During my 4 years of service in the United State Air Force I inspected, tested, troubleshot, and repaired fighter aircraft defensive systems. This position entailed removing & bench checking aircraft electronic modules in addition to maintaining testing equipment (DMM, oscilloscope, signal generator, debug software etc).
Bulk of my work concentrated on isolating electrical and radio frequency malfunctions down to a component level and performing repairs to include frequent soldering.
Freelance and Volunteer Work
I picked up my first programming book (PHP & MySQL) in 2008 — because I was curious to learn about how YouTube worked behind the scenes — and continued to code ever since. In the past 10+ years, I’ve worked on a variety of volunteer and freelance web projects starting with redesign of City of Portland web site (formerly known as portlandonline.com) and followed by many projects over the years.
Between 2012-2015 I’ve maintained a large PHP/SQL code base for three travel websites (wedding-travel.ru, orient-travel.ru, and continental-travel.ru). In 2017-2018 I designed and implemented a Client Management System (CMS), primarily using PHP, for a small business focused on providing chauffeur services to their clients. In addition to standard CMS features (admin panel, database, client cabinet, payment system etc), I’ve streamlined parts of their business by automatically generating required documents in PDF format (receipts, invoices, travel itineraries etc).
