About Esther

Hi! I’m a passionate Back-end Developer with a strong backend expertise and a track record of building robust, scalable web and mobile solutions.

Originally from France, where I earned my Master’s Degree in Advanced Computer Science, I am now based in the most beautiful city in the world: Jerusalem. I bring efficiency, dedication, and problem-solving energy to every project I touch.

With over 3.5 years of professional experience, I spent a pivotal part of my career in an agile, close-knit company. This "all-rounder" startup environment allowed me to wear multiple hats, master the full project lifecycle, and easily adapt to any technical ecosystem.

Naturally curious and tech-savvy, I love exploring cutting-edge technologies. I heavily leverage AI-assisted coding to optimize my workflows, write cleaner code, and deliver high-quality results faster for my clients.

Whether you need a brand-new platform or a modern upgrade, I am available to build:

  • Websites & E-Commerce: From showcase sites with custom booking plugins to high-traffic ticketing systems
  • Mobile Applications: Cross-platform and native apps tailored for seamless user experiences.
  • Custom Back-Office & CRMs: Robust REST APIs, secure database architectures, and central system management.
