DevStream is an emerging web-based ecosystem that reimagines how software professionals share knowledge, collaborate, and monetise expertise through live video. Unlike general-purpose broadcasters such as Twitch or YouTube, DevStream is engineered from the ground up for technical content: live coding, architectural walkthroughs, and peer-to-peer debugging. The platform combines low-latency RTMP ingestion (via OBS or comparable encoders) with adaptive HLS playback delivered from a Vercel-hosted, Next.js front end. A MySQL-backed data layer coordinates user profiles, access control, and real time metrics, while a dedicated WebSocket gateway sustains sub-second chat and Q&A exchanges. Beyond baseline streaming, DevStream introduces three differentiating capabilities. First, a superchat mechanism enables viewers to highlight critical questions or sponsor sessions, providing creators with an immediate revenue stream. Second, integrated collaborative coding panes allow presenters to co-edit snippets or run interactive demos without leaving the broadcast window, encouraging hands-on learning. Third, a lightweight reporting and analytics console aggregates engagement statistics--view duration, chat sentiment, and donation trends--giving streamers actionable insight into audience behaviour. To surface relevant sessions in an ever-growing catalogue, DevStream deploys a transformer-based recommendation engine that weighs code-language tags, historical attendance, and interaction patterns to curate personalised playlists. Security considerations include token-based authentication, TLS-encrypted media delivery, and rate-limiting to mitigate abuse. Early load tests demonstrate the architecture can sustain 1 000 concurrent viewers per stream with start-up delays below two seconds. This paper details the system design, implementation trade-offs, and obstacles--ranging from synchronising video and chat at scale to ensuring transactional integrity for donations. We conclude by outlining how DevStream could lower the barrier to continuous developer education, foster niche expert communities, and open new monetisation avenues for technically focused content creators.
