Our journey
The beginning
Started professional software development. First contributions to open source, first enterprise projects in .NET and SharePoint.
Enterprise scale
Part of a company that scaled from 5 to 50+ engineers. Delivered financial systems for major Polish banks, learned what it takes to ship software at scale.
Own products
Started building SaaS products for e-commerce and agencies. Panel Pro and FBA MultiTool launched on Chrome Web Store. FBA MultiTool acquired in 2026. Became a CRXJS maintainer.
Optymized
Founded Optymized — combining enterprise delivery experience with product development. A company that builds software and builds products, reinforcing both.
How we work
These aren't values on a wall. They're how we actually operate, every project, every week.
Product-minded engineering
We don't just write code to spec. We question requirements, suggest better solutions, and think about the end user at every step.
We build what we sell
Our own SaaS products (Panel Pro, sellersk.it, FBA MultiTool) keep us honest. We deal with production issues, user feedback, and real-world scale every day.
We maintain what we build
We don't just ship and walk away. Monitoring, incident response, deployments, infrastructure — full SRE ownership of production systems, not just code handoff.
Open source first
We maintain CRXJS (3.9k stars), contribute to Allegro Tech and Hangfire, and publish tools that others depend on. Giving back is part of how we work.
Fixed pricing, no surprises
After a short workshop we give you a fixed quote for the agreed scope. You know what you pay before we write the first line of code.
Transparent, iterative delivery
You always know what's happening. Progress is visible as it happens — no month-long silences, no big reveals. If something needs to change, we talk about it immediately.
Let's discuss your project
Whether you need a custom browser extension, a dedicated dev team, or technical consulting — let's find the best approach together.
