Do you find my contributions to OpenStreetMap, Wikimedia Commons, Panoramax, and Mangrove Reviews useful?

If so, please support me on Liberapay, or see other ways to support me.

I’m unemployed, and dedicate all my time to improving the data and software commons. $100/week would be enough for me to make a modest living, but I currently receive less than $1/week.

That’s like 20 people pledging $5/week…doable, right? 🙂


Hi! I’m a software freedom and privacy activist.

I boycott all proprietary software, and improve OSM every chance I get, in the hope of making libre software like CoMaps, OsmAnd, and OsmAPP a viable alternative to proprietary maps.

I use…
* Vespucci for mobile mapping,
* OpenCamera for geotagged photos - good ones go to Wikimedia Commons (check out my Wikimedia Commons uploads), the rest go to Panoramax,
* JOSM for public transport,
* OpenTracks for recording tracks,
* MapComplete for adding ratings and reviews to Mangrove Reviews (see my reviews).

Since 2023, I’ve been organizing monthly mapping parties in Delhi and NCR. See the OSM India Mastodon (with photos!), or the forum thread.

In the past…
* I’ve done a professional ground survey for Médecins sans frontières (a.k.a. Doctors Without Borders), in Delhi’s Bhalaswa, Adarsh Nagar, and Jahangirpuri regions.
* I’ve conducted OSM workshops in colleges, e.g. at IIT Roorkee in collaboration with HOT.
* I’ve organized OSM tables, talks, and workshops at conferences like IndiaFOSS, DelhiFOSS, and FOSS Meetup Delhi.

I have a Git repository containing my (libre) designs for a variety of OSM promotional material.
