Árpád G.

Vetted Data Science developer in Hungary (UTC+2)

I am a problem solver and a strong believer in interdisciplinarity: one must learn as much of a domain as needed to provide a, correct, maintainable, and robust technical solution to a challenge. I worked in several fields and solved many problems: * Started out as a self-taught iOS app developer in the jailbreaking era. With a few friends, ended up completely re-architecting iCsekk, the top utility bill payment application in Hungary, fixing several high-impact security & logic bugs, also accomodating some idiosincracies of the backend (which we didn't have control over). * Learned Python, JavaScript, shell scripting, and gained an interest in compilers. I eventually implemented my own scripting language, Sparkling. I learned about optimizations, and gained significant hands-on experience with compiler implementation using LLVM. I gave a series of talks at Budapest Swift Meetup on implementing a small, typed language, and a presentation on optimizations at Swift London Meetup. * Wrote my Bachelor's thesis in hardware acceleration of a protein structural alignment method. I implemented the algorithm using HLS in C++ on a Xilinx FPGA, learning the basics of FPGA-based design. * Discovered Rust in 2017 and it quickly became my favorite language. I gained substantial experience with the ecosystem, published a number of libraries, and contributed to the Rust Users forum. * Graduated Summa Cum Laude with an MSc in Data Science from the University of Padua in 2020. Since then, I have been pursing a hybrid data scientist/software architect career at two Hungarian private medical companies, where my tasks range from biostatistical modeling through LaTeX-based template generation to bioinformatics consulting. I hold a C2-level certificate of English proficiency from Cambridge Assessment. I picked up conversational Italian during my 2 years in Padua.
