    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.

    Most of my professional experience is in SQL development with American Express. The project lasted two years and my task was to convert all of our TeraData scripts and stored procedures into Hive on an AWS environment for LARGE amount of data processing and reporting to the regulatory bodies of Mexico, France, Italy and The Netherlands. I created a self-contained Python package to neatly convert all of the newly-generated Hive data into XML for each jurisdiction. In addition, a lot of my development experience is in PHP, JavaScript, building reactive SQL-database driven web applications for the marijuana industry in Colorado. I also have experience administrating many different deployment configurations for enterprise level customers. Most of my experience is in IBM z/OS Mainframe, Windows Server 2019, and RHEL. Further, the amount of projects located on my Github show my versatility in development technologies. I have also written technical documentation and developed software for IBM, Trimble Geospatial, 421Hemp, and Apollo Decentralized Asset Exchange. This shows my ability to work with both huge, enterprise level customers as well as small 1-5 person startups with the same degree of finesse and skill. The experience in highly regulated industries I possess gives me a keen focus on tasks where the level of attention-to-detail is paramount, and as an added bonus my OCD prevents me from leaving any task unfinished or subpar.
