招聘 principal / staff 自由职业 Ruby on Rails 开发者

I've been developing software for 30 years, and I have a preference for rails due to how productive it makes me. I'm not much of a fan of the hotwire story within Rails, but mostly work with typescript on react. I'm fluent with SQL and use that to refactor poorly performing queries

I partner with non technical founders and business leaders. Together, we are building systems that solve today's problems, I am a 3x inc 500/5000 cofounder. Ive built distribution systems, technology platforms & teams, raised capital, and helped scale NYC based startups from 0 to 100. I technically cofounded a high growth company and scaled it for 7 years. I am a programmer, but the experience has also made me a strong operator, technical recruiter, trainer and executive. Seed -> Series B. I enjoy technical greenfield projects as well as taking a company through a new stage of growth. If you are looking for a CTO, technical advisor, Fractional CTO, CTO-as-a-service, or full time technical cofounder... or even COO we should talk. Many technical people do not have a business mind, they push towards expensive solutions and complexity. I love service leadership, lean startup, rails, pragmatism and simplicity. https://www.linkedin.com/in/danmorena/

I protect you from common pitfalls and ensure that what is built meets high-quality standards. As a result, you no longer have to worry about software and you can focus on what you are good at.

Building software for over a decade. Mostly with Rails, sometimes without. Interested in working with early stage startups or small tech-enabled businesses.

I am a software engineer, programming mentor, and tech intrapreneur. I specialize in building elegant and functional web solutions, primarily using Ruby on Rails. I've spent the last 10 years helping tech companies make the world a better place. In addition to lead entire projects from conception to shipping, I've demonstrated excellent communication skills. Through years of experience, I've engaged in articulate discussions, both written and verbal, with fellow developers, project collaborators, and stakeholders. My track record includes skillfully presenting complex technical concepts, contributing to detailed technical documentation, and fostering clear communication channels crucial for streamlined collaboration in software development projects. I have also showcased robust leadership skills by overseeing and managing a team of fellow software developers, steering daily operations within the technical domain. My experience extends to offering guidance and support to team members, establishing performance standards, delivering constructive feedback, and adeptly addressing challenges as they emerge. Additionally, I have taken an active role in mentoring junior developers and nurturing aspiring talents within the software development field. Looking forward to hearing from you!

With more than 10 years of experience in Ruby and Ruby on Rails, I have a track record of delivering high-quality solutions that meet both functional and design requirements. Throughout my career, I have collaborated closely with product managers and UI/UX designers to scope, design, and implement complex projects. I have also worked with both back end and front end technologies, including React with TypeScript. In addition, I have some experience with a variety of other programming languages, including Go, Elixir, C++, Haskell, Python, and Java, as well as developing my own toy programming languages and DSLs. As a passionate learner, I am always looking for opportunities to work with like-minded people and build the best software possible. During my PhD, I worked on the open-source project Bohrium, which allows for automatic parallelization of NumPy and Ruby code written in C++. Additionally, my implementation of a CSP framework for Ruby benchmarked better than the Python implementation at the time. I am comfortable working remotely and believe that effective communication is key to successful collaboration. When I am not at my computer, I enjoy geocaching, playing board games, and cooking. Jokingly, I have made stickers for my own jam brand. I am committed to becoming the best version of myself and would welcome the opportunity to bring my skills and enthusiasm to your team.

I am a huge fan of Rails, and have over 18 years experience using it. I appreciate clean, easy to read and easy to understand code. I have worked on many different projects from Rails 1-7, in every stage of development from greenfield to startup to legacy projects. I am a big fan of the recent Hotwire additions to Rails, and have worked on a number of projects using Turbo and StimulusJS. I am a full stack developer, but prefer to follow Rails standards and keep Javascript code minimal to maximize productivity. I am a strong problem solver and excel at designing systems and solving bugs. I really like to collaborate and create the best product possible.

Got my start in Java almost 20 years ago, then moved to PHP before finding home in Ruby and Rails. There's no other stack quite like it and I'm content here. Passionate about refactoring and improving the quality of existing code. RSpec is my jam because it's expressive DSL is easy to read and understand. I don't believe that strict adherence to "design patterns" is always necessarily the best option, especially when adopting those patterns require breaking established conventions. I prefer monoliths to microservices and server-side rendering to SPAs. I like to keep things simple. I like to stick to what works. Containerized apps are fun, but there's just nothing quite like a simple bundle check && bin/dev on your desktop to get you up and running. I've worked in AgTech, FinTech, RegTech, and GovTech-adjacent. AgTech was probably my favorite so far. There were so many new and interesting challenges to tackle in that industry. It was a low-pressure, low-stakes environment where exploration was what the journey was all about.
