Legacy EFB Modernization and Production Stabilization
Modernized a production EFB stack, fixed stability issues, and improved delivery workflows for safer releases.
Project overview
A production EFB platform required modernization across legacy and current modules. The goals were pragmatic: reduce production instability, improve maintainability, and ensure the platform could evolve without fragile release cycles.
This work had to be done while supporting ongoing development and operational needs, meaning changes needed to be safe, incremental, and verifiable.
Execution
Nithron delivered a stabilization-focused modernization plan:
- Upgraded a legacy runtime to a modern baseline to reduce technical debt and unblock future improvements
- Refactored a critical search component to resolve a production memory issue and improve reliability under load
- Improved delivery workflows by standardizing CI/CD expectations and release hygiene
- Supported toolchain and process transitions by aligning engineering practices and keeping delivery predictable
- Contributed to incident response and root-cause analysis (RCA) when production issues appeared, focusing on durable fixes over patchwork
The approach prioritized changes that lower operational risk first, then moved to improvements that increase velocity without sacrificing stability.
Project results
The platform became easier to operate and safer to evolve:
- Reduced production risk through targeted refactors and modernization steps
- Improved reliability and maintainability of a critical service area
- Stronger delivery discipline improved predictability of releases
- Clearer workflows and repeatable practices reduced operational friction for the team
“One of a kind service”
Working with Thiago was a pleasure. He’s a reliable full-stack developer who can own complex projects end-to-end, consistently delivering production-ready systems on schedule.
Jorge Martins,
“Excellent results”
We hired Nithron for a specialized data and systems project. As someone with no technical background, what impressed me the most was their ability to translate a complex problem into a simple, functional solution. They made the entire process understandable, secure, and on schedule. I recommend them for their talent, transparency, and results.
Carolina Engelke,
“Highly recommended”
Working with Thiago, the founder and principal engineer behind Nithron, was a great experience. Strong technical judgment, clean architecture, and a clear focus on scalable, long-term solutions. Communication was clear and professional throughout. I would confidently recommend his work for complex software projects.
