Nice to meet you, I'm Tomislav Pree
I'm an AWS Cloud Architect and tech consultant passionate about designing secure, scalable cloud platforms. Since 2019, I've taken systems from target architecture to production operations, always focused on automation, reliability, and cost efficiency.
How I found my way into the cloud
I discovered my passion for infrastructure while studying computer science in Mainz. My first projects ran serverless in 2019, and I was hooked: the idea that an entire platform can be described, versioned, and rebuilt from code changed how I think about software.
From first architecture to regulated platforms
In 2020 I designed my first AWS architecture from scratch: VPC segmentation, load balancing, autoscaling. Since then I've architected event-driven systems for e-commerce at scale, multi-tenant SaaS platforms, and MLOps and LLM inference platforms. Today I build and run Kubernetes platforms in a safety-critical, regulated environment.
Over 7 years of experience and 20+ projects
I've worked with some amazing companies
Cloud Architect & MLOps
Conceived and delivered the AWS target architecture end-to-end: multi-account setup, Terraform, MLOps pipelines, and LLM inference in production.
Cloud Architect & Data Streaming
Architected AWS solutions for e-commerce systems with millions of product pages, plus event-driven data processing with Kafka and Kafka Streams.
Cloud Architect & SaaS Platforms
Owned the architecture of a multi-tenant SaaS platform on AWS and GCP: tenant isolation, RBAC, and AI model serving.
Past education & credentials
Academic background in computer science and years of hands-on platform work shaped my approach to cloud architecture and system design.
