I will be your dedicated senior java backend developer for b2b contracts
aliakbargillani
About this gig
Need a senior Java engineer who works like part of your team not a freelancer who vanishes?
For 9+ years I've built payment integrations, ledger & reconciliation services, KYC/AML flows, and high-throughput telecom backends where a rounding error or a dropped Kafka message costs real money.
5.0 Stars on every Fiverr order delivered.
WHAT I BUILD
- Spring Boot REST APIs & microservices
- Event-driven systems Kafka, RabbitMQ, idempotent processing
- PostgreSQL / MySQL / MongoDB / Redis design & tuning
- AWS, Docker, Kubernetes, CI/CD
- Legacy Java 8 17/21 migrations, monolith microservices
- JUnit, Mockito, integration tests
HOW IT WORKS
- You buy a block of dedicated hours 20, 80 (part-time) or 160 (full-time)
- Retainers run as monthly orders: renew, pause or resize each month
- Overlapping hours with your timezone, daily written updates, weekly calls
- Full source code, documented and yours. NDA signed before I start.
Revisions apply to delivered features, iteration during the sprint is billed from your hour block, not counted as a revision.
Extra hour blocks, security reviews & architecture roadmaps quoted on request.
Message me first with your scope I'll confirm availability.

FAQ
Can you commit long-term, beyond one month?
Yes, that's the model. Most clients renew monthly. Retainers run as sequential monthly orders (or milestones), which keeps things clean for both sides. I can commit to 3, 6 or 12 months with a locked rate.
Why do I buy "hours" instead of a fixed feature list?
Because real backend work changes shape mid-flight. You get a fixed price for a fixed block of dedicated time, with scope agreed before each sprint and a clear burn-down of hours used. If you'd prefer a fixed-scope, fixed-price quote, message me and I'll build one.
Can you handle high-throughput, real-time systems?
Yes, event-driven architecture with Kafka, idempotent transaction processing, retry/DLQ handling, and JVM performance tuning. Telecom-scale message volume is where I've spent the last several years.
What timezone do you work in?
Pakistan (PKT, UTC+5). I guarantee at least 4 hours of daily overlap with your working hours and adjust my day for EU or US teams.
Can you join our existing team and codebase?
es. I onboard into existing repos, follow your coding standards, join code reviews and standups, and work in your tools: Jira, Slack, Confluence, GitHub, GitLab, Azure DevOps.
