What I'm looking for

I'm looking for a backend development role where I can keep building scalable .NET applications, contribute to clean and secure systems, collaborate through code reviews, and grow with experienced engineers.

I'm building .NET web applications including an Online Voting Application, ShopIQ SaaS e-commerce platform, Thinkly School Management System, SabiSpace, and a Church Management System.

I develop backend services with C#, ASP.NET Core, REST APIs, PostgreSQL, MSSQL, Entity Framework Core, LINQ, authentication, authorization, caching, Redis, RabbitMQ, and asynchronous programming. I focus on clean architecture, scalable systems, secure code, query optimization, and maintainable business logic.

Alongside software development, I've taught Mathematics, Physics, Chemistry, and Economics, provided private tutoring, and supported emergency search and rescue operations with the National Emergency Management Agency.
