.NET Tech Lead | Cloud Architect(AWS) | FinTech & Enterprise Solutions

I build rock-solid, scalable software solutions 🚀. With over 15 years of experience in the tech industry, I don’t just write code, I act as your Software Partner. I specialize in the .NET ecosystem (C#, .NET Core) and have a proven track record of creating high-impact, secure applications for the finance, banking, and core operational sectors. ​I thrive on solving complex business problems, translating them into resilient, cost-effective architectures. Whether it's decoupling legacy monoliths or building cloud-native microservices from scratch, I deliver reliable, clean systems that scale. ​Let's build something great together. How can I help you? 🤝 ​🎯 Backend & API Development: I build robust, highly secure RESTful APIs and distributed systems using Clean Architecture and Vertical Slice patterns. 🎯 Cloud & System Architecture: I design scalable, event-driven architectures (AWS EventBridge, SQS) ensuring long-term growth and high performance. 🎯 Data & Database Design: I create optimized data layers using relational (PostgreSQL, SQL Server) and NoSQL (DynamoDB) solutions to ensure absolute data integrity. 🎯 Future-Ready Integrations: I architect highly decoupled backends capable of securely integrating modern AI solutions and third-party enterprise tools into your workflows.
