My experience spans developing web and mobile applications, collaborating closely with diverse stakeholders, and thriving in early-stage startups and R&D "skunkworks" projects. With a solid software engineering background, my passion lies in embracing AI-human collaboration – where creativity, empathy, and intuition are valued just as much as technology.

Together, we can unlock the immense potential of humans and machines working harmoniously, driving innovation and success.

    Hello and thank you for reading my profile! My name is Henry and I am at your service. I have been working with Ruby on Rails for four years now. I still love coding with Rails every day. I consider myself a polymath of many computer techonologies, with a strong focus on Web Development, and a strong focus on Rails within Web Development. I choose to focus on Rails because I find that its developers make careful and considerate choices about low level code implementations so that as an application developer I can focus on delivering high level features. Whether you need your current app debugged or you have an idea that you want to design and deploy, I will give you my honest opinion on what your app needs and how long it's likely to take. I have a lot of web development skills: 1. Modeling and implementing your business logic with ActiveRecord and MySQL or Postgres. 2. Deploying to Heroku, using Heroku plugins for SQL, SendGrid, asynchronous tasks and scheduled tasks. 3. Configuring DNS. 4. HTTP protocol examination and debugging including Cross-Origin Resource Sharing and many other headers. 5. Frontend Coding, I especially like StimulusJS, Turbo, and Hotwire as well. 6. Keeping users engaged with push notification technology. 7. Familiarity with Docker. 8. Familiarity with Ansible. 9. Familiarity with Ubuntu Server. I'm looking forwards to joining your project and making a strong contribution. Thank you very much.

    As a programmer, I will work till a project’s ideas and goals are clear. Working with a team is great, and I am comfortable with working solo. My overall objective is to not only get the job done, but to do it well. I graduated from the University of California, Merced with a Bachelor of Science in Computer Science and Engineering. Pursuing a degree made me aware of the vast field of Computer Science. I would like to learn as much as I can from the many subjects of software development. All my personal projects are created with passion. They begin from a small idea that I eventually expand upon. Those projects evolve from a desire which is to truly understand how they work from beginning to end. My experience stems from education and personal projects. I am mainly experienced in C/C++, but I can adapt to other languages. I would love to take my education and learn to apply it to an opportunity to expand my ability as a software developer.

    I'm a versatile web/mobile super stack developer and DevOps. For example, in the morning I can fix a bug with the Angular web app. In the afternoon I can get my hands dirty adding a new feature to the PHP/Symfony server-side application and deploy it using Docker through GitLab CI/CD. And then in the evening, I can work on the corporate new mobile application which is launching on iOS and Android in 2 weeks time. I started my career as a developer in 2007. I use Angular + Symfony since 2012 and PHP since 2008.
