From Sugauli, Bihar • B.Tech CSE @ LPU (Sep 2022 – Jun 2026) • Android Developer at Adyapan Edutech. Specialized in building clean, offline-first mobile apps with Jetpack Compose, MVVM architecture, Room Database & scalable Firebase backends.
I'm Gulshan Kumar, from Sugauli, Bihar. I am an Android & Flutter Developer at Adyapan Edutech and completed my B.Tech in CSE from Lovely Professional University (LPU) (Sep 2022 – Jun 2026).
I have strong hands-on skills in building mobile applications — from architecture design to UI implementation. I excel at translating complex requirements into clean, responsive user interfaces using Jetpack Compose and modern architectural patterns.
I build with an engineering mindset — utilizing MVVM architecture, Room Database for offline-first capabilities, WorkManager for background tasks, and Firebase for cloud backend and secure authentication. I care deeply about writing clean, maintainable, and testable code.

How I design and develop robust, industrial-grade Android applications to ensure optimal performance and user satisfaction.
Developing responsive, fluid mobile interfaces using Jetpack Compose and modern design tokens, combined with classic XML hybrid layouts for full compatibility.
Implementing reactive local caching using Room DB and standard Repository patterns. Ensures apps remain completely functional with instant data loading even without network connectivity.
Managing asynchronous cloud synchronizations and telemetry tasks cleanly using WorkManager, Foreground Services, BroadcastReceivers, and Kotlin Coroutines/Flow.
Encrypting local user preferences via EncryptedSharedPreferences and securing cloud endpoints with Firebase App Check and robust role-based firewalls.

UI components observe reactive UI state flows emitted by ViewModels. Screens only render what the state holds, ensuring zero UI glitching, state desynchronization, or memory leaks.
@Composable fun LeadScreen(viewModel: LeadViewModel = hiltViewModel()) { val uiState by viewModel.uiState.collectAsStateWithLifecycle() ... }
Interactive mobile guide published on Google Play Store that enhances the zoo visiting experience with real-time GPS navigation, detailed animal encyclopedia, interactive maps, and live event alerts.
Full-featured Android CRM application built solo from scratch for sales teams to streamline outreach with one-tap calling, follow-up scheduling, GPS attendance with selfie verification, and offline-first sync.
A comprehensive Flutter-based school management application built for students, teachers, and administrators. The app covers the complete school ecosystem — from class-wise learning content and attendance tracking to admin controls and real-time notifications. I was responsible for complete frontend & UI development.
A comprehensive Learning Management System (LMS) website built during my time at LPU. A centralized hub connecting students, teachers, and administrators to access resources, track progress, and facilitate efficient learning.
A complete Android game supporting Player vs Player and Player vs Computer modes. Implemented computer opponent decision logic to automatically select optimal moves, robust game state management to track turns and draw conditions, and real-time restart functionality.
Interact with live simulated interfaces of ZooVerse and LeadDialer to explore their features, UI screens, and offline-first workflows.
Interactive Google Maps SDK integration with custom vector markers, geofenced discovery alerts, and offline caching for seamless visitor guidance.
Promoted to Full-Time App Developer following successful internship. Leading end-to-end native Android and cross-platform Flutter application architecture, development, and Google Play production releases for business-critical mobile workflows.
Worked as an App Developer Intern, designing, building, and shipping 3+ production apps used daily by real employees and students across the enterprise ecosystem.
ACTION_CALL intent) and Room DB syncPursued Computer Science & Engineering, specializing in Native Android Development (Kotlin/Compose), Flutter, and AI/ML. Built multiple projects, solved 200+ DSA problems, and achieved Institution Rank #500 on GeeksforGeeks.
Skills and qualities that make me a strong addition to any mobile development team.
Deep hands-on knowledge of Kotlin, Jetpack Compose, MVVM, Room DB, WorkManager and the full Android SDK. I build apps that feel native, fast and reliable.
Ability to ship beautiful iOS + Android apps from one codebase using Flutter & Dart — saving time and resources without compromising quality.
Integrate Firestore, Auth, FCM, Storage, and App Check seamlessly. I can handle the complete backend of a mobile app without needing a separate backend developer.
I write scalable, maintainable code using MVVM, Repository Pattern, and Dependency Injection. Code that's easy to test, debug, and extend by any team member.
Certified in Machine Learning (DeepLearning.AI + Stanford). Can integrate ML models into mobile apps using TensorFlow Lite for intelligent features.
I pick up new technologies quickly and don't wait to be told what to do. I proactively solve problems, research solutions, and deliver results independently.
A collection of professional certifications from Coursera and NPTEL (IITs) verifying my expertise in app development, machine learning, and computer science fundamentals.
Comprehensive certification covering virtualization, cloud architecture patterns, distributed storage systems, and cloud resource scheduling policies.
3-course specialization by Andrew Ng covering Supervised ML (Regression/Classification), Advanced Learning Algorithms (Neural Networks, Decision Trees), and Unsupervised Learning (Recommenders, Reinforcement Learning).
In-depth networking course covering the five-layer TCP/IP model, routing protocols, DNS, DHCP, IPv4/IPv6 subnetting, and network security policies.
I'm open to new opportunities, collaborations, and interesting projects. Feel free to reach out!
