You will get Review and Optimization of your Java Spring Boot backend
Project details
I help companies find and fix what's slowing down, breaking, or putting their Java Spring Boot backend at risk — before it becomes a production crisis.
With 7+ years building telecom-grade distributed systems, I've scaled services from 250 → 800+ TPS, improved reliability from 65% → 99.9%, and boosted query performance 4x through targeted indexing and caching. I don't just spot problems — I tell you exactly how to fix them, ranked by what matters most.
What makes this different from a generic code review: I've built and debugged systems at scale in production. I know what breaks under load, what creates security gaps, and what turns into a rewrite 6 months later. You get a senior engineer's eye, not a checklist tool.
You'll receive a structured written report with severity rankings, specific file-level findings, and actionable recommendations. Standard and Premium packages include a recorded video walkthrough so nothing gets lost in translation.
If your backend is live, growing, or about to launch, this review could save you weeks of debugging later.

About Abid
Fullstack Developer | Microservices | High-Perf. APIs | AI Backend
Dhaka, Bangladesh - 5:05 pm local time
I'm a full-stack developer and Java backend engineer with 7+ years building systems that scale — from telecom platforms handling 800+ TPS per node to enterprise microservices serving 10K+ concurrent users. I've taken services from 65% reliability to 99.9%, improved throughput 3x overnight through caching and DB tuning, and modernized Java 6 codebases to Java 21 without the horror story.
What makes me different: I think in architecture first, code second. Before writing a line, I understand your load patterns, failure points, and growth trajectory. That's how you avoid expensive rewrites 6 months later.
Where I add the most value:
✔ Spring Boot / WebFlux microservices from scratch or inherited mess
✔ Performance bottlenecks (latency, throughput, DB, caching)
✔ Event-driven systems with Kafka, Redis, async patterns
✔ Secure APIs (OAuth2, JWT, Keycloak)
✔ AI-integrated backends — RAG pipelines, vector search, LLM APIs
✔ Legacy modernization (e.g. Java 6 → 21 migrations)
I also use AI-assisted development to move faster on full-stack integrations, so you're not paying two people when one can handle it.
If your backend is a bottleneck — or you want to build one that won't become one — let's talk.
Steps for completing your project
After purchasing the project, send requirements so Abid can start the project.

Abid works on your project following the steps below.
Revisions may occur after the delivery date.
Codebase Access & Kickoff
I review your repo and any notes you've shared. If anything is unclear I'll send a short list of questions within 24 hours so we're aligned before I dive in.
Deep Dive Audit
I go through your architecture, code quality, performance patterns, security layers, and database design systematically using profiling tools and manual review.
