Hack Day Bengaluru

One room in a global festival.

Hacktoberfest is the month-long celebration of open source that DigitalOcean started in 2014. In 2026 it was run by Major League Hacking and DEV, presented by DigitalOcean, around the theme “AI belongs to everyone”. The format changed this year: alongside the online program, more than 500 in-person events ran across 70+ countries and territories.

Hack Day Bengaluru was one of them: ten hours of building with open-source AI at flo101 in HSR Layout, with two prize tracks, Best Open-Source AI Project and Best Use of Gemma 4. I was one of four organizers and owned the design end to end.

My roles

01Design

The visual system for the day: eight print pieces, from name stickers to a 6 ft standee, and the LinkedIn posts that promoted it. Built at print size with bleed, then converted to CMYK.

02Organizing + photography

I co-organized the event as one of a team of four, with flo101 as hosts. On the day I photographed and filmed it, from check-in through hacking, demos and the prize ceremony.

03Mentoring

I mentored a few teams on the design side of their projects: UX, usability and heuristics, interfaces, flow.

Built on the Hacktoberfest 2026 identity.

The pixel stairs and bars come from the brand guide. The copy borrows the language attendees use every day, so the room reads a little like a repository.

A3 PORTRAIT

One face carries the day’s schedule, the other the Wi-Fi, house rules and where to find help. Each A3 sheet prints two tents that fold into an A-frame on their own base.

The house rules were written with our host’s past events in mind, to keep his office and team comfortable.

Teams wrote in their name, project, track and contributors. The back reads “Shipped at Hack Day Bengaluru.”, so each tent goes home as a keepsake.

3 × A3 portrait posters

The venue is on the first floor, so the route starts on the stairs. One poster at the bottom, one at the top landing pointing to check-in, and one for the washrooms. They replaced the floor decals from the first draft.

Sticker wall

A1 portrait

A blank grid that filled up with attendees’ stickers and Post-its through the day.

It also worked as a meeting point: people could leave their handles so others could reach them, and pinned job openings at their own companies or ones they had heard about.
