Ionic has always been one of my favorite frontend libraries. Its versatility in creating SPAs, PWAs, and mobile binaries for iOS and Android are nearly unrivaled. This material library provides access to mobile hardware like your camera while also giving you integration with native apps like instagram and facebook. It gives your users an experience that feels seamless. The biggest benefit to you, is that you no longer need an iOS developer or an Android developer. Rather, you can now use your web developers to help build that mobile solution your company has been looking for. I have worked alongside of former Ionic team members building enterprise level applications using the latest version of Ionic. If you're thinking of building a webapp that needs a mobile counterpart, get in touch with me today so we can discuss how Ionic will help you create the product you need.

Firebase is a niche solution that I have grown to love. While I seldom use the default Firebase solution, I often use the upgraded version known as Firestore. Firestore gives a NoSQL solution with better querying capabilities that firebase lacks. When I couple this with cloud hosting, cloud containers, and cloud functions I can create powerful and scalable applications. The best part is that firebase provides an easy deployment process. Using AngularFire, I can simplify authentication and database querying within the frontend. This permits your team to quickly build out your products and have rapid iterations between features. Talk to me today if you're interested in using firebase on your application.

Google Cloud Platform is a technology that integrates well with the other technologies I have listed. Cloud hosting makes for easy deployment and site scaling, while cloud functions can help you protect sensitive private keys to other services like payment processing APIs. Containers offer strong solutions for creating standalone apps that can be used to power multiple applications. This can be very useful when you have a service that is needed in many places at once. Cloud features are an excellent choice for breaking down complicated apps into independent pieces, and they help to reduce the amount of infrastructure your organization needs. If you're considering a cloud based solution, send me a message right now to schedule how using the cloud can benefit your app.

Node is the backbone of most Javascript based servers. It offers a versatile sandbox to build your applications on. I have traditionally used Node with an API library like ExpressJS / HapiJS to build up powerful applications. To help with code organization and server structure, I add in typescript to make clean easy to read code. This always helps to cluster my endpoints into logical groupings while breaking up the code so that files do not become unwieldy. To polish off my solutions, I like to add MongooseJS to the stack to better facilitate my preferred database of MongoDB. This combination of technologies gets your product up and running rather quickly, while still giving you easy to read / maintain code. To discuss how I can use NodeJS to benefit your project, you should reach out to me today.

MongoDB is a NoSQL solution that's great for companies with iterating data structures. Many of my favorite projects have been built upon this database as it's fast, reliable, and offers enterprise solutions. This database offers great flexibility and wonderful ease of use and it's no wonder nearly every project I have worked on in the last 5 years has used it. If you are not quite sure of your data structures and think you might need to change them in the future, MongoDB might be the right solution for you. Leverage my years of experience working with this technology on an enterprise level for clients like CNN, The Home Depot, and Cognia to help build your app. Click the 'Hire Now' button above so we can begin discussing how this database might be right for you.

Jest is a fantastic library for unit testing. Its simplicity and speed makes it superior to its counter parts -- mainly Jasmine / Karma -- so it is obviously my favorite unit testing library to use. As applications grow, it becomes harder and harder to predict how new features may create unwanted side effects. This can introduce new obscure bugs into your most recent release. To make this situation worse, complicated codebases can make pinpointing these bugs difficult. If you thought that wasn't bad enough, it can also take a significant amount of time to locate and fix these errant behaviors due to the size of the application and the inability to pinpoint the exact location of failure. With testing frameworks like Jest, we can write tests around our methods or functions and know if they may end up failing and where we are failing before our release. This helps increase the overall quality of our code, while also reducing the time it takes to find these new bugs. If you need a hand getting unit tests into place on your app, you visited the right person. I'm a firm believer in strong testing suites for nearly any app. Click the "Talk to Thomas" button above so we can tighten up the quality on your app today.

Typescript is a superset of Javascript that helps you to ensure that your code is using the proper datatypes where you would expect. Typescript is a personal favorite since it helps to keep your code clean, organized, and easy to read. Additionally, many IDEs give additional support so that you can produce short cuts to data structures. That means no more digging for hours trying to determine a full object structure or where an attribute gets added on. Instead we can know that structure from the moment of the word go, and zero in on the code that is relevant to our problems without having to become detectives. Typescript is especially great on Javascript powered server solutions where the aforementioned scenario is the most likely to occur. If you're interested in saving your project hours of troubleshooting by using Typescript, press the "Hire Me" button to begin talking about how I can use this technology to benefit your team.

Hello all, Thomas was very professional and knowledgable. He took the time to explain concepts that I didn't understand. As someone that has been in technology for 30 years, I was impressed by his skills and due diligence. If you have any issues with Angular, this is the guy you need to talk to. Thanks again for the help!

This application is my personal portfolio and demo application. Since many of my applications are under NDA or require application purchase to view, I created this website to demonstrate my abilities as a developer. The site is a PWA that takes a modern approach to development. It's solely built within the cloud and uses technologies like Angular, Firebase, GCP, Express, Contentful, and mailgun to create a rich website with sleek modern design. I have designed the landing page myself, and am currently reworking the older pages of the site for a more modern design. Please feel free to visit, poke around, and ask me all about it!

This application is the marketing and ecommerce store for Supersapiens. They create sports medicine patches to monitor the blood sugar of endurance athletes and give them real-time feedback about their performance. While the application of this technology is quite niche, Abbott pharmaceuticals has recently acquisitioned the company to produce these patches for a wider variety of medical purposes. Some of these applications include a cheap way for diabetic patients to monitor their blood sugar. The application is very modern with an Italian design firm creating many modern and cool designs. With the ample animations, it was a very challenging website to produce. From videos to animations that provide an immersive experience, there was a large amount of work in the stylization side of the side. I consider this application one of my most highly refined pieces of work and a crowning achievement in my career.
