Analytics / live-opsLive product
Game live-ops platform
Calamity
One platform runs the game’s analytics, campaigns, updates and player tools — no rented services.
- Its own analytics, not rented
- No monthly SaaS bills
- Game news in 14 languages
01 / Independent full-stack engineer
No fixed packages. One engineer stays responsible from the first conversation to launch — and after it.
The site, the admin panel, the app — built to fit your business.
Some businesses need a clean site that sells their service well. Others need bookings, payments, a staff panel and a mobile app. Both are normal work here: a small project gets the same care as a platform.

Live now
Four products you can open and verify.
What I can build
Start with the result, not the technology list.
A useful first version can be small. The same collaboration can grow into the system that runs the business.

Selected work
Four live products. Open the cases and try the working screens.
Start with a real production surface, then use the safe interactive version to inspect the workflow without exposing private data.

Working together
From a first call to a launched product.
Understand the work first
We start from how the business actually runs: who does what, where time is lost and what must never break.
Right-size the solution
You get the smallest version that solves the problem, and a clear picture of what it can grow into later.
Build and launch
Working software early, honest progress along the way, and a launch on real infrastructure — with tests wherever money or data is involved.
Stay close after launch
The products on this site run daily without a developer on call. Support, improvements or a clean handover — whatever fits.
About
I build the whole system, then stay close enough to see it run.
My work spans product, frontend, backend, data and operations. That range matters when a payment callback changes an admin screen, a report changes a campaign, or a staff habit should change the interface.
The projects here are live: a yoga studio platform, an online game’s live-ops stack, an indie publisher storefront and a cafe’s banquet builder.
I prefer few dependencies, explicit rules and software a non-technical team can run without a developer on call.
