I'm Oussama, a Software Engineer. I genuinely enjoy the mechanics of code, from low-level C/C++ architecture up to full-stack web development. I have spent years building custom automation tools, web scrapers, web extensions, and complex web applications, always focusing on performance and logic.
I'm also an active CTF player and problem solver, which means I have a security-first mindset. I love deep diving into code, networks, and hex dumps to hunt down bugs that others miss.
Whether you have a tech problem, a security concern, or a new project idea, send me a message.
FAQ
What kind of custom Browser Extensions can you build?
I can build almost any tool that runs in a browser. My expertise includes Web Scraping extensions to extract data, Automation tools to speed up repetitive tasks (like form filling), SaaS products for startups, and custom Data Entry dashboards. Whether it is for Google Chrome, Firefox etc...
Is the extension secure? Do I get the source code?
Yes. I develop with a security-first mindset. Unless your project specifically requires an external database, the automation logic runs 100% locally on your machine to protect your privacy. And yes, you receive the full Source Code upon delivery so you maintain full ownership.
What happens if the website updates and the scraper stops working?
Websites change frequently. I write robust selectors to prevent this, but if a target site updates its layout shortly after delivery, I provide support to fix the scraper or automation script to ensure it keeps running smoothly.
Do you use the latest Manifest V3 standard?
Absolutely. Google is phasing out the old V2. I build all new Chrome Extensions using the latest Manifest V3 standard, ensuring your tool is future-proof, secure, and ready for publication on the Chrome Web Store if needed.
