I am a Infrastructure (DevOps) and Software Engineer with a deep obsession for building systems with high-availability, low-latency and observability capabilities.

Having built and operated my own tech project end-to-end from scratch, I bring a strong founder mindset—I take total ownership, solve complex system bugs independently, and deliver reliable infrastructure quickly. 

Core Expertise:

• Languages & Core: Python (Expert), Rust: Async / Tokio (Very Good), C, Bash, Systems Programming, Networking, Computer Science Fundamentals.
• Orchestration & IaC: Kubernetes (RKE2), Helm, OpenTofu / Terraform, Ansible, GitOps (Rancher Fleet). 
• Networking & Systems: Rust (Tokio), custom TCP protocols, Nebula mesh VPNs, Linux internals. 
• Observability Stack: OpenTelemetry (OTel), VictoriaMetrics, Grafana, OpenObserve, Tempo. 
• Databases & Queues: MongoDB, Redis, RabbitMQ, CloudNativePG (PostgreSQL), custom storage written in Rust using atomic system calls.
• Automation & AI: Extensive integration of LLM tools (Cursor, Claude) for fast IaC generation, automated log analysis, and incident triage. 
  
  

OPEN SOURCE CONTRIBUTIONS

Contributor | Grafana OpenObserve Datasource Plugin (written in Go) (https://github.com/LinPr/grafana-openobserve-datasource)

• Authored core query engine fixes handling dashboard fallbacks to align behavior between Grafana Explore view and dashboard panels.
• Implemented SQL LIMIT clause parsing to dynamically control search query payload sizes and prevent dashboard timeouts.

KEY PROJECTS & REPOSITORIES

• Modern K8s Observability Stack (https://github.com/bmsj5/modern-k8s-observability)
  • Turnkey observability solution for 3-node HA Kubernetes cells using OTel Collectors, VictoriaMetrics, OpenObserve, Tempo, and custom Grafana dashboards.
• Rancher Cluster Automation Templates (https://github.com/bmsj5/infra-template-rancher-management)
  • Reusable OpenTofu/Terraform and Ansible automation templates for provisioning production-ready HA RKE2 clusters with Cloudflare DNS integration and Rancher management wrappers.

ABOUT ME & ADDITIONAL PROJECTS

• Competitive ML & Data Science: (https://www.kaggle.com/aksanadarashuk/competitions) Modeled medical image processing pipelines using deep learning (PyTorch).

I am seeking remote B2B contractor roles (DevOps / SRE / Python / Rust / Systems Engineering or other similar language or tech stack if provided time to learn) or positions offering relocation. Available to start immediately.
