Sr. Software Engineer, a 14 Year Career

Matt Roszyk - Sr. PHP Developer - Backend Data Architect

For the last 14 years I have been actively researching and creating software for a wide range of applications both very small and very large. My goal is to continue creating refined, efficient, scalable, and maintainable solutions to the most challenging problems I come across.

I am currently contributing to the Open Source project BlazePHP, a very light weight framework designed for use in large distributed backend systems. This is a product from years of research, trial, and error.

Engineering solutions is not only my passion in the virtual world of code. I also enjoy working with my hands in a very real three dimensions, both in wood and metal.

Originally I was hired to design and build the next generation platform for Singlesnet.com using PHP and MySQL. The high demand of 30,000 concurrent users was breaking the limits of the current platform.

For the past year and a half I have been maintaining parts of that code base and upgrading several of the core components including billing and search.

Projects & responsibilities:

  • Worked directly with our Sr. MySQL database engineer to design, build, test, and benchmark the new search platform using a distributed method to reduce disc usage and gain performance.
  • Create, upgrade, and maintain cron scripts pertaining to billing, rebilling, and search data.
  • Benchmark various aspects of the code base to find performance bottlenecks and develop faster ways to solve these problems.
  • SQL benchmarking for new features to ensure a minimal impact on the site performance.
  • Designed with my esteemed colleague and built the new platform for Singlesnet.com managing two developers.

Freelance is more like it. I would say these are my developmental years as most of it was spent working side jobs for next to nothing or as a favor. The most significant project that I worked on during these years was for an industrial supplier in Buffalo NY. I created a commercial website using Authorize.net as the processor. Later on they started doing a lot of business with Ebay so I made a checkout system that worked with Ebay and also a way to automate the creation of ads from the site's database of tools and supplies.

Projects & responsibilities:

  • Created a complete e-commerce site that interfaced with Ebay and Yahoo auctions
  • Automating general office tasks using Perl
  • Created the packing and invoice system for the warehouse at http://www.soldiercity.com/
  • A boat load of late nights trying to figure out the next technology I could get my hands on.
