Available for select consulting
Software engineer, 8 years writing production backends in Spring Boot, Python, and on AWS. Currently building the OAuth2/OIDC identity stack at Sanoma and a HealthTech platform with my own startup on the side.
Contact
Open to consulting on AI integration, system architecture, and dev-team enablement. Based in Warsaw, working globally.
Now
Two builds in flight. Both lean on agentic AI as a daily tool, not a buzzword.
Designing and building the OAuth2/OIDC identity provider, BFF layer, and AWS deployment infrastructure for a new generation of learning apps. End-to-end: spec, schematics, Spring Boot code, Helm, Bitbucket pipelines, ALB and CloudFront setup.
Two years in. Spring modulith plus Python services, Keycloak, REST and SOAP integration with legacy government systems, Flutter frontend. Built with extensive AI assistance: agents, openspec, MCP, spec-driven development at every layer.
Helping teams bring AI into their stack without breaking it: agentic workflows, RAG over private data, custom MCPs, and getting devs comfortable with Claude Code, Copilot, and openspec. Selective engagements through RevDev.
Selected work
A subset. The full list lives on GitHub.
Multi-module AI orchestration platform built on Spring AI and Model Context Protocol. Routes per-request to LM Studio, OpenAI, Gemini, Anthropic, and MiniMax. RAG pipeline with Qdrant, semantic memory via Mem0, four custom MCP servers (audio transcription, web search, weather, OCR).
Drop-in template that ships an opinionated agent-coding setup (skills, openspec scaffolds, MCP-ready configs) into any project via git selective checkout. Works across Claude Code, Kilo, OpenCode, Codex.
Cross-platform Ansible playbooks that bootstrap a developer machine on Linux, macOS, or Windows in minutes. Idempotent, declarative, data-driven OS dispatch.
Migrates Zigbee devices between Home Assistant integrations without re-pairing. Solves a real pain point for self-hosted smart home owners.
Custom addressable-LED controller and receiver designed in KiCad with AI assistance via MCP. Schematic, layout, fab-ready board, all with the AI in the loop alongside the usual tooling.
Smart airsoft target with ESP8266 firmware, piezo hit detection, Flutter mobile app, and a Wi-Fi web interface. Local Wi-Fi AP, no cloud, sub-100 ms latency.
Cross-platform GUI for cleaning, categorizing, and labeling personal transaction CSVs. Ships as a Windows installer, Debian package, and snap.
Experience
Mechanical engineering at Gdansk Tech with an Erasmus year in Rome, then the last eight years on backend systems. Mobile, desktop, web, embedded.
Skills
Grouped by domain. No proficiency bars; everything here I've shipped to production.
Qualifications
Mechanical-engineering background, Erasmus exchange in Rome, then a pivot to software via Java bootcamp.
Consulting
Three things I do well, available as advisory, audit, or hands-on engagement. Engagements run through RevDev.
Eight years writing backends in Spring Boot, Python, and on AWS. Greenfield builds, rewrites of older services, OAuth2/OIDC, REST and SOAP, deployment automation. The base under everything below.
Pay down tech debt, redesign older backends, move legacy code to Spring Boot or to a sane Python service. OAuth2/OIDC, AWS, Helm, deployment that holds up under load.
Plan the agentic workflow, set up RAG over private data, ship MCPs for your tools. Designed for places where security and operations review every change.
Onboard your devs to Claude Code, Copilot, and Codex with shared agent-standards, project skills, and MCP setups. Ship faster without losing quality.
