Distributed RAG Document Synthesis Platform
Containerised retrieval-augmented generation backend. LlamaIndex for chunking and extraction, Qdrant for vector search, and a decoupled MinIO + PostgreSQL storage layer so ingestion never blocks a query.

Systems & Backend
High-Performance HTTP/1.1 Server (webserv)
RFC-compliant HTTP server written from scratch in C++ on POSIX
sockets. A single-threaded, non-blocking event loop over select() holding up
to 1024 concurrent connections, with resumable partial reads and writes.
OS-Level Concurrency: The Dining Philosophers
Classic resource contention solved in C with POSIX threads and fine-grained mutex locking — no deadlock, no livelock, no starvation, and no logging race hiding underneath the result.
Minimalist UNIX Shell (Minishell)
Bash-inspired shell in C: pipes, I/O redirection with heredoc and append, environment expansion, every POSIX builtin, correct signal handling in parent and child contexts, and zero memory leaks.
Raycasting 3D Engine (Cub3D)
DDA-based pseudo-3D renderer in C, in the Wolfenstein lineage. One
ray per screen column, perpendicular wall distance correction against fish-eye,
directional texture mapping, and a fully validating .cub parser.
Mobile & Freelance
Hitspot
Travel discovery app built in Flutter — Google Maps for location pinning, Supabase for the real-time backend, cloud functions for server-side processing, push notifications for re-engagement.
Coeur Clothing
E-commerce app for a Polish premium clothing label — product catalogue, cart management and checkout, built to be operated day to day by people who are not developers.
In Progress
CoreQ — Manufacturing ERP & Automated Quotation
Production management for manufacturing SMEs, migrating a legacy MySQL codebase to PostgreSQL and FastAPI. Bottom-up data model, a virtual machine park of digital twins with live material pricing, and cascading SQL analytics for margin and whale score.
