AI R&D and Machine Learning
Novel model development, failure diagnosis, and GPU-to-CPU conversion to reduce deployment costs. Experience in speech recognition achieving 3.64% WER on Common Voice German, optical flow AI, and self-play reinforcement learning squeezed to CPU-only inference.
High-Performance Systems and Performance Optimization
3-day sprints to identify and fix bottlenecks, reduce hardware usage, and deploy cost-efficiently. Expertise in NEON/AVX-vectorized DSP, real-time audio processing of 500+ audio channels, and kernel-level optimization.
Scalable Web Crawling and Computer Vision at Scale
Architecture of web crawling stacks with 5,000+ concurrent crawler tasks orchestrated with Ansible, distributed C++ content-based image retrieval databases scaling to billions of web images, and all internal AI filters for image enforcement workflows.
Fractional CTO Leadership
Senior tech leadership available a few days a month without the overhead of a full-time executive. Covers architecture decisions, team guidance, and technical strategy for EU and US clients.
Real-Time Audio and DSP
Development of real-time routing and panning engines, VST/RTAS/AU/AAX plugins, and virtual sound card kernel drivers for Mac and Windows, used by Hollywood studios.
Embedded Systems and Kernel Development
Kernel driver development, ARM version builds for embedded systems, smartphones, and VR headsets, as well as GPU driver-level debugging across the full Linux stack.
Technical Due Diligence
Code-level review of technology stacks to identify execution risks on the tech side, going beyond pitch decks to assess real implementation quality.
Distributed Systems and Workflow Automation
Design and implementation of distributed systems and workflow automation pipelines, including orchestration with Ansible and automation that turned image enforcement into a production product.
Programming and Technology Stack
Proficiency in C++, Python, CUDA, PyTorch, TensorFlow, Linux, NEON/AVX, kernel drivers, PostgreSQL, Docker, Ansible, and Ruby on Rails.
