Project details
Is a broken script, server error, or frustrating bug disrupting your software or web app? I deliver fast, dependable, and clean code corrections to get your system back on track.
With years of professional software development experience, I specialize in root-cause analysis, deep-code debugging, and performance optimization across multiple languages and frameworks. I don't just apply temporary "band-aid" patches—I locate the underlying flaw and refactor the code so the issue stays fixed.
What I Can Fix:
• Frontend UI layout breaks, responsiveness, and JavaScript crashes
• Backend logic bugs, API integration failures, and database queries
• Server errors (500, 404, CORS errors, authentication failures)
• Performance bottlenecks, memory leaks, and slow load times
Why Choose My Services?
Having worked on enterprise-grade software and complex applications, I understand production stability. I follow clean code practices, maintain strict data security, and ensure zero disruption to your existing features.

Bilal delivered my project just as promised, on time and just the way I envisioned.
He was very patient with all the changes and small details I requested, and worked efficiently until I was satisfied with the final result. I will definitely work with him on any future project that entitles his area of expertise.
Thank you Bilal

Web Developer Needed — Hostinger Experience Required (Author Website)
It was a pleasure working with Bilal. He understood I needed a new website from scratch. I had guidelines and ideas, and he delivered quickly. I had documents, pictures, links, and multiple pages. He was able to move, attach, and change everything I requested. My computer skills and understanding are very limited, and he was able to work with me and figure out what I needed before I did!. The project took under 2 weeks, and the cost was very reasonable. I will hire him again when that time comes.

Job Success
Algiers, Algeria - 8:34 pm local time
I’m an experienced Software Engineer (with diploma) and Developer (not a vibe coder ! i understand and i can do everything) specializing in Python, Java, Javascript, Typescript, and modern Web technologies (Angular, Spring Boot, Node.js, Flask, Wordpress, Bootstrap, Next.js, Nuxt.js, Electron.js), and I also provide tutoring and mentoring in programming and computer science topics.
I hold a strong Computer Science and Systems Engineering background, with solid experience in software development, backend & frontend engineering, system design, machine learning (AI, ML, DL, Agents) and applied problem-solving. I enjoy tackling non-standard and real-world problems, covering application design, algorithmic thinking, system architecture, and production-ready implementations, from initial analysis to clean, documented, and maintainable code. I regularly work on full-stack engineering problems, including:
- Coding,
- Documentation,
- Manual Creation,
- Scientific & Technical Writing,
- Tutoring,
I have hands-on experience with a wide range of technologies and tools, including Python, Java, C, JavaScript, TypeScript, HTML, CSS, SQL, and frameworks such as Spring Boot, Node.js, Flask, Electron, and Angular.
I also work with relational databases (PostgreSQL, MySQL, SQL Server), and modern DevOps & infrastructure tools like Git, Docker, Jenkins, Ansible, Jira, as well as Linux environments and networking solutions (Nginx, HAProxy, DNS, virtualization).
I’m comfortable learning and adapting to new technologies quickly, and my broad technical foundation allows me to switch tools and frameworks efficiently to best fit project requirements.
Why hiring me ? because i provide a high quality job and get the job done real quick !
