At AppFactory I worked on multiple projects (web services, APIs, mobile apps):

• bevvy.com — Is a mobile application for recognizing whiskey bottles via camera. I worked on the project, including improved the search, implemented push notifications and made API documentation with Swagger.

• fanstickerz.com — Officially licensed digital stickers for export to messaging platforms. I brought the startup project to working condition, implemented new features, prepared API documentation.

• order.bg / zavedenia.com — The restaurant aggregator of orders and reservations. I rewrote the old system on a new stack (Laravel 10), fully implemented the backend logic, including integration with external APIs. I added online payment, sending SMS, calls and messages via third-party APIs.

• ordermoon.com — Application for couriers in restaurants. I fixed business logic of discounts, added push notifications.

• banskoblog.com — Ski resort booking site. I added payment system integration (MyPOS, Opennode). Technologies: PHP 5.2–8.4, Laravel 7–12, MySQL/PostgreSQL, Redis , AWS, Firebase, Swagger, Google Maps API, Vue.js, Docker, GitLab CI/CD, Bitbucket Pipeline.

At Home Shopping Russia, I created API services to transfer business logic from a Lotus Notes CRM monolith to a Laravel and Slim Framework microservices system. I also wrote a Laravel websocket server for real-time client data exchange and integrated third-party APIs.
