What I do

My areas of expertise are detailed

My expertise encompasses software development, DevOps, cloud computing, and Big Data solutions, leveraging a diverse skill set in Java, .NET, Kubernetes, and modern infrastructure management tools.

Kubernetes & GitOps

My expertise extends to managing clusters using Rancher and RKE for on-premise and cloud solutions on AWS, Azure, and Linode. I am adept at writing custom operators, automating processes with Argo-Events, and crafting and maintaining advanced Helm charts.

Infrastructure as Code

I write Terraform and Ansible, including custom modules, to keep infrastructure consistent and reproducible across every environment I touch.

Cloud Platforms

In cloud management, my expertise spans across AWS, Azure, DigitalOcean, and Linode (Akamai), with a strong emphasis on FinOps and optimizing for cost efficiency and performance.

Data Platforms

My proficiency spans Oracle, MySQL, MS SQL Server, MongoDB, Cassandra and Elasticsearch, employing Spark for big data processing and orchestrating pipelines with Kubernetes-native tools like Argo Workflows and Luigi.

Full-Stack Development

As a seasoned developer across front-end and back-end technologies, I work from .NET, Java, Scala, Go and Python to modern front-end frameworks, and pick up code written by others quickly.

Scripting & Automation

I lean on Python and Bash scripting to strip manual steps out of both development and infrastructure workflows.

My story

Biography

1999 — Getting started

I began my career as a software developer in 1999. My first role involved developing a web system in Java with minimal JavaScript use. During the 2000–2001 crisis I was laid off, but within two weeks returned to work — this time using classic ASP and VB6 on an IIS server, right as the idea of the Single Page Application was emerging.

2004 — The .NET decade

In 2004, I transitioned to learning C# and the ASP.NET framework for web system development, using ASP.NET AJAX for client-server communication and SQL Server for data storage. Over the next ten years I worked extensively as a full-stack and backend .NET developer, writing Windows services, SSIS applications and PowerShell scriptlets, and building jQuery clients and plugins.

2014 — Big Data & architecture

In 2014, I shifted focus to become a solution architect on a Big Data team, working with Hadoop, various NoSQL databases and Elasticsearch. I revisited Java, learned Python, and began using Node.js and Angular.js for rapid service development — while gradually making Linux my primary OS.

2017 — Into Kubernetes

In 2017, I returned to a developer role as a Senior Software Developer and began working with Docker, migrating systems from Docker Swarm to Kubernetes. I built CI/CD pipelines with Jenkins and Groovy and automated installs with Python and Ansible — which led me into a DevOps role in 2019.
