You will get API, webhook, and backend integration troubleshooting with action plan
Rising Talent
Project details
I help diagnose API, webhook, OAuth and backend integration issues in existing systems.
This project is designed for clients who already have an integration or backend workflow in place, but something is failing, unreliable, hard to maintain, or unclear to debug.
I have 30+ years of software engineering experience across backend systems, APIs, distributed systems, SQL databases, AWS, production troubleshooting and reliability-focused engineering. I currently work on large-scale production systems where integrations, observability, failure handling and clear architecture are critical.
You will receive a concise technical diagnosis with likely causes, risks, practical recommendations and next steps. This is not a generic review. The goal is to help you understand what is wrong, what should be fixed first, and how to make the integration more reliable.

About Flavio
Senior Software Engineer - Distributed Integration
Portimao, Portugal - 12:58 am local time
I have deep expertise in legacy modernization, transforming C/C++/C# systems into Go + AWS Lambda with zero downtime, safe incremental rollout, fallback mechanisms, and full production continuity. I modernize critical components such as REST APIs, binary parsers, and UDP/TCP gateways while keeping systems running 24/7.
I led the development of truck telematics and logistics platforms processing more than 30 million events per day, serving over 400 enterprise customers. I designed and implemented real‑time data pipelines, communication layers over TCP/IP, UDP, binary protocols, GPRS and satellite networks, and cloud solutions on AWS.
I’m experienced in software architecture, system design, performance optimization, API integrations, microservices, cloud migration, and production troubleshooting. I help companies build scalable backend systems, solve complex technical problems, improve reliability, and modernize critical platforms without service interruption.
