Vlada’s career journey is a great example of how curiosity can lead to unexpected opportunities. Starting with a background in Security studies, he decided to explore the fast-growing field of IT, where he found his passion for backend development.
Over time, he mastered APIs, learned how to build scalable systems, and worked with tools like Docker and Kubernetes.
Beyond the code, he’s a fan of Western films and a lifelong learner who knows how to balance the technical with the human side of engineering.
Let’s hear more about his story and the lessons he’s picked up along the way.
What inspired you to shift to a career in IT after graduating from the Faculty of Security Studies?
I realized early on that a long-term career in the security system wasn’t the right path for me. I was eager to explore opportunities in the rapidly growing IT industry, which felt full of potential and innovation. My first step into this field was joining a crypto exchange platform. I initially worked in customer support and later transitioned to API support. This role introduced me to APIs, databases, and SQL. Working closely with these technologies sparked my curiosity and motivated me to learn more about development and DevOps.
Over time, I began to appreciate the impact of technology and saw the incredible opportunities for growth and contribution in this dynamic industry.
Do you see any connections between your academic background in Security studies and your current role in IT?
While my academic background in Security studies might not seem directly related to IT, it has significantly shaped my approach to many aspects of my career. Security extends far beyond physical systems to include digital threats like cybersecurity vulnerabilities, data breaches, and privacy concerns. My studies gave me a solid foundation in risk management, the importance of secure systems, and preventative strategies. These principles align naturally with my focus on development, where I constantly consider the security and reliability of the technologies and systems I work with.
Beyond the technical aspects, Security studies also helped me develop key non-technical skills. Working on projects during my studies taught me how to collaborate effectively, organize tasks, and manage resources – skills that are just as crucial in software development as technical expertise.
Your career journey at BlueGrid has been inspiring, transitioning from API support to Backend Software Development. What were the key differences between these roles, and how did your team support you during this transition?
These two roles are quite different in terms of responsibilities and focus.
As an API Support Engineer, my primary responsibilities involved API testing, understanding the existing codebase, and acting as a bridge between the technical team and our clients.
I spent a lot of time learning how the API worked, troubleshooting client issues, and providing clear explanations to ensure seamless integration with our system.
Transitioning to Backend Software development shifted my focus to the core of the codebase itself. This role is much more technical. It involves tasks like refactoring existing systems, implementing new features, and ensuring the backend is efficient, secure, and scalable. It’s a hands-on role that challenges me to craft solutions that directly enhance the product’s functionality and performance. That is something I find incredibly rewarding.
The team’s support during this transition was invaluable.
They provided mentorship and encouraged me to take on challenging tasks. They also fostered an environment where I felt comfortable asking questions and learning as I went. This collaborative atmosphere made it much easier to bridge the gap between understanding how the API worked and contributing to the development of the systems that power it.
What technical and non-technical skills have you developed that are essential for your role as a Backend Software Engineer?
What I find most interesting about my role is the combination of technical challenges and opportunities to develop critical organizational skills.
On the technical side, I’ve gained a deeper understanding of our codebase, particularly the design and functionality of the API. Working with technologies like Python, Git, and Linux has kept me at the forefront of backend development. Additionally, I’ve honed my skills in tools like Docker, Kubernetes, Ansible, Terraform, and Google Cloud. Each of these plays a vital role in building and maintaining scalable, secure, and efficient systems, which keeps me engaged and motivated to continually improve my expertise.
On the non-technical side, I’ve developed essential organizational and engineering management skills. Collaborating with the team, prioritizing tasks, and managing time effectively have become increasingly important. These skills ensure projects run smoothly, deadlines are met, and the team collaborates efficiently.
How would you describe a typical workday at BlueGrid?
Each day at BlueGrid is dynamic and a mix of technical tasks and collaboration. I usually start by checking Slack for updates, catching up on important conversations, and reviewing new tasks. From there, I prioritize my to-do list based on what needs immediate attention.
My primary focus is backend development, where I work on projects to enhance our code logic, often involving significant refactoring. These efforts ensure our codebase stays efficient, maintainable, and aligned with best practices. I also work on APIs, ensuring they are secure, reliable, and performant.
Throughout the day, I dedicate time to testing, debugging, and identifying areas for improvement, whether in the infrastructure or the code itself. Working with technologies like Docker, Kubernetes, and Google Cloud, I stay current on best practices, which helps enhance our DevOps and deployment processes.
Overall, my workday is a balanced blend of coding, problem-solving, collaboration, and continuous learning, making each day both productive and rewarding.
What tools and technologies do you rely on most in your position?
I use various technologies essential for building efficient, secure, and scalable systems. Primary tools include Python and Flask for backend development and Git for version control.
What do you enjoy most about your role as a Backend Software Engineer?
The best part is the positive and collaborative atmosphere within our team as well as open communication. We work in a relaxed, low-pressure environment, which allows me to focus on coding and solving problems without feeling rushed. My teammates are super supportive and bring so much energy to the table that makes every day enjoyable.
Plus, there’s a great culture of knowledge sharing, where engineers regularly exchange insights and best practices, which makes it easier for everyone to grow and improve.
What advice would you give to someone aspiring to become a Backend Software Engineer?
My advice comes from a quote that resonates deeply with me: “It takes the patience of a saint for counterintelligence.” – James Angleton.
This wisdom aligns closely with backend development, where patience, attention to detail, and the ability to navigate complex, hidden challenges are essential.
In backend development, you’re constantly thinking about how to keep systems stable, secure, and efficient. So, my advice is to start with patience, dive deep into the details, and understand that the learning process is often hidden in the dark – much like intelligence work itself.
If you could switch roles with anyone on your team for a day, who would it be and why?
It would depend on how I interpret the question. If I consider the entire BlueGrid team, I’d be intrigued to take on the role of CFO or COO. I’ve always had a passion for finance and operations, and over the years, I’ve actively worked on improving my knowledge in these areas.
However, if we’re talking about my colleagues on the project specifically, I’d choose to switch roles with an Engineering Manager. I’ve always enjoyed working with people, organizing tasks, and coordinating projects. It would be interesting to test my organizational skills and learn how to balance the many aspects of managing an engineering team.
You’re known for your love of Western films and passion for reading. Could you share one film and one book that you would recommend?
I’d happily recommend Once Upon a Time in the West as my film pick. It’s a masterpiece of the Western genre, featuring stunning visuals, a haunting score, and a story that delves into themes of revenge, progress, and human resilience. It’s a film that lingers in your mind long after you’ve watched it.
For a book, I’d suggest Le Roi du Monde by René Guénon. It offers a timeless perspective to help understand both the past and the modern world.
Lastly, do you have any favorite resources or learning paths that you’d suggest for new developers?
Absolutely! One resource that had a significant impact on my journey is DataCamp. It played a crucial role in helping me land this job while deepening my knowledge of data analytics and data science. Their structured courses and hands-on projects make it an excellent platform for mastering data skills.
For those interested in systems and infrastructure, KodeKloud is another fantastic option. It offers interactive courses on DevOps technologies like Docker, Kubernetes, and Terraform.
I also believe that exploring cybersecurity resources is essential, as secure systems and data protection are increasingly vital in today’s tech landscape.
