About this gig

A broken form, JavaScript error or failing request can block a feature you need to ship.


I'm Leandro, a Swiss game and software developer and Lead AI Product Engineer (C++) at KRAST GmbH. I work on clearly scoped bugs in existing JavaScript/TypeScript web applications.


Please message me before ordering with the error, steps to reproduce it and the expected result. We will confirm the stack, one issue and the right package.


BASIC: investigation report, reproduction notes and a proposed next step. Diagnosis does not include a guaranteed fix.

STANDARD: one fix agreed in advance, source changes and verification notes.

PREMIUM: the same scoped fix plus regression checks for up to three agreed acceptance cases in that flow.


Each package includes one revision within scope and a concise handover. New features, redesigns, security audits, hosting and ongoing support are separate. Production deployment is only included when explicitly agreed.


AI/API integration work can be discussed as a separate scoped task. Please provide a safe test environment; do not send production passwords in chat.
