Omid Sayfun

I'm a senior software engineer working on payments at Coda.co, living in Amsterdam.

I have spent most of my career working in FinTech and e-commerce businesses. I am an early adopter, and you will usually find me trying out new tools or products. In the evenings, you will either find me working out at the gym, coding on a side project, or playing padel.

Writing

I write about my personal learnings, insights, and discoveries that I find interesting enough to share.

Projects

I'm always working on some side projects. Some of them are just for fun, some of them are for learning, and some of them are for solving a problem that I have. Here are some of my current projects:

  • pgVector for Typescript course - I spent a lot of time in 2025 working on vector databases and building AI agents and created this course to help you get started with vector databases.
Travel

I have been fortunate to have traveled to many countries. My goal is to visit 30 countries by the end of 2030.

Stack

I use an extensive list of tools and software in my daily life. I can't live without some of them (painkillers) and some of them are just nice to have (vitamins). Here is a list of my current stack:

  • Raycast - Give it a shot and you will never want to go back to macOS spotlight.
  • Bartender - I have a million menu bar icons and this is the only way to manage them.
  • cmux - This is the best terminal replacement and fully integrated with most of coding agents.
  • OpenWhispr - You speak 3x faster than you type. Who knew?
  • BetterDisplay - Best tool to manage your external monitors on Mac.
  • Telegram - I use Telegram for everything. It is the app that I use first thing in the morning.
  • Beekeeper Studio - best SQL editor that I have used.
  • Visual Studio Code - I migrated back from Cursor and use VS code as a git diff review / text editor.
  • ChatGPT Codex - Rate limits on codex is crazy!
  • OrbStack - The best way to run Docker containers on macOS.
  • Macbook Pro , Airpods Pro , iPhone Pro - I'm a heavy Apple user.

Content

I subscribe to a number of different newsletters and youtube channels. I try to read anything that teaches me something new. Most of them end up in my AI agent inbox and I just read the summaries. Here is a list of my favorite ones that I fully read and recommend:

  • Naval - I have been following Naval for a long time and I find his content to be very insightful. He talks about startups, investing, and life in a very philosophical way.
  • Collaborative Fund - Reading Pure Independece by Morgan Housel and I was immediately hooked. They write about economics, markets, and investing in a way that is very easy to understand and has great storytelling.
  • The Diary of a CEO - Steven Bartlett interviews successful people from different fields and they talk about their journey, mindset, and life in a very honest way.
  • Farnam Street - Introduced by Naval and I have been a fan ever since. They write about mental models, decision making, and learning applicable to real life.
  • Mark Manson - I got bored in the middle of his most famous book, searched his newsletter and resonated a lot with it a lot more. He writes about self improvement, philosophy, and life in a very honest way.
Contact

I try to be active on social media but I'm not very good at it. The best way to reach me is via email. I check my email every day and I try to respond to everyone.
