}I am a Senior Software Engineer & Solutions Architect with 8+ years of experience designing, modernizing, and scaling mission-critical enterprise systems, core banking platforms, and fintech engines.
- 🏦 Financial Systems & Core Banking: Modernized monolithic financial cores into event-driven microservices using the Strangler-Fig pattern, outbox messaging, and immutable financial ledgers.
- ⚡ High Throughput & Low Latency: Engineered wallet & payment APIs handling 1,000+ TPS with sub-40ms transaction response times.
- 🔄 Event-Driven Resilience: Extensive experience with Apache Kafka, RabbitMQ, CQRS, and Domain-Driven Design (DDD) to guarantee zero data drift and idempotency.
- 🌐 Modern Full-Stack Engineering: Architecting enterprise-grade backends in .NET 8 / C# & Node.js combined with reactive frontends in Next.js 16, React 19, & TypeScript.
