About myself
During my twelve years of professional experience as a software engineer, I have gained proficiency across a wide range of languages and architectures –
from low-level C/C++ trading tools to PHP/Java web applications and most recently, native iOS and Android mobile development.
In an industry that completely reinvents itself every two years; I have found the ability to adapt to be invaluable and my breadth
of experience instrumental in avoiding common pitfalls, scalability issues and stack oversights.
For the past nine years I have become increasingly versed in mobile app development, designing and launching over a dozen native iOS and Android apps
grossing over three-million combined downloads. I am proficient in Objective-C as well as Swift and am always studying the latest advancements
in architecture and code design in order to maximize efficiency, reusability and test coverage.
A bit more extroverted than your typical engineer, I excel in mentoring fellow developers, managing projects and
leading my engineering teams to exceed expectations. I pride myself on the ability to communicate not only with engineers but also with users, clients
and less-technical members of the business world alike.
I am currently looking for an architect, team lead, or senior iOS role with an innovative tech company or startup but I am always open to new adventures.
Full-stack and growth opportunities are not out of the question. A friendly company culture and a challenging mission are more important to me than any specific
industry or product.

Project Portfolio
Mobile App Development
SALIDO - Point Of Sale (iOS)
(Enterprise Only)
Designed to work as a standalone POS or "hot swappable" within a fleet, this app has over 500 operating modes and feature toggles. To achieve the needs of almost any restaurant environment out there,
the source code quickly became a highly complex beast. While most apps off-load business logic to the server side, we often found ourselves doing the opposite; allowing the app to
operate under even the most adverse network conditions with near 99.999% fault tolerance. This app pushes the hardware limits of even the latest model iPads and I'm proud to have
lead its development.
CooCoo (iOS/Android)
In April 2011 I was hired by CooCoo to help build out their mobile application platform
from the ground-up. The first task was to convert the back-end of what had been until then a text-message based
system into a secure and scalable API. I then developed CooCoo's primary mobile app natively for both iOS and
Android.
Citi Gold (iOS)
During a 9-month contract at Citibank I was a member of the newly minted FinTech division, tasked with developing Citibank's "Gold" iOS app: a feature rich extension
to their original "blue" app for high-net-worth investors. I served as technical lead for one of three "Invest" teams; designing the trade execution and
general security layer for the MVP.
Light It Up Blue 2012 (iOS/Android)
During a brief lapse in start-up funding while working for CooCoo, my expertise was loaned out to our VC-backed sister company that
specialized in micro-site development for non-profits. During this time, I was tasked with developing
both the native iOS and native Android editions of Light It Up Blue (2012) for Autism Speaks.
SALIDO - Kitchen Display System (iOS)
(Enterprise Only)
The restaurant kitchen is one of the few places technology has failed to penetrate. The KDS app is SALIDO's answer to this conundrum; providing
real-time food prep, inventory and management to full-service restaurant kitchens via an iPad app that seamlessly integrates with SALIDO's award winning POS.
CooCoo Ticketing (iOS)
Not publicly available (Enterprise Only)
One of the more innovative projects I worked on while employed at CooCoo was the development of a mobile-based POS system for accepting
payments and validating tickets onboard commuter railroads / buses. The concept utilized an enterprise iOS app paired with a fleet of
LineaPro devices capable of scanning barcodes and swiping payment cards. Users could also purchase tickets through our many iOS/Android
apps that were custom-tailored to each transit provider.
Video Dating App (iOS)
Not yet released (under NDA)
In 2014 I was hired by a private firm to develop an iOS video-based dating app. While the MVP is complete and in beta, the app
has not been publicly released and remains under non-disclosure agreement so I cannot
divulge much about its features. I was the sole architect of the app itself and the server platform that drives it.
In 2016, I divested myself of the project in order to focus on full-time employment.
HolyQuotes (iOS)
In 2012, my boss at the time bet me $1000 on a Friday afternoon that I could not develop a useful app in a single weekend
...and thus Holy Quotes
was born the following Monday. After creating a shell script to parse meaningful quotes from a digital copy of the King James,
I spent the remainder of the weekend designing the app's interface. The finished app generated 10,000 downloads in its first month.
I feel the need to note that I am not a particularly religious person; the concept simply struck me as useful.
Website Development
World Steel Dynamics
Developed from scratch while working full-time for World Steel Dynamics Inc. Beyond advertising the company's primary business, a pay-walled client area hides a secure report access system and a custom-designed account management & billing portal coded primarily in PHP.
DBC Corporate Website
While working at SSNC, I was tasked with revamping the Municipal Finance Division's corporate website. Utilizing PHP and Python, it housed a large paywall area for clients and a API back-end to interface with DBC's fat-client database software.
Sammy & Nat
Originally built using open-source e-commerce platform Opencart, I constructed SammyAndNat.com in a matter of months for my friend Samantha Benson to retail her line of fashionable baby rampors.
Facebake
Coded in a single summer post college using the open-source social networking engine Elgg, facebake.com was one of my early "million dollar ideas" that didn't quite pan out as I had hoped. Though the user base has moved on, the site and the concept still make for humorous cocktail conversation.
Albanytakeout
One of the more profitable of my personal website endeavors, I built Albanytakeout during my sophomore year of college and its visitor numbers have steadily increased ever since. It's basically a query able database of restaurant menus in Albany, NY.
Global Tradeflow Demo
For the purpose of showcasing my work in quantative programming on large data sets, I extracted a single module of the GSIS suite and converted it to a functional demo. I scrambled the original data to avoid giving away a proprietary software tool but it is otherwise fully functional.
Dreamware Systems LLC
A simple company site built to showcase my abilities as a self-employed software developer. While the site is still live, I have since abondoned moonlighting work in order to focus on full-time employment.
CooCoo
While primarily tasked with developing the mobile app platform at CooCoo, the lean start-up culture dictated that I lend a hand anywhere it was needed, including with their website presence. I cannot take full credit for the site design as it was a team effort.
GSIS Interactive System
While working at WSD full-time my primary task was maintaining and enhancing an online suite of market forecasting and analysis tools known as the Global Steel Information System. While development of the site was a team effort, I was personally responsible for coding 3 of the 7 final modules.
Student Groove Card
The first commerical website I was begrudgingly coersed into coding. Please don't judge it based on the table-based layout, I was largely ignorant of web development techniques at the time. I include it here only to show how far I've come...
Personal Resume Website
This one is self-explanatory given the context... The neat thing is that the source code is available below
