Senior .NET Backend / Full-Stack Engineer · Muscat, Oman

I've been building software since 2003. Most of my recent work is backend and platform engineering with C# and .NET: distributed services, messaging, real-time data, caching, identity, database-heavy systems, and reusable libraries.

I still work with Angular when a feature crosses the UI, but backend architecture and systems work are where I spend most of my time.

• C#, .NET 8/9/10, ASP.NET Core, ABP
• Clean Architecture, DDD, CQRS/MediatR, modular monoliths and microservices
• Kafka, RabbitMQ, Redis, SignalR, WebTransport, gRPC and WebSocket
• PostgreSQL, SQL Server, MongoDB, MySQL and SQLite
• OpenTelemetry, xUnit, BenchmarkDotNet, Docker, Kubernetes and CI/CD
• OAuth2/OIDC/JWT, OpenIddict and policy-based authorization

A multi-repository .NET 8/9/10 streaming project I've been building around channels, protocol contracts, data-source adapters, cluster messaging, recovery and client libraries.

The public repositories are split by responsibility rather than putting everything in one package:

• ThunderPropagator.BuildingBlocks - shared abstractions and infrastructure
• ThunderPropagator.Channels - chat, monitoring, notifications, demos and multiplayer/game channels
• ThunderPropagator.Feeviders - adapters for Kafka, RabbitMQ, NATS, MQTT, Pulsar, ActiveMQ, Redis, cloud messaging, gRPC, WebSocket, TCP/UDP and other transports
• ThunderPropagator.ClusterMessageBuses - pluggable inter-node message buses and fan-out implementations
• ThunderPropagator.RecoveryHandlers - snapshot recovery with Redis, MongoDB and PostgreSQL
• ThunderPropagator.Clients - client protocol and wire-format specification
• ThunderPropagator.Clients.DotNet - .NET client implementation

Recent Channels work includes server-authoritative session state, reconnect handling, scoring and request authorization for a real-time quiz channel, with concurrency and serialization tests around the state transitions.

IIIF.Manifest.Serializer.Net is a version-aware .NET serializer for IIIF Presentation API 2.0, 2.1 and 3.0.

The current codebase includes:

• IIIF Presentation, Image, Auth, Content Search, Change Discovery and Content State models
• W3C-style annotations and version conversion
• navPlace, Georeference and Text Granularity extension packages
• System.Text.Json interoperability
• 557 unit tests plus 8 architecture tests
• roughly 82% line coverage for the core and extension packages

I've also been using the SDK to explore different persistence and change-tracking approaches:

• IIIF.POC.ChangeTrackingLab - object-graph changes and partial change sets
• IIIF.POC.PostgreSqlRelationalV3Store - EF Core/PostgreSQL relational mapping with JSONB for extension data
• IIIF.POC.EventSourcedManifestStore - append-only event streams with KurrentDB
• IIIF.POC.VersionLab - Presentation 2.x/3.0 detection and conversion

I'm also working on a private .NET 10 modular business platform under MinooTradingSPC. It covers areas such as accounting, billing, IAM, audit, customer/product/order management, notifications, search and scheduling, with shared CQRS, security, rate-limiting, export and workflow components.

The persistence layer is deliberately provider-oriented, with support across SQL Server, PostgreSQL, MySQL and SQLite where the module allows it.

• BlockChainLogging - append-only/tamper-evident logging experiment
• CaptchaWithSkiaSharp - CAPTCHA image generation with SkiaSharp
• PasswordGeneratorCLI - password generation library and CLI
• ZooKeeperDITester - distributed locking/DI experiment with ZooKeeper
• awesome-iiif - IIIF resources and references
