I’m a senior backend engineer specializing in high-performance server systems.
If your API is slow, unstable, overloaded or causing timeouts — I will analyze, optimize and rebuild the critical bottlenecks.
I optimize:
Slow REST APIs
High CPU or memory usage
Slow SQL queries, missing indexes, bad schema design
Spring Boot performance issues
Node.js event-loop bottlenecks & async problems
Database load (PostgreSQL, MySQL, MongoDB)
Dockerized backend services
AWS performance issues (EC2, RDS, Lambda, etc.)
Microservices communication delays
Caching strategy (Redis, in-memory, HTTP caching)
Deliverables:
Full backend performance audit
Detailed profiling & bottleneck report
Code-level fixes or refactoring
Improved response times
Reduced CPU/RAM load
Deployment + configuration improvements
Clear explanation of everything fixed
Crypto payment (USDC / USDT / DAI / ETH)
Tech stack:
Java • Spring Boot • Kotlin • Node.js • SQL • PostgreSQL • MySQL • Docker • Redis • AWS • CI/CD
If your backend needs serious optimization, this is the premium service you want.
