You will get a bug in your REST API fixed
Project details
Got a bug in your backend that's breaking things or driving you crazy? I'll track down the root cause and fix it properly — not a quick patch that breaks something else next week.
I'm a backend developer with 6 years of experience working daily with REST APIs in Java, Kotlin, and Go, including AWS integrations and production troubleshooting with Datadog and Grafana. Finding and fixing bugs is part of my everyday work.
What you get:
• Root cause analysis — I find why it's actually happening, not just where
• A clean fix that respects your existing code and conventions
• Investigation using logs, your observability platform when needed
• A short explanation of what was wrong and how I fixed it, so nothing stays a mystery
Before you order: message me with the details — what's broken, any error logs, and repo access if possible — so I can confirm I'm the right fit and give you an accurate scope. This keeps the delivery honest for both of us.

Backend Engineer | Reliable REST APIs in Java/Kotlin, Go, AWS, Datadog
Sao Paulo, Brazil - 5:50 am local time
Over the past 6 years as a backend developer (and coding since 2016), I've focused on what keeps a backend healthy in production: clean, well-documented REST APIs, solid AWS integrations, and the observability needed to catch and fix issues before they reach users.
What I can help you with:
- Designing, building, and maintaining REST APIs in Java, Kotlin, or Go
- Integrating your backend with AWS services (compute, storage, messaging, and more)
- Setting up and improving monitoring, dashboards, and alerting with Datadog and Grafana
- Troubleshooting production issues — latency, errors, and performance bottlenecks
- Maintaining and modernizing existing backends without breaking what already works
I care about code that's readable, tested, and easy for the next person to maintain — not clever for the sake of it. I communicate clearly, give honest timelines, and keep you updated so there are no surprises.
If you need a backend developer who can both ship new APIs and keep existing ones running smoothly, let's talk about your project.
