Open to OpportunitiesAbout Me
Experienced DevOps and Infrastructure Engineer, taking end-to-end ownership of production environments, from bare-metal and edge devices to highly available Kubernetes clusters.
Specialized in Kubernetes architecture, Helm chart design, and CI/CD pipelines (Jenkins, GitHub Actions, Bitbucket Pipelines) with GitOps automation (FluxCD, ArgoCD). Hands-on with Ansible for zero-touch provisioning and k3s for air-gapped edge deployments, including full monolith-to-Kubernetes migrations for production environments.
Designing multi-region AWS platforms (CloudFormation, SAM) with VPN-first architectures (WireGuard) linking edge deployments to cloud-hosted services. Layered IaC with Terraform, Terragrunt, and CloudFormation for modular, reusable infrastructure.
Building agentic AI systems and organizational knowledge infrastructure, including an Organizational Brain reasoning layer, an AI-awareness layer, and multi-session Claude architectures. Working with LangChain, embedding models, and Qdrant to power retrieval and memory for these pipelines.
What drives me is ownership — seeing a system through from design to production, and being the person a team can rely on when something breaks. I pick up new tools and domains fast, thrive on ambiguity, and believe the best infrastructure gets built by teams that trust each other, not by any one person working alone.

Projects
Selected work across infrastructure, automation, and systems engineering
This Website
The portfolio website you are currently viewing, built with Python (Flask), HTML, CSS, and JavaScript, based on Terraform IaC, AWS, K8S and ArgoCD, to showcase my work and skills.
Mission Recorder Subsystem
An event-triggered data collection subsystem designed for air-gapped edge devices. It automates the gathering and packaging of logs and system data using Python, Docker, and Fluent-bit to ensure observability in isolated environments.
Kafka Data Shipping
Kafka data shipping microservices architecture, using Java producer-consumer services to stream data between MySQL and Kafka. Deployed on AWS EKS using Terraform IaC, CI/CD process was automated with GitHub Actions to build and push container images to ECR.
Portfolio Blog
A full-stack microservices blog application demonstrating content management and web development skills, and Monolith to Microservices migration.
Terragrunt Infrastructure
Advanced IaC by DRYing up Terraform code, managing remote state, and orchestrating multi-environment deployments for VPCs and EKS clusters.
Golang Booking Application
CLI-based application built while mastering Go — focuses on core concepts such as concurrency (Goroutines), pointers, and structured data to handle real-time booking logic.
Chatapp
A real-time chat application built to implement WebSocket technology for instant two-way communication, on a simple microservices architecture.
Blue-Green Deployment
Blue-Green deployment using Terraform and AWS. Nginx redirects traffic to the green server with the blue server as a backup.
Prometheus Data Collector
A custom exporter for the Prometheus monitoring system, built to gather and expose specific metrics for observability.
GateUP (Serverless)
A utility tool to manage and automate gate operations focusing on system integration and remote control, based on serverless event-based operations.
Ansible Automation
Rolling update deployment strategies using Ansible playbooks — updating server groups sequentially while maintaining service availability.
Linux Server Data Collection
A collection of Bash scripts and tools for gathering, processing, and analyzing performance and system data from Linux servers.
