I don't approach projects as isolated coding tasks. I look at the complete system — architecture, APIs, data flow, frontend, integrations, performance, and deployment.
For new products, I help establish the right technical foundation. For existing applications, I can work within an established codebase, identify bottlenecks, refactor critical areas, and add new functionality without disrupting the product.
