A decade of curiosity,
shaped into craft.

Code, for me, has never been a subject. It has been a language - one I've been quietly writing since childhood.

My journey began in 4th grade - the moment curiosity met possibility. I built my first website, a dojo-themed browser game, in pure HTML, CSS, and JavaScript. That spark never went out.

01 The early years

What started as childhood fascination quickly became a discipline. Through years of self-directed study, I sharpened my command of the web fundamentals and wrote my first Python programs - recreations of classic games like Snake and Pac-Man, built from scratch.

02 High school & hardware

That early curiosity carried me into Hristo Smirnenski High School, where I joined the Applied Programming track and was formally introduced to C# and structured software engineering.

Beyond the classroom, I joined the robotics club and worked hands-on with Arduino, Raspberry Pi, and C/C++ - sparking a lasting interest in embedded systems and the elegant bridge between hardware and code.

03 University & the craft

In 2023, I enrolled at Software University (SoftUni) to formally certify my skills through rigorous, project-based coursework across the full stack. I graduated high school with excellence in 2024 and have continued sharpening my craft ever since.

Today, I'm building a complete full-stack platform for a client - spanning backend, modern frontend, mobile application, and cloud deployment - applying everything I've learned end-to-end.

Now seeking my first professional role as a Junior Full-Stack Developer - ready to contribute, learn, and grow with a forward-thinking engineering team.

16Personalities

ENTP - "The Debater"

Curious, quick-witted, and energized by new ideas. ENTPs thrive at the intersection of possibility and execution - challenging assumptions, sketching solutions, and turning "what if?" into "let's ship it." Which feels about right for someone who's been coding since 4th grade and still finds it the most fun thing in the world.

Years of hands-on time at the intersection of hardware and code - micro-controllers, sensors, servos, real-time logic. The work that gave me a real feel for what's happening underneath the abstraction layers we usually take for granted.

ML Research - End-to-End Pipeline

An end-to-end machine learning research project combining mathematical rigor with production-quality Python engineering - the full pipeline from problem formulation and data collection through model development, evaluation, and deployment. Formally derived the algorithms from first principles: loss functions, gradients, optimization procedures, convergence properties. Implemented multiple approaches from scratch and via established frameworks, with systematic hyperparameter tuning, cross-validation, ablation studies, and significance testing. Modular Python codebase treated as production software. Deliverable is a formal technical report covering theory, methodology, results, and an honest discussion of limitations.
