I will fix your roblox game lag and low fps
Aleksandr
About this gig
Your game runs fine in Studio and then dies with 20 players in a server. That is what I fix.
I spent 4 months as the only scripter on a live military RP game. What changed:
FPS: 3 to 63
Worst frame: 2881ms to 104ms
Server physics: 0.32 to 59.9 steps per second
The cause was one physics callback eating 92.6ms out of a 97.7ms frame. Nobody had ever profiled it. That is usually how it goes, the fix is small once you know where to look.
On the same game I also found and removed 2 backdoors and closed the remotes where the server accepted damage, explosions and ammo from the client with no checks.
How I work:
1. You give me access to a copy of your place
2. I profile it and find what is actually slow, not what looks slow
3. You get a written report with real numbers, before and after
I do not guess and I do not rewrite your whole game. I find the thing costing you the most milliseconds and I fix that.
Message me before ordering. Tell me what your game does and how many players are usually in a server, and I will tell you straight whether I can help.

I fix Roblox games that are broken under the hood.
4 months as the only scripter on a live military RP game. Took it from 3 FPS to 63 and cut the worst frame from 2881ms to 104ms. Found and removed 2 backdoors and closed remotes where the server trusted damage and ammo from the client. Also fixed DataStore conflicts and Robux purchases that charged without granting.
Shipped my own game solo.
FPS and lag fixes, backdoor removal, DataStore and save systems, monetization, gameplay systems and UI.
Written report after every stage. Fixed price agreed before I start.
FAQ
What access do you need?
Studio access to a copy of your place, or the place file. I never need your account password. If you cannot share the place, I can work from a video of the lag plus your scripts, but the diagnosis will be less precise.
Can you guarantee my game will hit 60 FPS?
No, and anyone who guarantees a number without seeing your game is guessing. What I guarantee is that you get real measurements of what is slow and an honest answer on what can be fixed and what cannot.
My game also has exploiters. Can you help?
Yes. The Premium package includes a security pass: backdoor scan and checking which remotes your server trusts from the client. On my last project I found 2 backdoors running third-party code on the server.
Do you work on data loss and DataStore problems?
Yes, that is a separate service. Message me. I have fixed two parallel systems writing to the same DataStore and rebuilt saving with session locks and a write queue.
What do you deliver at the end?
Fixed scripts plus a written report: what was slow, what I changed, and before and after numbers. No vague summaries.
