I’m Newfadel (Yui Kasumi) — a developer, engineer, and problem solver with a systems mindset.
I combine expertise in software engineering, SQL databases, full stack web development, and hardware/PCB design to deliver solutions that are both precise and scalable.

My approach is disciplined: I reject shortcuts and focus on clarity, completeness, and maintainability. Code should be explicit, runnable, and long-term reliable — not fragments that leave assumptions behind.

• 🛠 SQL Expertise — Deep knowledge of database design, optimization, and query performance
• 🌐 Full Stack Development — Frontend, backend, API, and deployment with clean architecture
• 🔌 PCB & Hardware — Designing circuits and integrating software-hardware systems
• 🧩 Systematic Problem Solving — Mapping inputs, processes, and outputs with precision
• 📏 Code Discipline — Always complete, explicit, and production-ready
• 🌱 Continuous Growth — Adopting new tools and frameworks while holding on to strict standards

• Detail-Oriented — Every element, whether code or circuit, must be exact
• Structured Thinker — Always seeking the most efficient and scalable solution
• Principled Coder — Believes that clean, complete solutions outlast hacks
• Collaborator — Prefers shared clarity and explicit standards when working in teams

I see development as more than writing code or designing circuits — it’s about building systems that are robust, understandable, and future-proof.

I'm always interested in discussing new opportunities, interesting projects, or just having a friendly chat about technology.
