The Verdict: Not eligible
There is no working holiday scheme for your citizenship, so this route is closed. Look at the Accredited Employer Work Visa or a student visa instead.
Each scheme is a bilateral agreement with one country, and there is no general version. Eligibility follows citizenship, not residence, so a second passport could bring a scheme with it; if so, go back and answer yes.
The Accredited Employer Work Visa has no age limit. It needs an offer of at least 30 hours a week from an accredited employer, an approved job check, and two years of relevant experience or a level 4 qualification. It runs for up to five years and can lead to residence.
A student visa can carry limited work rights, and post-study work rights afterwards. A visitor visa allows up to nine months in eighteen, with remote work for overseas employers and clients.
