Spring Boot Production Rescue: Kafka, Database and Performance Fixes
Pakistan
Inglese, Urdu
Chi sono
Senior Java engineer specializing in Spring Boot production rescue: I diagnose and fix the issues that take systems down — Kafka consumer lag and rebalancing, HikariCP pool exhaustion, database deadlocks, JWT/auth failures, and Spring Batch job crashes. 5+ years building and operating core banking microservices (Java, Spring Boot, Kafka, Redis, PostgreSQL, MySQL), where downtime is not an option. I also build fast, SEO-optimized Next.js sites with proven Core Web Vitals and PageSpeed results. Clear diagnosis first, minimal safe fix second, root-cause explanation always.

It’s very hard to convey what you’re looking for. There was really very little creativity. I kept asking for something and he just wasn’t getting it. Its just his level of expertise that’s all. If you need a simple cheap idea, then try it. I personally would not use again.

Took 5 revisions, most of them were due to small misses like not providing the requested files, small quality issues, uneven spacing, etc. A lot of time and back and forth was needed to get to the final product. I hired another designer to do the same work and they did it with only 2 revisions and higher quality.
