My name is Alek and I'm a Computer Science student at University of Warsaw in Poland 🇵🇱 pursuing my Master's degree. Since primary school, programming has been my passion and hobby. In my spare time, I like to focus on my private projects and learn new technologies. I like to think about myself as a full-stack engineer. I have an experience in both creating frontend applications in Django, Angular or WordPress, but also writing libraries and programs in Java, C, C++, Rust, Kotlin, Python, JS, TS, Assembly, OCaml, Haskell or even Prolog. New challenges are my fuel, and I can't wait to solve new problems!

My area of interest are numerical methods, including numerical analysis and computer graphics. My first numerical algorithms were created using Matlab/Octave, but currently I work mostly in Python (numpy/scikit) and C (for OpenGL). I intend to learn Julia in the near future.

• In October 2025 I joined RTB House, Core Engineering team as a distributed systems engineer.

• Starting from summer 2023 I was a Software Engineer (Analyst) at Goldman Sachs in Risk Division until September 2025.

  • Full stack engineer - Java / React
  • Worked with cluster computing and big data.

• During summer 2022 I was a Software Engineer intern at Goldman Sachs in Risk Division.

  • Collecting Prometheus metrics, building Grafana dashboards, defining SLOs and alerts for Credit Risk Infrastructure.
  • Integrating existing services with SRE architecture.

• During the second year of my studies I was a part of SIO2 project which is a programming contest platform. I was responsible for developing new features and fixing bugs. My main focus was on the infrastructure of the project. My main accomplishments are:

  • I participated in architecture migration to GitHub from local Gerrit instance
  • I created GitHub Action automation workflows based on local Hudson instance
  • Django migration to latest LTS (2.2.25 -> 3.2)
  • I introduced e2e testing framework Cypress
  • Minor bug fixes
  • Check out my contributions

• For three years I was a participant of Summer IT Workshops organized by my High School. We were solving programming problems and learning new algorithms and data structures. All the problems were solved using C/C++ code and Bash scripts.

• In 2017 I started to interest in Olympic programming. I participated in the Polish Olympiad in Informatics for Junior High Schools and I was able to reach the final round. I also participated in Polish Olympiad in Informatics for High Schools, but I lost interest in this competition.

• In 2016 I was asked to develop and maintain my school's webpage. I was using Wordpress and PHP to meet the expectations. Although the page is deprecated you can still access it at https://gim.staszic.waw.pl/.

• Master's thesis - Lindenmayer systems, Computer Graphics and Parallel Computing. TBA...

• Kava org - I'm a member of Kava org which is a group of students from University of Warsaw. We are working on a project which is a Java framework for web applications. We create common tools from scratch to learn advanced Java concepts as a part of the academic course. I work personally on Servlet Container Arabica and Logger Lungo module.
• Just Pure 2D Graphics Matrix Display - Powerful matrix calculator with LaTeX support written in Rust.
• Bachelor's Thesis Intern at JetBrains - Support for Rust targets in Build Server for Bazel. Our goal is to integrate rules_rust with Bazel-BSP and IntelliJ IDEA.
• Jabba the Lang - Interpreted imperative programming language written in Haskell.
• Latte - A llvm-based compiler for a simple imperative programming language written in Haskell.

• Computer graphics - I'm learning how to create 3D scenes using OpenGL and GLSL as a part of my Master's program.
• Lindenmayer systems - I'm learning how to create fractals using L-systems by leveraging OpenGL and GLSL as a part of my Master's Thesis.
• HPC - I'm taking part in HPC class during my Master's studies. Working both with CUDA (shared memory model) and MPI (latency-bandwidth model).
• Big Data - I'm taking part in Big Data class during my Master's studies. It involves Spark, HDFS and lot's of theory.

• LinkedIn
• mail

Do not be afraid to ask me about anything!

• Java, Kotlin, Python, C, C++, Haskell, OCaml, Rust, Bash, SQL, HTML, CSS, JavaScript, TypeScript, CUDA
• Android, DataBases (Oracle, PostgreSQL, MySQL), Spark, HDFS, Docker, Bazel, Maven, Gradle, Spark, HDFS, GCloud compute, MPI
• Git, SVN, GitHub, Jira, Prometheus, Grafana, Miro, OBS, JetBrains tools, Linux (UNIX) systems, Windows
