development position.Important: Please Read Before ApplyingWe are NOT looking for a developer who wants to learn Chatroom or Live Streaming development on the job.If you have only worked on general Flutter applications and have limited or no hands-on experience with Chatroom / Live Streaming apps, please DO NOT APPLY.We are specifically looking for someone who has already built, integrated, maintained, or significantly contributed to production Chatroom / Live Streaming applications.Tutorials, courses, personal experiments, theoretical knowledge, or projects created primarily by following AI-generated solutions will not be considered equivalent to production experience.What We Are Looking ForYou should have strong practical experience with the ecosystem commonly found in modern social Chatroom and Live Streaming applications.Experience with several of the following is highly important:Real-time Voice ChatroomsMulti-user Voice RoomsHost, Speaker and Audience

similar real-time room gamesWallet / Recharge / Transaction-related systemsReal-time synchronization and event handlingYou do not need to have personally implemented every single feature listed above, but you must have substantial real-world experience with this type of application and understand how these systems work.Mandatory Technical RequirementsFlutter and DartStrong production experience

requirement and start working on it without needing the entire Chatroom ecosystem explained from zero.You should be able to:Understand how modern Chatroom / Live Streaming applications workRecognize common technical challenges before they become bugsThink about real-time synchronization and edge casesUnderstand the relationship between frontend, RTC, database and backend logicMake technical decisions independentlyRead and understand an existing codebaseTake ownership of features from implementation through testingBuild production-quality features rather than prototypesCommunicate clearly about technical decisions and problemsAI coding tools are completely acceptable as development tools.However, you must understand the code, architecture and implementation decisions yourself.We are looking for an experienced engineer, not someone who uses AI to learn the entire domain after joining.Communication RequirementHindi communication is mandatory.You should be comfortable communicating in Hindi for day-to-day discussions, requirements, technical discussions and development coordination.Required Previous ExperienceTo be considered, you should have previously worked on at least one real production Chatroom / Live Streaming application.When applying, please provide:Name of the app(s) you worked on, if publicly shareableYour exact role in the projectHow long you worked on the projectWhich Chatroom / Live Streaming features you personally developedYour experience with AgoraYour experience with SupabaseExamples of features such as Gifting, PK/Battles, CP, Frames, Entry Effects, Chat Bubbles, Levels, Games, etc. that you personally worked onLinks to relevant apps, portfolio, GitHub, Play Store/App Store listings, or other verifiable work where availablePlease clearly

general-purpose Flutter developerYou have never worked on a production Chatroom / Live Streaming applicationYou only have theoretical knowledge of AgoraYou have only basic Supabase experienceYou plan to learn Chatroom development after joiningYour relevant experience comes only from tutorials or coursesYou have only built simple chat applicationsYou have no experience with real-time voice/video systemsYou expect the team to teach you the Chatroom ecosystem from scratchYour relevant projects were primarily generated by AI without substantial personal implementation and understandingWe are intentionally keeping this requirement strict.Why This Role Is DifferentRaxvor already has an existing product and a defined Chatroom ecosystem.The right candidate should be able to look at a requirement such as:PK Battle → Gifting → Coin deduction → Real-time room events → Winner calculation → Rewards → Rankingsand understand the type of architecture, synchronization, edge cases and
