Umair Bin Rafique
Senior Software Engineer | PHP / Laravel | Backend & Full-StackSenior Software Engineer with 8+ years of experience building and maintaining production enterprise web applications, REST/SOAP APIs, and multi-system integrations. My core expertise centers on clean backend architecture with PHP and Laravel, reactive web interfaces with Vue.js, and robust relational and cache storage with MySQL, SQL Server, and Redis.
I have built an independent .NET CLI tool to automate multi-environment Metabase dashboard deployments, engineered visual node-based call-flow builders scaling to 100+ agents, led zero-data-loss migrations from Microsoft Access to SQL Server ERPs, and previously delivered full-stack software for a US-based team in a fully remote capacity.
