招聘 principal / staff Ruby on Rails 开发者

Experienced Software Architect with a demonstrated history of working in the Energy and Advertising industry. Skilled in Ruby on Rails, fluent in Dutch and English. Strong research professional with a Master of Science (MSc) in Systems Engineering, Policy Analysis and Management from Delft University of Technology with a focus on Sustainable Energy.

Senior engineer with experience in both greenfield and legacy codebases. I believe that developer happiness and productivity are doubly linked and strive to optimize for both. I'm at my best when I can take ownership of high-stakes features and work with business units to understand the technical and business tradeoffs. Collaborative, no-ego teams are my favorite to foster. Most recently I've been working in the fintech industry on a legacy monolith application with Hotwire and ViewComponents. I've worked successfully with both US and overseas development teams and enjoy providing a multiplicative effect on my colleagues.

In the mid 90s, my mom's HP Pavilion was struck by lightning. Luckily, I accidentally saved a few Dragonball Z websites. Back then, you could view the source code of almost any website and copy everything there to recreate them through your browser. This is what led me to my love for web development. Hi, I'm Chris. I've been in web development professionally for over a decade. Those saved websites opened up a door into a world of problem-solving that I absolutely fell in love with. I've built everything from real-time user tracking to a key inventory management system to an events timeline to countless APIs and integrations, and somewhere in between all of those features, I found a knack for UX and UI.

I've been making software since I was a kid. I enjoy designing solutions to complex problems and building abstraction layers that make difficult problems more comprehensible. I've led teams of developers, and I've been a Director of Engineering responsible for a team building a hardware and software product. I've been a Technical Cofounder of a startup building a mobile app. I excel at communication with technical and non-technical stakeholders. In the Ruby ecosystem, I've done a lot to build developer happiness for my teams. I've upgraded Rails and Ruby in many legacy projects. On the frontend I've build iOS apps in Swift and React apps in Typescript. On the API layer I've worked a lot with GraphQL in addition to classic REST where I cut my teeth.

Senior Rails developer with generalist skillset. I've been developing Rails applications since the weekend of the first public release of Rails and am the author of 2 Ruby on Rails books. I prefer to work in small teams where I can be involved in all aspects of the application development process and have rapidly created entire applications for both small venture-backed companies and multinationals alike. Have worked as CTO at two startups, building development teams and designing the architecture for the platforms. Rails is my preferred framework, but I also develop applications in Elixir Phoenix with LiveView. While most project I have worked on have been built from-scratch, I have worked on large-scale projects built with Bullet Train and Jumpstart Pro.

With over 10 years of experience in the tech industry, my core competencies lie in developing scalable solutions and leading technical projects, exemplified in my previous role at Amazon. During my tenure at Amazon, our team developed a distributed healthcare service that significantly enhances prescription acquisition. My mission is to leverage technology to streamline healthcare processes, making them more accessible and efficient. I have experience working in both a startup and a corporation. PillPack by Amazon Pharmacy ● Led multiple projects for a team of 7-8 engineers working on microservices, written in Ruby on Rails to a workflow engine written using Camunda, all built on AWS cloud infrastructure. ● Initiated and managed a project to unify several platforms that pharmacy agents use into one core service, simplifying the number of tools from nine to five. ● Oversaw a project to implement a specialized process for Amazon Pharmacy after Amazon's acquisition of PillPack, including building a Camunda workflow engine. ● Built a new distributed and scalable service that manages the process of acquiring prescriptions from healthcare providers and other pharmacies, including a CI/CD pipeline in AWS. ● Created an integration test suite of own initiative for the system, which is being used extensively during beta testing as evidence for production.

I love helping people leverage the power of data and software. I've had the privilege of doing so in various roles for over 20 years. My specialty is working with stakeholders to develop extensible scheduling, workflow, and form systems. I also love teaching and mentoring. I'm available for freelance or contract work. Hard problems with no clear cut solution are the most interesting to me. I may also be able to help you get projects started, complete stalled projects, and coach teams on things like system design, and dealing with the technical challenges around modeling sparsely structured data (especially in healthcare and clinical research).
