BIO
Damian specializes in fault-tolerant, event-driven systems using Node.js, PostgreSQL, and modern messaging. His MSc background gives him a unique view on technical and business requirements.
A strong advocate for Hexagonal & Clean Architecture, Damian ensures codebases remain maintainable as they scale. His decisions consistently produce systems that evolve without rewrites.
At Sky Gate he rewrote a legacy SOAP monolith into a microservices mesh serving 12M API calls/day, which enabled the company to scale operations significantly.
At CloudFloo, Damian architects the backend foundation of modern applications — high load, consistent data, reliable systems.
