TARIK MADEN
PROFESSIONAL SUMMARY
Results-driven Backend Developer with 6+ years of experience engineering high-throughput distributed systems, fintech transaction pipelines, digital wallets, and modular enterprise ERP suites. Core expertise centered on .NET Core (C# / ASP.NET Core) and PHP (Laravel) ecosystems, supported by hands-on Java (Spring Boot) and Python experience across event-driven microservices, resilient REST APIs, and asynchronous background pipelines. Designed end-to-end processing engines for TROY and Mastercard card services, CBRT FAST instant transfer integrations, and automated financial clearing/reconciliation workflows in .NET Core. Slashed critical API latency by over 30% through advanced database indexing and query tuning with Entity Framework Core, Dapper, and Eloquent ORM. Dedicated to Clean Architecture, Domain-Driven Design (DDD), and SOLID principles to deliver highly reliable and scalable enterprise software solutions.
TECHNICAL CORE COMPETENCIES
PROFESSIONAL EXPERIENCE
- .NET Core TROY & Mastercard Card Services Architecture: Architected and engineered core processing pipelines across TROY and Mastercard card services using ASP.NET Core (.NET 8/9) and C#; managed 3D Secure authentication, pre-auth/auth, capture, and real-time routing for void and refund transactions.
- .NET Core Clearing, Reconciliation & End-of-Day (EOD) Automation: Built backend services with .NET Core automating the daily segregation of sales, voids, reversals, and refunds; implemented clearing file generation and general ledger reconciliation workflows with scheme partners.
- CBRT FAST Service Integration (.NET Core): Orchestrated the Central Bank FAST (Instant and Continuous Transfer) routing engine using ASP.NET Core; implemented ISO 20022 message transformation, sub-second dispatch, and 24/7 continuous settlement pipelines with automated failover routines.
- Asynchronous Messaging & Event-Driven Architecture (RabbitMQ & Redis): Constructed an event-driven messaging backbone with RabbitMQ and Redis to decouple wallet, payment, and notification flows; enforced deterministic idempotency guards and Saga compensation workflows via .NET BackgroundService and distributed workers.
- Deep Query Optimization & Enterprise Governance (EF Core & Dapper): Slashed critical API latencies by over 30% through advanced database indexing and query tuning across PostgreSQL and MySQL using EF Core and Dapper; managed OAuth2/JWT security, mTLS communication, and tamper-evident audit logs aligned with PCI-DSS.
- Laravel & .NET ERP Dashboards & Mobile REST APIs: Architected modular ERP management panels and built scalable, low-latency REST APIs powering iOS and Android mobile apps using Laravel (PHP 8.x) and .NET Core.
- Third-Party Financial Integrations: Integrated multi-currency payment gateways, banking APIs, SMS gateways, and enterprise ERP systems protected by RBAC, OAuth2, and JWT Bearer tokens.
- Contract-First API Delivery: Standardized contract-first API development using OpenAPI/Swagger specifications, accelerating frontend and mobile delivery velocity by 25%.
- Quality & Architectural Standards: Established comprehensive code review guidelines, relational database normalization practices, and automated deployment pipelines.
- Enterprise ERP Systems & Delivery: Directed modular architecture and backend engineering of ERP solutions (inventory, accounting, and workflow modules) with .NET and Laravel, managing end-to-end API design and production rollouts.
- Reliability & Automated Testing (xUnit & PHPUnit): Engineered automated unit/integration test suites with xUnit and PHPUnit and containerized deployment workflows (Docker), significantly reducing production regressions.
- High-Concurrency Web Services: Developed PHP and Laravel enterprise web services, optimized MySQL query execution plans, and configured Linux server environments with Nginx load balancing for high-traffic resilience.
- SaaS Cloud Platforms: Developed scalable multi-tenant SaaS cloud services and administrative portals using ASP.NET Core and PHP; led architectural refactoring and code quality enhancements across legacy modules.
- Contributed to relational database schema modeling, optimized core CRUD operations with C# and PHP, and supported development of initial REST endpoints.
