I’m Rastko — Head of Architecture, technology strategist, and engineer. 20+ years building software, the last 6+ years at Director level inside adidas Digital, one of the world’s largest mono-brand digital platforms.
My current scope is adidas.com, the adidas App, adidas Confirmed, and adidas Running. I lead a team of 10 senior architects and act as primary technical advisor to senior leadership across the area.
I operate at enterprise architecture level while keeping an active hands-on engineering practice. I write code, build hardware, maintain open-source tooling, and think in systems from the circuit board up — embedded systems through cloud-scale architecture through organizational strategy.
Engineering
Software architecture: TOGAF ADM, evolutionary architecture, C4 modelling, risk-driven design, domain-driven design
Electronics: complete systems from schematic to firmware — PCB design, soldering, hardware prototyping, ESP32/Arduino/embedded development
Software: JavaScript, TypeScript, Python, Bash, C/C++, Linux, Kubernetes, observability, AWS, GCP
AI: LLMs, AI agents, RAG — building and using AI tools and practices
I built quantum-toolbox — an open-source AI agent toolkit that encodes architectural thinking as executable mental models. 27+ skills covering the full architecture spectrum: TOGAF ADM phases, C4 modelling, security analysis (OWASP, NIST, NIS2, ISO 27001), fitness functions, and structured output generation. Pure markdown, ships as a git submodule into any project.
Within adidas I run an AI community of practice that helps engineers and architects adopt AI-assisted workflows in the reality of brownfield enterprise systems — where the constraints are real and the productivity gains are harder-won.
