Employment
Experience
- Oriolyhttps://www.orioly.com
Orioly is a booking and marketing SaaS that helps small tour agencies and activity providers manage their business, optimize costs, and quickly start selling their tours and/or activities online.
I acted as the lead front-end developer on this project. Most of my work consisted of designing and developing the front-end code base. - Orioly | Booking Enginehttps://www.orioly.com/
This booking engine which was created for the platform Orioly enables tour agencies and activity providers a quick-and-simple way to market and sell their tours or activities online by placing a book-now button on their website.
I designed and developed the booking engine from scratch using AngularJS and cross-domain messaging as a way of communicating with the server. I also implemented the following payment gateways: PayPal Adaptive Payments, Stripe, and Mercado Pago. - Orioly | Mobile Booking Application for B2B Users
Orioly is a business system for tour and activity providers, and for that purpose, we built a mobile app which can be used by agents, suppliers and other resellers who want to make additional sales.
This mobile app is a React Native product which provides an option for simple booking on the spot, a scanning voucher, and a way to check reservation status.
I was this project's lead engineer and it was built in less than three months. - Klikkie (Toptal)https://www.klikkie.nl
Klikkie is an app that enables customers to order quality printed photos in a few clicks.
My main focus was working on the client-side React application—namely, rewriting/restructuring the app using best practices, removing performance regressions, connecting the app to the Google Photos (Picasa) API and doing consulting work. - Moment-Randomhttps://github.com/imrvelj/moment-random
A small NPM library which generates a random Moment.js object.
