Most experience is derived from writing server-side logic and front-end components for products like ADONIS or ADOIT and their customization plugins. One of such plugins is a BPMN Process Simulation and BPMN Process Stepper. Also, were using modern Js/Ts + React tech stack for creating organizationally-platform level test results dashboard for build pipelines tests results, integrated into multiple teams pipelines. This CV is also created using such tech stack as well. Also a bit experienced with TypeScript, but considering it as a preferred way to write Js-based code.

Experienced in writing organizationally-wide libraries and scripting ecosystem, which are reused in build pipelines and local custom development tooling. Experiences in migration old->to->new Python codebases. Having experience of writing Temporal workers in Python. Also, used Python as a core language for creation data testing framework for Elasticsearch and KPIs data proceeding derived from multiple data sources. More about my way of thinking of data proceeding you can read in my Data Mesh article.

Built knowledge on GoLang technology during creation deployment and data proceeding workflows in Temporal technology in microservices-based system.

Having basic knowledge which allows me doing simple administrative things when working on remote VMs or during containers debugging. Also, used bash scripts for 1-click ELK stack local dev installation.

Experience of writing queries for MsSQL database import, export and backups which are part of an automated ecosystem.

Writing Jenkinsfiles and custom Gradle tasks logic.

Creating algorithms, including working with graphs. One of prominent projects where I implemented those knowledges are BPMN Process Simulation and BPMN Process Stepper.

Creating html pages. One of examples is my personal photo portofilo and current CV (which is Next.js - based).

  - Log data analysis collected from distributed Jenkins instances
     to derive measurements over builds statuses/anomalies and overall quality.
  - Crafting dashboards.
  - Made set up for multiple teams, each with private space.
  - Creating miscellaneous Logstash pipelines and patterns.
  - Created custom testing framework for testing Logstash pipelines by using simulated raw data.
  - Experienced in Fluentbit + ELK.
  - Experienced in Kafka + ELK.
  - Experienced in OTEL + ELK.
  - Experienced in cluster set up.
  - Experienced in Elastic Agents set up.
  - Experienced in APM for Microservices to collect and correlate logs, metrics and traces.
  - Fine-tuning Filebeat for optimal logs ingestion.
  - Able to use scripting for convenient local set up for rapid pipelines development for teams.

Experienced with Fluentbit to collect containers logs for ELK integration.

Enabled SonarQube + SonarLint in BOC Group organization for build/test pipelines executed in different VM environments with all necessary docu/guides for all BOC developers.

Containerizing microservices and 3rd-party services. Able to debug, secure, troubleshoot and optimize images for efficient resources usage.

Modelling and creation CI/CD pipelines. Experienced in creation and maintaining pipelines-as-a-product for organizational-wide reusing with integration into the modules, plugins, libraries and services ecosystem.

Experienced with JFrog Artifactory for artifacts management, setting up users/groups and it's API usage.

Experienced with Rhodecode source code platform.

Experienced with version control using Git, managing branches, and collaborating on code. Integrated git hooks and reusable git scripts into platform layer Gradle plugins and miscellaneous libraries.

Experienced with Mercurial for version control, similar to Git. Integrated reusable hg scripts into platform layer Gradle plugins and miscellaneous libraries.

Integrated Apache Kafka into ELK stack for Beats->to->Logstash data streaming. Having understanding of event-driven architecture and basic Kafka capabilities. A bit of experience with basic Kafka cmd tools.

Experience with Redis in Node.js-based microservice.

Experience with using terminal toolings for remote server access and management.

Experienced with AWS infrastructure set up. My Terraform GitHub repo.

Experience with using Hashicorp Nomad for managing End-To-End products deployments like ADONIS, ADOIT or ADOGRC.
