Hi, my name is Nathan, and I'm a software engineer specializing in mobile application development. I have my Master's in Software Development from Boston University, focusing on front-end frameworks and user interfaces. My experience ranges from R&D consulting to enterprise mobile applications. I am on Upwork because I am passionate about helping entrepreneurs take their idea from napkin notes to App Store. I structure projects around an 8 week development cycle for deployment to both the App Store and Google Play. React Native makes this possible with its write once, deploy everywhere approach. Below is a recommended 8 week timeline for a simple complexity app*: Week 1: Kick-off meeting and determining requirements Week 2: Wireframing and design Weeks 3 - 6: App development Week 7: Beta version testing WEek 8: Deployment *Applications range in complexity and customization. While the above is the goal for a simple complexity app (i.e., clone of existing concept, packaged elements, etc.), a more custom app will follow a different delivery schedule. I look forward to hearing your big idea!

I'm a web and mobile full stack engineer with nearly 20 years of professional experience (that's a lot of coffee, code, and new technologies!). I've led teams at startups in Seattle, Denver, and DC, developed custom apps for mission-driven non-profits, and consulted on dozens of projects with amazing clients around the world. Whether you have a full-formed project or have just started sketching out ideas on a napkin, I would love to hear about your vision and help you bring it to reality. - Software Architect: I can work with you to design a custom integration of web & mobile front-end, backend, data layer, and cloud services to create quickly and affordably- then scale up when you grow. - Web & Mobile application development: I develop in Typescript, React, React Native, and Node.js nearly every day, am well-versed in serverside languages like Golang, Python, and PHP, and have experience with too many frameworks, libraries & stacks to list them all here. Feel free to ask me! - Database design and development: Working with data is hard, but I have been working with relational (MySQL), no-sql (Mongodb), and graph (GraphQL) databases from the beginning of my career & can navigate the benefits and tradeoffs of each approach. - Cloud Services: Everything is "in the cloud" these days, and the possibilities are endless (and very confusing). I'm experienced in both AWS and Google Cloud solutions (Lambda, SQS, SNS, S3, API Gateway, more) and integrating with third-party SSAS providers. Rather than chasing trends, I can help you leverage the right technologies to save money and adapt quickly.
