Professional Summary

Principal Software Architect and Solution Architect with 25+ years of experience in C#/.NET and Microsoft Azure. I design end-to-end solutions, stay hands-on in the code, and grow the engineers who maintain the systems. My specialism is pragmatic cloud modernisation: migrating legacy monoliths to cloud-native, distributed microservices on Azure through evolutionary architecture rather than big-bang rewrites. I own architecture end to end, from technical strategy, roadmap and governance through to production performance. At Xtel I cut backend response times from more than 20 seconds to under 3 seconds.

My engineering practice is grounded in Test-Driven Development (TDD), Clean Architecture, and Domain-Driven Design (DDD). I have mentored 20+ developers, many of whom have since moved into senior or lead roles. I use AI-assisted development (Claude Code, Cursor) every day. I am also building AI integration capability (Semantic Kernel, Azure AI Foundry) as a first-class architectural concern.

Professional Experience

Software Architect | Xtel | Jan 2025 – Present

Global revenue management solutions provider for FMCG companies. Leading enterprise cloud transformation.

  • Improved backend response times from more than 20 seconds to under 3 seconds through query optimisation, serialisation, and caching strategies.
  • Architect the incremental migration (Strangler Fig approach) from monolithic legacy systems to Azure-native distributed microservices. Own the technical strategy, roadmap and architecture governance for a platform serving global FMCG clients.
  • Lead and mentor a team of 8 engineers in Clean Architecture, TDD, and cloud-native development. Reduced code review cycle time by 35%.

Technologies: C#, .NET Core, Azure Functions, Azure Service Bus, Azure Cosmos DB, Azure Kubernetes Service (AKS), SQL Server, Microservices

Software Architect | Adesso IT | Jun 2023 – Dec 2024

Global IT consultancy. Provided strategic technical leadership and legacy modernisation for client engagements.

  • Assessed the architecture of legacy codebases across multiple client engagements. Identified technical debt and delivered pragmatic modernisation roadmaps that balanced business continuity with long-term maintainability.
  • Established Test-Driven Development across client teams. Raised test coverage from 15% to 75% within two delivery cycles.
  • Mentored 12+ developers in testing methodologies, clean code, and architectural thinking. Several have since progressed to lead roles.

Technologies: C#, .NET Core, ASP.NET Core, Microsoft Azure, TDD, BDD, Refactoring

Team Lead | EPAM Systems | Sep 2021 – Jun 2023

Global IT consultancy. Led multiple teams in the logistics domain.

  • Led two Agile teams (14 engineers) delivering a logistics platform that processes 50,000+ parcel transactions per day at 99.9% uptime.
  • Architected a distributed, event-driven solution spanning a .NET MAUI mobile app, .NET Core APIs, and a Blazor web portal for real-time parcel tracking across the full delivery lifecycle. Applied CQRS in parts of the portal.
  • Designed the Azure infrastructure with Azure Cosmos DB, SQL Server, Azure Service Bus, and Azure Functions, chosen to fit the event-driven model and operational scale.
  • Cut deployment time from 4 hours to 30 minutes by introducing CI/CD automation. Three more teams in the programme later adopted it as their standard.
