The most amazing...
...project I've joined was one with a new team that needed to be delivered in just three months; we were able deliver in time while having a very good time!
Work Experience
Senior Front-end Developer
Toptal Client
- Collaborated with ten team members on a dashboard re-platform project from AngularJS to Vue3, including writing from scratch our own reusable components library to be available for other company projects, too, with a focus on accessibility.
- Mentored up to four people in Vue.js and front-end development in general, including leading a three-people bug crushing squad.
- Oversaw the launch process, which was done on a per-customer basis by making features selectively available via feature flags, and responded to customer requests or concerns while proactively reaching out to stakeholders.
- Cross-collaborated with other teams, both front-end, and back-end, including API development and even solving DB issues.
Front-end Developer
Toptal Client
- Developed and delivered a working MVP for an administration dashboard.
- Worked as a sole front-end developer, fully responsible for every aspect of the front end.
- Collaborated with a back-end developer, scrum master, and UI designer.
Front-end Developer
Qomplx
- Developed a dashboard tool using different visualization libraries such as Cesium.js or Charts.js, and integrated various APIs and data types into a useful report.
- Dug into a very particular multi-time-series and geographic DB and its API, and modified map visualization libraries such as Leaflet.js or Cesium.js to show this data.
- Became part of a newly created team to deliver a product in just three months. I learned a new tool to be used and adapted. I worked together with the technical lead and participated in various client meetings. We were able to deliver on time.
Full-stack Developer
Osom Digital
- Served as the technical lead of a team of five for an eCommerce project.
- Maintained tasks for a deployed project after learning PHP and the Laravel framework to cover for an absent back-end developer.
- Oversaw the outsourcing of an iOS app for an eCommerce project as we didn't have the manpower to develop it ourselves.
Experience
Open Platform for Movie Restoration
I developed various algorithms for restoring old movies, such as detecting movie cuts, flicker correction, and detection and restoration of scratches.
The technologies involved for this end were mainly C++ and the OpenCV library and were published as plugins for Natron.
