~15 years
First steps
Console apps in C#. That's when I got hooked on programming and understood that code is simply a way of solving problems.

Hi, I'm
Wojtek.Fullstack &AI Native Developer.
I'm Wojciech Błaszczyk (Wojtek) - full-stack .NET engineer focused on system architecture and AI agents. I build practical IT/tech products and co-founded MaDevo.
The Journey
From zero to hero
Vocational school · Gostyń
Zespół Szkół Zawodowych im. Powstańców Wielkopolskich w Gostyniu - five years from simple programs to full stack, backend, frontend and first larger team projects.
First hackathons
Hackathon runs like BKI Hack, Hacknation Bydgoszcz, Hackyeah Kraków taught me to work under time pressure and ship working prototypes fast.
Larger projects
.NET, React, Python. Full-stack apps, automation and projects with advanced AI.
Poznań Marathon 2025
I ran a full marathon at 18 - it doesn't really connect to my IT story, but it's cool and I wanted to share it.
Project for PSP
Hacknation - Bydgoszcz
Hacknation finalist. With the team we designed a system for the State Fire Service. More in the project archive.
INF.02 / INF.03, matura 2026
Vocational exams & matura
Vocational exams passed with 100%. Solid foundations after years of learning and practice.
MaDevo
Building professional AI agents and software for local business. From idea to a product in customers' hands.
Next Chapter
Next step: Wrocław University of Science and Technology, growing MaDevo and building own products.
Technologies
My tech stack
Enterprise .NET, Python-native AI agents, frontend and DevOps - where I build and what I document in case studies.
Pillar 01
Enterprise .NET & Architecture
Backend architecture - modular monoliths, event-driven design, data under real production load.
[ CORE ]
C#, .NET, ASP.NET Core
[ ARCHITECTURE ]
Clean Architecture, Modular Monolith, CQRS, Event-Driven, Microservices
[ LIBRARIES ]
MediatR, EF Core, FluentValidation, Hangfire, and more
[ DATA ]
PostgreSQL (jsonb), Redis, SQL Server, NoSQL, vector DBs
Pillar 02
AI Native & Agents
Advanced RAG, Python orchestration - not just another prompt-to-API call, but pipelines and evaluation in production.
[ ORCHESTRATION ]
LangGraph, Semantic Kernel
[ FRAMEWORKS ]
LangChain, PydanticAI, FastAPI (Python)
[ INFRASTRUCTURE ]
Vector DB (ChromaDB, PgVector), Graph DB (Neo4j), GraphRAG, RAG pipelines
[ OPS ]
LangSmith, prompt engineering, evaluation
Pillar 03 - (skills from case studies)
Frontend & UX
Same as in the case studies: real UI, not mocks.
- React
- Angular
- TypeScript
- Tailwind CSS
Ship & run
Deployments and cloud for .NET backends and workers.
- Docker
- GitHub Actions
- Azure
- GCP
- Supabase
Quality & contracts
Deliberate testing and APIs meant for integration.
- xUnit
- Integration tests
- REST
- OpenAPI

Beyond the stack
[ HUMAN_SPECIFICATIONS ]
[ HUMAN_SPECS ] · Human parameters
[ SPECS_LOC ]: PL
[ SPECS_AGE ]: 19
[ CORE_DRIVE ]
Software engineering is my tool; solving complex problems is my passion. I don't just write code; I design solutions.
[ PERSISTENCE_LOG ]
Conquering winter peaks and training for marathons at 18 wasn't about the sports. It was about training my mind for long, difficult engineering paths where grit and discipline are the only things that keep you moving. I don't quit.
[ OPTIMIZATION_LOG ]
I am fascinated by business mechanics, product lifecycle, and market validation. Engineering without product value is over-engineering.
[.NET 9][React 18][Supabase][Python][Docker]
I built a technical monster: a modular monolith, a polymorphic notes engine and a custom AI orchestration layer that looked like a post-seed SaaS. This is the story of an ambitious project that aimed to reinvent learning, and instead became my most important lesson in building an MVP.
