Hi, I'm
Fullstack Developer · Web & Security
Web/full-stack with an infrastructure and security background. Java/Spring, React/Next.js and Python/FastAPI - web apps and REST APIs, on Azure, in Docker, built with OWASP and WCAG in mind.
Fullstack Developer with 3+ years of commercial IT experience - from ERP rollouts and server administration, through QA, to building production web applications. I currently work as a developer at the Auschwitz-Birkenau State Museum (accessibility audits and security testing of web applications). I build web apps and REST APIs and work with the cloud, containers and relational databases - the full tech stack is listed below. The infrastructure and cybersecurity background (a Master's degree in progress, hands-on SIEM and hardening) isn't a separate track for me - it's how I approach writing applications. I'm fluent with AI tools (incl. Claude Code, Codex) for building apps, bots and automations - from planning and documentation, through code, to deployment. I've conducted two digital accessibility audits (WCAG 2.2 AA); I also build WordPress/WooCommerce sites and shops.
Web/full-stack with an infrastructure and security background - the stack I actually use
Selected apps and deployments
A commercial SaaS running in production for a children's play-centre business: a customer web app and an admin panel. Also available as a mobile app (iOS/Android).
A bilingual WordPress site (~50 pages) for the Visitor Service Center of the Auschwitz-Birkenau State Museum.
Online voting for the “Angelusy 2026” contest (Słomniki municipality): multiple categories, live ranking, admin panel.
A cooking platform built on user-generated content, live on its own domain: recipes added, rated and commented on by users, moderation, badges, a meal planner. Next.js 16, with SEO as the primary goal.
A meal ordering and billing system for hospitals, schools, offices and companies: menus, sign-ups with cut-off times, monthly billing and serving lists. A single Go binary serves both the API and the embedded React UI.
A full-stack property-rental platform (Airbnb clone) with a Java/Spring Boot backend: REST API, map search, bookings and tenant/landlord panels.
An in-house web application security testing (DAST) automation platform in Go: it orchestrates external scanners and its own modules, maps findings to OWASP Top 10, ASVS and WSTG, and generates reports. I used it to test my own sites (portfolio, CV, KucharKi) and hardened them based on the findings.
A custom Discord bot keeping order on the MAKO server (~3000 members): role-ping moderation with exempt lists. Built, deployed, hosted and iterated on at the client's request.
A Discord bot tracking product prices in online shops: on-demand and scheduled checks, price history, thresholds and price-drop alerts. Products and sources are configured with a plain DM - no code changes, no restart.
A Discord bot alerting about free driving-test slots: mObywatel sign-in from a DM (Playwright), checks across several exam centres within the portal's rate limits. Running in production.
An app for organizing potluck-style get-togethers - participants declare who brings what (food, drinks, extras), share photos and videos from the event, and a summary shows everyone's contribution. No more chaos in the group chat.
Engineering project: a scalable SIEM architecture (ELK Stack + Wazuh) for collecting, normalizing and visualizing logs and detecting incidents in real time.
Engineering thesis: comparative performance analysis of 6 database engines (SQL vs NoSQL) for a SIEM architecture - writes and analytical queries over 1M records across 50+ scenarios.
