Piotr Czirnia

I work across the full stack — web, mobile, and data systems. Two active contracts, one degree in progress, eleven years of writing code.


Work

CODEFUSION — Software Engineer (Nov 2025 – present) Custom software house, ~15 years on the market. Working on AI-powered systems including an automated code review platform built on Semantic Kernel. Involved in technical decision-making and client-facing engineering.

DEPCORE — Mid Web Developer (Oct 2023 – present) End-to-end web product delivery at consistent scale. 57+ repositories, 40+ OctoberCMS plugins, 15+ WordPress/WooCommerce implementations, payment gateway integrations (Przelewy24, Tpay), client data migrations and batch processing pipelines. The full lifecycle — consultation, architecture, build, deploy, support.


Stack

Web React, TypeScript, PHP, Node.js, Tailwind CSS

Data & ML work

  • Shipped keyword extraction pipelines to production mailing clientbases
  • Built embedding-based product profiling for user interest inference from browsing and purchase behavior
  • Privately developed a local deep document research harness — crude CLI tool, RAG architecture, running on Qwen and open-source GPT models
  • Batch dataset processing and data migrations for client systems

Architecture is handmade. AI earns its place or it doesn't.
