🏆 Codeforces Candidate Master (Peak Rating: 1917) | 1x ACPC Regional Advancer | 4x SCPC Participant
Hello! I'm Ghifar Haidar, a Full-Stack Software Engineer specializing in event-driven architectures, distributed systems, and modern fullstack development across .NET (ASP.NET Core, React), Laravel, Spring Boot, and Node.js.
Backed by an elite competitive programming background (1,650+ problems solved), I bridge deep algorithmic optimization with production-grade system architecture, high-throughput caching, and localized UI/UX designs.
- 🏆 Competitive Programming Highlight: 4x Syrian Collegiate Programming Contest (SCPC) Participant and 1x Arab Collegiate Programming Contest (ACPC) Advancer; 2x Gold Medalist at local collegiate qualifiers (2024, 2025); mentored 40+ students in advanced algorithms and graph theory.
- 🔭 Currently building scalable event-driven systems using .NET Aspire, Redis Pub/Sub, and React 19.
- 🌱 Expanding knowledge in distributed caching, time-series data pipelines, and cloud-native architectures.
- 💡 Passionate about query optimization, low-latency API delivery, and solving complex algorithmic challenges.
📌 Note: My startup fullstack and backend projects are developed under non-disclosure agreements (NDA) and reside in private proprietary repositories. Below is a summary of my production impact.
