  E-commerce platforms for luxury car brands and dealers.

  • Senior full-stack engineer (September 2020—April 2023)

    An interim stand-in for my manager, who went on maternity leave.
  • Full-stack engineer (May 2019—March 2020)

  • I created a preorder Stripe-based platform for a high-profile car model launch, that sold out in under 10 minutes after going live.
  • I maintained a fleet of existing projects and delivered new features.
  • I optimized principal areas of several key products.
  • I held code ownership of a web platform for one of the customer brands.
  • I achieved a bug-free backlog in one of the company's bigger projects.

  Decernis (Food and beverage, U.S.)

  Supply chain management and compliance solutions for American and European food markets.

  • Senior technical team lead (November 2019—January 2021)
  • Senior full-stack engineer (April 2019—October 2019)
  • Regular full-stack engineer (April 2018—March 2019)

  • I maintained several key products, steadily expanding my expertise to eventually become a team lead.
  • As a team lead, I conducted a complex migration project to shift away from a legacy LDAP solution to a relational database, which fundamentally involved the entirety of the client's products portfolio. This endeavor reduced synchronization issues across the board that plagued the previous system, improved the client's relationship with their customers and allowed to implement a _single sign-on_ function.
  • I ported the codebase from Python 2 to Python 3, which improved code maintainability and product performance.
  • I introduced Docker containerization, which eased onboarding and development workflow for new employees.
  • When I was a team lead, the team grew from 2 people to 7.
• Career change to Python

  The years of experience with Python in non-commercial projects have allowed me to appreciate how rich its package ecosystem is and how quickly one can prototype various solutions with it. These observations eventually led to a natural decision to closely tie my further professional path to this technology.
