Ernest Bieś
Software Engineer // Independent Researcher
I am a Computer Science graduate of the State Higher Vocational School in Tarnów, where I received the Medal for "Outstanding Graduates of PWSZ in Tarnów", awarded by the University Senate. I have been interested in computer science from an early age, and during my education I took part in numerous IT competitions. I am a co-author of the research paper "Metaheuristic Exponential Search Optimization with Covariance Matrix Adaptation (MES-CM)", published in the journal Evolutionary Intelligence by Springer Nature. Today, I focus mainly on building web and mobile applications, while continuously developing my skills in AI-driven development and broadening my engineering knowledge.

Research papers
I like going beyond building applications and seeing how far an ambitious technical idea can be taken. In these projects, I combine programming, algorithm analysis and research work to build solutions that can be implemented, tested, described and eventually presented as scientific publications.
Metaheuristic Exponential Search Optimization with Covariance Matrix Adaptation (MES-CM)
Scientific article published in the journal Evolutionary Intelligence (Springer Nature publishing house) under the title "Metaheuristic Exponential Search Optimization with Covariance Matrix Adaptation (MES-CM)". The work describes a metaheuristic algorithm based on a single solution, combining a dedicated pseudorandom search mechanism with covariance matrix adaptation to steer subsequent iterations toward stronger candidate solutions. The algorithm generates candidate moves over multiple distance scales, balancing local refinement with broader exploration without relying on a population of solutions. The project repository includes both a MEALPY-compatible optimizer and a standalone NumPy-based implementation, making the method easy to test in different experimental setups.

Competitions
Selected competition and conference projects where I combined programming, technical analysis and practical problem-solving. Some of them were presented or recognized by the organizers.
iOS Device Data Extractor
iOS Device Data Extractor is an Autopsy module that creates an encrypted or non-encrypted iOS backup of iPhone and iPad, currently running iOS 10.2 and above. It extracts files from an encrypted or unencrypted iOS backup, including a backup made with iTunes, and can compress them into a ZIP archive for use with the iLEAPP module, for example.
Camera Fingerprint PRNU
Camera Fingerprint PRNU uses photo response non-uniformity of camera sensor (PRNU) to check if a photo was truly taken by a suspected camera or not. Module is not based on metadata such as EXIF, performs a physical analysis of the camera sensor, determines photo response non-uniformity (PRNU), uses the principle that each sensor pixel behaves differently with effects such as non-uniform photo response, making each sensor is unique, identifies each pixel anomaly and uses this information to create a description of the camera sensor - the camera fingerprint.

Personal projects
A full list of my main projects can be found on my GitHub. The projects presented here were created during my education and early professional development, before AI-assisted development tools became widely available. They reflect my foundational engineering skills, learning path, and independent problem-solving at that stage.
