I'm Vladimir Lazarenko

I'm a technologist

and . . .

I love IT engineering :)

Bio Pic

I'm very passionate for engineering and engineering culture. Building teams that empower companies to deliver business value through efficient technology is what makes me tick. I am all about continuous improvement, challenging status quo and pushing the boundaries of “the usual”. Huge fan of keeping complex solutions simple, understandable and accessible. Strong Dev(Sec)Ops movement advocate. Experienced in helping large multinational companies transition from waterfall models to true DevOps.

I have a keen interest in evolving company culture, not hiring a "DevOps team" and claiming that transformation is done.

I've worked in different countries & met lot of people throughout my professional life. Earned friendship, respect & trust. Therefore I got some achievements to share.


Agile transformation @Marktplaats

Participated in a global agile transformation of Marktplaats (part of eBay Classifieds Group), where we went from classic "dev toss to ops" approach to cross-functional teams, increased release cadence from bi-weekly to hundreds a week, moving from PHP codebase to a scalable scheduled micro-service architecture.


Mobile app development business

Together with a business partner we've built and ran a mobile app development business at the time where it was all very new. Grew the company from 2 shareholders to over 50 developers. Were part of the early mobile app adoption time. Worked on first apps with Rabobank, AJAX, Interpolis to name a few.


Awesome team @ eCG

Helped build, form and lead one of the strongest DevOps engineering teams in the country. Super proud of what we have achieved, even more proud that the team is going strong after I've decided to split. Miss you guys!


Cloud journey @FedEx Express

Introduction of scalable and resilient cloud-based platforms, powering TNT (will become FedEx Express) and FedEx. Modernization of legacy applications, evolvement in ways of working, indoctrination and scaling of DevSecOps culture in one of the largest enterprises in the world.


Aside of the fact that I've attended schools and courses, my main learnings are always on the job. Nevertheless, here are a few things that did get me a shiny paper.

  • HashiCorp Certified Terraform Associate, Apr 2020

    Exactly what the title says. Verify here.

  • Scrum Alliance Certified Scrum Master, Oct 2010

    Successfully passed the course and the exam. Have used the skills and techniques frequently in various teams adjusting the framework as needed to get the maximum added value for the team with minimum bureaucracy.

  • Rational Unified Process, 2007

    A framework that was popular at the time :)

  • Kharkov's Radio Electronics University, 1997-2001

    We've all been to high-school at some point...


I have worked with a lot of very smart, skilled and generally wonderful people over the years. Here is what they got to say about me.

Technology leader at eBay

David Campbell

Vladimir is one of the strongest full stack system engineers it’s been my pleasure to work with. He is able to provide technical leadership on everything from low level systems to writing code. Vladimir has a great ability to learn the newest technologies such as containers and cloud whilst retaining total understanding the fundamentals. He provides great leadership to his team and is the go to person for many things. Great leader, great engineer and great colleague.

Director of Software at Northvolt

Arne Bultman

In my 6 years of working with Vladimir I've come to know him as a no-nonsense person that likes to get things done and will do everything in his power to get there. A strong technical skillset allows him to both deal with ongoing operational concerns while working towards a long term strategy. Working with Vladimir has been a pleasure and I'd have no hesitation working with him again in the future.

Transforming payments at Uber

Özgen Güngör

Working with Vladimir is a great experience. He is extremely knowledgeable about architecting scalable infrastructure (cloud or otherwise), networking, and developer tooling. He has strong technical skills and excellent problem solving capabilities supported by years of experience and sharp situational awareness. What makes it so great to work with him is his honest and direct communication and strong drive to get things to the finish line.

Principal Engineer at Norhvolt

Frank Schröder

I've worked with Vladimir for five years at eBay where he ran the SiteOps infrastructure and later the team. He is a no-nonsense person who is focussed on solving the immediate problem and then finds a long-term solution. He always had in-depth knowledge of all of our platforms around the globe and was the first person I've turned to for architecture advise. He is a great person and if you have a large scale infrastructure setup then Vladimir is your man. I'd hire or work with him again without hesitation.

Manager Operations at iWelcome

Arnold Leendeers

Some people you never forget and Vladimir is one of them. A very well skilled person with the brains, drive and creativity to make a change. He contributed significantly to our deployment process improvements, making complex configurations user-friendly.

Head of Business IT Global Infrastructure at OLX Group

Milton Cyrus

I have had the pleasure of working with Vladimir for 8 years. He is one of the best engineers and engineering leaders I have worked with. Vlad has an amazing ability to learn and apply the latest technologies and has a firm understanding of the fundamentals. Vlad is a great addition to any team, as a person, engineer and technical leader.
