Freelance Senior Solutions Architect helping companies design, harden, and scale their data, cloud, and AI platforms – without blowing up cost or complexity.
With 15+ years of experience (including a PhD in numerical optimization & AI and 10 years in HPC), I step in when performance, reliability, and scalability really matter: architecture, audits, migrations, SRE, datalakes, IoT, Big Data, high availability, and production incident fatigue.
🧠 What I bring to tech teams & CTOs
Fast diagnosis of performance, scalability, and cloud cost bottlenecks
Design / review of data & AI architectures (Spark, Kubernetes, MinIO, Cassandra, Ceph, etc.)
Taking systems from POC to production, capacity planning, and cost optimization
Targeted support: flash audits, short missions, and coaching for engineering teams
