Building the Metaverse.
Working on a variety of stuff as a generalist
A web development and tutoring company.
Software Architect, React.js Expert, Technical Publisher
Software Architect with broad experience in hands-on coding, architecture design, helping C-suite management make good decisions, and leading teams to success. I'm also a React.js expert with open-source contributions and publications about web development.
The biggest platform for ordering food online.
Was responsible for re-building the www.10Bis.co.il website from scratch with a team of 5 people. We did it in a very short time, even though some people from the team were unfamiliar with Next.js and React.
Later, I lead the creation of several other projects while also leading the front-end guild of around 7 people.
Cloud-based software for creating animated presentations.
Team Leader / Technical Leader
Initially I started off in charge of migrating PowToon's Web App from Flash to HTML5-React-Redux, essentially re-building the site from scratch. I created the infrastructure of the project and did the core graphical-mathematical work as well.
Our team of around 8 people consisted of developers from WellDone Software and PowToon. I was responsible to tutor and train PowToon's staff in learning everything about HTML5-React-Redux.
Later, I worked on the project's CI, testing, PowerPoint plug-in, and many other side projects.
User experience tools for intelligent email and Office365/SharePoint Management.
Full-Stack Developer, Mobile Developer
In these very intense three year period, I had the opportunity to work on many of harmon.ie's products. We developed web apps, Microsoft Office Plug-ins, and several apps for Android, iOS, and Windows Phone using Cordova.
During that time, I gained a lot of experience with various APIs by creating a cross-platform aggregation software that combines information from SharePoint, SalesForce, social networks, management platforms, and e-mail.
The Open University is open to anyone who wishes to study towards a bachelor's degree, without any prerequisites or screening process.
The Open University, However, has high academic standards and its graduates are considered very competent in their fields.
B.Sc., Computer Science
Developers tend to know very little about SEO because usually we tend to focus on how the website is exposed towards users and not bots, but it’s a very beneficial thing to know. SEO is very important for most of the modern websites because higher rank = more traffic = more money.

There are numerous strategies to choose from when building modern HTML-based apps today.
You can render it on the client-side, the server, or even generate it during build time.
You need to make a choice, and tools like Gatsby, Next.js, Angular Universal, ScullyIO, and NuxtJS can help you get there.
How do you make the right choice though? Why would you choose one over the other?

One full day, over 500 participants, 3 tracks, 13 lectures, and one cloud experts panel!
Wow, we had a blast.
The software development world is developing at a tremendous pace. New technologies and platforms are abundant, and things that were brand new a year ago sometimes suddenly seem like ancient history. The software architect’s job is to figure out how to best use these technologies and platforms to his/her advantage, and that job is getting harder and harder. At Architecture Next 2020 we discussed revolutionary concepts and tools and demonstrated how they can be applied towards making your next software system a better one.
Due to Coronavirus related restrictions, this year’s conference, held for the third consecutive year, was all virtual. But as usual, was packed with great content and insightful speakers.

The Virtual DOM is roughly what we generate through the renders of React components. But React is designed in a way where we don’t usually need to care about what exactly happens as a result of these renders. This lecture aims to explain the relationships between different React elements- a concept that would help us reveal React patterns where performance might be an issue, and how to handle them.

I've recently worked a lot on performance improvement. I've read a lot of articles, and written a lot of lines of code. I've even maintained one of the most important libraries to detect performance issues (why-did-you-update), and later wrote an even better library from scratch (why-did-you-render).
My lecture will focus on how React's Virtual DOM actually works, and how to work with it efficiently when performance issues arise. We will also talk about what "performance issues" actually mean, and how to detect them.
Filmed @ Negev web developers meetup at wix offices, Beer Sheba
The Jabber panel along with Vitali Zaidman jump in and discuss how your browser cache works, what the standard is, and what you can expect when you're trying to take advantage of the performance characteristics of your users' browsers.
In this episode, the panel discusses React Performance. The panel talks about performance in general tools, concepts and priorities.
Today's show is about SEO for developers. SEO stands for search engine optimization, which helps your website appear higher on search engines.

A small but important performance fix in the early stage of react-redux migration to React hooks
why-did-you-render monkey patches React to notify you about avoidable re-renders.
(Works with React Native as well.)
Creates a function that caches the last result of arguments, by key calculated from the arguments.
A webpack loader canonizing xml files, fixing issues like unquoted attributes:
<div width=100px /> → <div width="100px"/>
A webpack plugin to list all deployed files.
This demonstration shows how to detect and resolve performance issues in React using the library Why Did You Render.
Mocking function calls within a module
Sometimes we respond to React element mounts. The first instinct is to useRef & useEffect. But It’s wrong. What you really need is often useCallback.
