๐Ÿ‘จโ€๐Ÿ’ป Who I Am

๐ŸŒฑ I'm continuously improving and learning (both professionally and personally) Python, Java, and multiple other languages, including web development, infrastructure automation, and emerging technologies. Currently a Cloud Engineer at BCX working on enterprise cloud migration and automation initiatives.

I love debating and researching fringe subjectsโ€”you can find my research papers in my dedicated repository with ongoing theoretical work. There are also some interesting theoretical quantum physics projects, LLM exploration, and physical simulation systems I'm tinkering with in my spare time (fueled by whatever's playing above ๐Ÿ‘†).

๐Ÿ’ฌ Some of my core skills:

  • Scripting & Automation: Bash, Batch, Python, pwsh, Shell (5/5) - expert level
  • Web Development & APIs: HTML5, CSS, nginx, JavaScript, Express, Node.js, npm, REST APIs (5/5)
  • Operating Systems: UNIX, FreeBSD, Linux (CentOS, RHEL, Ubuntu, Debian), Windows Server
  • Mobile & Security: Android ROM flashing, OEM unlocking, custom bootloaders, rooting, Xposed Framework; Security and Encryption research
  • Databases: Oracle RDBMS, MySQL, PostgreSQL, MongoDB, SQL (3/5)
  • Cloud & Infrastructure: AWS (3/5, AWS Certified Cloud Practitioner), GCP (5/5), Vultr (3/5)
  • Containerization & Orchestration: Docker (5/5), Kubernetes (5/5), GKE, EKS, Rancher, Portainer
  • Infrastructure as Code: Terraform (4/5), Ansible/AWX (5/5), HashiCorp Vault (3/5)
  • CI/CD & DevOps: Jenkins, GitLab CI/CD (5/5), GitHub Actions (5/5), Maven (5/5), Git workflows (5/5)
  • Monitoring & Observability: Grafana, Kibana, Elasticsearch, RRDTool, Zabbix
  • Quality Assurance: Testing frameworks (JMeter, JUnit, TestRail), QbD, CQI
  • DevOps Excellence: Infrastructure automation, DevOps as Code, Dev environments as Code (Gitpods), CVE patching, security analysis, DR planning
  • On-Premise to Cloud: Hybrid & multi-cloud architecture, bare metal to cloud migrations
  • Anything that poses a good challenge or makes a good project!
  • Cryptography :3
