Software Engineering +

Hello, my name is Pedro Costa. I am a Senior Software Engineer and a Zend Certified PHP Engineer (Yes, I'm in the yellow pages!) with 14 years of experience in the tech field, during which I have been through quite a few outages, production deploys, tight schedules, bug investigations, and more.

I currently work in the virtual experiences industry as a Senior Software Engineer for Linden Lab, the creator of Second Life. Through my 6 years at the company, I acquired specialized knowledge in working with Payment Service Integrations that support a complex and dynamic virtual economy in Second Life around its own virtual currency, from which I am regularly exposed to the business needs behind fraud detection, digital payments compliance and regulations (PCI-DSS, for example), and handling of sensitive data (PII) abiding to CCPA and GDPR rules. As a Senior engineer I also participate in mentoring of junior engineers, designining and conducting larger system changes, and participating in important cloud infrastructure work.

Previously, I worked as a LAMP Stack Web Developer for Perfect World Entertainment, located in Redwood City, CA, where I maintained RESTful APIs and websites related to the billing platform behind Arc Games ( as well as the company's custom internal ERP software. I also participated in the integration/release of new games, such as Gigantic (PC), Livelock (PC/XBOX/PS4), and console versions for Neverwinter and StarTrek Online.

About Me

Senior Software Engineer and Zend Certified PHP Engineer

I love this field, I love to code, and I have no problem "digging" through legacy code to find answers for current problems. As much as I enjoy regular and personal focused time on code, I am a big team player who is also comfortable with mentoring other engineers and writing quality documentation; taking up on projects that require a great deal of collaboration with other professionals, especially those who don't code; and working closely with QA and Product teams.

I have been working remotely since 2016. Over the years interacting with engineering teams in many different time zones, I learned the pros and cons of remote work. I still enjoy it to this day.

I try to contribute to maintaining a positive and healthy work environment around me, as ways to fight discrimination and harassment. I believe it boosts productivity and help reveal a team's biggest potential when that's out of the way.

Even though it has been quite a journey in Software Engineering already, there are always tons of things that I need to improve on and learn. I am not the most brilliant Software Engineer out there but I am humble to provide the best I can offer from my experience and learn new content from other professionals.
