Tätigkeitsbeschreibung

As a key contributor to the infrastructure team, I undertook the revamping of
several critical components. Foremost among these was the MySQL database,
which underwent enhancements to boost stability, availability, and performance
significantly. Additionally, the implementation of a new Kubernetes cluster solution
effectively mitigated technical debt while enhancing scalability, thus providing a
potent tool for managing infrastructure costs. These transformative improvements
were seamlessly implemented using Infrastructure as Code, ensuring
comprehensive coverage across the infrastructure. Moreover, the integration of MongoDB and RabbitMQ further enriched the system's capabilities, enhancing data
storage and messaging functionalities.

My responsibilities encompassed the preparation of new infrastructure for
migration and orchestrating migration processes. The new infrastructure,
described as Infrastructure as Code (IAC), was implemented using Ansible and
Terraform, while leveraging VMware for virtualization. Migration processes involved
setting up pipelines to GitLab, configuring network switches, and integrating
RabbitMQ for messaging.

Tätigkeitsbeschreibung

I have rebuilt and migrated complex legacy multi-account AWS
cloud infrastructure with a set of different development
patterns to single and reliable infrastructure on top of AWS
cloud. We have described all infrastructure resources in
Terraform, Helm, and Docker declarative Infrastructure as a
code. Together with Infrastructure, we rebuild development
workflow to get fully autonomic continuous integration and
continuous deployment process. We have to implement GitOps
with ArgoCD and Gitlab-CI for infrastructure and application
automatic delivery. I have a delivery large impact on hardening
corporate security, data flow, and data processing. This
improvement
decreases
the
complexity
of
existing
infrastructure and as a result cost of ownership. In parallel, I
have work with the Corporate DataLake project that have got
concrete specification and development sprint. Kafka, AWS
Glue, MongoDB, and Snowflake will be the main components for
this ambition Data lake project.

Tätigkeitsbeschreibung

I have realized a deep transformation project. Application was
migrated from bare-metal monolithic application (PHP
Symfony,nodeJS,MongoDB) and primitive developer workflows,
to multi-cloud micro services infrastructure with fully automatic
infrastructure provisioning, builds, testing and deployments
from change request to production. For getting these results I
have built Infrastructure as a Code, fully autometed CI/CD
pipelines, trained DevOps Team in an Agile workflow, build
networks, secured policies and access rules and developed
several micro service applications.
I have used GitLab CI, Terraform, Kubernetes, Ansible, Python
and Golang. Data have operated by MongoDB cluster that build
on promise and Atlas MongoDB as SaaS that defined in
terraform state. Event processing realized with Cadence from
Uber and Apache Cassandra cluster as a data back-end.
Process and data workflow realized with Airflow and Tableau as
a visualization and data representation services. All systems
logs have collected and processed at EFK stacks.
