What I'm looking for

I’m looking for a role where I can design secure .NET back-end APIs, integrate payments and third-party services, and keep improving reliability and performance—while working closely with others and learning continuously.

I’m a software developer who enjoys turning ideas into reliable and practical software, and I like being involved in every stage—from understanding the problem to delivering the final product. I take pride in writing clean, maintainable code and contributing to projects that make a difference for both users and the team. In my roles, I’ve designed and developed backend services and RESTful APIs using ASP.NET Core and Entity Framework Core, while focusing on security, scalability, and long-term stability.

I’ve built real-world workflows such as payment and invoicing processes by integrating banking and payment providers (e.g., Network International, Geidea, Ruya Bank, Fuze), and I’ve implemented operational dashboards for reporting and real-time monitoring. I also integrate third-party services (SMS gateways like Mobildev, Google Maps API, identity providers, email providers like SendGrid, and services like Stripe) and use background jobs with Hangfire for scheduled tasks and recurring operations. I’m motivated by solving real challenges, working closely with others, and constantly learning—and I’m especially drawn to environments where I can take ownership of secure authentication, role-based access, and high-performance data layers with PostgreSQL/MSSQL.
