Verified gaming identity platform
GAMERGRAM
A gaming record - players can trust.
A platform where players link their game accounts and build one verified profile - rank, clips and results pulled from the game itself - so coaches, recruiters and squads can judge them on evidence instead of screenshots. We rebuilt its media delivery and database layer and rolled a new interface onto the live product without changing the stack or breaking a feature.
- CDN
- clips served globally
- Replica
- reads split from writes
- Zero
- features broken in migration
- 4 games

How we build
Six Stages.Each comes with a functional deliverable.
The sequence keeps scope, costs, and launch dates aligned and predictable. You retain ownership of every deliverable, even if you stop at any stage. On the left, the production system that powers your product takes shape with each stage.

Questions
Answered before you have to ask.
Anything not covered here, put it in the form below - you'll get a straight answer, not a brochure.
How do projects usually start?+
With a 45-minute call and, if it is a real fit, a short paid discovery. You leave discovery with an architecture document and a fixed quote - both yours to keep, whether or not you build with us.
What does a build cost?+
A focused v1 with web, payments and an admin console typically runs in the mid six figures (INR). Mobile apps, AI workflows and IoT integration add to that. We quote against scope, never against hours guessed on a call.
Who owns the code?+
You do - from the first commit. Repositories, cloud accounts and app store listings are created in your name or transferred to you at handover, with complete documentation.
Do you work with existing codebases?+
Yes. We begin with an architecture review to assess the existing codebase, identify what can be retained, and determine where improvements are needed. We prioritize stability and maintain a clear principle: preserve existing functionality while making changes.
Where is the team based?+
We operate as a remote-first team, working with clients across Asia Pacific, the Middle East, Europe, and the Americas. Our delivery schedule aligns with your business hours, with dedicated overlap windows and all meetings, demos, and releases coordinated in your timezone.
Can you manage the product post-launch?+
Yes. Monitoring, backups, releases, cloud cost control and a monthly roadmap. Many clients keep us on a light retainer instead of hiring an in-house ops person early.
