Distributed systems veteran, open source strategist, and hands-on technology leader with over two decades of real-world impact.
I’ve spent my career leading critical-path teams in cloud computing, distributed systems, and open source. Former OSPO lead, Scala developer advocate, and seasoned SRE manager with a deep focus on operational maturity, resilience, and technical clarity.
These are mini-books. They’re structured, multi-chapter deep dives designed to walk you through a given topic from first principles.
Lighter reads, quick hits, and notes from the field dating from 2009 until now.
Deterministic state evolution is not enough once your event broker provides at-least-once delivery. Idempotence, commutativity, and associativity are the three algebraic properties that protect state-transition functions against duplicates, reordering, and batched folds.
Most event sourcing tutorials teach developers to store events instead of current state, and stop there. Let's go deeper. Automata theory explains why event sourcing works, what properties transitions need, and what breaks under replay.
AI-assisted development accelerates dependency coupling. Onion Architecture, enforced by a strong build system, makes the compiler a structural bodyguard that catches architectural violations at compile time.
I also create content on YouTube and speak at various conferences. Check out a few highlighted videos below.
In 2017 I published a mini-book with O’Reilly to help architects and developers navigate cloud migration projects, based on lessons learned from real-world projects. This guide covers many important topics to consider before undertaking a complex cloud migration project, including:
Many of these lessons are still relevant in 2025 as more and more on-prem workloads are migrated to cloud and virtualized infrastructure.
