Sideout

Sideout is a platform created to connect the beach tennis and beach volleyball community around players, venues, events, and local experiences.

The project was born from the perception that the sports life of these communities is still very fragmented: WhatsApp groups, scattered Instagram profiles, manual lists, informal recommendations, and little structure for discovery. For users, finding where to play, following events, or discovering new venues can be difficult. For venue owners and organizers, promoting schedules, tournaments, and activities also requires constant effort across scattered channels.

Sideout’s purpose is to transform this dynamic into a more organized, social, and scalable digital experience. The product combines a mobile app, public website, venue pages, events, profiles, and community features to create its own foundation for discovery and relationships within the sport.

What was built

Sideout includes a mobile app focused on the users’ social experience and a public website designed for acquisition, SEO, page promotion, and product presentation.

The main elements of the platform include:

• a mobile app with a social experience for players;
• a public website with institutional and indexable pages;
• user profiles and community structure;
• venue pages with information, location, and contact channels;
• shareable event pages;
• venue submission and discovery;
• a notification and user communication system;
• infrastructure for transactional emails;
• image and media storage and delivery;
• a technical foundation prepared for monetization features and tools for venue owners.

Role in the project

In this project, I worked across the entire product build: from defining the concept and initial features to technical architecture, implementation, publishing, and growth experiments.

The work involved making product decisions in a still-validating scenario, balancing what needed to be built for end users with what could generate value for venues, organizers, and partners. This included structuring flows for registration, discovery, public pages, email communication, notifications, mobile experience, and web presence.

Beyond development, the project also required strategic decisions about positioning, user acquisition, SEO, domain strategy, communication with venue owners, and possible monetization models.

Product and technology decisions

Sideout was built with a focus on mobility, validation speed, and the ability to evolve. The choice of React Native with Expo makes it possible to maintain a modern mobile foundation for iOS and Android, while the public website works as a discovery, authority, and organic growth layer.

The architecture uses Supabase as the main backend, with database, authentication, and a structure for relational data. Cloudflare and R2 are part of the web and media infrastructure, while Listmonk and Amazon SES support communication flows, and Stripe prepares the path for future paid features.

The project prioritizes:

• mobile-first experience;
• local discovery of venues and events;
• shareable and optimizable public pages;
• structure for user-generated content;
• communication through notifications and emails;
• flexibility to test community, marketplace, and monetization models;
• progressive growth without depending on closed platforms.

Result

Sideout currently works as its own digital product in an active phase of validation and growth. More than an app, it represents the construction of an infrastructure for a sports community: a place where players can discover opportunities to play, venues can gain visibility, and events can circulate more easily.

The project also demonstrates my ability to build a complete product from scratch, connecting strategy, design, mobile, backend, infrastructure, communication, and user acquisition in a real platform.

Sideout is a practical example of product-oriented development: starting with a clear opportunity, building a functional technical foundation, launching it, learning from real usage, and evolving based on the community’s behavior.
