How I work
ApproachI work with a few strong principles: sound architecture, explicit rules, and security from the start.
Architecture before implementation
Good design avoids unnecessary debt.
I define domains, contracts, and data flow before implementation starts.
More clarity, less rework.
Backend and APIs with explicit business rules
Critical logic belongs on the server.
I centralize rules, validate inputs, and protect sensitive actions.
Fewer errors, more consistency.
Security integrated into delivery
Security is not a last step.
I apply validation, access control, and risk review from the start.
More robust and trustworthy systems.
