Hi Hacker News,
I’m a 19-year-old software engineer and I’ve been building TogetLink to solve a problem I face every day: the noise and inefficiencies in professional networking. Most platforms focus on vanity metrics and connection counts, rather than high-intent professional alignment.
I wanted to create a streamlined, premium experience focused entirely on intent-driven matching.
The Tech Stack:
Frontend & Backend Isolation: Built completely with Next.js App Router. I focused heavily on optimizing server-side rendering (SSR) and isolating our backend API structure to ensure high performance, speed, and strict security boundaries.
Mobile: The mobile experience is engineered via Dart and Flutter to maintain a lightweight footprint and fluid user interface.
Why I’m showing this to HN: We are officially in open testing today, and I registered the company both locally and in Delaware to take this global. However, launching a startup without a marketing budget means hitting a massive distribution wall on day one.
I would love to get the community's feedback on the landing page performance, the overall UX, and how you manage high-intent professional networking within your own ecosystems.
I'll be in the comments to answer any technical questions about the architecture or the stack. Thanks for checking it out!
Like many of us here I prefer not use PowerPoint. Recently I've been making slides in Typst (https://typst.app) which is great, except there's no good way to actually present the resulting PDF, and no support for speaker notes, videos or GIFS.
To fix this I built Presio: https://presio.xyz. Present any PDF in the browser as two synced windows, a controller (speaker notes, timer, media controls) and a viewer for the projector. It handles embedded video and GIFs, including YouTube/Vimeo.
Local by default: your PDF never leaves your browser. Optionally shareable so the audience can follow along on their own devices.
A short GIF explains it best: https://imgur.com/a/ZbvhPnc
Try the an example presentation: https://presio.xyz/present?from=https://github.com/benedict-...
Works with plain Typst, Polylux, Touying and PDFs from LaTeX too (speaker notes supported). Try it for a presentation and lmk what you think!
