    Experienced CTO, software developer and architect with a demonstrated history of architecting and deploying fullstack Ruby on Rails (RoR) software, including LMS and SaaS products that have dedicated APIs for native clients consumed at scale. I’ve been at it since Rails 3 and personally migrated apps from Rails 4 to 7. Rails performance — faster than 300ms for a fullstack response from server; less than 1s to paint clientside — is a passion of mine, as is building software that works and satisfies constraints. If you want software that is performant while accomplishing business goals — I’m probably a good choice. If you’re looking for websockets (the Hotwired stack, mostly in RoR), background jobs (Redis / Sidekiq) help with frontend JavaScript (yes, I spent a few years working in React) or more general help designing web products that accomplish your broader goals (e.g., you want your pages to load faster; I’d help you make some of your content load asynchronously to do that). A second skillset I have relates specifically to analytics. I have considerable experience building out data tracking with various accompanying metrics and dashboards in Ruby on Rails, but I also have considerable experience with data analysis (R; Python; PyTorch; PySpark) and familiarity with with bigger data tooling and analytics (e.g., Hadoop; Pig; Spark; DataBricks; Snowflake) and specialized reinforcement learning (RLlib). Re: deployment — I usually deploy on Heroku because I have a standard Continuous Integration (CI) / Continuous Deployment (CD) playbook. That said, I have deployed software in AWS and run super intense compute processes in Azure and Google Cloud Platform (GCP). So while I focus on shipping software that works, you can expect all code I oversee to come with appropriate tests. And finally, concerning data structures and databases for production applications ... I don’t do NoSqL — I just think it’s never the right choice. Any standard relational database — e.g., PostgreSQL (best), MySQL (acceptable) — is fine. I’ve written a bunch of raw SQL — from custom procs and functions to standard INSERT commands and used a variety of add-on modules for natural language features, UUID generation, etc. And yes, I’ve migrated and updated countless databases, and I would be happy to tag which indices your database should add or remove for performance. If you want to shard your database or created read-only versions for performance, I’m happy to help you develop that strategy.
