Hello I'm Piotr Jeleniewicz

ENGINEERING STUDENT BASED IN POLAND

As a passionate engineering student interested in technology and electronics, I thrive on learning new things and developing my technical skills.

About Me

A Visual Journey through my Portfolio

I am an engineering student interested in technology and electronics. I like to learn new things and develop my technical skills. I have experience in design and programming. I am active, committed, and able to work under time pressure. I quickly absorb new information.

Core Strengths

From Circuits to Code

Electronics and Simulations

Practical knowledge of electronic components, operation of measuring instruments (confirmed by laboratories). Operation of software for design and electronic simulation: Micro-Cap, LTspice, Falstad, EAGLE, Vivado. Knowledge of control theory (system analysis, simulation, modeling).

service
Programming and Engineering Fundamentals

Experience in programming (C++, JS) and implementation of various technical projects. Solid theoretical foundations in mathematics and physics, key in the technical fields.

IT Tools and Systems

Ability to automate tasks (AutoHotkey), proficient in Visual Studio Code. Management of virtual machines (VMware, VirtualBox) and configuration of operating systems.

MY Skills

Crafting Ideas Building Dreams My Creative Portfolio

2023 - present
Gdańsk University of Technology

Electronics and Telecommunications, 3 year

I am an active member of the 'Simle' student research circle. It's a fantastic experience where I am part of an awesome team working on an ambitious project: building a fully functional radiotelescope. This hands-on work is an incredible opportunity to apply my engineering studies to a real-world challenge, and I am thrilled to be a part of it.

My Projects

Things I Have Built

01 / Java Desktop Game

LabInc: Chemical Tycoon

Completed

An educational strategy game combining incremental/idle mechanics with chemistry. You start with a simple coal mine and grow a production empire of 16 factories - all the way to a nuclear reactor producing synthetic elements.

  • All 118 chemical elements to produce and sell - from carbon to oganesson
  • Exponential economy scaling from $0.01 up to $1035
  • 18 achievements plus automatic and manual game saves
  • Custom dark Swing GUI - Mining, Factories, Market and Achievements panels, animated effects and sound
Java 8+ Swing Maven JNA Batik (SVG) MP3SPI
LabInc: Chemical Tycoon - mining panel with coal mine and oil derrick
02 / Data & AI Tool

Job Search Aggregator

In development

A tool that hunts for jobs so I don't have to. It scrapes offers from major job portals, merges them into a single ranked list and then investigates the most promising ones in depth.

  • Aggregates offers from multiple job portals into one list
  • Filtering per provider or globally, with ranked results
  • Deep Research stage (Gemini API): company profile, GoWork/Glassdoor reputation, salary vs. market median, work mode, the actual tech stack and benefits
  • Red-flag detection - planned layoffs, complex reporting structures, organizational silos

03 / Cross-platform App

Password Manager

In development

A simple cross-platform password manager developed as a group project - one lightweight vault that behaves the same on Windows and Linux.

  • Runs natively on Windows and Linux
  • Built by a small student team as a group project
Windows Linux Cross-platform
Side Projects

More of My Work

Yaper

Windows desktop app for speech-to-text transcription with two push-to-talk channels and switchable offline/online transcription engines.

Windows Push-to-talk Offline/Online

Radio Telescope Control Panel

Frontend and backend control panel for the SimLE student research club's 3 m radio telescope - remote control, tracking and monitoring in a single interface.

Frontend Backend

Florist Website

In development

Website for a local florist - a real client project, built as a small team.

Web Client project

BlackBox

Simple terminal-based logic game written in C++ - find the hidden boxes by shooting rays and interpreting how they deflect.

C++

Stock Market Analysis Tool

Terminal application written in C++ that parses stock market data and draws bar charts directly in the console.

C++

Game Inventory Generator

Visual video game inventory generator - a web tool that builds a Minecraft-style inventory from a searchable item database, with configurable slots and amounts.

About Me

About me

My name is Piotr. I study Electronics and Telecommunications at Gdańsk University of Technology (WETI), currently in my 6th semester on the Computer Electronic Systems profile. What drives me most is automation - building bullet-proof setups that keep working reliably across different systems.

What keeps me busy right now:

  • Engineering thesis - teaching a reinforcement-learning agent (PPO/DQN) to master an arcade game on its own
  • SimLE research club - lead software developer of a 3 m radio telescope: remote-control web app, star targeting and tracking, SDR data analysis
  • Personal projects - a job search aggregator, this portfolio and a few websites built for real clients
  • Math tutoring - from primary school up to advanced high-school level

After hours you'll find me diving (Open Water Diver), playing guitar and going to concerts, experimenting with computer graphics and AI tools, or at the gym and on the bike.
