About Jiri
I help startups, fintechs and growing companies design secure, scalable and cost-efficient AWS platforms and system architectures for new and existing products.
I have 10+ years of hands-on experience as a CTO, building and operating production systems with real users, real business impact and strict security requirements.
My work combines cloud architecture, security, operational reliability and practical business thinking. I focus on solutions that are technically strong, secure by design and realistic to build, run and scale.
Typical missions I take on include:
- AWS architecture reviews
- system and solution architecture for new software products
- cloud security audits and IAM hardening
- cost optimisation / FinOps reviews
- migration and refactoring guidance
- CTO-level cloud advisory
I also use AI-enabled engineering workflows and practical AI integration where it brings real value to delivery speed, analysis or internal automation.
I prefer project-based work with clear scope, ownership and measurable output.
