I was able to contribute in all areas: infrastructure, frontend/backend development, and requirements research.⭐️ Hired and trained interns, participating in all stages of the hiring process, from CV screening to defining code standards, code review processes, and fostering a DevOps culture.⭐️ Reduced our AWS billing by 60%, through the containerization of our microservices and design/implementation of a VPC network.⭐️ Integrated our CRM with a plethora of platforms: Hubspot, telecommunications platforms and Teams. We are proudly able to support multiple integrations with minimal support staff, through the use of extensive observability.Employed the latest industry standards to completely migrate our microservices infrastructure to a containerized environment using ECS and Fargate. Architected and implemented network cloud infrastructure for a highly available financial market system. Significantly increased system observability by integrating modern tools like OpenTelemetry and Datadog. Show less

⭐️ I’ve been able to reduce our AWS billing by 50%, through proper scaling of existing services and the deployment of auto scaling actions in our ElasticBeanstalk and Amazon RDS services. ⭐️ Fine-tuned our github pipelines and CDN (CloudFront) to enable us to deploy our CRM front-end without any downtime for the end user, which helped us to increase our deploy frequency from weekly to daily deployments.Designed and developed microservices hosted on a Cloud based infrastructure… Show more ⭐️ I’ve been able to reduce our AWS billing by 50%, through proper scaling of existing services and the deployment of auto scaling actions in our ElasticBeanstalk and Amazon RDS services. ⭐️ Fine-tuned our github pipelines and CDN (CloudFront) to enable us to deploy our CRM front-end without any downtime for the end user, which helped us to increase our deploy frequency from weekly to daily deployments.Designed and developed microservices hosted on a Cloud based infrastructure (AWS). Worked in the design and implementation of a custom feature packed CRM, working both at the front-end with Angular and at the back-end with NestJS. Maintained and evolved our Cloud based infrastructure, described with the help of Terraform. Show less

⭐️ I set up an EventBridge notifier which helped us to track Amazon spot termination, which was harming the uptime of core microservices (e.g: alarm microservices, notification queues). Having understood the issue, I worked in the refactor of such microservices, to increase their fault-tolerance and horizontal scalability. As a result of these efforts, our system was able to achieve +99.99% of uptime.⭐️ Enhanced ElasticSearch dictionary mappings’, which enabled us to better track which… Show more ⭐️ I set up an EventBridge notifier which helped us to track Amazon spot termination, which was harming the uptime of core microservices (e.g: alarm microservices, notification queues).

With this knowledge, we were able to refactor these APIs without disrupting other end-users services.Maintained and developed endpoints of a geo tracking platform using ASP.NET Core. Developed responsive web and mobile interfaces with React and React Native. Maintained deploy pipelines using Jenkins and Octopus. Helped to raise observability of our cloud systems through the development of Slack bots and configuration of Amazon Eventbridge platform. Show less
