Arnold is an experienced Senior PHP Developer with a demonstrated history of working in the information technology and services industry for 14+ years. He is skilled in backend service systems and cross-platform solutions, working with leading software companies in multiple industries and completing over 30 projects. His latest project involved developing backend systems for electronic vehicle blue-box data processing for a navigation software company.
The project involved creating a site that controls an API rate limiter for OSM tile servers. Developed the whole logic for the application. Users have a quota for each of the API types, granted by the admin, then the users can create API keys for each API type. The system is developed to handle ~7000 requests per second on a standalone server - without a load balancer.
NetPincér is a delivery platform for Hungary having 4000+ partners nationwide. I worked for several years on this project, handling backend communication, MQ system management, MQTT communication to support the customer support facility with event-driven solutions, and connect the whole system to the DeliveryHero main Salesforce system.
REDWood Offices is a psychological and training center in the immediate vicinity of Gellért Square, yet in a quiet, peaceful environment. The project is a small conference reservation business. They've outgrown the previous reservation system and needed a new, more flexible one. They use a lot of custom pricing and discounts. With this system, they can handle it all in one.
