I am a mobile developer who has worked on Android and iOS applications for 6 years for both large and small companies. I am very passionate about teaching and mentoring and have over 2 years of experience teaching students Java and Python programming, as well as project management.
A decade of hands-on experience, building data-intensive products, and delivering reliable back-ends. I have deployed services used by millions of users, some of the largest companies, and led engineers across EMEA and Asia. Through the bull and bear markets, I learned to make teams extremely effective, moving fast at large scales and large stakes. I also honed my technical skills through various industries and corporate structures, building a breadth of knowledge across databases, Backend stacks, languages and CICD systems.
I'm a skilled developer in a large number of different computer specialties. Can do everything from building and installing servers to programming in more languages than you probably knew exist.

## My Mission First and foremost, I am a technical problem solver. As such, I am a strong believer in the multidisciplinary approach: one must learn about a domain as much as necessary and possible, in order to provide a **correct, maintainable, and robust** solution to the challenge at hand. I find it exceptionally important to work in a way that I can explain my goals, methods, and results to a technical and non-technical audience at the appropriate level, which makes teaching and mentoring an essential part of my toolbox. ## My Experience I worked in several fields and solved many problems, where mentoring, teaching, and public speaking have always been part of the package: * I started my career as a self-taught iOS tweak developer in 2009, during the halcyon days of jailbreaking. With a few coworkers, I ended up completely re-architecting iCsekk, the top utility bill payment application in Hungary, finding and explaining several high-impact security & logic bugs to C-level management. This resulted in a decision of a complete rewrite, which involved fixing bugs, improving maintainability, and accommodating some idiosyncrasies of the backend (which we did not control). * Learned Python, JavaScript, shell scripting, and become interested 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 introduced Sparkling to the general public at Prezi Tech Talks Budapest, then gave a series of talks at Budapest Swift Meetup on implementing a small, typed language, and a presentation on optimizations at Swift London Meetup. * Since my sophomore year, I've been mentoring university students formally (as a teaching assistant and lab instructor) as well as informally, in various formal subjects and broader topics around computer engineering, including: C++, Rust, Python, parallel programming and HPC, linear algebra, calculus, machine learning, and dynamical systems. * 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 development board, learning the basics of FPGA-based design in the process. I presented the results as a paper for the ECCTD conference in 2017 in Catania, Italy, as well as a follow-up talk at Budapest Science Meetup. * Discovered Rust in 2017 and it quickly became my main 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 Typst-based template generation to bioinformatics consulting. I regularly mentored interns and junior team members to improve their coding, algorithm design, and software maintenance skills. During the Covid-19 pandemic, gave an interview about contact tracking methods and applications in the light of mathematical modeling methods. ## Language proficiency - Certificate of **English** proficiency, **level C2,** Cambridge Assessment - Accredited **French** language exam, **level C1,** Budapest University of Technology. - I picked up **conversational-level Italian** during my 2 years in Padua. - My native language is Hungarian.
