A video editor that you can use in the browser. It enables users to create high-quality videos intuitively, all in the cloud. I was a full-stack developer and worked on all aspects of the software. I worked on everything from the front end, which included editing the video, to the back-end work, developing the FFmpeg framework needed to render the videos in full HD.

- As the lead developer, Razvan was in charge of the software development team
- Razvan developed the architecture for both the API and the interface
- He is also in change with understanding the client's needs and adapting the product accordingly, in a cost-effective manner.

Squired connects restaurants and their customers.

OUR VISION
• We want to make people go out to restaurants.
• We combined a great idea with technology to connect the restaurants and the client.
• We wanted to empower the restaurants to earn time by using Squired and help them find out what the customer thinks about them.

THE IDEA
• To make people go out and move, we identified the problems the customer deals with, and we created Squired.
• We also researched and created different features to make the restaurant's customers use the app: special offers, events, ratings, reviews, etc.
• We wanted to provide the restaurants with important statistics about their business: how they position themselves in the market, customer satisfaction, what they think about the brands, etc.

This live video streaming service gives users the ability to control a PTZ camera. It has four main parts:
1) a local control server for the camera
2) a REST API server
3) a streaming server, and
4) the front-end. All are connected through a VPN; the front end connects to the API and stream server via WebSocket.

The cameras encode h.264 HD vi is sent to a local control server that re-encapsulates the stream and sends it to the stream server. Without involvement, the local server can be low-powered and handle many cameras. If power is lost, the server automatically searches for cameras via NMAP and broadcasts it to the API.

The stream server sends the received stream via WebSocket to the front end that displays it using Broadway. The stream is sent to the user with little latency ( around one second) and allows users to see the camera movement quickly.

The system supports multiple connections placed in a queue and waits for the camera to become available.

All servers ran Docker containers. The local server ran PHP, the stream server ran Node.js, the API was Ruby on Rails, and the front end was either Angular or vanilla ES5 JavaScript.

As a 3D modeler, Razvan developed and designed a virtual ski resort in the Carpathian Mountains, which was required for a pre-feasibility study. It was a big project covering a couple of square kilometers. It was developed entirely in Google Sketchup with the help of Photoshop and Google Earth.
