I Connected Telegram, Upwork MCP, and Obsidian with Hermes to Build My Own AI Agent
October 18, 2026 - By Rizwan Aritonang
Right now, I don’t want to pay for a VPS yet. What I wanted was simple: chat from Telegram, run the agent on my Ubuntu laptop, read my Obsidian vault, and help screen Upwork jobs. It sounded clean. On day one? Honestly, it wasn’t all clean. Why I Started Doing This As a web freelancer, my daily work repeats a lot: check Upwork, write proposals, note my agenda, sometimes do email outreach.

July 14, 2026 - By Rizwan Aritonang
TL;DR There’s a habit I’ve picked up lately: looking closely at newsletters that land in my inbox. It’s not the content that catches my eye — it’s the design. Many of them look simple, not overloaded with color, not packed with images, with clean typography and comfortable spacing between elements. Altogether they feel professional. I then wondered: if they can send emails like that, why can’t I? This Idea Started from a Personal Need I wasn’t looking for a new project idea. I simply wanted emails that looked cleaner when I messaged clients. My mental model was simple: build an…
