Full-stack developer who takes a product from the data model to production: scope, architecture, implementation and deployment in the same pair of hands.

The work usually starts as an operating problem: a counter that closes late, a queue nobody can see, an app that stutters on a cheap phone. Technical decisions come after that and are measured against it, which in practice means Android builds trimmed until they start without waiting, delivery resolved at the edge instead of on the visitor's device, and desktop tools that replace the spreadsheet.

How I work

Constraints first

Scope, RAM, weight and time are numbers before they are opinions: a build that misses them is rewritten, not shipped.

Measure, then change

Every decision is checked against a real usage cost — startup, bytes, memory. If it can't be measured, it isn't claimed.

Subtract before you add

The fastest code is usually the code that isn't there. Every dependency has to buy its weight.
