    For most of my over 10-year career, I've written and debugged a variety of software and have solved various types of problems. At Techno-Sciences, this was primarily software which handled communication between hardware devices with different protocols, and getting them to work together as a maritime surveillance unit. With Polycom, it was software which handled communication between Polycom's DMA and external hardware components such as phones, web services, and video conferencing devices. Then, with Spectra Logic, I wrote automated test code to debug communication between Spectra's backup software and various hardware storage devices, as well as cloud storage services such as S3. Next, with RK Mechanical, I programmed software to import product and price data from various APIs and data sheets and consolidate it. After that, with Exolvo Designs Group, I am enhanced software for a search-and-rescue antenna configuration system. And now, with Versity, I've done Golang programming for a data storage analysis tool and am currently doing bats testing for an AWS S3 gateway. In addition to my current contract at Versity, I'm open to freelance work in any field I find engaging, fields where I can put software together to solve problems and improve my knowledge. Skills: * bash/bats * Golang * github-actions * REST API * React.js * Docker * AWS * SQL Server * Python * MongoDB * Java * C++

    I've been meeting business and consumer needs by building and maintaining software in small teams for nearly 20 years. Whether you’re starting a new project, fixing or enhancing an existing one, or looking to elevate your own skills, I can help you achieve the results you’re looking for. My strongest area is browser-based development, from standards-compliant HTML, JavaScript/TypeScript, and CSS to complex single-page apps built with frameworks like React and Redux. I'm also proficient with server-side languages and technology like C#, PHP, and node/deno, but I haven't done much significant with JVM languages (Java, Kotlin, Scala). In addition to serving web pages and apps, I've created and maintained APIs, built message production/processing systems (RabbitMQ, GCP PubSub), and done a fair amount of payment processing.

    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!

    As a US-based GIS expert with over a decade of specialization in spatial data, I help organizations harness geospatial intelligence to drive informed, data-backed decisions across sectors such as telecom, real estate, supply chain, and intellectual property. I love beautiful designs and deliver elegant solutions. I’m proficient in JavaScript, React.js, Next.js, Node.js, and the full AWS ecosystem—including Lambda, S3, Elastic Search, and DynamoDB. My technical skill set includes geospatial platforms like Mapbox, Google Maps API, DeckGL, combined with deep experience in full-stack web development using the React framework and NodeJS/Express. I design and develop dynamic, interactive geospatial visualizations and robust web applications that transform complex spatial datasets into intuitive, decision-driving interfaces. My broader expertise spans UI/UX, system architecture, ERP, GIS, CI/CD, and custom API development.

    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.

    Estimating: I've worked in the construction field for most of my life, specifically in the restoration business, so I know it quite well. I've been on the mitigation side, reconstruction side, and est/pm. I can write an estimate with accuracy and speed as long as all parts of the scope are known. Web Developer/Designer: Took formal training to learn the processes of web development. Both front end and back end. Comfortable working with javascript, react, python, CSS, HTML. I've always had a great eye for design and can tell when a website looks good, and functions well. Both are equally as important.
