Hello, I'm Mark Bakos
About Me
I'm a self-taught Software Engineer with a deep curiosity for how things work — and an even deeper drive to build things that matter. Over the past 4 years, I've independently explored and mastered a wide range of technologies, from full-stack web development to AI/ML engineering. Whether its crafting user interfaces, building backend systems, or training deep learning models, I thrive on learning, experimenting, and constantly improving.
I believe that the best software is born from a deep understanding of the user and a relentless focus on technical excellence. Every line of code I write is guided by principles of clean architecture, performance optimization, and accessibility. I'm passionate about creating digital experiences that not only function flawlessly but also delight users.
I value clean, maintainable code, thoughtful UX, and strong engineering principles — I bring a positive attitude, a willingness to dive into the unknown, and a commitment to delivering real value through software.
If there's something I don't know, I learn it. If there's something I can improve, I will. That's the mindset I bring to every project, every collaboration, and every line of code.
