Dimitrios T

Principal Product Engineer & Software Architect, based in Athens, Greece.

I take a product from idea to production in weeks, as both architect and builder, with 24 years of experience in enterprise software development and SaaS systems.

Since 2002, I have engineered software where architectural discipline meets real-world consequence. My background spans the full technical spectrum: from low-level operating system internals and high-throughput financial ETL pipelines to scalable cloud infrastructure, multi-tenant SaaS backends, and modern Generative AI orchestration. Across every tier, my focus is on building resilient, deterministic systems engineered for longevity, security, and operational reliability.

My engineering foundation was built in high-consequence environments, co-designing banking data warehousing engines processing hundreds of millions of records overnight with minimal errors. That standard of rigor carried directly into executive engineering leadership: architecting multi-tenant cloud platforms across AWS and Azure, automating complex integrations across CRM and ERP ecosystems, and deploying high-throughput .NET 9/10 and SQL backends paired with real-time Vertex AI streaming, dynamic prompt governance, and voice synthesis for novel media generation platforms.

Core Specializations

  • Architecture: Distributed Systems, Clean Architecture, Multitenancy, AWS Well-Architected Framework
  • Cloud & Backend: .NET 9/10, C#, ASP.NET Core, PostgreSQL, SQL Server, AWS, Azure, GCP, SignalR
  • Client & Native: React 19, Electron, TypeScript, WinUI 3, WPF, Swift 6, Kotlin
  • Security & AI: LLM Orchestration, Generative AI, DevSecOps, Autonomous Agent Workflows, Cryptography

Outside of distributed systems architecture, I write English literary science fiction novels and practice Krav Maga. I also enjoy cosmology and popular science.

I am available for remote B2B contracting, fractional systems architecture, and full-stack delivery with companies across North America (US & Canada), Europe, and worldwide. Reach out via LinkedIn or via email. Please feel free to ask me for a detailed career dossier for more details on my projects and let's connect.
