Welcome to my GitHub profile! I started my career engineering steel hulls and shipyard automation systems β€” where a miscalculation could sink something worth millions. That instinct for precision, resilience, and systematic thinking is what I brought into cloud architecture. Today I design infrastructure that doesn't sink either: automated, observable, recoverable systems built for teams that need to move fast without breaking things. Every repo on this profile is a solved problem, a lesson documented, or a concept pushed until it clicked.

πŸ’Ό How I Got Here

Most DevOps engineers come from software development. I came from shipbuilding β€” and I think that's made me a different kind of engineer.

🚒 Shipbuilding Engineering Β Β·Β  2018–2021

Graduated with a Diploma in Shipbuilding Technology. Spent three years in an environment where precision isn't a preference β€” it's a structural requirement. My first real automation work happened on a shipyard floor, not a server rack: streamlining CAD/CAM workflows and documenting complex manufacturing systems for teams that couldn't afford ambiguity.

What I actually did...
β€’ Led technical documentation and multi-stage design review processes
β€’ Identified and automated repetitive engineering workflows
β€’ Collaborated with cross-functional teams across planning, production, and QA
β€’ Developed fluency in CAD/CAM tooling and production scheduling systems

πŸ’» Self-Taught Transition Β Β·Β  2021–2022

While still working in engineering, I taught myself Python and Shell scripting at nights and weekends. Built internal tools that cut documentation processing time by 40%. That number got attention β€” and it confirmed that automation could be my full-time work, not just a side project. I left engineering behind and didn't look back.

What I actually did...
β€’ Mastered Linux system administration and Bash scripting alongside a full-time role
β€’ Completed AWS fundamentals certifications to validate early cloud knowledge
β€’ Built workflow automation tools adopted by colleagues with no software background
β€’ Started contributing to open-source projects to learn from real production codebases

☁️ DevOps & Cloud Engineering Β Β·Β  2022–Present

Made the full transition into DevOps. Enrolled in the DevOps Career Track Season 2 by Poridhi for structured, hands-on depth alongside real project work. Previously drove enterprise-level cloud migration projects achieving 60% faster deployment cycles. Every project on this GitHub reflects real implementation β€” not tutorials, not templates, not copy-pasted YAML.

What I actually did...
β€’ Architected multi-cloud infrastructure across AWS, GCP, and Azure
β€’ Deployed production K3s and EKS clusters on AWS using Terraform IaC
β€’ Built Jenkins CI/CD pipelines with distributed agent configuration on AWS
β€’ Implemented K8s autoscaling, rolling updates, and StatefulSet management
β€’ Configured Docker-based monitoring stacks with automated alerting

πŸ“š Ongoing Education Β Β·Β  Now

Pursuing a Bachelor's in Computer Science (Cloud Computing) while preparing for the AWS Solutions Architect Associate exam. My learning style is hands-on first: I build the thing, break it, rebuild it better, then write about it. That's what the repos and blog posts are β€” documented evidence of the process.

What I'm actively doing...
β€’ Writing technical deep-dives on Kubernetes, Docker, and cloud architecture
β€’ Maintaining an automated LeetCode solutions system with analytics
β€’ Building GitOps lab environments with ArgoCD and Flux
β€’ Studying distributed systems and advanced AWS architecture patterns
β€’ Contributing to cloud-native open-source projects

πŸš€ Featured Projects

Enterprise-grade Kubernetes infrastructure on AWS EKS, designed for multi-environment production deployments. Implements a complete IaC stack covering cluster provisioning, node group management, IAM role binding, and network policies β€” built to be cost-effective without sacrificing scalability or reliability.

Production-ready K3s lightweight Kubernetes cluster on AWS, fully automated through Terraform. A complete infrastructure-as-code blueprint covering EC2 provisioning, VPC networking, and K3s cluster bootstrapping β€” demonstrating that lightweight doesn't mean cutting corners on production readiness.

Hands-on implementation of Kubernetes Horizontal Pod Autoscaler β€” the mechanism that separates truly elastic systems from ones that just claim to be. Builds a real workload, fires synthetic traffic at it, and watches the cluster respond: pods scale out under load, scale back when it clears. Includes metrics-server setup and threshold tuning.

Implementation of zero-downtime deployment strategies using Kubernetes rolling updates and rollbacks. Covers maxSurge/maxUnavailable tuning, readiness probe configuration, and rollback execution β€” the real ops work that keeps services alive through deployments. Includes failure simulation and controlled recovery.

Comprehensive Jenkins CI/CD implementation from bare infrastructure to a fully operational distributed build environment. Covers automated server provisioning on AWS, controller-agent architecture configuration, job management, and enterprise-grade automation practices β€” the full pipeline lifecycle, not just a hello-world pipeline.

A multi-container system where NGINX doesn't just run β€” it's watched. A dedicated watcher container continuously polls the server's health; on failure, a mailer container fires an automated alert instantly. A clean, composable implementation of the sidecar monitoring pattern that reflects how production observability actually works at the container level.
