I’m a senior backend engineer with 20+ years of experience building stable, secure and high-performance systems.
If your backend, API or server infrastructure is broken, slow, misconfigured or producing errors — I will fix it quickly and professionally.
I can fix or improve:
Broken APIs (REST, JSON, authentication, routing issues)
Java / Spring Boot backend errors
Node.js backend issues / server crashes
Database problems (SQL, queries, migrations, indexing)
Performance bottlenecks (slow endpoints, CPU/RAM spikes)
Deployment issues (Docker, Linux, AWS, CI/CD)
Environment variables & configuration problems
Authentication / JWT / OAuth issues
CORS, SSL, proxy, reverse proxy errors
Server logs & monitoring issues
Microservices communication problems
What you get:
Fast and accurate debugging
A clean and stable fix
Clear explanation of the root cause
Optional refactoring or performance improvements
Best-practice recommendations
Crypto payment via LaborX (USDT, USDC, ETH, DAI, etc.)
Tech I work with:

If you want your backend issue solved today, I’m ready.
