CTO | Senior Software Developer | Full-stack, Ruby on Rails
$95.00/hr
Given my 20+ years of experience as a top level competitive programmer, algorithm designer, tech lead, and CTO, I am confident that I am one of the best software engineers you will find on Upwork. Additionally, I have extensive experience in startups, recruiting, training, as well as marketing and SEO, and I screen for projects where I know I can make the highest impact on a company.
The following is a brief overview of my relevant technical experience:
✔ CTO, Tech lead (17 years)
✔ Ruby on Rails (12 years)
✔ MySQL (23 years)
✔ PostgreSQL (12 years)
✔ Javascript (23 years)
✔ jQuery (10 years)
✔ React (5 years)
✔ Python (5 years)
✔ F# (5 years)
✔ PHP, CSS, HTML (23 years)
✔ Linux administration (23 years)
✔ Deep Learning / Machine Learning / Data Science (3 years)
The highlight of my career was my work as Chief Technology Officer for Five Digit Media Inc., an internet company I had an immediate significant impact on after joining in March of 2005. I was already an expert software engineer, but during the six years I spent as CTO I learned a lot about effective teamwork, leadership, and what it takes to run a successful IT business, particularly in the aftermath of the company's 10x growth.
Over the next year, I would like to sharpen my skills further while contributing to the best companies that Upwork has to offer.
I have hired and managed top talent myself, so I understand the employer's perspective well, and what is expected of an exceptional tech professional.
