ABP Framework Expert | Senior .NET Architect
Skilled in .NET, ABP Framework, Angular, and Blazor.
Proficient in microservices, modular monolith, and monolithic architectures.
Hello Upwork members,
I'm a Senior Full Stack Engineer specializing in ABP Framework and ASP.NET Core, with 3+ years building enterprise SaaS products, from founding engineer on a 17-service microservices platform to modular monolith ERPs, hotel and hospital management systems, and cross-platform apps running on a single Blazor codebase.
๐ป Core ABP & .NET Expertise
โ ABP Framework (modules, multi-tenancy, subscription system internals, OpenIddict)
โ Domain-Driven Design, aggregates, domain managers, domain events, Notification Pattern
โ CQRS + MediatR, Inbox/Outbox pattern, event-driven architecture with RabbitMQ
โ Entity Framework Core (migrations, query optimization, keyset pagination)
โ Custom SaaS subscription systems, dynamic plan builders, Stripe billing, tenant provisioning
๐ Full Stack & Frontend
โ Angular (reactive forms, RxJS, LeptonX theme customization)
โ Blazor Server, WebAssembly, and Hybrid โ plus .NET MAUI for shared web/desktop/mobile codebases
โ ASP.NET Core Web API, REST design, YARP API gateway
โ PostgreSQL, Redis distributed caching
๐๏ธ Architecture I Actually Ship
โ Microservices (schema-per-service PostgreSQL, RabbitMQ event bus, centralized OpenIddict auth)
โ Modular Monolith (my default recommendation for most SaaS, enforced module boundaries, DIP-based cross-module communication)
โ Clean Architecture and CQRS where the problem actually calls for it
โ SaaS multi-tenancy, timezone-aware scheduling, department-level data isolation
๐ Security & AI Integration
โ Led full remediation of a third-party pentest (4 critical + 6 high findings), HttpOnly cookie migration, CSP rollout, JWT claim hygiene, OAuth grant hardening
โ Built an MCP server on a live production ABP system for AI agent integration, and Semantic Kernel-powered live-data chat interfaces
๐ Why Clients Choose Me
โ Deep, multi-system ABP Framework experience, not a single-project generalist
โ Clear judgment on monolith vs. modular monolith vs. microservices, based on actual requirements, not trend-chasing
โ Security treated as architecture, not an afterthought
โ Founding-engineer experience, I can own architecture solo on a greenfield product
If you need someone who can architect an ABP-based SaaS platform end to end, backend, Angular/Blazor frontend, and the infrastructure decisions in between โ let's talk.
