Fred Wu - experienced Elixir developer (and OSS contributor), available for freelance work
Hi folks,
My name’s Fred Wu, I’m an experienced Elixir developer who has worked on multiple commercial projects as well as released multiple Hex packages.
I work at a fintech startup in Australia as CTO, leading a small team. In the past few days I’ve decided to start moonlighting again, especially now that I’ve been working from home since Covid and has more time and flexibility. I can commit about 20-30 hours a week.
I’d been using Elixir professionally for a few years, lead and built multiple commercial B2B & B2C SaaS projects. Until recently I’ve always been very hands on, and have worked with multiple tech stacks in the past, including Ruby, JS and PHP, and most recently Clojure at the startup I’m currently working at.

As you probably noticed I have quite a few projects on Github. Some of the more interesting ones are:
- Crawler, a high performance web crawler built in Elixir: GitHub - fredwu/crawler: A high performance web crawler in Elixir.
- Simple Bayes, a naive bayes machine learning implementation in Elixir: GitHub - fredwu/simple_bayes: A Naive Bayes machine learning implementation in Elixir.
- OPQ, a simple in-memory queue with worker pooling and rate limiting in Elixir: GitHub - fredwu/opq: A simple, in-memory queue with worker pooling and rate limiting in Elixir.
- And a few years ago when I was heavily involved in the ruby/rails community, I had done an experimental project building a “layer 0” ORM on top of ActiveRecord and Sequel: GitHub - fredwu/datamappify: Compose, decouple and manage domain logic and data persistence separately. Works particularly great for composing form objects!
If you think my skills and experience could add value to the project I’d love to chat more. You could reach me at ifredwu at gmail dot com. Thanks!

Hey folks, I’ve recently wrapped up a project so I’m available for hire again. 
Updated my “pitch” given my recent projects:
I’m an experienced Elixir (and Ruby) dev with ~20 years of experience. I have a day job as a CTO writing Ruby code. On nights and weekends I’d spend time on either freelancing gigs or my own projects - recently I’ve launched Persumi (https://persumi.com/) - a modern blogging platform, built in three months, and Rizz.farm (https://rizz.farm/) - an AI-powered Reddit lead gen platform, built in six weeks. Both were built with Phoenix LiveView and Petal Pro (which I’m also a contributor).
I’m full stack, but my strength is in software architecture, backend systems (Elixir and Ruby), DevOps (AWS) and machine learning (built my own ML libraries in Elixir, very familiar with the latest LLM trends, including agentic workflows).
I also do fractional / consulting CTO gigs, providing tech and product strategies and roadmap work, etc if that interests you. Most recently I’m helping an Australian business with ~$100mil revenue uplifting their tech capability.

I’m based in Australia (GMT+10/11) but I can be a night owl and have some overlapping hours with US and EU. I’m available for 20-30 hours a week, can be more if needed. My hourly rate is $200-300 depending on the project and work.
If you think my skills and experience could add value to your team and project I’d love to chat more. You could ping me here or reach me at fred@wuit.com . Thanks!
