About me

Turning architectural complexity into competitive advantage

With over a decade of hands-on experience designing distributed systems, microservices, and cloud-native platforms, I've helped startups and enterprise teams alike navigate the hardest parts of software architecture — the parts where a wrong decision costs months.

As a globally vetted Top 3% Software Architect, I've worked across a diverse range of industries and tech stacks, bringing clarity to system design, team structure, and technology choices. My approach is pragmatic: every architectural decision should serve the business goals, not the other way around.

Today I'm focusing my energy on consulting and training — sharing what I've learned building production systems and helping developers become the architects their companies need. I'm also deeply invested in the Generative AI revolution and specifically in training engineers to use Claude Code as a force multiplier in their daily workflow.
