Executive Summary

My Maestor is a two-sided service marketplace built by Aionys for customers and local professionals in Bulgaria. The solution includes one cross-platform application for iOS and Android, a separate React administration panel, and the backend infrastructure supporting the marketplace.

Available in English and Bulgarian, the platform connects service discovery, specialist profiles with ratings and reviews, real-time chat, bookings, order management, and subscription payments for professional accounts. Developed between November 2025 and May 2026, the live marketplace gives customers a structured way to find professionals and provides specialists with a new channel for reaching potential clients. A web version is planned for later in 2026.

Client & Market Context

The idea for My Maestor came from a simple problem: finding the right professional for a specific service in Bulgaria was not easy. Customers often had to search through social media, classified websites, or personal recommendations, making it difficult to compare providers and choose someone they could rely on.

Service professionals also needed a better way to present their services and reach new customers. The client saw an opportunity to bring both sides together in one place and make finding and booking local services simpler and more transparent.

Project Challenges

Turning a Business Idea into a Defined Product

My Maestor began as a business idea without a defined product structure. The challenge was to translate the concept into clear user roles, core journeys, functional requirements, and a realistic scope for the first release. The product also needed to support future service categories and growth without making the initial version unnecessarily complex.

Designing Trust into the Marketplace Experience

Customers needed enough information to choose an unfamiliar professional without relying on a personal recommendation. The product had to present each specialist’s experience, rating, reviews, portfolio, team information, and order history clearly and in a way that made them easy to compare. The challenge was to provide meaningful proof without overloading the profile or booking journey.

Connecting Two User Journeys in One Platform

Customers and professionals needed different experiences, but every action had to remain connected. Each customer request had to reach the right specialist, while messages, bookings, order statuses, subscriptions, and notifications stayed synchronized for both sides. The challenge was to support both journeys in one application without disconnected workflows.

Building for Mobile Launch and Future Growth

The first release had to support iOS and Android while connecting one cross-platform application, a separate admin panel, backend services, real-time chat, location sharing, subscription payments, analytics, and notifications. The foundation also needed to support more users, specialists, service categories, locations, and a future web version as the marketplace grew.

Our Solution

My Maestor brings service discovery, provider comparison, real-time chat, bookings, order management, and professional subscriptions into one connected experience across iOS and Android. A separate React administration panel gives the My Maestor team the tools required to manage and monitor the marketplace.

Structured Service Discovery

My Maestor home screen: search, service categories and featured specialists

My Maestor organizes local services into clear categories and allows customers to filter specialists by relevant criteria and location. Provider information follows a consistent structure, making it easier to find and compare available professionals.

Provider Profiles That Support Trust

My Maestor specialist profile with rating, location, experience and skills

My Maestor gives each specialist a detailed profile with experience, services, ratings, customer reviews, portfolio examples, team information, and order history. Customers can review this information before requesting a service and make a more informed choice.

A Connected Customer Journey

My Maestor connects the main stages of ordering a service in the mobile application. Customers can find a specialist, review their profile, discuss the request through real-time chat, arrange the service, and follow its status. Booking details, messages, order updates, and notifications remain connected throughout the process.

Tools for Service Professionals

Service professionals can create profiles, list their services, showcase completed work, receive requests, communicate with customers, and manage active orders. Ratings, reviews, and order history help them build a visible reputation, while subscription plans support their continued presence and activity on the marketplace.

Marketplace Administration

A separate administration web application gives the My Maestor team tools to manage users, service categories, promo codes, and professional subscriptions. It also helps administrators monitor platform activity and maintain marketplace operations. The administration application is built and hosted independently from the mobile application.

Product Development Process

The project followed five stages, from product discovery to post-launch support. Between November 2025 and the first mobile release at the end of May 2026, Aionys defined, designed, developed, tested, and launched My Maestor. Product development and digital marketing support continued after release.

  1. Discovery & Strategy

    We turned the initial idea into a clear product plan. Together with the client, we defined the user roles, key workflows, product requirements, and features needed for the first release.

  2. UX/UI Design

    We designed connected experiences for customers and service professionals. The main focus was making service discovery, provider comparison, communication, booking, and order management clear and easy to use.

  3. Software Development

    Aionys developed My Maestor as a cross-platform marketplace for customers and specialists on iOS and Android, with a separate React admin panel and a shared backend. The platform connects profiles, services, bookings, subscriptions, real-time chat, orders, location sharing, and analytics.

  4. Quality Assurance & Release

    Aionys tested customer, specialist, administration, subscription, and payment workflows across the supported platforms and resolved issues before release. The team prepared and published My Maestor on the Apple App Store and Google Play, with the first mobile version released at the end of May 2026.

  5. Post-Launch Support

    After the release, Aionys continued improving My Maestor and adding new functionality. The team also supported the market launch through digital marketing activities, including the first advertising campaign.

Technology & Architecture

My Maestor combines a cross-platform marketplace application for iOS and Android with a separate React administration panel, backend services, payments, analytics, data storage, and Azure infrastructure. Each technology addresses a specific product requirement.

React Native & Expo

My Maestor serves customers and specialists on iOS and Android. React Native and Expo allowed three full-stack developers to build both apps from one TypeScript codebase, reducing duplicated work and keeping features consistent. The same codebase will also power the upcoming web version. Eligible over-the-air updates can reach installed applications without a new store release.

.NET Backend & API

My Maestor’s marketplace backend manages bookings, professional subscriptions, payments, and real-time messages. A layered .NET 9 architecture centralizes business rules, while SignalR powers live chat. A versioned REST API connects the application and React admin panel without breaking older app versions as new endpoints are introduced.

Maps & Analytics

My Maestor uses Google Maps with React Native Maps so customers and specialists can share locations, including live location, directly in chat. Firebase Analytics tracks registration, search, booking, and subscription flows. These insights help the product team identify friction and prioritize improvements based on actual user behaviour.

Data & Performance

My Maestor stores connected marketplace data for users, specialist profiles, orders, schedules, and subscriptions. SQL Server with Entity Framework Core keeps transactions consistent and supports safe database migrations. Redis caches frequently requested information, reducing database load and keeping specialist searches responsive.

Subscription Payments

My Maestor uses Stripe to manage professional subscription plans, recurring billing, and promo codes. Stripe processes card data outside My Maestor's infrastructure, reducing exposure to sensitive payment information. Verified webhook signatures help ensure that only authentic payment events are processed by the marketplace.

Azure Infrastructure

My Maestor runs on Azure App Service, with separate development and production environments deployed automatically from GitHub. Azure Blob Storage stores photos and files, while Azure Communication Services sends transactional emails. Application Insights monitors production performance and helps the team identify operational issues.

My Maestor moved from the start of the project in November 2025 to its first mobile release at the end of May 2026. By September 14, 2026, less than four months after launch, the platform had passed 1,000 registered users and entered the Business app rankings in Bulgaria.
