ReactView Video review for coaches and teams
ReactView lets coaches record a game, review it frame by frame, draw the play, share it with the roster and see which players watched it. We joined mid-development, supported the existing team, and took over product development.

What it is
One place for film study
Coaches have always reviewed film, but rarely in one place. Footage sat on a hard drive, clips went out over messaging apps, tactics stayed on a whiteboard, and no one could tell whether the players had watched any of it.
ReactView brings the whole process into the browser, from the upload to the record of who watched each clip.

The engineering problem
A video app looks like a player and an upload button. Underneath, most of the work is a storage ledger and a permission model.
The product

Cloud storage
Footage stored with automatic backup and available to staff from any location.
The build
How it works
Every screen below is from the live platform, shown with the engineering behind it.
Review
Review, frame by frame
Tag the moments that matter at exact timestamps, comment on them in a thread, and put 2 clips side by side, such as this week's power play next to last month's. Every video has its own privacy setting, share link and folder.
Playboard
Draw the play
A rink diagram with the zones marked, draggable players and pucks, and freehand tools. A set piece drawn on the board records straight into the video library, so every chalk talk is saved as a clip.
Library
Uploads and recordings in one library
Footage is either uploaded from a camera or captured with the built-in screen recorder, which produces most of the film on the platform. Both go into the same searchable library, organized in folders.
Storage
Storage you can see
Every team has a storage allowance that stays visible at all times. Rather than block a coach mid-season with an error, the platform shows the largest and oldest files and lets the coach free up space directly.
Analytics
Who watched each clip
When a clip goes to 20 players, the useful question is who watched it and for how long. For each video, the platform reports views, unique viewers, how much people watched, their device and their location on a live map, all exportable to CSV.
About these screens. All shots are from an internal Neo Carbone account on the live platform. The footage, names and files are our own test material, and no client team's data appears here.
Behind the scenes
The admin platform behind it
With 500+ teams on the platform, operators need to know who a given user is, why a team is over quota and which videos failed overnight. The admin side answers those questions from a single interface.
The whole platform on one screen: usage, storage, live sessions, health and security.
Teams & limits
Organizations expand into teams, each with its plan, sport and live usage against its coach, player and storage limits.
Users & support
Impersonate a user or use ghost mode to see exactly what they see, reset passwords and transfer people between teams, with every action logged.
Media repair
Every video in one filterable table, plus bulk thumbnail regeneration for the files whose frames failed to extract.
Signup moderation
Anyone can start a team instantly, and each new team enters a review queue with its trial, limits and referral source, to keep or delete.
Referrals
Affiliate codes tracked from first signup through to paid conversion, broken down team by team.
Storage ops
Platform storage split by source, with cleanup and health checks that catch files without records and records without files.
Under the hood
What holds it up
Beneath the screens, these systems decide whether a video platform keeps running at 500 teams or fails at 20.
Tenant isolation
Enforced at the data layer, so no one reaches another club's footage with a guessed link.
Media pipeline
Resumable uploads, screen capture, thumbnail repair, and playback links that expire.
Engagement tracking
Accurate watch-through rates, geo-resolved viewers, device splits and CSV export.
Live canvas
Shared board state that merges concurrent edits, with presence and canvas recording.
Quota ledger
Server-side storage accounting at 3 levels, race-safe under concurrent uploads.
Admin & audit
Impersonation behind scoped permissions and a log, plus moderation and attribution.

Your turn
Building a similar product
We apply the approach used on ReactView to any product that has to keep working as its user base grows.
We build the foundations
Tenancy, quotas, media and permissions are what a product stands on. We build them early, before customers and revenue depend on them.
Admin tools from day one
Support staff need to answer tickets and fix problems, so we give them admin tools instead of a database console.
Measured, so you can steer
Anything that matters to the business is shown on a screen the team can check at any time.
Discuss your product with the team
Describe the workflow your product has to support, even without a finished spec. We will tell you what it takes to build and what we would build first.
