Software Design Portfolio

Computer programming is about much more than just building websites and mobile apps. It’s about creating all sorts of computer software applications, from analyzing rocket motors and Space Shuttle flights, creating order entry and reporting systems, manufacturing software, and much more, including the applications shown on this page.

Primary Skills

To be clear, I believe my primary skills are:

• Leading software development teams as a ScrumMaster and Product Owner
• To that end I am a Certified ScrumMaster (CSM) and Certified Scrum Product Owner (CSPO)
• Software requirements and design (i.e., Business Analyst and Product Owner)
• Server-side programming
• Cross-platform mobile app development with Flutter

Background

That being said, I think it’s also important that you know my complete software development background. Therefore, this page is separated into the following three sections:

• My software analysis, requirements, and design portfolio
• My software application portfolio
• My website design portfolio

1) Software requirements, analysis, and design

Creating software is about much more than just sitting down and writing code. It’s about working with customers to deliver the system they want through a process of gathering system requirements and designing a complete software system to meet their needs. I’ve written thousands of pages of software design specifications.

Here are just a few images that demonstrate my experience in the field of software requirements, analysis, and design, formally known as Object-Oriented Analysis (OOA) and Object-Oriented Design (OOD):

A sample network diagram from an application I designed	A simple firewall diagram for one of my clients
A list of objects and relationships for a client application	A list of acronyms used in one of my projects
A list of actors for a project	A list of use cases for one actor
Another list of use cases for one actor	A small sample user story
A sample UML Activity Diagram	A portion of a model for a self-healing application
The physical architecture for a project named SAM	The test architecture for a project named SAM
A sample web form from an application prototype	Another web form prototype for a client application
A simple address lookup form prototype	A simple form to add a new address
A form to edit a barn door	Another barn door edit dialog
Part 1 of a container distribution form	Part 2 of a container distribution form
A portion of a UI palette	A plate view for a gatefold
Card wizard Part 1	Card wizard Part 2
Card wizard Part 3	Card wizard Part 4
Card wizard Part 5	Card wizard Part 6
Envelope wizard Part 1	Envelope wizard Part 2
Envelope wizard Part 3	Envelope wizard Part 4
Part of a polywrap wizard with text and annotations	More of the polywrap wizard
A sample data entry form with some complexity	An early prototype for the Nagios web interface

These days I generally work with “agile” software development methods like user story mapping and writing user stories, but if necessary I can also work with Unified Modeling Language (UML) approaches to software documentation.

2) Software Application Portfolio

While I have worked with other people to design and develop websites, that’s not what I normally do. What I normally do is design and build software applications. These days that include web applications and mobile apps for iOS and Android, and the occasional desktop application. Here are a few examples of my work:

TypewriterFX, a MacOS application that plays typewriter sound effects as you type	A sample iPhone form
Wikistar - An advanced text editor	NetAssist - A network analyzing app
A web form, part of the web interface I wrote for Nagios	Just Be, an Android mindfulness app
Part of the FLiB browser UI	Part of an early Twitter app I created
A scratchpad, multi-tab text editor	Part of my FPTracker application
An early screen from my Android football game	A later screen from my Android football game
A URL list in my URL-shortener web application	An early screen design for my RadioPi project
The main screen from my Cato CRUD Generator	Cato CRUD Generator with generated source code
Java Eyes - The famous Xeyes application, written in Java	Mac Automator apps and workflows

Here’s an image from my Back To Now app:

As you can see, I’ve designed and developed much more than just websites — I’ve created all sort of custom software applications. For even more applications, see my free software applications list on my alvinalexander.com website.

3) My website design portfolio

Technically I’m a programmer, not a designer, but this is a collection of websites I’ve designed. I created each of these websites shown below for very different purposes, and very different audiences:

• AlexanderKY.com — Support my (Alvin Alexander) previous computer programming business in Kentucky
• AlaskaSquirrel.com — A children’s story about living in Talkeetna ... with a squirrel
• devdaily.com — A very popular website for software developers and Linux geeks (receives millions of page views every year)
• HowISoldMyBusiness.com — A personal diary about how I sold my last business
• OneMansAlaska.com — A blog about my life in Alaska
• Sleetmute.com — A Function Point Analysis software program

devdaily.com - programming tutorials	how i sold my business (diary)
one man’s alaska (living in alaska)	alaska squirrel (a children’s story)
alexander consulting	sleetmute.com - function point analysis software
code me! - a tag-based search engine	matsuvp.com — the original Valley Programming website, when I lived in Alaska

While some of these websites are based on templates (see my Clean, minimalist Drupal themes and Clean, minimalist website designs articles on the devdaily website), I try to make each website unique and appropriate for the client and content.

4) Books

In addition to writing over 40 applications and several thousand blog posts on alvinalexander.com, I’ve also written over 3,000 pages of books.

Scala Cookbook (1st and 2nd editions)	Functional Programming, Simplified (Makes FP understandable)
Scala Book (1st and 2nd editions) (For the official Scala website)	Kotlin Quick Reference (Currently in progress)

Summary

I hope this small collection of diagrams helps demonstrate some of my software application analysis, design, and programming capabilities. To see even more about my most recent work, see the long list of apps I have written and the blog on this website.
