Background

About Dimitris Papageorgiou

I am a Senior Software Engineer and developing Software Architect with a solid full-stack and cloud background, working primarily with Java and C# on the backend and Angular and React on the frontend.My career spans software engineering, cloud solution design, DevOps practices, and infrastructure implementation, giving me a comprehensive understanding of how modern systems are planned, built, deployed, and operated.A significant part of my experience has been in the eGovernment sector, where I have participated in and led projects that require strict standards for security, reliability, and compliance. I have worked both as a senior engineer and as a team lead, contributing to architectural decisions, supporting team members, and ensuring smooth delivery from initial design through to production. My technical background includes building scalable backend systems using Spring Boot, reactive programming, and.NET Core/MVC, with an emphasis on clean architecture, modular design, and long-term maintainability. On the frontend, I have delivered solutions using Angular and React, giving me full-stack capability when required. Throughout the development lifecycle, I apply best practices for unit testing, integration testing, CI/CD, and environment management to ensure quality and consistency.In recent years, my work has focused heavily on designing and implementing cloud solutions on the Azure Cloud Platform. I have experience taking systems from conceptual architecture through deployment, using Azure DevOps pipelines for automated builds, releases, policy enforcement, branching strategies, and test integration. I work with Infrastructure as Code using Bicep, designing and configuring environments that include virtual networks, subnets, private endpoints, NSGs, firewalls, and secure communication flows.I have built solutions using a broad set of Azure services, including App Services, Azure Functions, Service Bus, Event Hubs, Application Gateway, API Management, Key Vault, Azure Storage, and Azure AI Search, as well as supporting services such as Azure Translation, Entra ID, and managed identity based authentication. My work consistently involves secure by design patterns, proper identity management, and adherence to cloud governance.Beyond cloud and application development, I have hands-on experience with Docker, containerized deployments, container registries, and server configuration and maintenance. I also work on performance optimization, scaling strategies, logging, monitoring, and overall application stability within distributed environments.
