Eduardo Ochoa

Senior Data Engineer

Eduardo is a former physics researcher turned Data Scientist and Data Engineer. He loves complex systems, but maybe even more to make complex things simple. Somehow more attached to Haarlem than to Amsterdam, he has also been bitten recently by the Zeta Alpha running craze, and has successfully completed the Dam tot Dam loop. Sometime he looks sentimental when Mexican food is discussed.

Careers

We are looking to grow the team with talented and fun NLP researchers, data and software engineers (both front end and back end), as well as entrepreneurial sales and marketing leads. We're not actively recruiting right now. If you are interested in joining our ambitious mission at some point in the future, please send your CV.  

 

We regularly have positions for::

  • Is there a free version of Zeta Alpha?
    Yes, there are two free versions of Zeta Alpha: Limited access plan Our basic Visitor plan is designed for individuals to make a first acquaintance with the platform’s functionality. However, you’ll be limited to 100 searches per month and, because the plan doesn’t involve creating a personal account, you won’t be able to use any of the personal productivity tools like tagging, note-taking, and reading lists. Students and academics If you are a full time student or an academic researcher, you are eligible for a free version of our Researcher plan. This allows you to enjoy unlimited discovery and all the personal productivity tools included in our Personal Assistant plan and completely free of charge.
  • How is Zeta Alpha different from vector databases and RAG with Langchain?
    In some sense you can see Zeta Alpha as a fully hosted vector database, with integrated LLM bindings and RAG, preconfigured workflows, a user friendly UX, and connectors for the popular apps. But it is so much more. Where LLMs have made prototyping easy, safe and secure deployment to production in the corporate IT environment requires much more sophistication. Zeta Alpha's expertise and know-how will make sure that you quickly get the productivity solution that you need from AI rather than an endless experimentation and prototyping cycle.
  • How do I get started?
    By default, you can always access and explore the free, Open Access version of Zeta Alpha's platform. To apply for a free 30-day trial of the Personal Assistant version or a free student account, please fill in the registration form and within 24h we'll reach out to you with your account credentials.
  • Will I be charged once I start a trial?
    Absolutely not. We do not ask for your payment details prior to the trial and will only invite you to make a payment when you decide to use Zeta Alpha after you’ve completed your evaluation. Your free trial is valid for 30 days.
  • How is Zeta Alpha different from free tools like Zotero or Semantic Scholar?
    You can think of Zeta Alpha as a one-stop solution for the variety of research tasks that you would normally have to spread across several of such specialized tools. Household names like Zotero or Semantic Scholar are doing a great job in their respective fields, but no solution currently on the market is able to cover the entirety of the research process to the extent and degree of accuracy that Zeta Alpha does. In other words, we stand by our promise to provide individuals and enterprises with a smarter way to discover and organize knowledge. With AI-powered search and powerful recommendations, timely personalized updates, personal productivity and collaboration features, and possibilities for indexing even enterprise content all in one place, research workflow has never been simpler. And if remember that if it's free, who is the product?
  • I am a student/academic researcher.
    If you are a student or an academic researcher affiliated with an accredited institution, you are eligible for a free version of our Personal Research Assistant plan. Please register with the email address provided by your educational institution to confirm your eligibility or send a proof of registration as a student status to support@zeta-alpha.com.
  • Can I export my data?
    Yes, we support data export of your documents, tags, and notes in multiple data formats.
