From curiosity to career

I started writing code because I wanted to understand how things work — and I never stopped. Over 8 years building production systems, I’ve debugged enough midnight incidents, optimized enough slow queries, and untangled enough legacy codebases to know where the real pain points are.

That experience is exactly what CodeSolved.dev is about. Not theoretical tutorials — practical solutions to real problems, written by someone who runs into the same issues you do.

What this blog is about

Practical problem-solving

Real scenarios from real projects — not toy examples. If I’ve spent hours debugging something, I write it up so you don’t have to.

Deep dives

Topics like Elasticsearch internals, .NET performance, and SQL query optimization — explained from the inside out.

AI in development

Honest takes on using AI tools in a senior developer’s workflow — what actually helps, what doesn’t, and how to stay sharp.

Video walkthroughs

Many articles are paired with a YouTube video where I code through the solution live. Subscribe so you don’t miss them.
