Błażej Porwoł

Solutions architect and developer in Warsaw. Eighteen years building business-critical systems for banks, EU agencies and enterprise clients - now working mostly in Python on retrieval, LLM tooling and system integration.

Founder of RisiTech, an independent studio for system integration, business process automation and AI solutions.

A RAG stack, built in the open

Three tools that compose into one pipeline - ingestion, retrieval, reasoning.

Project
textractor Structure-aware markdown extraction from PDF, DOCX, PPTX, HTML and EPUB. Chunks on heading boundaries instead of splitting mid-paragraph, with optional OCR and image captioning.
hygrep Self-hosted semantic code search. Vector similarity over LanceDB combined with SQLite FTS5 full-text, so exact-symbol and conceptual queries work from one interface. FastAPI service plus CLI.
deep-research-agent Multi-agent research pipeline: a supervisor dispatches parallel researchers, then draft → critique → revise until quality converges. LangGraph and FastAPI with a Go CLI client. Built on top of Fareed Khan's original notebook.

Agent infrastructure

Project
mcp-relay Routing proxy that puts many Model Context Protocol servers behind a single endpoint, so a client reasons over a manageable tool surface.
MUMA-Mem Layered memory for multi-agent systems - ACT-R activation scoring, Ebbinghaus decay, Zettelkasten-style linking, and nightly consolidation from episodes into durable knowledge.
soulgen Visual wizard for designing agent personalities, generating the identity files an agent runs on. Live demo

Also

  • reddit-research - question answering with Reddit discussions as evidence; ships an MCP server
  • dict-ai - Windows voice dictation on .NET 8, hybrid Whisper transcription with provider fallback
  • proscraper - SerpAPI-backed scraping CLI with SQLite persistence and batch mode
