Hi, I'm Dawid Ryłko

Solution Architect | Cybersecurity

I design system architecture and own its security. I have worked in IT for a long time, across the whole stack: frontend interfaces, backend services, infrastructure automation, AI integration, and cybersecurity.

I weigh technical decisions against business goals and the cost of running a system for years.

What I do

  • System architectureDesigning whole systems and platforms, from a single service to a complete environment, and setting their technical direction. The hard part is what a system costs to keep running, not what it costs to build.
  • CybersecurityThreat modelling, security reviews, and hardening, done while the design is still on the table rather than after the first incident. Access control, data handling, and the way a system is deployed and monitored all count.
  • Full-stack engineeringFrontend, backend, and mobile in whatever stack the problem calls for: TypeScript and JavaScript, React, Angular, Ionic, Node.js, Python, and others.
  • Infrastructure and deliveryCI/CD and cloud infrastructure, plus the production environments and monitoring that come after the release.
  • AI agents and automationLLMs, MCP, and multi-agent workflows put to work on real engineering tasks.
  • Engineering leadershipLeading a team, owning a product, and setting the standards other teams build against.
