I've found this stack incredibly powerful so I've written a post about my patterns and what I love about it. {{< figure src="/posts/infra/grafana.png" alt="grafana dashboard" >}} Basically, Terraform creates and destroys infrastructure, Ansible manages the OS-level stuff and then the services I run use docker compose. I use a _bootstrap_ Ansible role instead of golden images.

The technology has many applications for __AR/VR__ experiences like 3D sports and music events or smaller-scale applications like a 3D __Twitch__. The holograms are captured in the form of a __point cloud__, a cluster of coloured dots that, when presented correctly, can appear like the original object. {{< figure src="/images/holo-avatar.jpg" >}} My undergraduate dissertation documented extending the [__LiveScan3D__](https://github.com/MarekKowalski/LiveScan3D) holoportation platform to allow multi-source streaming. The existing capabilities allowed a single scene to be captured in real-time and streamed elsewhere for viewing, multi-source allows multiple independent scenes to be received and composited at the same time (a many-to-one system). {{< youtube NP0aVjuk5fU >}} [Read More](/holo) {{% image-box-link src="/posts/draught/checkers-board.png" href="/posts/draught" title="Draught" caption="Rust + Js" %}} {{% image-box-link src="/posts/game-of-life/gameoflife1.png" href="/posts/game-of-life" title="Game of Life" caption="Rust + Js" %}} # [Mixonomer](/mixonomer) `Python [Flask]` `JavaScript [React]` Mixonomer is a web app for creating smart playlists for __Spotify__. These playlists watch other playlists to use them as sources of tracks. These tracks are filtered and sorted before updating a __Spotify__ playlist. Updates are run multiple times a day or on-demand. Additionally, __Last.fm__ integration provides listening statistics for your playlists. {{< figure src="/posts/mixonomer/cloud-structure-3.png" alt="cloud structure" >}} The project began as an exercise in recreating the functionality of [__Paul Lamere‘s__](https://twitter.com/plamere) [__Smarter Playlists__](http://playlistmachinery.com/) app. This tool had become a really important part of my daily listening habits as a way of combining my smaller sub-genre playlists into larger mixes. The app has a __Python__ back-end written in __Flask__. The front-end was built using a __Node + Webpack + React__ stack. The system is now deployed with a fully serverless architecture.

I wanted to explore what insights could be found in my 3 years of __Last.fm__ scrobbles when augmented with __Spotify__ data. Ideally, I also wanted to be able to apply the intelligence to the __Mixonomer__ playlist pipeline. __Spotify__ provides audio features for the tracks on its platform. These features describe a number of qualities for the tracks including how much energy it has and how vocal it is. I investigated whether the set of audio features for my larger genre playlists could be used to classify tracks by genre.

Day-to-day this is in [__C#__](/holo/) and [__TypeScript__](/mixonomer) but I also like working with [__Python__](/mixonomer) and [__Rust__](https://github.com/Sarsoo?tab=repositories&q=&type=&language=rust&sort=). I keep all of my projects on [![GitHub](https://img.shields.io/badge/github-%23121011.svg?style=for-the-badge&logo=github&logoColor=white)](http://github.com/sarsoo). Alongside development I also enjoy working on infrastructure, I have 5 years experience using __Linux__ and managing networks. I have experience working with cloud technologies – from [__virtual machines__](/holo), [__web server PaaS__](/mixonomer) and [__serverless functions__](/mixonomer) to [__NoSQL__](/mixonomer), Big Data SQL and [__pub/sub messaging__](/mixonomer). Much of this experience was gained during my [__Mixonomer__](/mixonomer) project and during my __Disney__ internship. As part of my [dissertation](/holo#research), I used a global cluster of virtual machines as an environment to measure and experiment with holographic video QoS over long distances. At university, I was particularly interested in the software side of the field including modules in __programming__, __signal processing__ and __AI__. I also took a set of modules in __semiconductors__ and __nanoscience__. [Posts](/posts) --- # Awards Throughout my time at university, I earned multiple awards for academic achievement - ___Dean’s List for Academic Achievement___ (2018) - Awarded for overall academic performance as part of my international exchange program with the [__California State University, Los Angeles__](https://www.calstatela.edu/) - ___Lumentum Award___ (2020) - Awarded for achieving the __highest mark__ in my third year __Semiconductors & Optoelectronics__ module - ___Atkins Best Oral Presentation – 2nd Prize___ (2021) - Awarded for giving second best oral presentation for ___multi-disciplinary design project___. Project involved designing a fully renewable ship and depot to repair sub-sea fibre optic cables.
