Software Developer · Product Builder · Cloud & Infrastructure Enthusiast
I build practical software products and explore the engineering behind reliable, scalable applications. Currently pursuing a B.Sc. in Information & Communication Engineering at East West University, I focus on cross-platform application development, backend systems, cloud infrastructure, and cybersecurity.
Core Engineering Focus
4 PillarsSoftware Development
Crafting responsive cross-platform mobile apps and practical web products with Flutter & React.
Backend & Databases
Architecting robust data access layers, relational schemas, auth flows, and low-latency APIs.
Cloud & Infrastructure
Designing cost-efficient architectures, client-side caching strategies, Linux systems, and CI/CD.
Cybersecurity
Implementing principle-of-least-privilege access, secure secrets management, and resilient systems.
EWUmate Ecosystem
The multi-tier academic assistant platform custom-engineered for East West University students. 42 mobile screens, serverless Python microservices, and offline-first zero-wait sync.
Combinatorial Clash-Free Routine Permutations
During EWU advising rushes, students manually cross-reference 100+ page PDF catalogs trying to prevent schedule clashes. EWUmate offloads candidate courses to an Azure serverless Python solver that evaluates permutations and generates clash-free combinations with pinned professors in < 250ms.
Uses recursive combinatorial backtracking with bitmask time-interval overlap screening. Pinning a section locks the time slot and immediately prunes incompatible branches from the search tree.
Multi-Tier System Architecture
Built for zero-wait UI rendering, multi-tenant database security, and fault tolerance across hostile campus networks.
4. Cloud Compute (Azure Functions)
Serverless Python worker executing combinatorial routine algorithms, PDF parsing, and university scraping.
Scales elastically during advising rush periods. Consumes user section selections with pinned preferences, prunes conflict trees via combinatorial backtracking, and generates clash-free student timetables in milliseconds.
Selected Systems & Projects
Architected for reliability, mathematical precision, and systems integrity. Each project contains a full technical architecture case study.
ICE245 Algorithm Design Course Project (Lab 4: Greedy Algorithms & Lab 13: Mini Project). An algorithm workbench implementing invisible payload carriers, greedy distribution heuristics, and steganographic data embedding over communication signals.
Data Structures Course Project (ICE207). High-performance C++ simulation engine modeling road networks as weighted directed graphs. Features DirectionService, spatial indexing, min-heap priority queues, and P2P proposal managers to match campus commuters in real time.
Object Oriented Programming Course Project (ICE107). A lightweight JavaFX desktop companion for East West University students natively interacting with the Supabase backend. Implements strict OOP design patterns, inheritance hierarchies, and event schedule mapping.
Structured Programming Course Project (Dept. of ICE, East West University — ICE103, submitted to Lecturer K. M. Safin Kamal). A robust C-based management system to monitor student mental health with daily mood tracking, consultation recommendations, and appointment scheduling.
The standalone combinatorial routine generation engine for East West University students. Solves multi-course timing clashes, respects pinned faculty preferences, and generates optimal timetables in under 250ms.
East West University Public Study Materials, Past Questions & Notes Archive (vault.ewumate.pro.bd). 100% public access to search, browse, preview, and download study materials without login, with in-browser PDF preview and 1-click Google Drive downloads.
East West University academic cover page generator and backend microservices. Generates official EWU format cover pages (Assignment, Lab Report, Term Paper), auto-fills instructor info from course/section codes, and executes serverless PDF synthesis.
The official promotional platform for EWUMate at ewumate.pro.bd. Features responsive glassmorphic interfaces, interactive schedule previews, support documentation, and iOS PWA launcher.
Architecture & Stack
Core technologies and distributed paradigms utilized across production mobile clients, serverless compute, and resilient databases.
Languages & Core
Low-level systems programming, backend scripting, and typed full-stack architectures.
Algorithms & Graphs
Graph search heuristics, combinatorial optimization, and algorithm workbenches.
Mobile & PWA
Cross-platform mobile applications, offline-first state persistence, and native alarms.
Backend & Cloud
Serverless compute microservices, relational schemas, and sub-10ms distributed caching.
Web & Architecture
High-performance web frontends, design systems, and GPU-accelerated styling.
Desktop & Native
Standalone desktop utilities, native system installers, and cross-platform desktop UI.
Tooling & DevOps
Version control workflows, build pipelines, containerized microservices, and testing.
Design & Product
User-centered interface design, production design tokens, and developer documentation.
