Description

Backend Engineer with strong specialization to achieving great code quality, scalability & high-performance by utilizing AWS cloud technologies. SonarQube, S3, Lambda, Elasticsearch, DynamoDB, EKS & KMS are the tools I use on a regular basis.

With the power of Datadog & Kibana when using REST & Kafka communication between the microservices implemented in Java, Python or NodeJS I am able to smoothly monitor the flow of packets and accurately pinpoint any inefficiencies, critical bugs & misconfigured components / microservices.

Next to all of these technical skills I am very talented incommunicating the business requirements with international clients & managing software development teams.
