Top Senior Python 3.x Developers of July 2017

Founder of a Ruby on Rails consultancy, 18 years of full-stack development in multiple languages

Howdy! If you work with me, you'll find that I'm patient, a good listener, and am great at tracking down annoying bugs. I used to ran one of the largest Ruby on Rails shops in the world. I started as a Rails Engineer, shot up the ranks, and eventually ran the company as Partner and de-facto CEO. Before and after, I've worked as a freelance full-stack developer in a wide variety of languages. I fell in love with programming in 1997 and have been loving it ever since.

full-stack developer ● IT architecture & strategy ● DevOps ● smokejumper

Solid programmer. Great trouble-shooter, debugger, and "OMG! Everything is on fire! HALP!!" first responder. Especially good at complex integration and automation. Having "jumped the fence" into new programming languages and communities multiple times, strong mentor for just getting into new toolsets and approaches, or moving into cloud/DevOps deployments. Heavily using Python, JavaScript, nodejs, jQuery, d3.js, HTML, CSS, SVG, and LESS. Have worked extensively with PHP, WordPress, Perl, Java, SQL, MySQL, PostreSQL, XML, ODF, NoSQL, and a bunch of other stuff. Interested in, but have not relied on Ruby, Go, Julia, Rust, D, and Nim in production code. I can get in the wayback machine and do C, bash, awk, Ada, Pascal, Modula-2, Icon, LISP, Prolog, and Smalltalk, depending how far back you want to go. We'll pretend that BASIC thing never happened, s'ok? I've programmed inside the Unix kernel, distributed multi-threaded middleware, GUIs, application code, numerical/HPC, and more.

Software Development Engineer @ Amazon

I'm a Master student of Software Engineering and a soon to be SDE at Amazon (Alexa Language Technologies). I've done a couple of internships during my studies, including ones at Nvidia (Linux graphics drivers), Microsoft (Office, primarily worked on projects related to MS Word and MS Sway) and Amazon (I work on Text-to-Speech framework for Amazon Polly and Alexa). I've been programming for around 10 years now. I also used to be a Student Teaching Assistant and I find teaching/mentoring extremely motivating - sometimes I'd get introduced to new interesting topics that I'd probably never think of finding out about on my own if it wasn't for the purpose of explaining it to someone else. Sometimes I'd get a completely new perspective on subjects I thought I knew when trying to find a way to present it to someone else. I'd really love to keep learning this way. One of the topics I'm always happy to talk about are the interviews - I've done a fair share of them, most of them in top tech companies and I would love to share what I've observed so far. I'm always up for tackling interesting interview questions, doing mock interviews or just giving resume tips (I got my interviews at Amazon without a referral, so I might know a trick or two to make your resume stand out. :)) Other than that, you can always reach out to me if you have questions related to Java, Python, C, C++, Android, SQL, GIT, Mathematics etc. I try to keep my knowledge and skills up to date and learn something new every day by helping you!

Senior Web Developer

I do the whole stack! From backend to frontend I build solid applications that are tested and work years down the road.

I just want to help you.

I really like solving problems. Especially connected with algorithms, which involves thinking. It gives me pleasure if I can help someone. I did a lot to be very good at algorithms, competed in many algorithm competitions and now I am on the other side - I create problems for such competitions and try to share of everything I learned earlier (because of these competitions).

Full-Stack Software Engineer

I am an experienced full-stack software developer, primarily in Django development for web applications. I lead a team at a custom software agency in the South East of the US.

Expert Lead Software Engineer and Mentor

DISCOUNTED RATE - I am offering a reduced rate for a limited time as I am new to the codementor platform. My heart is in Scotland, but I live in Bristol UK. I have over 10 years coding and teaching experience. I have previously worked at a leading British University, a top UK Security Consultancy and currently one of the foremost Consulting and Technology companies in the world. I am also a published Computer Scientist in Human and Computer Interaction.

Senior Engineer

I especially enjoy working with early stage startups. I spent many of my formative computer science years in academics, worrying about low level computer science concepts including: logic & mathematics, algorithms, computational complexity, data structures, and language design. My strength in these core concepts allows me to quickly learn new languages, and to easily understand new problems.

Let me help solve your toughest problems.

I pride myself on my ability to write solid, well documented and fully tested software. With the projects that I have worked on, my software has not only needed to hold up to use by its users, it has also needed to be able to withstand scrutiny in court. As a result, I take writing quality code very seriously. Over the last few years I have worked on creating a platform to revolutionize the way that investigators (of all kinds) explore unstructured data, primarily text documents. I did this by taking advantage of the latest technologies and techniques in information retrieval and natural language processing. I also created a simple yet powerful language that allows investigators to ask deeper questions of the data. The end result of all of that effort is a system that allowed a forensic accounting team, of just two people, to go through a collection of over 500,000 documents and find emails that allowed them to receive $4,000,000 in damages for their client. The original target was only $250,000.

Senior Software Engineer / Algorithmic Trader Freelancer

I'm a highly qualified algorithmic trader and full stack developer offering more than 17 years of in-depth hands-on experience in full life cycle of software development within telecommunication and financial services industries. My ability to overcome complex business challenges in an effective and creative manner, always on time and under budget, and my passion for keeping up with the cutting edge of technologies, will enable me to make a significant difference for achieving the company’s goals. My specialties are algorithmic trading, software development, C++, Python, MATLAB, Java, SQL, erlang, and many more, all of them for the sole purpose of writing masterpieces with zeros and ones which accomplishes what I wanted to implement and beyond, with clean, elegant and effective code.
