01. About Me
Azer is a backend-focused developer currently building iGaming platform services at Sportradar in Mostar, after three years shipping C# / .NET backend systems at CorNet. His core work is designing databases, APIs, and deployment pipelines that hold up in production, and he carries that same ownership beyond the API boundary — designing the frontend and handling deployment on projects that need it, so the product ships complete.
Outside of client and employer work, he works for Codeist as a backend consultant and developer, founded a short web-development course ("Web Element") to teach HTML/CSS and later C# .NET fundamentals, and still gives private lessons to IT students who are stuck on a concept. He likes AI-assisted tooling for the boring parts of the job — query tuning, test scaffolding, code review — so he can spend more time on the parts that need judgment.
