Vladislav Rajtmajer
Senior PHP / Laravel Engineer
vladislav@rajtik:~$ cat about.md
12+ years building web applications and backend systems. I work mostly in
Laravel: REST and user-facing API design, PostgreSQL, and the boring
reliability work that keeps APIs predictable.
Before the web I spent years in embedded and IoT: binary protocols between hardware and servers, telemetry data pipelines, even banknote-validator firmware in C on Atmel AVR. That low-level background still shapes how I design data interfaces.
# Open to long-term remote contracts on a modern PHP/Laravel stack.
