I have three years of experience managing backend, web, mobile and firmware developers in the IoT industry, leading the architecture and participating hands-on in every aspect of the development process.

For the past 3 years I have deployed a large number of web apps and micro-services to Amazon EC2 for production and development environments.
I have also used CodePipeline, and CodeDeploy with Jenkins and GitHub integration for continuous development and continuous integration.

Extensive experience in setting up microservice environments on AWS including Kubernetes, Docker, CI/CD.

I have been using Docker as my go to container technology on all of my projects for the past few years.

I use microservice architecture on the backend on all of my projects.
I develop the services mainly in Java (Spring Boot) and Node and use Kubernetes for orchestration, usually on AWS.

פיתחתי מספר אפליקציות web כולל אתרים וממשקי ניהול לאפליקציות מובייל
תוך שימוש במגוון של טכנולוגיות כגון:
- JQuery
- JQuery UI
- HTML5 + CSS3
- Bootstrap

I have developed and participated in the development of complex enterprise systems using Spring and Spring Boot.
I also have some minor experience with Weblogic and Websphere.

ניסיון רב ומגוון ב-Java כולל מימוש פרוטוקולי תקשורת,
פיתוח אנדרואיד, פיתוח צד שרת כולל Spring.

ניסיון עשיר ומגוון בפיתוח בחברות גדולות, סטרטאפים וכעצמאי כולל:
- Java
- ++C
- C
- Android
- Node.js
- Javascript
- SQL + NoSQL

I have been using MySQL in for a long time for back-end systems for web and mobile apps.
I use it whenever a relational database is the right choice.

Hands-on experience with NoSQL technologies including MongoDB and Redis, as well as implementation of machine-learning Algorithms using Apache Spark over Hadoop.

פיתחתי מספר אפליקציות מורכבות במגוון של תחומים כולל mobile security, תמיכה טכנית, בנקאות, חדשות ועוד.
את האפליקציות פיתחתי לבד כולל ארכיטקטורה, צד שרת, עיצוב וכו'.
הניסיון שלי כולל מגוון רחב מאוד של Android APIs.

בניתי את ה mobile backend למספר אפליקציות אנדרואיד ב Node.js עם MongoDB

Most of the systems that I have developed over the past few years use MongoDB as their primary database.
I have deep knowledge and understanding of queries, aggregations, indexing and performance considerations.

I have developed many web application using Java or Node.JS for the server-side, and Angular.JS for the client side.
I typically use MongoDB or MySQL as a primary database, depending on the requirements.

Significant hands-on experience with NoSQL technologies, mainly MongoDB and Redis.

I have a vast experience in both developing and accessing REST and SOAP APIs in both Java (Spring) and Node.JS.
This includes developing RESTful web services for Angular.JS and Android apps, and accessing 3rd party APIs such as Google APIs and SMS gateways.

As part of my experience as a full-stack web developer I have worked extensively on front-end development using React + TypeScript + Redux.

I have a significant back-end development experience in Java (Spring Boot) and Node (Express), mostly in microservices environments (Docker, Kubernetes).
