travoom

## Company Description We are pausing travoom to focus on **oleolesport.com**. OleOle is developing a completely free social network and messaging platform for football (Soccer), sports first super app. The primary revenue model will be gambling focused on in-match play. A completely different model than the existing leaders, we are using the Stake.com blockchain strategy. E-commerce similar to WeChat will also drive significant revenue. We intend to operate our own crypto marketplace, our own NFT marketplace, not to mention the mini program marketplace. Lots of good technology out there owned by startups that are out of cash and lack enough users to make it on their own. **OleOle** **Who We Are** **OleOle** is building a decentralized social network and messaging platform for global football fans — think Twitter + WhatsApp + TikTok + theScore + WeChat, built natively using **Rust**, WebAssembly, and blockchain-compatible architecture.

From football content to commerce, ticketing, gaming, NFTs, and crypto betting — we’re building a super app for sports. This is a once-in-a-lifetime opportunity to be a founding engineer at a startup aiming to reshape how sports communities engage digitally — from the Champions League to the World Cup. **What we do...** oleolesport.com empowers people to identify football experience and without any search requirements, simply presents the traveler with vetted components necessary to bring the trip to life -- tickets, lodging, flights and beyond. And we are building a football super app. **Why we are better...** oleolesport.com’s searchless travel approach means a soccer/football experience can be discovered, planned and purchased in a matter of minutes without the endless search-driven lunacy and inefficiency that comes with all travel planning. There isn't a sports social network; oh some claim to be, however they lack even the slightest understanding of network platforms. ## Job Description **What We’re Looking For** ### About the Role We’re looking for an experienced Rust developer to join our core engineering team building high-performance backend services. You’ll work on scalable APIs, data pipelines, and video-processing infrastructure, helping us deliver a cutting-edge platform for millions of users. ### What You’ll Work On - Backend services in **Rust** (non-blockchain; token experience a plus) - Designing and implementing APIs (REST and/or GraphQL) - Building and maintaining **PostgreSQL** data stores - Deploying and scaling systems on **AWS** - Participating in the full **Software Development Lifecycle (SDLC)**: requirements, design, coding, testing (unit, integration, end-to-end), and release - Optional projects: **ETL/ELT data pipelines**, large-scale **video processing/storage/serving** on AWS ### Must-Have Qualifications - 3–5+ years of professional software engineering experience - Strong production Rust skills (not just hobby projects) - Solid understanding of REST and GraphQL (able to explain trade-offs) - PostgreSQL experience - Familiarity with AWS services (EC2, S3, RDS, etc.) - Experience with agile or scrum workflows and multiple types of testing ### Nice-to-Have Extras - Rust **+ GraphQL** experience (substantial bonus) - ETL/ELT pipeline development - Experience processing, storing, or serving large volumes of video content on AWS ### What You’ll Be Building You’ll lay the foundation for an ambitious native Rust platform that includes: - A decentralized social graph with public profiles, clubs, and messaging - Real-time chat and video sharing (similar to WhatsApp and TikTok) - A blockchain-integrated, no-fee marketplace with cashback in OleOle tokens - A multilingual content engine with AI translation into 200 languages - A mini-program ecosystem allowing brands, teams, and creators to build apps inside OleOle (like WeChat) You’ll own and scale: - Authentication and user identity (phone-based and wallet-based) - Token-based rewards system - API architecture for mobile and web frontends - Messaging and real-time communication (event streams, sockets) - Smart routing, caching layers, and database infrastructure ### Project Scope and Vision This isn’t a basic MVP — OleOle is aiming to be the dominant global platform for sports fans: - Supporting over 200 countries, 20,000 professional teams, and millions of fans - Disrupting the ticketing, media, betting, content, and e-commerce industries — across football, basketball, and beyond - Backed by exclusive partnerships with federations like the Asian Football Confederation, and expansion plans into Latin America, Europe, and Asia - Launching in 200 languages with global crypto wallets, real-time updates, and embedded commerce We're not just building an app — we’re building an ecosystem.
