Hey there, My name is Jonathan and I offer services as a fractional CTO, full-stack developer, and personal privacy consultant. Let me tell you a little bit about how I got here... I've been working with the web stack since I was young but started out my career about 12 years ago when I started working with WordPress and front-end development. I was able to use those skills to land myself a job at a Silicon Valley tech startup as a front-end engineer. I worked across the web stack using the EmberJS and Rails frameworks. Eventually, I was offered a role as the CTO /technical co-founder of a Real Estate Tech startup. I jumped at the opportunity. It was there that I developed skills as a backend developer, infrastructure architect, and as well as a leader. I built our SAAS application from the ground up and worked across the stack implementing agile methodologies and business processes across multiple domains. We grew that company over the course of 4 years and successfully exited in 2021. After my exit, I stayed with the company leading development and product management. We grew the team from 2 developers to 7 and worked to scale the product and infrastructure. My work included scoping technical projects, leading daily standups, code reviews, creating and managing tickets, and holding interviews for both product and development. Currently, I work as a Fractional CTO. I use the skills I've learned to help bolster teams with a seasoned software development mind. My skills range from infrastructure to full-stack development, building development teams, leading a development team from the product or dev side. I also dive deep into the business side: setting up processes, implement best practices, reducing costs, and more. I specialize in taking products from 0 to 1 or idea to inception as well as jumping in to take over projects stuck in development hell in order to get them back on track so that they deliver on time and on budget.Backend Rest API

I specialize in creating highly modular applications that are built to meet minimum viable product requirements while being open to later extension. I also believe that you can move fast without breaking things or accumulating massive technical debt. I have more than a decade of experience in both web development and business automation. I am flexible and comfortable working anywhere in the stack, though I very much shine in backend development. I have experience in: - Producing API driven websites in Node, with strong security requirements. - Building blazing fast, composable low-level applications in Rust. - Bash scripting and automation. - Administrating and provisioning Linux servers, typically through AWS. - Managing databases, including Postgres, Neo4j, MySQL, RethinkDB, CouchDB, and others. - Building inventory systems and integrations between incompatible APIs. - Producing both native Android applications and cross-platform via Cordova. - Managing e-commerce sites and storefronts.Backend Rest API
