About Berta Matu - Software Engineer
Berta Matuliauskiene
FROM SELF-TAUGHT TO TECH LEAD IN LESS THAN 6 YEARS
Skills can be taught, but attitude can’t!I firmly believe that technical skills can be taught, but attitude and curiosity cannot. This mindset guided my transition from finance into software engineering, where I’ve grown from writing my first lines of HTML to working on large-scale systems as I step into a Tech Lead role within less than 6 years.
I focus on delivering practical, maintainable solutions-favoring clarity and simplicity over unnecessary complexity, and improving existing systems where possible. I aim to contribute not only through code, but also through mentorship and technical direction, supporting both team growth and delivery outcomes.
Outside of leading architectural work, I explore prompt engineering and continue developing my interest in iOS development.
Beyond the Code
Tech Content Creator
Just after finishing my studies, COVID hit and everything closed. To keep moving toward my software engineering career, I turned to Instagram to network with developers. Sharing my daily goals, losses, and project portfolio, I slowly built a supportive space over the years. Today, I've cultivated an incredible community of over 120k+ people. I deeply enjoy sharing my developer's journey, helping, and motivating others because I know exactly how much support is needed to survive and thrive as a self-taught engineer.
Lecturer & Mentor
Mentored for the Product development project module, which brought together researchers, lecturers, and student teams to develop prototypes from ideas. Provided deep technical consulting to teams.
- Scrum methodology workshop.
- Client/User voice survey questionnaire research workshop.
- Tech advice regarding UI solutions and Agile/Scrum.
- Mentoring.
Public Speaker & Mentor
In partnership with this organization, I had the privilege to visit schools across Lithuania. During these visits, I spoke to students about the tech industry, software engineering, and the startup ecosystem, with the goal of encouraging the next generation to be brave, creative, and endlessly curious about tech.

How It Started
- In 2019 I've started to learn Front-end engineering fundamentals and built my very first simple website in a week!
- In 2020 January I finished full-stack studies at the Baltic Institute of Technology - was one of the most driven students. I was a self-taught front-end enthusiast, so I mentored my classmates and other students at coding school with our daily tasks and homework during scrum classes in the front-end development module. During the studies, we also got familiar with OOP and Java fundamentals. My final project was a web CRUD app , built with Spring Boot and MySQL. I enjoyed working on the front-end part and I already was self-taught in some front-tend technologies, so I decided to focus on it after getting my diploma.
