I am hiring for senior Solidity smart contract developer in India, so I am looking for PEOPLE, not job postings. Identify one named individual per finding, found through something they published publicly in the last 90 days: a conference talk in that field, a technical write-up about work they have actually done, merged contributions to a well-known open-source project, a paper, or a public post saying they are open to work. Give me their name, the specific thing they published, its date, and the public link I found it on. That link is how I will reach out. Public output only: no profile databases and no scraped contact details. Skip conference schedules, speaker indexes and repository listing pages in favour of the specific talk, post or commit, and skip recruiters, staffing agencies, course sellers, conference organisers, vendor marketing posts and job adverts. Do not return the same person twice for the same piece of work.
