/how-i-build

I will make your systems talk — reliably and resiliently.

< Sync & Async processing />

I build REST APIs and cloud event-driven ecosystems.

// 01 sync & async

< Resilient />

I use retries, idempotency and other strong patterns to keep systems working even when a failure occurs.

// 02 resilient

< Scalable />

I split systems into independent, loosely coupled microservices or modules that you can deploy, scale and introduce new versions separately.

// 03 scalable

< Observable />

I add logs, telemetry and alerts so you know about problems in advance, before your clients do.

// 04 observable

/problem-solving

Problems I deal with and can solve.
