Why Hire Me

Business-Aware Developer

I understand both the technical and business sides. My SaaS support background means I write code with real users in mind — not just passing tests.

Practical Full-Stack Skills

From ASP.NET Core APIs to React frontends and SQL Server databases, I build complete, working applications — not just isolated components.

Strong Communicator

I explain technical concepts clearly, write solid documentation, and collaborate well across engineering and non-technical teams.

Fast Learner, Self-Driven

I've built multiple full-stack projects independently, earned certifications on my own time, and consistently take initiative to grow my skills.

About Me

Who I Am

I'm a Junior .NET Developer based in Mississauga, Ontario. I build full-stack web applications using ASP.NET Core, C#, Entity Framework Core, and React. I'm passionate about clean architecture, solving real problems through code, and continuously growing as an engineer.

How I Work

  • Break down the problem before writing a single line of code
  • Build with clean architecture, MVC patterns, and SOLID principles
  • Validate with Postman, Swagger, and SQL — test before shipping
  • Communicate clearly in code reviews, standups, and documentation
  • Iterate based on feedback and keep improving

Let's Build Something Together

Open to Opportunities

I'm actively looking for Junior .NET Developer, Full-Stack Developer, or Software Developer roles where I can contribute to real products, grow with a strong team, and keep building my skills in C#, ASP.NET Core, and modern web technologies.
