Hi! Upgrading a live chat app with seamless in-app video calling while also shaving seconds off app launch and message delivery time is exactly the kind of real-time performance work I enjoy. I’m comfortable working inside existing codebases, making clean, well-commented commits, and benchmarking before/after metrics to prove the gains. I’ve added WebRTC/video features and optimized socket-based messaging in past projects, so I can tighten both UX and speed without disrupting your current architecture. I’ll also include a concise test plan showing measurable improvements. Looking forward for your positive response in the chatbox. Best Regards, Arbaz H

Hi there, I’ve read your plan to add in‑app video calling and speed up chat load times within your live codebase. I’ve shipped real-time features and performance wins in mobile chat apps. I’ll implement in small, incremental steps without rebuilding your existing architecture. How I’d implement it: - Add a lightweight video calling module that plugs into your existing signaling and media stack, with minimal UI changes. - Tighten the chat path: reduce latency, trim payloads, and add optimistic updates with robust retry logic. - Speed up app start: code-splitting, preloading, and targeted profiling, while keeping your repo live. - Provide a short test plan showing message delivery latency and app launch benchmarks, before and after. Availability: I can start immediately and target a two-week delivery window with weekly check-ins. Would you like me to start with a two-week sprint focused on video calling and latency benchmarks? Best regards,

@cindyviorinar

Hi, I’ve read your project and I’m confident I can add seamless in-app video calling and tighten message delivery and app startup without rebuilding your architecture. I work across Java/Spring Boot backends (REST APIs, services, database layers) and native mobile clients—I've integrated WebRTC/Twilio calling, refactored messaging services for sub-second delivery, and performed performance tuning that sped app launch and delivery paths. I’ll work in your live codebase with clean, well-commented commits and deliver a short test plan that shows message delivery and app launch benchmarks before and after changes. I’ll include links to comparable realtime features I’ve shipped when we connect. Next step: I’ll review your repo and current metrics and propose a concise implementation and test plan for your approval. Do you already have a preferred signaling/provider for video calls (WebRTC, Twilio, Jitsi) or should I evaluate the best option for your existing architecture? Thanks, Cindy Viorina
