Overview
Senior .NET Engineer | TireCheck | Feb 2021 – Present | Ennis, Ireland (hybrid)
Working on a global IoT SaaS platform for tyre pressure monitoring and fleet
intelligence, serving 25K+ active B2B users across 48 countries.
Key responsibilities and contributions:
- Migrated legacy .NET Framework monolith to hybrid Azure cloud architecture
(Functions, Event Hubs, Service Bus), introducing message-driven design to
decouple ingestion, processing, and reporting layers for independent scaling.
- Developed a background scheduler service automating recurring tasks and
subsequently migrated core functionality to Azure Functions.
- Built resilient data ingestion pipelines for real-time IoT sensor telemetry,
handling high-volume concurrent streams with validation and retry logic.
- Optimised heavyweight reports through query rewriting, indexing, and
read replica databases — eliminating production performance bottlenecks.
- Designed and delivered a REST API layer enabling third-party integrations.
- Implemented multi-tenant RBAC and client onboarding workflows for enterprise
fleet operators across 48+ countries.
- Refactored and consolidated domain models into a shared core layer.
Tech stack: C#, .NET Core, ASP.NET Core, Azure Functions, Event Hubs,
Service Bus, MSSQL, Redis, Entity Framework, Git
