I'm a Web3 lover, passionate about challenges and with years of software development experience. My main language is Go, and I work with PostgreSQL, DynamoDB, and Elasticsearch. I follow SOLID and TDD, design patterns, and I actively practice CI/CD with automated pipelines. I build observability into all my systems using tools like OpenTelemetry, Datadog, Grafana, and O11y, and I rely on distributed tracing and chaos engineering to improve resilience. I design and operate infrastructure as code with Terraform, Kubernetes, Argo CD, and Helm. I believe nobody knows everything, and there is always more to learn. Empathy is the key to being an ideal team player. Learn more about my work with Web3 in the Payfely DApp at payfely.com.
