5 articlesPLN 22,000 gross on an employment contract or PLN 170 an hour on B2B? We converted both offers into take-home pay under the tax scale, flat tax and the 12% lump-sum tax — with 2026 social security and health contribution rates, a table of equivalent rates and the costs a B2B calculator does not show.
Gross salary is only the starting point. We calculated, step by step, what one productive hour of a senior developer costs in Poland under an employment contract, a B2B contract and body leasing — with 2026 social security rates, the new labour inspectorate powers and the break-even point of each model.
Most disputes over IT project scope start with a process nobody drew. We show how to describe a business process in BPMN 2.0 so that a vendor can price it: the elements you need, levels of detail, a step-by-step complaint-handling example and how to turn a diagram into requirements.
ITIL is associated with a change advisory board that meets on Tuesdays and a form for everything. ITIL 4 and ITIL (Version 5), released in 2026, look different. We explain what the framework consists of, which practices to adopt first, how to combine it with DevOps and SRE, and when DORA and NIS2 make it no longer optional.
ISTQB has issued more than 1.1 million certifications, yet tech leads still ask whether certification is worth paying for. We map the current ISTQB certification paths, exam formats, 2026 prices in Poland and the business case for a team of eight testers — with every assumption stated openly.
AI writes test cases and clicks through forms, yet companies still hire manual testers. We show how their day-to-day scope has changed, what AI has really taken over, what remains with people, what manual testers earn in Poland and how a Tech Lead should build a QA team around the role.
