David Lednik

As a highly skilled cloud solutions architect, I was responsible for consulting and installing a Kubernetes cluster on Microsoft Azure. My role involved working closely with the client to understand their specific needs and requirements, as well as providing technical guidance and expertise throughout the installation process.

I successfully took over ownership of a PDF web viewer application that utilized React for the frontend and .NET Core for the backend. Over the course of five years, I led its development by implementing new features and improving existing ones, while also successfully refactoring the application to a completely new PDF library. Throughout my tenure on this project, I demonstrated expertise in React and .NET Core development, as well as ability to manage complex projects and push for innovation and quality improvements.

I set up quality assurance (QA) for a web-based application from scratch. This included setting up test servers and combining them with Azure pipelines to ensure that testing was streamlined and efficient. My work resulted in an HTML report that C-level executives could use to demonstrate that we had testing in place that catches any regressions before they impact customers.

Successfully delivered a proof of concept that demonstrated our ability to containerize and deploy all web applications, including backend servers/services, as Docker containers. This proved to C-level staff that we are capable of deploying everything on-premises when customers do not want to use cloud-based access.

Set up a new QA system for running E2E tests for a React based web application. The system took image snapshots and compared them to expected images to catch any rendering issues with the application as any missing information that is not rendered could lead to serious legal issues with clients.

Provided GIS Consulting services to a company using an old AutoCAD plugin that needed fixes and upgrades.
