You will get High‑Reliability Backend Architecture for Critical Systems
Rising Talent

Project details
I design and implement reliable backend architectures for mission‑critical systems, focusing on distributed components, fault tolerance, and high‑confidence data flows. My work combines deep systems engineering experience with hands‑on development in C++, Go, and C#, ensuring robust integrations, predictable behavior under load, and long‑term maintainability.
This project stands out by delivering not just code, but a complete reliability‑driven architecture: clear module boundaries, resilient communication patterns, optimized performance paths, and infrastructure‑ready components that support scale and operational continuity. Clients receive a technical foundation built for real‑world constraints — latency, concurrency, failure scenarios, and interoperability across heterogeneous environments.
Whether you’re modernizing an existing platform or building a new critical service, this project provides senior‑level backend engineering with a focus on stability, clarity, and future‑proof design.

About Flavio
Senior Software Engineer - Distributed Integration
Portimao, Portugal - 10:04 pm 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.
Steps for completing your project
After purchasing the project, send requirements so Flavio can start the project.
Delivery time starts when Flavio receives requirements from you.
Flavio works on your project following the steps below.
Revisions may occur after the delivery date.
Analyze backend goals and context
I review what you want built or improved and evaluate your current architecture to define the reliability scope.
Map technical artifacts and access
I examine logs, schemas, API contracts, metrics, and validate environment access to prepare the integration and architecture work.
