The-worst.dev is….
Hi there — I’m Patryk Roguszewski, a Polish-born (1994) software engineer who still loves the thrill of turning ideas into working code.
I shipped my first scripts back in 2006 while hacking together custom PAWN mods for a self-hosted GTA San Andreas Multiplayer server, and I’ve been hooked ever since. Eight years later I turned that hobby into a career and haven’t looked back.
I code (and speak) with a pragmatic-first mindset—think small, frequent releases that solve real problems instead of gold-plated abstractions—an outlook inspired by classics like The Pragmatic Programmer and its “ship value early” mantra. In practice, that means choosing the simplest tool that works, favouring feedback loops over heavy upfront design, and always budgeting time for refactoring so the codebase stays change-friendly.
I had the pleasure of sharing my software development knowledge at big Polish conferences:
- Infoshare 2022 – web3 in backend development,
- Boiling Frogs 2024 – tech agnostic in microservices architecture – hot or not?
What I Do Today
- .NET Framework / .NET Core — C#, Web API, background services,
- Angular & Flutter — responsive front-ends and cross-platform mobile apps,
- SQL Server & PostgreSQL — data modeling, performance tuning,
- DevOps & Cloud Cost-Optimization — CI/CD, infrastructure as code, monitoring,
- Software Architecture & Code Review — from green-field sketches to legacy refactors,
- Vibe Coding – improving code development performance and quality over Cursor, Bolt, and other AI-related developer tools,
- AI – engineering tools (Langfuse), LLMs & Models (OpenAi, Perplexity) and SDKs (Semantic Kernel, Open AI Agents SDK),
- Consulting, mentoring, workshops.
How I work
I’m a believer in pragmatic software development, lightweight documentation, automated processes, and knowledge sharing. Every lesson that sticks goes into my Evernote vault, which grew into the-worst.dev — a blog where I publish deep-dive tutorials and, frankly, practise my English. Spot a grammar crime? Let me know!
Outside the IDE
When the laptop closes, you’ll find me:
- Deadlifting or swimming laps
- Testing keto-friendly recipes
- Reading everything from economics to sci-fi
- Trading (both traditional and crypto markets)
- Replaying Heroes of Might & Magic III for the hundredth time
