Our client wanted to transform their brand to a luxury brand. We created some packaging and animation to showcase and prototype how the packaging would feel to customers before they actually went to large volume manufacture. We used #Figma and #Blender for high quality artwork and 3d design for discussing design options with the client.

Hi Community, Here is a fun 3D landing page we built for one of our clients who were looking to build a modern website showcasing cultural awareness and technical prowess in the advertising space. This was prototyped in Figma, built in Webflow, and the 3D elements were created in Spline.

Can you build a telehealth platform that doesn't require patients to install anything?' That was the Pigeon Healthcare challenge. The solution: SMS/MMS as the patient interface, Flutter as the provider platform, LLMs as the assistant. Patients text naturally. AI summarizes intelligently. Healthcare teams respond efficiently. Unified the mobile and web codebases using Flutter, cut maintenance costs by 60%, and built the messaging bridge that makes it all work. Sometimes the best UX is no UI at all, just the tools people already have in their pocket.

Junín (Argentina). Gurgaon (India). Hollywood. ✈️ As Lead Backend Engineer at Grindr, I built teams across three continents. The codebase was challenging. The reviews were tough. The app still struggles with issues we fought daily. But the engineers I hired in Junín, the late nights debugging with the team in Gurgaon, the friendships across 10,000 miles — that's what I took with me. Sometimes it's not about the code you ship. It's about the people you build with.

Healthcare needs to be accessible everywhere. That meant our code had to be too. The challenge with DocSquad: Build a telehealth platform that works identically on your iPhone, Android device, mobile browser, and desktop — without maintaining four separate codebases. I led the web effort, adapting our Flutter codebase to work seamlessly across mobile and desktop browsers. One team, one codebase, universal access.
