I turn your idea into a production ready mobile app

Cover image for A passenger-focused mobile application designed

A passenger-focused mobile application designed to help users book and manage trips while providing a smooth experience for planning and tracking their journeys. I developed the application using Kotlin Multiplatform, Compose Multiplatform, Android, and iOS, allowing shared code and functionality to support both platforms while maintaining a consistent user experience. The project involved building passenger trip workflows, interactive maps, route visualization, navigation-related functionality, and live location tracking. I worked with the Ferrostar Maps SDK to implement map and routing features and provide passengers with useful journey information throughout their trips. I also worked on responsive Compose Multiplatform interfaces, application state management, API integration, location-based functionality, and the different requirements involved in building a production-ready passenger application. The application was structured with a focus on reusable cross-platform components, maintainable architecture, smooth user interactions, and reliable handling of trip and location-related functionality. This project demonstrates my experience building production-ready Android and iOS applications with Kotlin Multiplatform and Compose Multiplatform, including maps and routing, live location tracking, passenger trip management, API integration, and shared cross-platform development.

A driver-focused mobile application designed to help drivers manage trips, navigate routes, and stay connected with their assigned journeys through a modern mobile experience. I developed the application using Kotlin Multiplatform, Compose Multiplatform, Android, and iOS, allowing shared code and functionality to support multiple platforms while maintaining a consistent user experience. The project involved building trip management workflows, route and navigation functionality, live location tracking, and interactive map experiences. I worked with the Ferrostar Maps SDK to implement navigation and routing features, including displaying routes and providing drivers with the information they need while travelling. I also worked on responsive Compose Multiplatform interfaces, application state management, location-based functionality, API integration, and the different requirements involved in building a production-ready driver application. The application was structured with a focus on reusable cross-platform components, maintainable architecture, smooth user interactions, and reliable handling of location and navigation functionality. This project demonstrates my experience building production-ready cross-platform mobile applications with Kotlin Multiplatform and Compose Multiplatform, including maps and navigation, live location tracking, trip management, API integration, and shared Android and iOS development.

Cover image for A Spanish language learning application

A Spanish language learning application designed to help users practice and improve their Spanish through an interactive mobile learning experience. I developed the application using Kotlin Multiplatform, Compose Multiplatform, Android, and iOS, allowing shared code and UI components to support both platforms while maintaining a consistent user experience. The project involved building interactive learning screens, lesson and progress flows, reusable Compose Multiplatform components, application state management, and responsive mobile interfaces. I also worked with REST APIs, local data handling, and in app purchases to support the application's learning features and monetization. The application was structured with a focus on clean architecture, reusable components, shared business logic, and maintainable cross platform code. This project demonstrates my experience building production-ready Android and iOS applications with Kotlin Multiplatform and Compose Multiplatform, including UI development, API integration, local data, monetization, and cross platform functionality.

Cover image for A productivity-focused Android application designed

A productivity-focused Android application designed to help users schedule and manage phone calls instead of relying on manual reminders. I developed the application using Kotlin, XML layouts, Android SDK, and modern Android development practices, focusing on a clean and intuitive scheduling experience. The app allows users to schedule calls for specific dates and times and manage their scheduled calls from a centralized interface. The project involved working with Android background processing, notifications, scheduling logic, local data management, application state, and system-level phone functionality to make the scheduling workflow reliable and practical. I also focused on creating responsive XML-based UI layouts, handling Android lifecycle requirements, managing scheduled tasks, and integrating the application's core functionality with Android's phone and notification systems. This project demonstrates my experience building practical Android applications that combine custom UI development, system integrations, background functionality, scheduling, and reliable user workflows.

Cover image for Base44 "Give it a Glow"

Base44 "Give it a Glow" Competition Submission Project: Bake Me Happy — Artisan Bakery Live Customer URL: https://bakehappy.base44.app/ (https://bakehappy.base44.app/)Live Admin URL: https://bakehappy.base44.app/dashboard 1. The Product Overview What it is: A comprehensive, end-to-end artisanal bakery operating system. 💯 Real-World Utility: Most local bakeries rely on messy WhatsApp chats, manual inventory counting, and phone calls for custom cake orders. Bake Me Happy replaces that chaos with a premium storefront and a highly intelligent backend. 💯 Design Quality: The design utilizes a boutique, minimalist aesthetic that matches the high-end nature of the products. It's fully mobile-responsive and feels like a luxury brand experience. 2. The Automation Depth. Customer-Facing Automations (Revenue & CX) 🚀 3D Cake Customizer & Pricing Engine(Hero): Automatically calculates complex pricing tiers in real-time as users customize their cakes (shape, flavor, layers, custom messages). 🚀 AI Cake Concierge (Superagent): A fully implemented web chatbot that asks customers what they are celebrating and suggests specific cakes from the catalog. 🚀 WhatsApp AI Assistant: A 24/7 automated WhatsApp flow that acts as a virtual cashier—answering FAQs, taking custom orders, grabbing delivery details, and automatically syncing the order to the Admin Dashboard. Business-Facing Automations (Time-Saving & Operations): 🚀 Inventory AI(Hero): Automatically tracks ingredient usage based on orders and generates alerts when stock is critical (e.g., < 3 days remaining), saving the owner hours of manual stock-taking. 🚀 Review AI: Automatically aggregates customer reviews and uses sentiment analysis to categorize complaints (Quality, Price, Packaging) and identify "Taste Trends". 🚀 Bakery Co-Pilot: An admin-facing AI assistant that can instantly generate daily business briefings and competitor intelligence reports. 4. The Story The Before: An Instagram page with 5k followers where custom cake orders were a nightmare of manual DMs, manual price quoting, and guessing when ingredients were running low. The After: An end-to-end luxury storefront and an AI-powered operating system built entirely on Base44 that the business is actively using today! What I built: 🤖 AI Superagent & WhatsApp Bot: 24/7 automated order taking and customer support. 📊 Competitor AI: Automatically tracks local competitor pricing and generates business insights. 📦 Inventory AI: Automatically calculates ingredient burn rates and alerts the owner before they run out of stock. They are saving hours a week, and their customers get a premium, frictionless experience. https://www.loom.com/share/4df48796f863412e997b5559ffc54818
