CTO: Elixir, Ruby, Rails, Android Developer (and scrum master) with 10+ years experience

I've now completed over 120 sessions on Codementor! I'm a consultant developer who's been coding for over 10 years now; 6 of those years professionally. I mainly work in Rails, EmberJS and Elixir these days, but I've built things in languages ranging from C to NodeJS to Go. I've had the opportunity to have large multi-nationals on my client list such as Mozilla, IBM,, and multiple large financial businesses. Outside of Codementor, I'm a CTO at a Startup in Scotland, as well as a consultant adviser for various startups and small businesses in Scotland and the UK.

Data-driven engineering strategist. Consultant at Trailblazing Technology LLC

Expert programmer proficient in Python, Java, SQL, C/C++, and pretty good with JS/CSS/HTML, too! The main things I can probably help you with are Python/Django/Celery/etc., Java/Spring projects, and DevOps (AWS, DigitalOcean, Rackspace, Heroku... everything from managed deployment services like Elastic Beanstalk or Dokku/Deis to Jenkins, Active Directory/LDAP, and custom ETL solutions).

Jack of all trades, master of some

I've been writing code or reading about software nearly every day for about 20 years. I've been working full-time as a professional software engineer for 12. Software and hardware are super interesting and fun for me, but what I really enjoy is helping other people to learn. I've put together a wiki with some articles and lots of links and resources for people who want to learn to code, learn more about particular topics or up their game: Not only do I have knowledge and experience in specific areas such as databases, web applications, security, networking, Linux, C, and plenty more, I also have real-world experience building commercial products and explaining complex technical concepts in straightforward English to non-technical people.

Software Engineer and Techstars Alumni

I am a self-taught software engineer with the patience to listen and the experience of knowing what works at scale. Through my Startup Weekend experience and time spent freelancing in co-working spaces, I know how to scope and build an MVP. Through my Techstars experience, I know how to ask lots of questions about everything from financial models to implementation details. Through my experience at Quirky and Digital Ocean, I know what breaks when you have millions of users and billions of records and how to solve those challenges quickly. Looking for a mentor? I remember what it was like starting out and remember the kind of mentorship that helped get me where I am today. If your rubber ducky and linter have both failed you, let's talk. Looking for a freelancer? Let's talk about your project and make sure we're 100% clear on the result you are looking for. Your success is my success.

Python expert for Data Applications & Web Dev

I'm a Python and Java/Scala developer, with main focus on Big Data solutions and some full stack web dev experience. I will happily look at your code or system and point out bugs or suggest a better way to do something. Have experience with most popular Python libraries including pandas, matplotlib and numpy. If you want a great code review/refactoring of your Python code, from which you are going to learn and improve as a developer, I am the person to go to. If you have a data transformation that is taking ages, ask me for my help. I have been able to achieve speedups of up to 500x for people here, by using libraries such as pandas in an optimized way and being aware of memory usage patterns. I also am particularly well versed in geospatial data management and the open source project QGIS. I'm a big fan of clean, testable and tested code with a wow factor. I'm also striving for automating everything with the correct tools. I have also worked at Google. I love consulting people via codementor. So far I have walked people through building web apps in Python, solved tough bugs in complex systems and shared my expertise in designing data pipelines. I also have, among other things, helped parallelize code that analyzes DNA sequences, configured git servers and showed people how to get started with unit tests.

Very experienced Python and Postgresql architect with a vast experience in scaling and helping others

Author of Mastering Python (, a book to teach advanced Python programmers everything they need to master the language. No cure, no pay for specific problems. I only accept issues if I'm confident I can fix them in a short amount of time. Always happy to give advice :) Over the last 15 years I've started several companies and according to Stackoverflow I've helped ~3.2 million people using my knowledge. I'm one of the top Python contributors on Stackoverflow and have over 30k points. My main interests are scaling of large infrastructures and websites to millions of users as I did with my last large startup ( I have many years of experience consulting people and companies with varying programming, dba and sysadmin problems. My profile only shows my main expertise but I have experience with a vast array of technologies so please don't hesitate to ask for advice on any matter.
