TL;DR
Entrepreneur and a runner who loves to build companies, developers and applications.
Ido has been working in technology since 1994 and is currently the Co-Founder and CTO of EspressoLabs.
From 2020 to 2022, he was a Senior Manager at Facebook, where he led the Rooms Foundation teams, driving engineering productivity and operational excellence. Before that, from 2018 to 2020, he served as VP of Technology at JFrog, where he connected business and technology by leading the partners’ engineering and IoT teams.
Earlier in his career, Ido was Director of Engineering at Netflix, spearheading efforts to improve product quality and testing. He also served as the Lead Developer Advocate at Google, where he played a key role in shaping the Google Assistant platform. Prior to that, he was the Co-Founder and CTO of High Gear Media, which was later acquired by Internet Brands.
In addition to his work in tech, Ido co-founded ApicaGreen, a U.S.-based long-short equity hedge fund that leveraged advanced search technologies for investment insights.
Ido holds a B.Sc. in Computer Science with a focus on networks and algorithms, and an M.Sc. in Business Administration (Magna Cum Laude), from Tel Aviv University.
Psst… His book “Web Workers – Multithreaded Programs in JavaScript” can help you sleep better!
A bit more?
Here is some of the fields I’m curious about:
- Startups – helping entrepreneurs with a course I did with Udacity or “Zen of Monetization” series on youtube.
- OpenWeb technologies / hacking web apps and another course on optimizing web forms.
- ChromeOS – Which I had the pleasure to be the first developer advocate for it.
- Mobile development
- HTML5 (e.g. WebWorkers, web databases, indexedDB )
- JavaScript
- Data mining and problems with ‘Big Data’ (e.g. Hacking around Yahoo finance API)
- Design/Amazing UIs
- Java and some PHP
What I love doing in my free time?
- Ironman(s)
- Cycling (From Mountain biking to Road to Gravel)
- Running – “Where the mind is willing, the body will follow”.
- Snowboarding
- Orienteering
- For more around the social channels: @greenido or LinkedIn

Life – lots of challenges come with lots of narrow paths to cross.


Thank you for this post:

Thanks in advance!!

Jason – I guess you refer to this post:
https://greenido.wordpress.com/2009/12/22/yahoo-finance-hidden-api/
so it would be better to put the question over there next time – so other reader could find it.
Any way, if you check: http://finance.yahoo.com/q?s=^N225 it will work and give you a page with data. Moreover, on historic data just use something like this format:
http://finance.yahoo.com/q/hp?s=N225&a=01&b=19&c=2010&d=01&e=19&f=2010&g=d
Good luck.
Hello Ido, I also have a question about your Yahoo hidden API page. Comments are closed on that page and so I am posting here.
I realize that it has been a long time since you posted that blog, but I was wondering about your SQL statements at the bottom of the post.
Were you implying supplying the SQL statements directly to Yahoo (in some sort of YQL REST request) or were you using some local DB that you had imported the downloaded CSV to?
Thanks
Paul.
Hey Paul,
No worries. The comments on posts are closed after 90 days to prevent spam.
As for your question. You can do both! If you wish to ‘test’ the API try something online with YQL console on the other hand, you can run this on your local database (or downloaded CSV).
Good luck!
Kind of interested in how your wife disagrees with 90% of your Yahoo Finance API post. ;p
Thanks for making it though.
Thanks and New Suggestion for your “Design” Page
Hi Ido,
First off, I wanted to say thank you for putting together the “Design” page on your site (https://greenido.wordpress.com/category/design/). There are some really useful links/resources on there.
Also, there’s a guide by SuperSummary called the “Free eBook Download Guide” (http://www.supersummary.com/ebook-download-guide/) that I thought your visitors would find helpful. Perhaps it would be worth adding it to your list of resources? Let me know what you think.
In any case, hopefully I’m not bothering you. Have a great day!
Best,
Colleen
