About
Dimitar Kalinov
Senior PHP developer and tech lead. Plovdiv, Bulgaria. Working remotely with teams across Europe and beyond.
I have been building and maintaining web applications since 2007, mostly in PHP, and for most of that time on systems that were already in production when I arrived: an IP address management platform used to automate corporate networks, a ticketing platform with live seat selection and refunds, a payment platform processing more than $10M a month, and real-time location systems for manufacturing.
That work taught me to respect running code. I read before I change, measure before I optimize, and prefer a boring, reversible step over an impressive one. As a tech lead I have also owned architecture, deployment and mentoring, so I am comfortable working with your team rather than around it.
I combine close to two decades of software engineering experience with modern development tools, including AI-assisted coding and analysis, where they genuinely improve the work.

Tell me about the system
A few lines are enough: the PHP version, the framework, roughly how large the codebase is, and what is hurting right now. I read every message myself and reply with questions, not a pitch.
