Projekthistorie
- The overall goal of the project is reliable, automated content distribution for Outdoor Advertising.
- I worked in a DevOps team which aims to speed up delivery of software features to production using principles of CI/CD, Infrastructure as Code (IaC) and extensive use of Terraform and Kubernetes.
- I was responsible for maintenance of existing infrastructure managed with Chef and AWS OpsWorks, debugging operational issues and tracking down performance bottlenecks.
- I designed a serverless AWS infrastructure for a monitoring solution supporting thousands displays installed in trains.
- I created a framework that allows developers to quickly and independently integrate their new services into existing infrastructure.
- I made multiple Proof of Concept solutions based on AWS to help the client choose the optimal technical stack for their new projects.
- * Worked proactively with high-growth startups and operated as their trusted technical advisor in the development of cost-efficient cloud architectures tailored to their business priorities.
* Designed and implemented highly available cloud-based infrastructure for software development, data analysis and production for customers in a variety of industries.
* Proposed and implemented cost optimization plans.
* Improved production systems to efficiently carry out TV advertisement load profiles.
* Planned and executed infrastructure migration to AWS.
* Supported B2B deals in fintech with product documentation, security audits, and technical consultancy.
* Led proof-of-concept prototyping in eCommerce, IoT, and AI projects.
* Supported software development teams with CI/CD automation and cloud services expertise.
* Defined the requirements for software delivery processes and created a framework for rapid integration of new services into Kubernetes infrastructure.
* Refactored web services backed by EC2 servers into serverless solutions, eliminating 90% of the AWS bill.
Automatic replenishment trigger system for car manufacturing plants.
I refactored the AWS infrastructure automation, improving distribution of the serverless applications, security and billing. The refactoring enabled better integration with the Industrial Cloud project.
I designed a serverless solution with cost-efficient multitenancy support
I refactored key services into serverless applications and set up an infrastructure framework and processes, which made services development independent and compliant with strict security requirements.
I organized the development workflow, set up CI/CD pipelines, local and remote environments for developers.
I built a serverless backend and AWS infrastructure which helped the team to deliver the MVP in just a few weeks.
I have been supporting the company for 4 years with my AWS expertise and development skills, being the main contact person for CTO, COO, both frontend and backend development teams, in questions around infrastructure and development workflows.
My main responsibility was to fully automate the infrastructure deployment for each business client in dedicated AWS accounts with staging and production environments, meet country-specific regulations and internal IT policies.
I created an automation framework with full coverage of AWS resources in Infrastructure-as-Code (IaC), which allowed Spotcap to onboard new clients about 4 times faster.
I analyzed the Kubernetes-based infrastructure and helped the DevOps team to resolve reliability and performance issues.
I set up a Jenkins Pipeline and refactored a few web services backed by EC2 servers into serverless solutions, eliminating 90% of the AWS bill.
I set up CI/CD pipelines for the BI department.
I migrated the ETL infrastructure from Docker Swarm to AWS ECS with full coverage of Infrastructure as Code (IaC).
The migration significantly improved reliability and performance of the pipeline.
I created CI/CD pipelines for the testing and deployment of complex containerized applications.
I designed and tested AWS infrastructure for a data lake and data analysis based on Kubernetes.
The solution helped to onboard customers in both cloud and on-premise environments.
I created frameworks for software delivery and deployment in AWS with infrastructure as Code (IaC).
I was entirely responsible for the infrastructure of B2B services and provided all CI/CD, staging and production environments on time.
An international charging platform for electric vehicles: a joint venture of BMW Group, Bosch, Daimler AG, EnBW, innogy and Siemens. The service provides roaming APIs for charging stations to let end users charge their vehicles on any station without a direct contract with the provider.
My main objective was to migrate an existing on-premise solution to the new Java Spring microservices in AWS in 4 months, with a team of 3 devops engineers.
I led development of infrastructure-as-code including monitoring, disaster recovery, auto scaling, security enhancements.
I designed the missing parts of the infrastructure and improved it for production workloads and real world use cases.
I automated AWS environments with Infrastructure-as-Code (IaC) using AWS CloudFormation.
I set up CI/CD with Jenkins Pipelines and necessary environments and proactively supported developers.
The service has been successfully launched on time.
I identified performance bottlenecks and improved the AWS infrastructure to efficiently scale-out for the massive traffic growth.
I refactored a manually configured AWS deployment of a document management system based on plain EC2 servers into a containerized solution managed by ECS.
The reusable Infrastructure-as-Code allowed the client to estimate and plan migration of other services.
I supported the DevOps team with the knowledge of AWS best practices to eliminate unintended AWS costs, significantly speed up the development routines.
I on-boarded and launched an externally developed web service that helps people connect with hearing experts online.
I implemented CI pipelines for development teams and set up reusable AWS infrastructure to support multiple games using AWS OpsWorks.
The solution allowed to launch the game on time and was used to onboard the next games faster.
I created a CI/CD pipeline for development and production deployments in AWS infrastructure and integrated frameworks for automated end-to-end testing.
The solution was adopted by other eCommerce companies in the VC to speed time to market.
