About Me

Hi, I'm Kshitiz, a Mobile Engineer with hands-on experience building cross-platform consumer apps in Kotlin Multiplatform / Compose Multiplatform, alongside native Android development with Jetpack Compose.

I have a strong focus on Clean Architecture, offline-first design, and integrating client-side intelligence into mobile experiences. From shared UI modules to on-device inference, I enjoy transforming ideas into functional cross-platform products.

My experience includes:

Kotlin Multiplatform / Compose Multiplatform
Clean Architecture & MVVM
Offline-First & Repository Pattern
On-Device AI / RAG Systems
Android SDK & Jetpack Compose
Backend Integration (Supabase, Spring Boot)
API Development & Integration
Database Design & Management

I focus on writing clean, maintainable code and building applications that are fast, secure, and scalable across Android, iOS, and Desktop targets with shared business logic.

When I'm not coding, I enjoy exploring new technologies, improving my development skills, and working on innovative digital projects.

Projects

macOS Web Environment (This Portfolio!)

Interactive Multi-Window OS Replica

Present

Architected a fully functional, interactive macOS replica directly in the browser to serve as a highly engaging portfolio. Engineered a custom Multi-Window Manager using React state and context, capable of rendering independent, draggable, and dynamically layered web apps and games. Implemented CSS variables for real-time Light/Dark theme switching, native background iframe preservation for uninterrupted media, and sophisticated component architecture to replicate Apple's authentic UI physics and glassmorphism styling.

Dokusho

Cross-Platform Book Discovery App

Personal Project

Designed a Clean Architecture (MVVM) layer structure with strict separation of data, domain, and presentation, enabling 100% shared business logic across Android, iOS, and Desktop with zero platform-specific duplication. Wired Open Library API (20M+ books) via Ktor with 300ms debounced search, persisted favorites offline using Room KMP, and delivered async cover art loading via Coil 3 with Koin providing zero-boilerplate DI across all three targets.

On-Device RAG Assistant

Final Year Major Project

In Progress

Building a fully offline retrieval-augmented generation system using Gemma 3 1B (Q4_K_M quantized, ~600-700MB) for on-device inference, paired with local vector-based document retrieval — enabling context-aware Q&A with zero network dependency. Application layer built with Kotlin Multiplatform / Compose Multiplatform. Benchmarked ~50-150ms query embedding and ~10-50ms brute-force cosine vector search across a few thousand chunks, validating feasibility of real-time on-device RAG on consumer hardware.

Obsidian Ledger

Cross-Platform Finance Tracker

Personal Project

Architected a shared UI module (98% Kotlin) consumed by both Android and iOS targets via Compose Multiplatform, eliminating per-platform UI duplication and keeping feature delivery in a single agile iteration cycle. Implemented offline-first transaction storage with a Repository pattern, and enforced Clean Architecture boundaries across androidApp, iosApp, and sharedUI modules with unit tests for domain-layer use cases.

CareStack

Hospital Operations Backend

Personal Project

Built a modular Spring Boot backend for hospital inventory management, tracking stock and reconciling supplier data on a schedule to surface discrepancies before they become problems. Designed an event-driven backbone using Kafka and Redis-backed caching, with idempotent APIs, scheduled cron jobs, and Flyway-owned schema migrations.

Experience

Software Development Intern

MetaUpSpace LLP | Remote

May 2026 - Present

Contributing to Housizy's Customer and Vendor applications, a KMP consumer platform (Android & iOS) for a B2B construction material delivery service. Developed shared UI modules consumed by both apps and wrote the underlying business logic layer for both; also manage the supporting server infrastructure, including hosting and deployment. Built a temporary Supabase backend to independently test business logic before production integration, and set up and debugged the KMP iOS toolchain while integrating Supabase Google OAuth into the shared authentication flow, unblocking cross-platform sign-in for the app.

Software Development Intern

CodeAlpha | Project-Based, Remote

Sept 2025 - Oct 2025

Shipped 2 production Android apps within 8 weeks following an Agile sprint cadence, collectively handling 500+ concurrent users with <1s response times under live load. Slashed quiz dropout rate by 25-30% via an instant-feedback loop and eliminated 60% of redundant network calls through a local cache layer, cutting average load time from ~800ms to <320ms.
