Senior Software Engineer (Contractor), Software Engineer, Software Engineer

Participated in the large scale (140 people) project for a networking solution which is revolutionizing the fiber internet service industry. The software involved two major systems both built on a reactive microservices message driven actor based architecture - one with Java, Akka Streams, MongoDB and Kafka, and the other using Go, PostgreSQL and NATS. The different microservices were containerized through Docker and deployed to different Kubernetes clusters both on premise and hosted on AWS.

-Engaged mainly in the full stack development of a scalable, high throughput web application used to create,
modify and instantiate in bulk different insurance domain objects such as contracts and policies inside Allianz
Business platform solution for insurance companies. Front-end was implemented through Angular, while the
back-end was developed with Spring Boot. Build an automated continuous delivery pipeline for the project in
Gitlab. The different microservices were containerized through Docker and deployed to a Kubernetes cluster
hosted on AWS.
Occasional development and support of other web applications based on the same technological stack and
similar architecture

-Worked on the development and support of the applications responsible for interactions between warehouse
workers and the highly automated warehouse robotic grid used to store and retrieve different products including
groceries (https://goo.gl/fgFr1X). Our applications were built on top of reactive message driven microservices
architecture implemented through the Akka actor model. They included a stateless controller responsible for
serving tasks to the users and a stateful application communicating with the automated warehouse and utilizing
event sourcing and CQRS architecture. All of the applications were containerized through Docker and deployed
to Kubernetes

-Participated in the implementation of an event-routing application consisting of a producer and a consumer
part. The producer app would receive JSON events through an HTTP REST endpoint and route them to certain
Kafka topics based on predefined rules. The consumer component would consume messages from the Kafka
topics and send them to another set of HTTP endpoints. All of the applications were containerized through
Docker and deployed to Kubernetes
Technologies: Java, Spring Boot (web, kafka, Tomcat), Apache Kafka, Kafka Manager, Gitlab, Docker,
Kubernetes, JUnit, Prometheus, Grafana, ELK, Maven, Helm

-Involved in the work on a web application used to configure, store and retrieve configuration information
about the bots running over the warehouse robotic grid and the wireless stations responsible for communication
with the bots. Used Swagger to document the API of the backend and to generate code for the Angular frontend
which would call the backend API. All of the applications were containerized through Docker and deployed to
Kubernetes
