};About Me
Software Engineer passionate about engineering resilient backends, AI integration, and algorithmic excellence.
I am currently working as a Software Engineer Intern at Samsung R&D Institute Bangladesh, following my backend development tenure at the ICT Cell of Jatiya Kabi Kazi Nazrul Islam University. My engineering journey blends rigorous academic study in Computer Science & Engineering with hands-on experience creating resilient production architectures used by thousands of stakeholders.
At Samsung R&D, I spearhead performance optimization across backend logging pipelines and Android builds—reducing database storage overhead by 30–40% and cutting Android APK sizes by 50–60%. I work with gRPC communication protocols and debug sensor ingestion pipelines with deep root-cause analysis.
Competitive programming is the bedrock of my analytical thinking. With over 1,700+ problems solved, a peak rating of 1420+ (Specialist) on Codeforces, and as a 2024 & 2025 ICPC Dhaka Regionalist, I bring mathematical rigor, clean algorithmic structures, and fast debugging to every system I engineer.
