I build automation, integrations and AI systems for B2B companies.

I deliver data pipelines, web scraping, app deployments and custom AI agentic systems, all built for production on the tools your company already uses.

  • Systems that run every day, not slide decks
  • Built on the tools your company already uses
  • Shipped to production, then maintained

Describe the process briefly. I'll come back with a concrete approach and a quote. No fluff.

Some of the technologies I work with — chosen for production and maintenance, not for hype.

What I actually deliver

Four areas where I build working solutions in production, not slide decks but systems that run every day.

  • Custom order email → CRM/ERP → MRP → delivery tracking: a new manufacturing order arrives by email, gets parsed into the CRM/ERP, internal production orders are assigned in the MRP system, and the whole manufacturing & shipping process is tracked end-to-end
  • Order → invoice → accounting → onboarding: a full quote-to-cash flow with zero manual data entry
  • Joining data across systems: product, support, CRM and payments in one measurable place
  • Public tender & registry monitoring: tracking changes and new listings that match your profile
  • Structured data extraction from public sources: automatic retrieval, validation and normalization
  • Competitor e-commerce price monitoring: real-time tracking of price changes
  • Company database + contact enrichment: extracting and enriching records for your CRM
  • AI-powered analysis of posts on X (Twitter): monitoring topics, sentiment and buying signals
  • Custom applications built from scratch: internal tools, dashboards, portals and workflow apps tailored to your process
  • Custom development for your needs: features and modules off-the-shelf SaaS doesn't have
  • HubSpot / Salesforce → Open Mercato saves €7–25k/yr
  • Shopify Plus → MedusaJS saves ~€25k/yr
  • Data migration with full history: customers, transactions and documents preserved
  • Agentic systems: AI agents that connect to your tools and workflows and perform tasks automatically across them, reading, deciding and acting without manual steps
  • Visual hyper-personalization: a system that scrapes a prospect's brand assets (logo, colors, fonts), renders your product in their visual identity, and generates personalized landing pages + mockups for outreach campaigns
  • Document digitization (OCR + AI): extracting data from invoices, contracts and forms: recognizing fields (tax ID, amounts, dates, line items), validating, and automatically writing to your CRM, accounting or database
  • AI automation tailored to your company: models and agents integrated with the tools your team already uses
Comparison

What changes once it's automated

Most of the work I replace isn't complicated, it's just repetitive: copying data between systems, checking the same pages, retyping the same fields. Here's the difference in an ordinary week.

Same Monday, two different companies:

Manual today

  • Someone retypes orders from email into the CRM and ERP.
  • Competitor prices and tenders are checked by hand, when there's time.
  • Product, support, CRM and payments data live in separate tools.
  • SaaS licences grow every year whether you use them or not.

Automated with me

  • Orders flow from email to CRM/ERP to MRP with zero manual entry.
  • Prices, tenders and registries are monitored automatically, with alerts.
  • The data is joined in one measurable place you can actually report on.
  • Open-source alternatives replace the licences you're overpaying for.

Frequently asked questions

Short answers to the questions I hear most often.

No. I build on the tools your company already uses and connect them through REST APIs and SQL databases. Replacing a tool is only on the table when the licence cost clearly outweighs the migration, as with the HubSpot or Shopify Plus migrations above.

Tell me briefly what you'd like to automate or build. I'll come back with a concrete approach and a quote. If the scope isn't clear yet, we start with a consultation: a process audit, solution architecture and an automation roadmap before any implementation begins.

Whatever you need. A project can end at the agreed deliverable, or continue as a retainer: maintenance, improvements and new automations as your needs evolve. These are systems that run every day, so they get looked after.

Whichever fits your stack and your problem: Anthropic, Gemini, Hugging Face or Vertex AI. The choice follows the requirements, not the hype. What I build are custom solutions, not off-the-shelf wrappers.

Yes. I'm based in Wrocław and take remote projects across Poland and the EU. Polish is native, English is C1 after 2+ years living in London.

Yes, with full history: customers, transactions and documents are preserved. Data migration is part of every deployment and replacement project I take on.
