RWELegacy Migration Specialist / Full Stack Engineer

Nov. 2021 - Jun. 2023RemoteI played a key role in a critical project involving the implementation of a turbine alarm system across 10 countries, covering over 3,600 sites. Working closely with both management and technical teams, I meticulously refined the project requirements and uncovered forgotten features essential to the system's functionality. Leading a dedicated team, our primary task was to overhaul a cumbersome legacy application, laden with spaghetti code accumulated over 15 years. We successfully navigated this complex challenge by migrating the outdated system from a custom framework to Symfony 6.3, a modern and robust platform. Additionally, I engineered four efficient microservices, implemented an asynchronous messaging system, and devised comprehensive protocols for message emission and handling. Through rigorous testing and meticulous development, we constructed a reliable and resilient system to ensure seamless operation and enhanced performance.

Additionally, I collaborated closely with stakeholders to understand their evolving requirements and ensure alignment with project objectives. Through diligent analysis and iterative development, I successfully continued the project's trajectory, delivering incremental improvements and solidifying its position as a premier solution in the private aviation industry.
