Contact

The inbox for this site is contact@johanan.in. That address is the only contact channel that should be treated as official. Use it to ask about internships, research collaboration, mechatronics or robotics projects, speaking, or a correction to something published here. Include who you are, what you want, and a deadline if you have one. He reads mail himself; there is no ticket queue and no chatbot in front of the inbox.

A reasonable expectation is a reply within a few days when he is in term, longer during exams or travel. If you do not hear back, send one follow-up. Do not open parallel threads on every social account for the same request.

GitHub: https://github.com/johanan-23 — public repositories. LinkedIn: https://linkedin.com/in/johanan23 — work history. X: https://x.com/johanan_offl. Instagram: https://instagram.com/johanan_offl. These are identity checks and public posts, not a support desk. For anything that needs a decision or a file, use contact@johanan.in.

Location for schema and logistics: Tamil Nadu, India. There is no public street address and no walk-in office. Do not send physical mail unless he has already agreed to a postal address in email.

Do not send unsolicited attachments that execute code, credential-harvesting forms, or requests to launder payments. Do not ask him to stand up an API, OAuth provider, or MCP server that this portfolio does not run. Recruiters: say the role, the stack, and whether the work is on-site in Tamil Nadu or remote. Cold SEO and link-exchange pitches will be ignored.
