Jordan Sitkin

Coinbase

Senior Software Engineer, Performance & Reliability

From 2017 in San Francisco, CA

I work closely with other engineers on product focused teams to help them ship scalable code. Projects include patching database drivers to meet our performance requirements, writing custom instrumentation to understand load on our backend services and creating load testing tools to help understand the capacity of quickly evolving codebases.

Kit Kraft

Senior Developer

2015-2017 in Oakland, CA

My grandparents started Kit Kraft in Studio City in 1946, and my father took over running the store when I was a kid. In 2015 I decided to join the family and help turn around a downward sales trend on the then-aging website.

I designed and developed a new site, migrating from an off-the-shelf PHP framework (X-Cart) to a custom Rails project. Since launch, nearly every aspect of the business has benefited. Together with the team in Los Angeles I helped integrate a new point of sale system and modernize outdated purchasing and inventory systems. Site revenue has increased 28%.

Technical Highlights

• Docker + Amazon ECS on AWS create a painless development and deployment story. New team members can spin up a local dev stack with a single command.
• A new custom fulfillment backend helps get orders out quickly and correctly. Integrations with our shipping providers handle postage and labels.
• Custom marketing tools help our team get the data they need and make changes to site content without developer involvement.
• System design embraces AWS services to lower operational overhead. We utilize EC2, ECS & ECR, S3, CloudFront, CloudWatch, RDS, ElastiCache, Lambda, SQS, Route 53 and SES across two regions.

Nuts.com

Tech Nut

2014-2015 in Oakland, CA

I joined nuts.com during a period of rapid growth, and on my first day started work on a brand new front end for the site. My responsibilities were wide ranging. I led efforts to refine UX, extend the brand's visual identity and establish design standards. I also designed and implemented a modern responsive front end codebase based on logicless templates and discrete components.

Highlights

• Created a library of composable AMD modules to power the front end. There are few dependencies, and no heavy front end frameworks.
• Implemented all site templates in mustache, moving display logic into a separate view layer.
• Planned, designed and illustrated visual assets – everything from vinyl wraps for delivery trucks to packaging concepts to site promos.
• Helped move a brittle deployment flow based on Chef/OpsWorks to a more robust one based on Docker and Amazon ECS.

• Designed and coded a scratchbuilt ecommerce platform with rails, deployed on Heroku.
• Optimized the stack to handle bursts of heavy traffic with aggressive caching and background job queues using memcached and redis.
• Integrated APIs for payment processing including Authorize.net, Stripe and Dwolla.
• Built a consistently threadsafe rails stack to facilitate on-demand scaling.
• Designed and implemented the entire front-end, including UI/UX design and code.

Specify

Co-Founder / CTO

2010-2014 in San Francisco, CA

• Implemented a complex one page app without a javascript framework (learned many lessons).
