<h2>Nick Web Services (NWS)</h2>
|
|
<p><i>C#, Kubernetes, Rancher, and HAProxy</i></p>
|
|
<a href="https://nws.nickorlow.com">[ Project Website ]</a>
|
|
<p>
|
|
Nick Web Services is a cloud infrastructure provider service that I created and run.
|
|
It allows people to deploy containerized versions of their web apps across our multiple
|
|
servers. It provides geo-distributed high availability by default with no extra configuration
|
|
needed from users hosting their webapp with us.
|
|
</p>
|
|
<p>
|
|
Hardware-wise we use old Dell PowerEdge servers running Proxmox. We then have VMs running
|
|
in Proxmox that run Kubernetes clusters. We have 4 clusters currently: Austin, Hill Country,
|
|
Schuylkill, and Philadelphia. The deployments are managed through GitOps with Rancher Fleet.

<h2>Anthracite Web Server</h2>
|
|
<p><i>C++ & Python</i></p>
|
|
<a href="https://github.com/nickorlow/anthracite">[ GitHub Repo ]</a>
|
|
<p>
|
|
Anthracite is a simple web server written in C++. It currently supports HTTP/1.0 and HTTP/1.1.
|
|
The benchmarking tools for Anthracite are written in Python. Anthracite is optimized for performance
|
|
and rivals the performance of NGINX & Apache in our testing. It uses a thread-per-connection
|
|
architecture, allowing it to process many requests in paralell. Additionally, it caches all
|
|
files that it serves in memory to ensure that added latency from disk reads do not slow down requests.
|
|
Through writing Anthracite, I have learned to use different C++ profilers as well as some general
|
|
optimization techniques for C++.

<h2>CavCash</h2>
|
|
<p><i>C#, Kubernetes, SQL Server, and MongoDB</i></p>
|
|
<a href="https://cavcash.com">[ Project Website ]</a>
|
|
<p>
|
|
CavCash was a company that I founded which built a debit-based payment system similar to
|
|
PayPal and Venmo. I assembled a 5 person team and took on a technical role in the company,
|
|
writing most of our backend codebase. Our backend used C#, ASP.NET, Microsoft SQL Server,
|
|
and MongoDB. Our infrastructure changed throughout the lifetime of the company, initially
|
|
it was on Microsoft Azure using Azure App Service. We then pivoted to AWS using Elastic
|
|
Beanstalk. We also ran on Google Cloud Platform using Compute Engine. Finally, we setup our
|
|
own servers in-house and managed our deployments with Kubernetes.
|
|
</p>
|
|
<p>
|
|
We launched in 2021, with the ability to send money between real banks using the ACH network.
|
|
We ended up processing a few hundred dollars in transaction volume before ultimately shutting
|
|
down due to a lack of funding. The website is now back up and everything works as it did in
|
|
2021, except adding funds from a bank account is not supported.

<h2>SQUIRREL</h2>
|
|
<p><i>Rust</i></p>
|
|
<a href="https://github.com/nickorlow/squirrel">[ GitHub Repo ]</a>
|
|
<p>
|
|
SQUIRREL stands for SQL Query Util-Izing Rust's Reliable and Efficient Logic. It is a SQL database
|
|
that I am writing in Rust. Currently, it can create tables, insert data into tables, and select all
|
|
data from a given table. The biggest challenge so far has been writing the parser. My next steps are
|
|
to add WHERE clauses to SELECT statements, allow column filtering in SELECT statements, and add DELETE
|
|
statements.

<h2>Olney</h2>
|
|
<p><i>Rust, Postgres, Svelte, TypeScript, and OpenAI's API</i></p>
|
|
<a href="https://github.com/nickorlow/olney">[ GitHub Repo ]</a>
|
|
<p>
|
|
Olney is a job application tracker that aims to be better than using a <a href="https://trello.com">Trello</a> board or a spreadsheet.
|
|
It allows users to create jobs and log custom events such as interviews, assessments, and other communication.

<h2>SEPTA Site</h2>
|
|
<p><i>Svelte, TypeScript</i></p>
|
|
<a href="https://github.com/nickorlow/septa-site">[ GitHub Repo ]</a>
|
|
<p>
|
|
SEPTA Site is a website that I created which can get your trip history, SEPTA Key balance,
|
|
and ridership statistics for your SEPTA Key. It utilizes SEPTA's new metro wayfinding instead
|
|
of their current wayfinding. I wrote the project to get a basic introduction to Svelte and
|
|
so that I could try to improve upon the UX of SEPTA's current website and mobile app.
