Ahsan Malik.
Lead Software Engineer - Rust - .NET 10 - AWS/Azure - AI Orchestration
Senior engineer with around 8 years of experience building backend services and full-stack applications. Deep expertise in .NET (ASP.NET Core, C#) and in more recent roles Rust (Axum) and AI agent orchestration (Microsoft Agentic Framework). Comfortable across the stack — from API design and modern databases to UIs in React, Angular, or Dioxus. Worked across FinTech, E-Commerce, and Healthcare, mostly in small to mid-sized teams where engineers own features from design through to production.
- Building multi-agent orchestration for underwriting decisions and claims analysis using .NET 10 and SurrealDB
- Developed autonomous agents evaluating policy applications against risk guidelines
- Wrote custom Function Tools enabling real-time risk assessment via live internal API data
- Set up Azure Entra ID SSO across all .NET services for policyholder data security
- Rewrote core order-routing from ASP.NET Core to Rust (Axum + Tokio) across 12+ markets; significant response time improvement
- Used strongly-typed Serde contracts across service boundaries, catching serialisation issues early
- Replaced Redis caching with lighter in-process Rust shared state — reduced memory footprint
- Built internal admin tool with Dioxus, sharing domain types with the Axum backend
- Migrated deployments to Terraform + GitHub Actions for repeatable multi-market environments
- Wrote post-Kicks acquisition inventory sync layer in Rust (Axum + Tokio) — previous .NET prototype couldn't handle event volume
- Warehouse routing with sqlx + PostGIS queries — faster and more accurate than prior ASP.NET Core + LINQ approach
- Async event pipeline using Tokio channels and Azure Service Bus
- Live fulfilment dashboard in Dioxus (WASM) with SSE from Axum backend — replaced static Razor Pages report
- Added OpenTelemetry tracing across Rust services using the tracing crate
- ASP.NET Core backend with CQRS + MediatR + Vertical Slice Architecture, EF Core data access
- Pricing engine integrating DTOne & Reloadly APIs; Polly retry + circuit-breaker for resilience
- React/TypeScript customer dashboard with React Query; Angular + NgRx back-office modules
- Azure API Management + Key Vault for API key security
- Decomposed .NET monolith into campaign and billing ASP.NET Core microservices
- React campaign dashboard with Voucherify integration and SignalR live metrics feed
- Migrated legacy remittance monolith to ASP.NET Core with Clean Architecture + CQRS
- Refactored React frontend to functional hooks; live exchange rate views significantly more responsive
- Implemented ASP.NET Core Identity + JWT for KYC/financial compliance
- EF Core financial reporting + Excel export; xUnit integration tests in GitHub Actions CI
- Patient management, appointment scheduling, and EHR modules in ASP.NET Core + EF Core
- Angular dashboards with NgRx state and Angular Material; RBAC via ASP.NET Core Identity + Angular route guards
- Tracked down and fixed N+1 query issues and missing indexes — report generation significantly faster
