Your Spring Boot app is slow. Your MongoDB queries are timing out. Your users are complaining.
I fix this. Fast.
Last time I did this, I took a function from 5 seconds down to 60ms (95% improvement). Not in theory — in production, under pressure.
I will do the same for your codebase. In 48 hours, or you don't pay.

HOW IT WORKS
You share your codebase (GitHub, GitLab, or ZIP) — NDA if needed
I analyze and deliver the report or fix within the agreed timeline
Payment via USDT (Binance Pay or RedotPay) upon delivery
⚠️ IMPORTANT — READ BEFORE ORDERING
I only accept USDT (BEP20 or TRC20). I do NOT accept PayPal, bank transfers, or any other payment method.
Why? It's faster, cheaper, and zero delay. I'll send you the wallet address at delivery.
