A small studio
with deep focus

LenkoLab is a two-person studio based in Coimbra, Portugal. Nadiia Linyvenko, the founder, has been building web and mobile software for more than twenty-five years. Andrii Linyvenko covers backend and mobile development. The studio is small on purpose: the person you write to is the person who builds your system.

Most of that quarter-century was custom work for companies: accounting systems, internal tools, business platforms. Much of it sits under NDA, but some is public. For Printstore Group we built online printing calculators with order placement, a CRM for managing customer orders, and the Paperstore ordering service. They have carried the company's daily work for years, and the director's own words about it are on our home page.

Today LenkoLab is the umbrella for two kinds of work. We build our own products, each solving one narrow business problem: invoicing (Fyntoo Bill), receipt scanning (Fyntoo Scan), field service (Fyntoo Field), inventory (InvoStock), a voice CRM for realtors (Yarna), and FX Diff for Polish accounting. And we take custom projects in the same domains, so the knowledge baked into our apps goes into your system too.

Our engineering taste is deliberately conservative: boring, well-documented technology that will still be maintainable in ten years. We do not bill by the hour; you approve a fixed scope and a fixed price, and you get a finished product on the agreed date. Systems we delivered more than a decade ago are still in daily use, which is the only benchmark of quality we really trust.
