I’m a hands-on CTO and technical advisor with 20+ years of experience at Goldman Sachs, Credit Suisse, HSBC, and Deutsche Bank. I specialize in turning complex technical challenges into high-performing solutions that deliver real business results.
As a builder at heart, I’ve achieved measurable impact like reducing signal generation time from 90 minutes to 6 minutes (15x improvement) at a FinTech startup. Whether you need fractional CTO services, technical consulting, or engineering leadership, I connect your business goals with the right technology.
Tech Stack: Python, Java, C++, Rust, JavaScript, Go, R, plus AI/ML frameworks (TensorFlow, PyTorch), containerization (Docker, Kubernetes), and modern DevOps practices. I choose the right tool for every job.
Cloud & Infrastructure: Expert in AWS, GCP, and Azure with experience building high-performance trading systems handling millions of daily transactions with sub-millisecond latency. I’ve scaled engineering teams from 5 to 50+ developers while maintaining quality and velocity.
