About

My name is Roman Boiko. I’ve been building software for more than twenty years — across research, startups, enterprise, and small business work.

The site uses "we" because the business is built to grow — but right now, I'm doing all development and running it solo.

Over time, software tends to get harder to understand and maintain. Leanersoft pushes the other way — making it leaner via technology and thoughtful development choices.

A few things we treat as non-negotiable:

• Data sovereignty — your data stays yours. No lock-in, no hostage formats, no silent dependencies on someone else’s infrastructure.
• Privacy by choice — no tracking by default. Telemetry is opt-in, not opt-out.
• Performance — speed is a feature, not an afterthought. If something feels slow, it is broken.
• Plain-language trade-offs — every decision has costs. We would rather explain them than hide them behind convenience language.

That runs through both sides of the business, and they reinforce each other. Semnote is a document platform built around local files, readable formats, and clear structure — it is where those principles become a product. The services side applies the same standard to client work: build what is needed, keep the setup understandable, and leave the client with something they can run and change without us.

I work directly with clients — no account managers, no handoffs, no layers. If you want senior technical work from someone who will be straight about scope, cost, and trade-offs, that's the offer.
