About me

I'm a fullstack web app developer, freelancer, machine learning enthusiast, traveller and technology minimalist currently living and working in Plovdiv, Bulgaria.

Technology skills

NodeJS

Lately, I have mainly been working with NestJS framework.

NextJS

I have been working with React and NextJS for about 4 years. I most commonly use libraries like Tailwind CSS and MUI.

PHP

I have built many projects in PHP, especially in the past. I worked with plain PHP 7 (OOP) and later also with the Symfony framework and Twig template engine.

Python

In Python, I mainly worked on projects involving machine learning, neural networks and data processing in general. I have extensive experience with libraries such as NumPy, scikit-learn, TensorFlow/Keras, Matplotlib, Pillow, or Pandas.

Bash

I have over 10 years of experience working with various Linux distributions. I have also contributed to managing Linux servers on smaller projects and have written deployment scripts in Bash.

SQL

I have worked with relational databases in various PHP and NestJS projects, mainly with MySQL and PostgreSQL. Additionally, I have experience in data architecture and designing databases to align with business and project needs.

Personal projects

I'm a co-founder of Recordica – an app, which helps its users uncover hidden patterns in their daily routine and gain valuable insights. It also provides them detailed reports and statistics about their lifestyle.

Machine learning models to reduce the risks of psychedelics use

This was my diploma thesis (2023) at the Czech University of Life Sciences.

The project applies machine learning to predict and reduce risks in psychedelic experiences using classification models written in Python. It explores theoretical foundations, data processing, model optimization, and evaluation, highlighting the potential applications and future improvements of the developed models.

Regression compressor

One of the final projects of my internship at the University of Évora in Portugal (2022).

This project processes images using a combination of lossy and lossless compression techniques. It applies linear regression to reduce color data, represents similar values with their median, encodes data using a Huffman tree, and includes a decompression algorithm that reconstructs the image.

Drug consumption by personality data

One of the final projects of my internship at the University of Évora in Portugal (2022).

This paper explores the construction of classification models to predict drug use, utilizing various algorithms (Rules, J48, SMO, and NaiveBayes), analyzing factors influencing substance use, and summarizing results while outlining future research possibilities.

Web application for a non-profit organization

This was my bachelor's thesis (2021) at the Czech University of Life Sciences.

This work covers the analysis, design, and implementation of a web application in PHP and JS with a MySQL database for a non-profit organization, including testing, evaluation, and future development suggestions.

Classifier of handwritten digits

The classifier utilizing convolutional neural networks was presented at a workshop of the AI Bridge initiative at the Czech University of Life Sciences. I also created a simple web app working with camera images as a practical example of using an exported prediction model.

Other projects

Some of my other personal projects can be found on my GitHub, although I have a lot of old and outdated stuff there as well.

Projects I contributed to

Unfortunately, not all the projects I have participated in can be published here. I have worked on internal applications for various companies and some projects are still in progress.

Robe websites

I have worked on this project as part of a team at Appio, where I was involved in frontend development (NextJS) and also managed it from a project management perspective.

KineDok

I have worked on this project as part of a team at Appio, where I was involved mainly in frontend (NextJS) development.

Future Bakers

I have worked on this project as part of a team at Appio, where I was involved mainly in backend and frontend development (PHP, Symfony, Twig).

My travels

In addition to many small trips and a study internship in Portugal, in mid-2024 I went on an eight-month trip to Latin America, mainly to Argentina and Chile. You can watch our YouTube videos (in Czech) that document this journey. I have also written a practical travel guide to Easter Island.
