Deniz V.

I’m a Senior Backend & Systems Engineer with 15+ years of experience designing, building and improving production systems. I work best on problems that need more than implementation: understanding the real business need, designing the right technical solution, and taking it all the way to production. My background is primarily in backend engineering, data-intensive systems, APIs, databases and automation. I’ve worked extensively with PHP, MySQL, PostgreSQL, Redis and JavaScript, but I’m not tied to a particular framework or library. Once I understand the architecture and the problem, the specific stack is rarely the difficult part. AI is now part of my default engineering workflow. I use AI throughout system exploration, implementation, refactoring, debugging, testing and code review. It helps me move significantly faster, while architecture, trade-offs, reliability and maintainability still remain engineering decisions. I can help with: • System and backend architecture • Turning business requirements into technical solutions • Complex backend feature development • APIs and third-party integrations • Database design and optimization • Data processing, ETL and reporting systems • Automation and internal tools • Refactoring and modernization • Existing and legacy codebases • AI-assisted engineering workflows • Debugging complex production issues I’m comfortable entering unfamiliar systems, understanding how they work, identifying what actually needs to change, and delivering without unnecessary rewrites. Frameworks change. Libraries change. The important part is understanding the system, making good engineering decisions, and shipping something that works reliably. If you have a complex backend problem that needs both architectural thinking and fast execution, let’s talk.
