and memory-efficient auxiliary streams. Commits: f26bf0ae2d0c09ce88c59a67d4f85d46087f6fc3. - OPC UA Writer Reliability Enhancements: added connection pooling via OPCUAConnectionManager with a circuit breaker to fail fast on server outages; recovery improvements with reduced timeout and more retries. Updated defaults: circuit breaker timeout 2s, max_retries 3, retry_backoff 15ms. Refined error handling using asyncua exception types and extended numeric type support. Commits: 82e1cd6fc3e8fad7bd4b5d529829e925945d4530, 3cf71707b6373e2a56742234dac4226bfc8c08fa, b6500d0a42dcb9904821c33f18dd996def0f1432. - Code quality and stability: Black formatting fix to improve consistency and reduce review cycles. Impact and business value: - Increased inference throughput and reduced memory footprint on Jetson devices enable higher batch concurrency and more deployments per device, driving operational efficiency and lower hardware costs. - Improved reliability and recoverability of the OPC UA writer reduces pipeline downtime and speeds up data delivery in edge deployments, increasing overall system resilience and SLA compliance. - Demonstrated proficiency in embedded optimization, high-performance compute, asynchronous error handling, and robust retry strategies, aligning with platform reliability and performance goals.
