Software Architecture Developer in Kraków, Poland

Software that I created for stadiums and venues requiring accreditation of VIP and media persons for events. It includes complex business logic and rules for automatically generating tickets, zone access information, and parking pass information.

I was a part of a team in 2006-2007 that developed and supported the database layer and API of this event management system.

Software for a vending company for services/deliveries and sales. It contains two parts: a web application for back-end employees, and a mobile application for service engineers, deliveries engineers, and salesmen. The mobile app can work both off- and online. It syncs with a Node.js server and communicates via sockets. The back end is a REST API based on Laravel framework. The mobile app was created with Sencha and PhoneGap. The web app created on Sencha framework.

The software supports many clients and is preparing to launch to customers for the delivery of goods and security companies.

Call center management software. I worked as a PHP developer, adding new features, correcting errors, improving the database structure, optimizing code, and modifying the system of rights for the project.

I helped to refactor the existing platform architecture design as well as write the REST API, unit tests, and documentation. The project is a big eCommerce solution that supports an unlimited number of merchants and webshops (like eBay).

A multi-client LMS that allows for the construction of a client's specific sites to sell and set up courses with various components (webinars, quizzes, surveys, certificates, discussions, etc). After COVID appeared, we adapted it to organize virtual conferences. I've been working on it since May 2015, when the project was built on Laravel 4. I've developed and refactored almost every module in the system, helped to migrate to Laravel 5, and contributed to the last update to version 6 of the framework. A lot of development challenges related to refactoring/migration/high loads were involved.

Tech stack: Laravel 6, jQuery, MariaDB, Beanstalkd

Between May 2018 and December 2019, I helped develop a local management tool for a large company selling and then supporting computer hardware and servers. We migrated data from the old system to a new one built on Laravel 6. The front end was built on Vue.js/Vuetify. A service layer was developed for exchanging data with the old software (SICLOPS) and additional databases. Also, a module was created for managing the stocks in warehouses, movement, sales, and purchases with the ability to track parcels. Reports were created to optimize stock balances.

Tech Stack: Laravel 5, Vue.js/Vuetify, Algolia

I helped develop an application to support engineers, which allowed accepting a task from an active pool, going to the client's site, and reporting on its completion. We tracked the location, showed the estimate, and allowed uploading scans and images of problem equipment as well as asking clients for a signature. The app could work offline. In addition, administrators received a dashboard for managing engineers.

Tech stack: Laravel 5, Vue.js (using service worker to support offline mode), Laravel Nova (admin dashboard)

A wedding site built for my wife using Laravel 7/Vue 2 for the public site and a simple CRM using Laravel Nova to manage contacts/leads and a media library. The project is under constant development and is used for tests and experiments in this tech stack.
