Dmytro Plavutskyi — Founder of Ryntra, Squadic and RefKit
Three products.One hard problem.
AI can generate almost anything. I build the products for what comes after: making the result understandable, controlled and provable. Ryntra, Squadic and RefKit each take one part of that.
01 — Projects
What I'm building.
Three products, in the order I give them attention. Each card links to the live product.
Risk, strategy and evidence OS: control the decision, authorize the action, prove the outcome.
AI product & language mastery: take your product apart, find the gaps, rehearse the explanation.
Visual contracts for AI coding agents: borrow, keep, lock — then measure what actually rendered.

Status, not a schedule. A line changes when the product changes — no release dates are promised here.
04 — Work
How each of these was built.
Case studies for everything I have built, including the products and client projects that came before. Honest statuses, explicit boundaries — a record, not an offer. I no longer take client development work.

05 — About
About me.
I'm Dmytro Plavutskyi. I design, build and ship my own products — strategy, interface, code and release, end to end. There is no team behind the byline; there is one person who is accountable for the result.
The thread across all three products is the same. A model can produce output. Someone still has to decide whether it is true, whether it is permitted, whether a human actually understands it, and whether the outcome can be proven afterwards. That is the part I build.
I work from Ukraine, for users anywhere. What I publish here is what actually exists — statuses are honest, and what is unbuilt is named as unbuilt.
