I contributed to the transformation of the infrastructure team, enabling them to handle all infrastructure tasks and execute infrastructure migrations effectively. Moreover, I revamped essential infrastructure components such as Terraform modules and Helm charts to address critical issues. Additionally, I designed and implemented infrastructure support plans, incorporating maintenance events and change scheduling. Furthermore, I collaborated with the team to integrate Kafka messaging for event-driven architecture with Java ,PHP (Symfony) and Node.js
applications.

8/2021 – 6/2022

The main activity of the project was related to refactoring infrastructure as a code for a set of applications. Key features were implemented in project gitops deployment with ArgoCD as the main orchestration tool. Projects include multi-cluster and multi-data-center and multi-regional decentralization concepts that realize high availability, high readability, and observability.

11/2020 – 7/2021

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.

6/2017 – 9/2020

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.

2/2017 – 6/2017

Main challenge was development and building infrastructure for
3D CAD rendering API application. In parallel, I have realized
several projects in data processing and developer process
workflows for several business departments of our customers. I
have realized business process management workflow with
JIRA, and Confluent collaboration with integration to several
corporate directory services Python, PostgreSQL, nomad, XEN,
docker, consul, MS AD, OpenLDAP, Single Sign-On and 2FA from
DUO.

10/2016 – 1/2017

I have created infrastructure and CI-CD pipeline for Edu-tech application on AWS, based on Kubernetes, Bamboo and other Atlasian tools for implementing best practices and Agile methodologies into development and business processes. Infrastructure and workflow setup for data flow analysis based at R-studio and PostgreSQL software stack.

10/2014 – 10/2016

I have created proof of concept for live and on-demand streaming service. I defined Infrastructure as a code for application and build and deployment of streaming services. I have built also built media transformation application, that converts video files to acceptable streaming format. I have developed DRM content protection system and integrated this DRM system to all components of the application.
