Software developer / New York

Aidan Decina

I finished my computer science degree at Marist in May 2026. Since then I have been freelancing. Right now that means a sales dashboard for a gas station in Brewster, and a handful of C++ and TypeScript projects where I rebuilt things like a web server and a database to figure out how they actually work.

Desktop app

Brewster Gas Corp

I built a Sales intelligence Dashboard for a gas station. The owners wanted to understand what had the greatest impact on gasoline sales and profits. They wanted to improve gross profit by making better and more informed pricing decisions. I discussed how a dashboard could help them make decisions based on data instead of guessing. To do this I developed a dashboard that combined sales data with owner pricing, competitor pricing, weather, school schedules,holidays and local events to see trends, patterns and how these variables interact to impact their sales and profits.This dashboard serves as a daily decision support tool that can identify opportunities, explain changes in performance, predict future demand and improve sales volumes and profit.

Emulator

MOS 6502

18 instructions

Emulator

tsiraM

An emulator for the 6502, the processor in the original Nintendo and the Apple II. I wrote it for my computer architecture class. Instead of finishing an instruction all at once, it moves one step forward per clock pulse, so you can watch instructions overlap the way they do on the real chip. I got 18 instructions working.

Web server

C++

No framework used

Web server

HTTP server in C++

I wanted to know what Express is doing underneath, so I wrote a web server without one. It reads the raw request text and figures out what was asked for, handles several people connecting at the same time, keeps connections open between requests, and compresses what it sends back.

Database

C++

Works with redis-cli

Database

Redis clone in C++

A rebuild of Redis, which is the database a lot of apps use for caching. I matched how it talks over the network closely enough that the official Redis command line tool connects to mine and works normally. It handles several clients at once, keys that delete themselves after a set time, and lists.

Web app

StockSim

A trading simulator that uses fake money and real prices. You buy and sell, and it keeps track of what you own and how you are doing. The prices come from live market data, so it moves the way the actual market does during the day.

Web app

Kanban task board

A shared task board you can drag cards around on. Most of the work went into the database rather than the interface. Moving a card only updates that one card instead of renumbering the whole list, people can only see boards they belong to, and the history of who changed what is written by the database itself so it cannot be faked from the app.

Game

Game

SpellForge Showdown

An arena game built in Unity where you fight using spells you put together yourself. The game itself is finished and playable. I started building a separate server so two people could play against each other online, but I did not finish that part.

About me

I studied computer science at Marist and graduated in May 2026. My concentration was game design, though most of what I build now is backend work.

When I want to understand how something works I usually try to rebuild it. That is where the web server and the Redis clone came from. It takes a lot longer than reading about it, but I remember it afterward.

I am freelancing at the moment and looking for a full time software job. Happy to talk about anything, but I am most interested in backend and systems work.

Based in: Hudson Valley, New York
School: Marist UniversityBS Computer Science, 2026
Mostly working in: C++ and TypeScript
Looking for: Full timeNew York area or remote
